| Dissertation note | Buffaloes contributed 61.1 percent to the total milk of Pakistan, which is world’s 4th largest milk producing country. Protein requirements of buffalo appear to differ from those of cattle, yet information on these nutritional requirements is limited. But establishing the protein and energy requirements for animals is key point to lead the nutritionists for the optimum supply of these nutrients. Thus, understanding the protein and N efficiency and an estimation of optimum protein supply to buffalo is the need of time in terms of economics and animal production. This study was conducted at “Dairy Animals Training and Research Center, University of Veterinary and Animal Sciences, Ravi Campus, Pattoki” to check the performance of buffaloes in response to increasing levels of dietary crude protein (CP) supplies (9.3, 10.0 and 11.5% of DM). Design of the experiment was 3×3 Latin Square with two animals in each treatment, and total duration of the study was 119 days. Different parameters were determined by using different but recommended laboratory techniques. Milk parameters include milk yield, milk protein, fat, lactose and density. Blood parameters include BUN, TG, NEFA and glucose. Fecal and urine sampling and tests were performed using standard procedures to estimate the N efficiency and N balance. Data was analyzed using GLM procedures of SAS. DMI was similar among all the treatments with an average value of 14.36 kg/d. Milk production increased from 7.75 to 8.04 kg/d in response to increase in dietary CP. Milk protein contents increased from 3.86 to 3.92%, milk fat contents from 6.12 to 6.44 % and 4% fat corrected milk from 10.05 to 10.92 kg/d, but milk lactose and milk density showed no response to increase in dietary CP from 9.3 to 11.5% of DM. However, milk lactose yield increased, but body weight of the animals decreased from 586 to 565 kg. Milk N efficiency also decreased from 21.9 to 18.7%, SUMMARY 44 but an increase in N intake observed with higher CP levels. Feed efficiency also increased from 0.54 to 0.56. Blood metabolites showed a positive response to increase in dietary CP. Glucose, BUN and NEFA increased with increase in protein supplies. While, TG contents were not affected by the treatments. Milk N excreted as gram per day increased but decreased as percent of N intake, resulting in reduced N efficiency. Urinary and fecal N excretion as gram per day also showed a slight linear increase. Retention of N remained unaffected by the treatments but the values are higher than that of cow, still a point reported to be attached with genetics of buffalo to retain more N in the form of BUN as its reserves. Increasing CP supplies improved both of the milk quantity and quality, and resulted in increased BUN, glucose, NEFA and N intake, but decreased N efficiency. In this sense, when buffalo is compared with cow, cow utilizes its dietary N in better way than buffalo. But when we estimate lactation performance of both, at different low and high levels of protein supplies, buffalo performs better at low level of dietary CP as compared to high protein diet. Current experiment served as opportunity to recommend the minimum level of dietary CP for buffaloes without effecting the animal production to minimize the cost and environment wastage. CONCLUSIONS In conclusion, increase in dietary protein supply results in improved quantity and quality of milk, but meanwhile this increased supply causes a decrease in nitrogen use efficiency, because protein supply above the required level starts to be excreted in urine and feces. And 11.5% CP of ration DM is sufficient for Nili-Ravi buffalo at this production status. |
