Productive Performance of Nili-Ravi Buffaloes by the Supplementation of Bypass Fat

The research project was conducted at the Livestock Experiment Station (LES), University of Agriculture Faisalabad to evaluate the effect of bypass fat supplementation on milk yield, milk composition and change in body weight in Nili-Ravi buffaloes. 12 animals of same parity, milk production and body weight were selected and randomly allotted to 4 treatments (bypass fat supplementation) viz., T 0 (control), T 1 (250g) , T 2 (350 g) and T 3 (450 g) in such a way that each treatment was comprised of 03 animals. The daily milk yield for seven weeks animal -1 was recorded. Milk composition and weight gain records were maintained on weekly basis. The statistical analysis showed significant (p<0.05) differences in milk yield. The highest production (9.44±0.62 Kg) was found in T 2 and the lowest (6.88±0.62 Kg) in control group. Whilst T 1 and T 2 were non-significant (p<0.05). Fat % differed significantly (p<0.05) in all treatments. The highest (6.9±0.09) was in T 3 and animals in T 0 yielded minimum fat% (6.19±0.09). T 1 and T 2 differed non-significantly (p<0.05). The protein, TS and SNF % did not differ in any treatment. Body weight gain and milk cost (/Kg) did not differ significantly. The supplementation increased milk yield and fat % in all treatments.
