Influence of receiving different levels of dietary fat on the performance of finishing steers

Eighteen crossbred Holstein finishing steers of 200±25kg weight and 9.5 to 10 months of age were assigned randomly to one of the three groups having 6 animals in each those were supplied with different rations at different levels of calcium long chain of fatty acids (Ca-LCFA) for 120 days and the growth, feed conversion efficiency, dry matter intake and blood profile was studied. The control group received 0% of Ca-LCFA, 1^st group 3% and the 2^nd group 6% of CLCFA.The average daily gains of control,1^st and, 2^nd groups were 1.083, 1.011 and 1.115kg, respectively and the fed conversion efficiency were 5.340, 5.688 and 5.898 which showed no significant difference treatment (P<0.05).Average daily dry matter intake of entire period in different groups were 7.433, 7.467 and 7.565 which was also not significant (p<0.05). The blood Hemoglobin, Glucose, PCV and total protein were also measured. The pcv of the 2^nd group was significantly (P<0.05) lower than the other group, and also total protein of control groups was slightly lower than the other two groups.
