Publisher: 1987Dissertation note: The study conducted at the College of Veterinary Sciences, Lahore was aimed to compare the Desi fowl (Rural breed) and Fayoumi (Egyptain breed) for the selection of breed best suited for meat production. The basis of the selection were body weight, feed consumption, feed efficiency, production cost, slaughter analysis and chemical composition of the carcass.
120 eggs of the Desi breed were collected from the deep rural areas of Punjab and the same number of eggs of Fayoumi breed was obtained from Government Poultry Farm Lahore. These Eggs were hatched in the Animal Husbandry section, College of Veterinary Sciences, Lahore. Sixty birds each of Desi and Fayoumi breed were divided into three replicates and reared under controlled managemental conditions upto 16 weeks of age. Broiler starter ration was fed ad.libitum during the first 8 weeks of age and broiler finisher ration during the last 8 weeks of age.At the 8th, 12th, and 16th week of age 3 birds from each group were taken randomly and slaughtered. The slaughter analysis and chemical composition of the meat was studied (Richard, 1984). The data wa subjected to two way analysis of variance and 2*2*3 factorial. There was no significant difference in body weight upto 10 weeks of age but Desi breed gained significantly more body weight from 11th to 16th week of age. Feed consumption and feed efficiency of Desi breed was highly significantly better as compared to Fayoumi birds. Mortality was found to be more in Desi birds and production cost was more in Fayoumi. Non significant differences were found between the breeds in Dressing percentage, Giblet, Liver, Gizzard, and Heart weight. Breast meat percentage, Shank and Keel lengths were also non significant between the breeds. However there were highly significant between the breeds during 8th. , 12th, and 16th week of age. Bone meat ratio was highly significantly more in Fayoumi breed. Breast width was more in Desi and the difference between the breeds was significant. Correlations of breast meat,shank and keel length with body weight were found higher in Desi breed.
Chemical analysis indicated non significant differences between the breeds in moisture and crude protein contents; although apparently moisture percentage was higher in Fayoumi and protein were notices more in Desi Breed. Lipid percentage was higher in Fayoumi fowl at 8th week of age whereas it increased at the 12th and 16th week of age in local fowl and significant difference between the breeds was observed. The Percentage of ash was significantly more in Fayoumi breed. On the whole the results of the study indicate better overall performance by Desi birds.

Publisher: 1983Dissertation note: The aim of this experiment was to study the effect of various floor spaces on the performance of broilers kept in cages. One hundred and twenty day old (Indian River of Hybred Pakistan Ltd) chicks were reared for the experimental units of 36 birds each and were kept on 0.5, 0.75 and 1.0 sq. foot floor space per bird. They were fed on a commercial ration. The other conditions like temperature, humidity, light and ventilation were similar for all the groups.
The broilers at the end of 8th week, gained an average live weight of 2.023,2.054 and 2.063 kg with a feed conversion ratio of 2.45, 2.43 and 2.41 at densities of 0.5, 0.75 and 1.0 sq. foot per bird respectively. No significant difference was observed on the three different floor spaces of 0.50,0.75 and 1.0 square foot per bird on cages for feed efficiency. The mean dressing percentage recorded were 64.3, 65.9 and 66.9 at 0.5, 0.75 and 1.0 sq.foot of floor space respectively at the end of experiment. The differences in dressing percentage were also statistically non significant.
It is worth mentioning that no mortality was observed during whole of the experimental period.
Suggestions
At the end of experiment it was found that broilers can be reared in cages at a density of 0.5 sq. foot efficiently and economically up to the age of 8 weeks without any detrimental effect on the growth rate and feed conversion ratio. It is therefore recommended that the broilers should be kept at 0.5 sq. foot per bird in cages.

Publisher: 1981Dissertation note: An experiment was designed to study the effect of population density on the weight gain, feed efficiency, dressing percentage and carcass chemical composition of the broilers at 8 weeks of age. One hundred day-old (Hubbard) chicks were reared in the floor pens with wood litter for 2 weeks, after 2 weeks 90 chicks were selected and were randomly divided into 3 groups of 30 chicks each. Each group was further sub divided into three replicates of 10 chicks of groups were placed at densities of either 0.5, 0.75 and 1.0 square foot per bird up to 8 weeks of age. Other conditions were the same for all the groups.
Data was recorded in respect of body weight gain, feed efficiency. The average gain in body weight per bird at 8 weeks of age was 1827, 1878 and 1894 gm on 0.50, 0.75 and 1.0 square goot space per bird, respectively. The feed efficiency values were found to be 2.19, 2.21 and 2.21 for the birds kept on 0.50, 0.75 and 1.0 square foot floor space per bird, respectively.
Differences in weight gain and feed efficiency were no significant.
At the end of the study, 3 birds from each groups were randomly taken, slaughtered, dressing percentage calculated, the meat was analysed for approximate analysis of other extract, protein and ash percentage.
However the difference due to the effect of various floor spaces were found no significant except in other extract percentage, which was more in birds kept at 0.50 square foot floor space per bird due to restricted movements. The results of present experiment showed that there was no determental effect due to different floor spaces on the performance of broiler, however, the birds kept at 0.50 showed soiled plumage and about 10 percent showed breast blisters.

Publisher: 1989Dissertation note: Poultry industry I Pakistan, has been commercialized shoeing an annual increase of 15 percent for the last ten years (Pak. Economic Analysis Network Project 1988). The poultry farming is the quickest, efficient economical and comparatively cheapest source of good quality protein. Although a considerable work has been done on various aspect of their rearing in our local environmental and managemental conditions, yet some areas remained unexplored. One of these areas was the study on comparative productive performance, qualitites and chemical composition of carcass of various commercial broiler strains, in relation to sex and age.
In the present study, four different strains and sexes of Ross, Lohmann, Indian River and Hubbard were evaluated and compared for productive performance and carcass characteristics at different age periods. A total of 240 one day old, Sex separated chicks with equal number (60) of each strain were reared for a period of 8 weeks, under indentical managemental conditions. Among male birds Hubbard gained highly significantly (P<0.01) more weight than that of other strains, while non-significant difference (P<0.05) was found between Ross and Lohamann and showed significantly better weight gain than the Indian river strain. Females birds of Hubbard strain had also gained significantly (P<0.05) more weight than that of other strains, while non significant difference was found among the females of rest of the three strains. The results on weekly feed convertion ratio were found to be non significant (P<0.05) due to strain and significant due to age of the birds . While among sexes it was found that male birds of each strain showed better F.C.R compared with that of female chicken.
The dressing percentage increased significantly with age, male birds of the strain showed better dressing percentage compared with the female birds of the respective strains though statistically the diference was found to be non-significant (P<0.05).The birds of Hubbard strain showed significantly better dressing percentage than that of the other strains. A significant difference was also observed between Lohmann and Indian River strain while the difference between Ross and Indian River was statistically non-significant as was the difference between Ross and Lohmann strain (P<0.05). The values for weight of Giblet of Ross, Lohmann and Indian River Strain were non-significantly different (P<0.05) from each other but were significantly poor than that of Hubbard strain. A non-significant difference in shank length was observed among various strains (P<0.05). Non-significant difference in length of kell bone was found among birds of Ross, Lohmann and Indian River Strain while birds of both sexes of Hubbard strain had significantly (P<0.05) greater length of kell boe. Moreover it was observed that female birds of all the strain had greater length of keal bone compared with male birds of their respective strains. Female birds of all the strain had significantly greater bone, meat ratio compared with the male birds of their respective strains. Birds of Ross. Lohmann and Indian River Strain Had significantly lesser meat bone ratio than that of Hubbard strain (P,0.05). Difference in meat bone ratio between Lohmann and Ross strain was found to be statistically significant, but non-significant between Lohmann and Indian River strains (P<0.05).
The effect of strain, age and sex on the composition of carcass revealed that moisture percentage was not significantly affected by strain and sex. However it decreased with increase in age. Crude protein contents generally increased with age in both sexes of all the four strains. Protein percentage was found to be similar between both the sexes of all strains. Fat contents increased with age In all the four strains. Female broilers of all strain had significantly greater fat contents than the male broilers (P<0.05). Between the male and female broilers Hubbard strain had significantly more fat percentage, followed by Indian River, Ross and Lohmann. There was no effect on the ash contants of carcase due to sex and strain, though it decreased with increase in age.

Publisher: 1988Dissertation note: The study was aimed to find out the effect of different light intensities (wattages) on weight gain, feed consumption feed conversion ratio, dressing percentage, mortality and abnormalities in broiler chicks. 120, one day old chicks were selected and divided randomly in four groups of 30 chicks each. The following light treatments were provided to the chicks of the Groups A,B,C and D. (A) 40 watt bulb at night and natural day light (B) 25 watt bulb at night and natural day light (C) 15 watt bulb at night and natural day light (D) Spot-lighted feeders with 5 watt bulb at night and natural day light. Each chick was given 0.8 sq. ft. floor space. Feeding and watering were provided ad.lib. under indentical managemental conditions.
Weekly data starting from 4th week onwards revealed that at 4th week of age there wa non-significant difference in weight gain, feed consumption and feed convertion ratio among the four treatment groups. Significant differences in weight gai and feed conversion ratio and non-significant differences in feed consumption were noticed among the groups at 8th week of age.
The results indicate that birds of Group A due to more activities under high wattage gained least weight i.e. 1.6937 Kg and sonsumed more feed i.e. 4.8017 Kg and showed poorest feed conversion ratio i.eo 2.84 as compared to the birds of rest of three groups, i.e. B, C and D. The birds of Group B gained less weight i.e. 1.7343 Kg, consumed more feed i.e. 4.7983 Kg and showed poorer feed conversion ratio i.e. 2.77 than the birds of Group C and D. The birds of Group C gained less weight, i.e. 1.8293 Kg consumed more feed i.e. 4.6733 Kg and showed poor feed conversion ratio i.e. 2.55 when compared with the birds of Group D but showed better performance tha the birds of Group A and B. The birds of Group D gained significantly more weight (P<0.05) i.e. 1.8567 Kg, at low feed intake i.e. 4.6510 Kg and showed significantly better feed conversion ratio (P<0.05) i.e. 2.50 as compared to the birds of Group A and B, as the light intensity (wattage) available to the birds of Group D was very low, hence there was less activity due to less movement, as compared to Group A,B and C. Therefore, the birds of Group D converted more available energy into weight gain and showed best performance as compared to other three groups i.e. A, B and C.
Dressing percentage recorded after 8th week of age was 61.85% 62.24% 62.86% and 63.11% for Group A, B, C and D respectively. A non-significant difference was observed among all the groups.
There was no mortality throughout the experimental period and apparently no considerable abnormality was observed.

Publisher: 1989Dissertation note: The present project was planned to study the effect of egg weight on chick weight at day old and its subsequent performance in Japanese quails.
Three hundred and sixty quail eggs were purchased from a local breeding farm and divided into 3 equal groups i.e., A, B and C according to their weights i.e. , small (8.5-9.5 gm), medium (9.6-10.5 gm) and large (10.6-11.5 gm) respectively. The eggs were incubated and hatched.
Sixty chicks from each group were randomly divided into 3 replicates of 20 chicks each and were reared under the identical management and environmental conditions. A commercial quail's ration was provided ad libtium. Fresh and clean water was given all the times.
The experimental chicks were weighed individually at one day-old and on weekly basis upto the age of 6 weeks. Weekly feed consumption was also recorded for each group. At 6 weeks of age two birds from each replicate were picked up randomly and slaughtered to observe the dressing percentage of visceral organs and biochemical values of blood. The average weight gain observed per quail upto 6 weeks of age on the basis of egg weight in groups A, B and C was 119.70, 130.70 and 147.30 gms and the average feed consumption per quail was 472.83, 481.89 and 463.88 gms respectively. The feed efficiency values were 3.95, 3.68 and 3.14 respectively. The mortality percentage was 5.00, 3.33 and 0 percent.
The average dressing percentage was 60.64, 67.88 and 64.23 respectively. The average weight of liver was apparently more in quails hatched from group B as compared to quails hatched from group A and C. The quails hatched from group B exhibited apparently maximum weight of heart as compared to quails hatched from group A and C. However, the average weight of gizzard was maximum in quails hatched from group C as compared to quails hatched from group A and B.
Statistical analysis of the data revealed non-significant effect of egg weight on feed consumption, dressing percentage, giblet weight (liver, heart and gizzard), protein, lipids and cholesterol of serum, packed cell volume, total leucocytic count, erythrocyte sedimentation rate, hemoglobin and erythrocytes. However, the effect of egg size was highly significant at (P 0.1) in case of body weight gain, feed efficiency and blood sugar level of experimental quails. The monetary return per quail was Rs. 2.00.
