Background: Conjugated linoleic acid (CLA) has been shown to influence a range of biological processes. The current study was aimed to evaluate the effect of CLA supplementation during prepartum on nutrient intake, milk production and milk production efficiency in crossbred cows during postpartum.
Methods: Multiparous crossbred cows (n=30) were allotted to three treatment groups: Control group (CG) was supplemented 50 g bypass fat top dressed on basal diet; CLA-25 group was supplemented with 25g CLA and 25 g bypass fat top dressed on basal diet; CLA-50 group was supplemented with 50g CLA top dressed on basal diet. Supplementation started -21d from calving and continued till 60 days in milk (DIM). The feed and residue samples were analysed for its chemical composition. Milk samples were analysed on weekly basis for its composition.
Result: Positive effect of CLA supplementation on milk parameters was observed where CLA supplemented cows had higher milk yield, protein yield, SNF yield and total milk solid yield. Milk fat depression (MFD) was observed in CLA supplemented cows. Milk production efficiency was higher in CLA supplemented cows.
