Publisher: 2010Dissertation note: We examined the effects of feeding pre-starter crumble diets for a period of 1 to 10 days. One hundred and fifty day-old broiler chicks (Hubbard Classic) were purchased and the birds were divided into five groups (A, B, C, D & E) with three replicates having ten chicks each. Diets were fed with different metabolizable energy (varied from 2750 to 2850 kcal of ME/kg) but same crude protein level (21%) with different lysine levels (varied from 1.3 to 1.5%). After 10 days single starter and finisher crumble diets were fed to the birds up to 28 and 35 days of age respectively. A linear effect of ME from 2750 to 2850 was found on body weight in Treatments A (ME=2750kcal/kg; CP=21%; lysine=1.4%), B (ME=28000kcal/kg; CP=21%; lysine=1.4%) and D (ME=2850kcal/kg; CP=21%; lysine=1.4%) after 35 days of age. Minimum growth was observed in Treatment E (ME=2850kcal/kg; CP=21%; lysine=1.5%) after 35 days of age. There was linear improvement in feed intake in groups C, D and E with higher ME i.e 2850 and varying lysine from 1.3, 1.4 and 1.5% respectively and this trend remained same from 0-35 days of age. Better FCR with good body weight were observed in treatments B and D with FCR 1.78 and 1.75 respectively at the end of experiment. Statistical analysis of body weight after first week revealed significant difference (P<0.05) among the treatments B and C. Statistical analysis of body weight after 35 days revealed significant difference (P<0.05) among A, C, D and E. Statistical analysis for Body composition, organs weights, G I tract and Intestinal weights revealed non-significant differences (P>0.05). This study indicates that it is better to increase energy up to 2850kcal/kg with lysine 1.4 % in pre-starter diets for better performance, gut development, dressing percentage and above all a good start for good overall performance at 35 days of age.

Publisher: 2010Dissertation note: Livestock doles out 51.8% of agricultural value added and it shares 11.3% to national GDP. Livestock supports the lives of 30-35 million people in rural areas. The total population of cattle, buffalo, sheep and goat in the Pakistan is 33.0, 29.9, 27.4 and 58.3 millions, respectively. The beef and mutton production is 1,601 and 509 thousand tons respectively. The milk production from cow, buffalo, sheep and goat is 14,982, 27,028, 36 and 719 (000 tons) (Anonymous, 2009). The livestock sector of Pakistan is very important. It is the rich source of food items like milk, meat etc. and also provides raw material to industry like leather, wool, bones, hair etc. Livestock production mainly depends on two factors; management and nutrition. The provision of feed stuffs of adequate balanced nutrition is likely to be the most limiting factor in increasing livestock production. One of the vital components of nutrition is minerals which play important role in various body functions and body structures of animals. Minerals' deficiency is the major problem of livestock and its estimation in blood, soil, forages will be helpful for providing balance nutrition to livestock. The basic aim of the study was to identify the imbalance and deficiencies of micro mineral (Zinc) in livestock of two districts of Punjab province. For this purpose, samples of blood, water, soil, crops and feed stuffs were taken. For the purpose of sampling, each district was divided into five sub-locations and these were considered as representative area of the district. Samples were taken from each sub-location.
These samples were brought to laboratory for analysis. For analysis of minerals, Atomic Absorption Spectrometer was used. Samples were analyzed for Zinc. The maps were developed on basis of geographical distribution of the Zn in soil, water, forages and animals' status with the help of GIS technology based on Global Positioning System. This study was helpful in providing the information about the present Zinc status in livestock of two districts to formulate rations and premixes. The data thus collected was subjected to one-way anova and t-test (Steel etal, 1997).
Significant (p<0.05) difference was observed between summer and winter seasons for Zn in plasma of goats and Kids in Hafizabad and Okara districts. Significant (p<0.05) difference was seen in Zn status of plasma of sheep, buffalo and cattle during all physiological stages between summer and winter seasons in Hafizabad and Okara districts. Significant (p<0.05) difference was found in Zn status of plasma of lambs during winter and summer seasons between Hafizabad and Okara districts. Non significant (p>0.05) was observed for Zn value in plasma of goat, kids and sheep during summer and winter season between Hafizabad and Okara districts. Significant (p<0.05) difference was seen in lactating cattle and young stock buffalo during both seasons and in young stock cattle during winter season between Hafizabad and Okara districts. Non significant (p>0.05) difference was observed in lactating, dry/pregnant buffalo and dry/pregnant cattle during summer and winter seasons between both districts. The highest value of Zn was seen in young stock buffalo (1.43 ± 0.15 ppm) in Hafizabad district during winter season and the lowest value was found in sheep plasma (0.70 ± 0.01 ppm) during summer season in Okara district. The highest value for Zn level in the soil is found in Hafizabad district (4.10 ± 0.02 ppm) during winter season and in Okara district (3.16±0.07 ppm), during summer season. The overall value of Zn for summer and winter seasons was highest for Hafizabad (3.47 ± 0.05 ppm) district. In wheat fodder, the highest value of Zn was seen in Hafizabad district (0.0228 ± 0.005 mg/kg) and for Sorghum fodder highest value was observed in Okara district (374.0 ± 177.4 mg/kg). In corn grain, the highest value of Zn was seen in Okara district (0.0288 ± 0.002mg/kg). The highest value for wheat grain was observed in Hafizabad district (680 ± 216.2 mg/kg) and for rice grain in Okara district (55.2 ± 24.9 mg/kg). In wanda, significant (p<0.05) difference was observed between both districts.

Publisher: 2010Dissertation note: A series of experiments were envisaged to evaluate the effect of supplementation of dietary electrolytes with applicability of dietary electrolyte balance by using different salts on growth and carcass responses, body physiological responses and litter condition of modern day broiler chickens under phase feeding system.
Day-old straight-run Hubbard broiler chicks were randomly allocated to eight dietary treatments replicated four times in such a way that a floor space of 0.09 m2 was provided to each bird. Birds were housed in environmental control system. Continuous light was provided 24 hours for the first 3 day and thereafter a light pattern of 23L:ID was adopted for the entire experimental. In each experiment, a basal diet was formulated having lowest level of each electrolyte. In experiment 1, Na and DEB in the basal diet were maintained at 0.08% and 160 mEq/kg, respectively. This basal diet was then supplemented with sodium bicarbonate (NaHCO3) and disodium sulphate (Na2SO4) to maintain four levels of Na (0.17, 0.26, 0.35, and 0.44%) by fixing K and Cl with DEB 200, 240, 280 and 320 mEq/kg, respectively. In experiment 2, a basal diet was prepared to contain the lowest level of K and DEB i.e. 0.70% and 160 mEq/kg, respectively. This basal diet was supplemented with potassium sulphate (K2S04) and potassium carbonate (K2C04) by fixing Na and Cl. So, four levels of K (0.86, 1.02, 1.18, and 1.34%) were maintained in eight dietary treatments. In experiment 3, a basal diet was prepared to contain the lowest level of Cl and DEI3 i.e. 0.17% and 320 rnEq/kg, respectively. This basal diet was supplemented with ammonium chloride (NH4CI) or calcium chloride (CaCl2), so that, in each diet, we can have the increase of 40 mEq/kg DEB at 0.3 I, 0.45, 0.59 and 0.73% of Cl at DEB 280, 240, 200 and 160 mEq/kg, respectively, by fixing Na and K.
At the end of each phase (pre-starter, starter, grower and finisher); data of feed intake, weight gain, feed to gain ratio, mortality, water intake, water intake-to-feed intake ratio and litter quality were collected and evaluated. At the end of each experiment, two birds were slaughtered for their carcass and body physiological responses. Blood was also collected from these same birds for blood pH. glucose and serum mineral analyses. For statistical analyses, four (4) levels of electrolyte were used with two (2) sources of salt in a factorial arrangement of 4 x 2 under completely randomized design using GLM.
In experiment 1, highest weight gain and feed intake were found in birds consuming 0.17% (NaHCO3) and 0.44% (Na2SO4) dNa, respectively during d 1-10. However during d 11-20, weight gain and feed:gain were reduced with same levels of dNa. Maximum weight gain was found in diets containing 0.17 and 0.24% dNa during d 21-33 and 34-42, respectively. Improved FG was the result of diets containing 0.20% (NaHCO3) and 0.37% (Na2SO4) dNa during d 2 1-33. Linear rise in water intake was observed in birds with increasing dNa during d 1-42. Minimum litter dampness was seen at 0.37% (NaHCO3) and 0.2 1% (Na2SO4) during d 1-10. Minimum and maximum mortality were observed at 0.37% level of dNa in case of supplementation of NaHCO3 and Na2SO4, respectively. Significantly increased pH and kidney weight while reduced dressing percentage were observed by amount and salt of dNa. Increased breast, thigh and gizzard weights were observed with increasing sodium. Weights of pancreas, gall bladder, bursa, and lungs, and shank length were affected by interaction of amount and salt of dNa.
In experiment 2, BWG (P0.03) and feed:gain (P0.05) was improved at 1.20% dK during 32 to 42 d of age. K2S04 supplemented diets increased feed intake during I to 10 d (P<0.05), water intake during 34 to 42 d (P0.04) and mortality during 1 to 42 d (PE0.02). Water intake was increased linearly with increasing dK when supplemented by K2C03 whereas this was decreased linearly with increasing dK with that of K2S04 during 11 to 20 d (P0.002). The K2S04 supplemented diets lowered the blood pH (P0.00l), dressing (P0.04), abdominal fat (P0.03) weights and shank length (P0.02). A significant salt x dK effect was observed where low levels of dK with K2C03 and high levels with K2504 exhibited lower litter moisture during all phases. Increasing concentration of serum cations was observed by increasing dK, by balancing of increasing serum HCO3 with decreasing Cl at the end of the experiment.
In experiment 3, body weight gain and water consumption were optimized at 0.73%, and 0.73% (CaCI2) and 0.45% (NH4CI), respectively, during d 1-10. During d 2 1-33, maximum weight gain and feed intake were observed at 0.42%, and 0.63% (CaCI2) and 0.63% (NH4CI), respectively. Highest weight gain (0.60% dcl), feed intake (0.61% CaCI2 0.42% NH4CI) and mortality (0.73%) while improved feed:gain (FG; 0.38% dCl) were obtained by interaction effects of amount and source of dCl during d 34-42. Fl (0.60%), feed:gain (0.3 8%) and litter moisture (0.31% NH4CI; 0.35 CaCl2) was affected during I -42d by amount of dcl. Increased blood pH, serum glucose and dressing percentage were found by dCl and replacing CaCI, with NH4C1. Improved breast meat, thigh meat and shank length while reduced abdominal fat were observed by replacing salts (CaCI2 withNH4Cl).
It is concluded that birds showed better growth performance and reduced mortality against high levels of dietary sodium in Na2SO4 than NaHCO3 supplemented diets, while significant rise in pH, breast and thigh meat yield while reduced dressing percentage were observed with increasing dietary sodium. The importance of high concentration of dK for better weight gain and feed efficiency was depicted in later stages of production. K2C03 increased survivability and dressing responses but both dK levels and salts played important role for water intake, litter condition, carcass characteristics and serum mineral concentration. Birds were also suggested to be more sensitive to amount and source of dC1 in later part of their life.

Publisher: 2011Dissertation note: Buffalo is an important animal which contributes approximately 50% meat in Pakistan. Traditional system of meat production is inefficient. About 50 % of the male calves die during the first week of their life. Some calves are raised to 60-80 kg on extremely poor and unbalanced diets and only a few are raised to about 200 kg of live weight with very low average daily gains. Most of the meat produced in the country comes from end of career, or emergency slaughtered animals. To improve meat production in country calves are required to be fattened through feed lot system. Energy-rich sources available in Pakistan include cereal grains (wheat, maize, barley, oats, sorghum, and rice), wheat bran, rice polishing and molasses etc. At the same time fats and oils are also rich source of energy and infrequently used in animal feeding. Molasses, a by product of sugar industry, is an excellent and cheaper source of energy. An objective of the study was to compare efficiency of energy sources for meat production. For this purpose, a fattening trial was conducted on 15 Nili-Ravi buffalo calves of approximately the same age and weight to study the comparative efficacy of three different energy rations. Animals were divided into 3 groups of 5 calves each. Animals were offered three different rations. The experiment was carried out for 90 days. Group A was fed TMR having molasses as energy source, group B was fed TMR having com grain as energy source and group C was fed TMR with rumen protected fat as energy source. Daily feed consumption, body weight gain, feed conversion ratio, economics and blood parameters (blood glucose, total protein, urea and creatinin) were studied. The Data obtained was analyzed under CRD through ANOV A and the difference among treatment means were tested with LSD. The average weekly growth rate of group A, B and C was 6.23±0.187, 6.l85±O.l87 and 6.08±0.187 respectively. The average daily growth rate of group A, Band C was 0.89, 0.88 and 0.87 kg respectively. Total Mixed Ration taken by group A, B and C was 2064.5 kg, 2546.01 and 1993.7 kg respectively. The average daily feed intake was 4.59 ±O.l06, 5.66±0.106 and 4.43±0.106 kg per day of group A, B and C respectively. Group A, C had non significant difference (P>0.05) from each other while group B was significantly different from group A and C. The feed conversion ratio of group A, B and C was 5.16 ±0.25, 6.40±0.25 and 5.10±0.25 respectively. The results showed that calves fed ration C has highest FCR than ration A and B. The results of the study revealed non significant difference in the concentration of serum urea, creatinine, glucose and serum total protein among the experimental animals. The cost of one kg live weight for group A was Rs 78.73 while Rs 102.78 and Rs 129.1 for group Band C. The results showed th~t ration A was more economical than ration Band C. The findings of this study showed the benefit of utilization of different energy sources in the fattening ration of calves. Due to higher prices and demand of cereal grains, other cheaper sources such as molasses can be used for fattening as energy source. If there is unavailability of molasses and cereal grains then bypass fat (Berga fat) can be used for fattening purpose. The study revealed that each energy sources is equally effective.

Publisher: 2003Dissertation note: Poultry feed is mainly composed of cereals and vegetable proteins, which cannot be fully digested and utilized by poultry due to lack of endogenous enzymes. As feed costs 70% of total poultry operation, so there is need reconsider enzyme supplementation in such feeds. For this purpose, a total of 800 day old Hubbard broiler chicks will be randomly selected, weighed, and assigned to 5 dietary treatments with 8 replicates per treatment. Feed was procured from a commercial feed mill, comprising of a control diet (2750 Kcal/kg energy with no Allzyme SSF), two negative control diets (Negative Control Diet-I and II having 2700 Kcal/kg and 2675 Kcal/kg energy having no Allzyme SSF) and two positive control diets (2700 Kcal/kg and 2675 Kcal/kg energy having Allzyme SSF @ 200gms/ton).
The average body weights of broilers at different ages showed that broilers of group A attained maximum weight, which was followed by group D, B, E and C, respectively, revealed that the weights of group B, C and E were significantly different from group A, whereas, the differences of group A and D were found non significant that maximum feed consumption was exhibited by group B followed by group C, E, D and A. The data of feed consumption when subjected to analysis of variance showed significant difference (p<0.05) of group B and C with groups A, D, E, while the feed consumption of group B and C was found insignificantly different from each other. The overall FCR of group A was found to be the best among all groups. Next to this was group D, followed by group E, B and C. It is evident from the results that FCR of broilers in group D was very near to control group A, showing activity of enzyme complex in terms of performance.
The highest toe ash percentage (10.83%) was recorded in broilers of group D which was fed diet with 0.1% less available phosphorus and 0.1% calcium but added 200gm/ton enzyme complex, lowest toe ash percentage (9.98%) was recorded in group C which was fed with diet having 0.1% less available phosphorus and 0.1% calcium than control group A with no enzyme complex supplementation. The highest Ca content in plasma was observed in group A, whereas the lowest Ca plasma content was recorded in group B. Phosphorous content in plasma of group D was found to be highest among all the groups followed by E, A, B and C.
No bird had showed any kind of leg weakness/deformity. Critical analysis of the data indicated that birds of group D were reared at lowest feed cost and this diet was found most economical.
Cost of production of feed and per kg live weight can be decreased by use of enzyme complex in feed.

Effect Of Feeding Citrus Pulp Silage On The Growth Performance Of Sahiwal Calves
by Muhammad Iqbal | Prof.Dr.Talat Naseer Pasha | Prof. Dr. Makhdoom Abdul Jabbar.
Material type: ; Format:
print
; Nature of contents: ; Literary form: Publisher: 2011Dissertation note: Livestock is contributing about 53 per cent of agricultural value added and 11.4 per cent to the national GDP with a total animal heads of 157.3 million but feed availability of crude protein (CP) and total digestible nutrients (TDN) is deficient by 38.10 and 24.02%, respectively. However, a decline in domestic feed resources and the need for Pakistan's livestock production to become internationally competitive are strong reasons for promoting the use of alternative locally available and cheap sources of feed ingredients, such as citrus pulp from fruit processing industry which do not attract competition in consumption between humans and livestock. The primary objective for the use of these by-products is to reduce the feed cost and consequently cost of producing a unit of the product like milk or meat as well as to fulfill the nutrients demands of animals. Citrus pulp is a by-product widely available in Pakistan and is mainly discarded as waste. Its cost is relatively low compared to its nutritive value but is seldom used as ruminant feed. The large amounts which are available during the harvesting season can be ensiled in combination with dry roughage, to get the required moisture level of it. So in the present study citrus pulp with wheat straw was ensiled and the silage was fed to Sahiwal calves to observe its intake, weight gain as well as economics. Results of the present study revealed that the optimum level of 20% citrus pulp in feed gave good results while intake and weight gain decreased for 30% citrus pulp in feed. Average total weight gain were 27.5, 37.5, 28.75 and 23.75kg for ration A, B, C and D, respectively (containing 10, 20 and 30 citrus pulp, respectively). Average daily gain for group A, B, C and D were 0.44, 0.60, 0.46 and 0.38kg, respectively and the difference was statistically significant (P < 0.05). When average daily feed intake for each calf was calculated on dry matter basis it showed 4.40, 4.50, 3.39 and 3.13kg respectively for group A, B, C and D which was not significantly different between diets. By ascertaining the cost of the feed for ration groups it showed significance difference having average cost of production per animal per kg body weight 37.07, 23.80, 21.68 and 25.58 Rs for group A, B, C and D, respectively.

Publisher: 2011Dissertation note: Poultry is one of the vibrant segments of agriculture sector of Pakistan. Its contribution in agriculture and livestock is 4.81% and 9.84%, respectively. Poultry meat contributes 23% of total meat production of Pakistan. Poultry sector has shown a healthy growth at the rate of 8-10 percent annually. For optimum production and health, animal receive a balance diet that supplies nutrient at desired concentration. Organic trace minerals have been used in broiler feeds, showing promise in improving growth performance, bird health, processing yield and meat quality characteristics. Interest is also building in using organic trace minerals in place of a portion of the feed inorganic mineral supplement in order to get maximum growth and health with lower levels of mineral intake, thus lowering the amount of minerals excreted from the birds.
The average feed consumption based on gram/bird at different ages showed that maximum feed consumption was exhibited by group F followed by group E, D, C, B and A. The data of feed consumption when subjected to analysis of variance showed significant difference (P<0.05) feed intake was during first three weeks but during the last two week non significant difference was observed in feed. The feed intake in group supplemented with organic trace minerals was significantly different from that group supplemented with inorganic trace minerals.
The average body weights of broilers at different ages showed that broilers of group A attained maximum weight, which was followed by group B, C, D, E and F, respectively. . Statistical analysis of the data revealed a significant (P<0.05) difference in weight gain due to treatments. The weight gain in group supplemented with organic trace minerals was significantly different from that group supplemented with inorganic trace minerals.
The overall FCR of group A was found to be the best among all groups. Birds in group B performed better than rest groups i.e., C, D, E and F. The analysis of variance among various experimental groups during 1st three weeks revealed a non significant difference between all groups i.e., A, B, C, D, E and F, however, FCR was significant difference (P<0.05) during last two weeks.
Result obtained showed significant differences in carcass characteristics i.e., shank length, keel length, bursa weight while non significant differences in dressing percentage, liver weight, heart weight, spleen weight and gizzard weight due to supplementation of organic minerals. Statistically significant differences were found in shank and keel length with supplementation of organic minerals, however non significant differences were found in shank and keel length in groups feeding inorganic trace minerals. The bursa weight of the birds in group supplemented with organic trace minerals was significantly lower from all groups, however non significant differences were observed in among birds in group supplemented with inorganic trace minerals.
The economics of production of broilers in different experimental groups A, B, C, D, E, and F showed that average cast of production remained 43.40, 43.50, 46.10, 45.36, 44.91 and 45.66 per kg live weight. Higher cast of production was observed in group C (46.10) and F (45.36) while group A (43.40) was having the lowest cast of production which showed significant differences from all other groups.
As the proximate analysis of broiler thigh and breast meat is concerned, Dry matter, moisture percentage and ash percentage of both breast and thigh portion of broiler meat for group A, B, C, D and E showed non significant differences among all treatments, while the data on crude protein and ether extract in breast and thigh part of meat of broiler when subjected to analysis of variance showed significant difference (P<0.05) among treatment groups A, B, C, D, E and F group.

by Muhammad Shakeel Anwar | Prof.Dr.Talat Naseer Pasha | Dr. Jalees | Prof. Dr. M. A. Jabbar.
Material type: ; Format:

Publisher: 2011Dissertation note: At present, 121.1 million heads of animals in Pakistan annually require about 10.9 and 90.36 tons of crude protein (CP) and total digestible nutrients (TDN), respectively. However the respective availability of these two nutrients is 6.7 and 69.0 million tons and thus, CP and TDN are 38.10 and 24.02% deficient per annum. For economical production of balanced feed for livestock, poultry, fish and pet animal, non-conventional feed resources need to be explored to find solution to the existing gaps. For this purpose the present study was conducted to determine the nutritional profile, processing and utilization of rumen contents for fattening of male Lohi lambs. The study was conducted in three phases. In phase one, bovine rumen contents were collected from the slaughter house near Bakar Mandi and were analyzed at Nutrition laboratory, UVAS, Lahore in triplicates before ensiling. In phase two, ensiling of wheat straw (Urea treated @4% of DM of wheat straw and also another ensiling without urea treatment) along with rumen contents will be done with or without 7% addition of molasses for minimum 60 days at Ravi Campus, Pattoki. pH of silages1,2,3&4 after 60 days was 4.78,4.70,4.92 and 5.11 respectively. The silage containing rumen contents and wheat straw showed a increase in C.P as compare to simple rumen contents and silages which were urea treated have significant (p<0.05) increase in C.P. In phase three, a metabolic trial was conducted at Ravi Campus Pattoki, in which 25 male Lohi lambs were fed the diets having total mixed ration (100%TMR) (Tc), 70%TMR with 30% silage1 (T1), 70% TMR plus 30% silage2 (T2), 70%TMR with 30% silage3 (T3), and70% TMR plus 30% silage4 (T4). The data thus obtained was statistically analyzed using one way analysis of variance (ANOVA) technique. The significant differences between means were tested by Duncan's Multiple Range test. DM intake was significantly (P<0.05) higher in control group than other groups offered silages containing rumen contents. There was non significant difference (P>.05) in DM intake between T1.T2 & T3. T4 was non significant to all other treatments. Statistical results showed non significant difference (P>.05) in total weight gain among all the treatments however maximum weight gain was observed in control treatment. Feed efficiency was also non significant (P>.05) among all the treatments. So we can use processed rumen contents as cheap protein source in small Ruminant feed. There were no harmful effects on health of lambs during whole trial. So we can replace 30% of conventional TMR with Rumen Contents safely.

Effect Of Feeding Of Different Non Protein Nitrogen (Npn)Sources On Performance Of Lactating Nili- Ravi Buffaloes
by Muhammad Salman Nadeem | Prof.Dr.Talat Naseer Pasha | (Prof. Dr. Makhdoom Abdul Jabbar).
Material type: ; Format:

Publisher: 2011Dissertation note: The feed resources in Pakistan are comprised of green fodder / pastures (mostly on canal banks and on road sides), dry roughages (mostly wheat and rice straw) and conventional concentrates. Furthermore, it has been reported that conventional feedstuffs are very low in non-protein nitrogen (NPN) sources. These circumstances attracted the attention of nutritionists and farmers towards the use of slow-releasing non-Protein Nitrogen sources in the livestock feed. The experimental study was conducted at LPRI Bahdurnagar Okara. Feed was reformulated by addition of urea and Optigen. Samples in triplicates were analyzed at Nutrition laboratory, UVAS Lahore and LPRI, Bahadurnagar, Okara. The crude protein of the concentrates A, B and C were 17.03, 17.03 and 17.04 respectively. Eighteen lactating Nili-Ravi buffaloes were divided in three equal groups using completely randomized design. Each group was fed on isonitrogenous concentrate to find out its effects on performance of lactating buffaloes. The data thus obtained were statistically analyzed using one way analysis of variance (ANOVA) technique. The significant differences between means were tested by least significant difference test. Milk production was higher in group C feeding with reformulated with 1% Optigen. The highest individual milk fat was higher for group C. The average protein percentages of all the buffaloes were non-significant. The milk urea nitrogen level was higher in group B. The blood urea nitrogen level was higher in group C. It was concluded that the use of Optigen in buffalo feed improved the milk production significantly without affecting the milk composition. It can replace the conventional NPN sources without any adverse effects on health of buffaloes. Optigen can be used as economical and affective slow release NPN source.

Publisher: 2011Dissertation note: The cost of feed, as percentage of total production costs, accounts for about 50-60% of ruminant feeding systems. According to estimates, Pakistan is deficient by 40 and 80 percent in forage and concentrate feeds. For economical production of balanced feed for livestock, poultry, fish and pet animal, non-conventional feed resources need to be explored to find solution to the existing gaps. For this purpose the present study was conducted to determine the nutritional profile, processing and utilization of rumen contents in buffalo feed. The study was conducted in three phases. In phase one, bovine rumen contents were collected from the slaughter house near Bakar Mandi and were analyzed at Nutrition laboratory, UVAS, Lahore in triplicates befor ensiling. In phase two, rumen contents were ensiled with wheat straw, with and without addition of 6% molasses for a period of 60 days at Ravi Campus, Pattoki. Wheat straw was also treated alone by reducing its DM to 44% with water and by addition of 6% molasses. The pH of silages 1, 2, 3, and 4 was 4.78, 4.70, 4.92 and 5.11 respectively. The silage containing rumen contents and wheat straw showed a increase in C.P as compare to simple rumen content and silage which were urea treated have significant (p<0.05) increase in C.P. In phase three, a production trial was conducted at Buffalo Reaearch Institute, Pattoki, in which 25 lactating Nili-Ravi buffaloes were fed the diets having total mixed ration (100%TMR) (Tc), 70%TMR with 30% silage1 (T1), 70% TMR plus 30% silage2 (T2), 70%TMR with 30% silage3 (T3), and70% TMR plus 30% silage4 (T4). The data thus obtained was statistically analyzed using one way analysis of variance (ANOVA) technique. The significant differences between means were tested by Duncan's Multiple Range test. The DM intake was significantly higher in control group and silage without molasses and urea. Milk production was higher in group feeding with silage4 which was treated with urea and molasses. There was also significant increase of milk production in group feeding with silage1. It was concluded that rumen contents could replace the conventional TMR without any adverse effects on health of buffaloes.
