Supplementation of bypass fat during early lactation in high yielding cross bred cows ensures good returns

The study was conducted to assess the efficacy of bypass fat supplementation for alleviating energy deficit in high yielding crossbred cows during the early lactation period. Twelve crossbred (Holstein Friesian * Local) cows in early stage of their second and third lactation (10–15 d of calving) with more than 10 l of daily milk production were dewormed and randomly assigned in two groups (Average milk production, 10.15 l and fat percentage 3.3%). The first group of cows (T1) was kept as control and was not supplemented with any energy supplements. The second group of cows (T2) was supplemented with commercial bypass fat at the rate of 10 g/l of milk produced per day during the initial 90 d of lactation. The final average milk yield of the bypass supplemented cows was 12.32 ± 0.49 which was significantly (P<0.05) higher than unsupplemented cows in control group (11.03 ± 0.26). Also, the average milk fat during the study period differed significantly (P<0.05) in the bypass supplemented group over the control group. Besides this, supplementation of bypass fat during early lactation ensured good return over feed cost to the farmers.
