Abstract

Thirty lactating buffaloes were divided into three groups (10 animals each), first group; fed on unsupplemented control ration (CG), second group (G2) fed on ration supplemented with (600gm Alpha Mega-fat powder/head/day)and third group (G3) fed on ration supplemented with (600gm soybean oil /head/day). The obtained results revealed that there are significant (p < 0.05) increase in milk yield, Fat corrected milk (FCM) , total solids and fat contents as compared with control group.It was also noticed that supplementing rations with Alpha Mega-fat (G2) per buffalo daily improved the fatty acids (C18 "Stearic acid", C18:1 "Oleic acid" and C20 "Arachinic acid") significantly (p < 0.05), whereas, unsupplementing rations with control (CG) increased the fatty acids (C12 "lauric acid" and C14 "myristic acid") significantly (p < 0.05), when compared with the corresponding groups.Addition of both Alpha Mega-fat and soybean oil to ration of dairy buffaloes improved production efficiency ((kg7%FCM/1kg SVP for milk) and Feed conversion (kg 7%FCM/1kg SVP for milk) significantly (p < 0.05). The results of the present study suggested on economic basis that, supplementation of Alpha Mega-fat to lactating Buffaloes generated a fourfold return on investment through a 15.26 % improvement in production efficiency, feed conversion and milk yields in 70 days trial.
