Effect of Prilled Fat Supplementation on Milk Production Performance of Crossbred Cows

A study was undertaken to assess the effect of prilled fat supplementation on certain plasma metabolites and milk production in Karan Fries cows. Ten cows were selected from Livestock Research Centre and divided into two groups of 5 animals each. The animals in control group were fed as per requirements while treatment group also received prilled fat @ 75 g/cow/day in addition to control from 45 days prepartum till parturition. After parturition the treatment group received prilled fat @ 150g/cow/day till day 70^th of lactation. Body condition score of treatment cows was more (P<0.05) in comparison to control group. The concentration of plasma NEFA (P<0.01) and total cholesterol was lower (P<0.05) in treated cows than the control group. Cows in treatment group produced more milk with higher fat and SNF contents (P<0.01). Milk cholesterol concentration was less (P<0.01) in animals of the treatment group. The feeding of prilled fat was economical resulting in an additional income generation of 94.46/cow/day.
