Abstract

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., T⁰ (control), T¹ (250g) , T² (350 g) and T³ (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 T² and the lowest (6.88±0.62 Kg) in control group. Whilst T¹ and T² were non-significant (p<0.05). Fat % differed significantly (p<0.05) in all treatments. The highest (6.9±0.09) was in T³ and animals in T⁰ yielded minimum fat% (6.19±0.09). T¹ and T² 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.
