| Abstract | ||
| Eighteen indigenous buffalo bulls of about 295±7.31 Kg body weight and one year of age were randomly allotted into three similar groups. A calcium salt of fatty acids (Ca-SFA) was added to concentrate diet on DM basis of total concentrate as replacement of 25% and 50% of corn grain on energy basis. The first group (control) received a ration without supplementation (R1), the 2nd received ration supplemented with Ca-SFA instead of 25% of corn grain (R2) and the 3rd received a ration supplemented with Ca-SFA instead of 50 % of corn grain (R3). The three rations were comparable in nutrient contents. The content of ash, fatty acids (FA) and acid ether extract (AEE) were higher in R2 and R3 compared to the control ration. Feeding Ca-SFA did not influence on dry matter intake (DMI), average daily gain (ADG), feed conversion and weight gain of supplemented rations. Nutrient digestibility, except AEE and DE, were not affected with Ca-SFA supplementation to the experimental rations. The digestibilities of cell wall constituent (NDF, ADF, cellulose and hemi-cellulose) were not significantly affected by added Ca-SFA compared with control group. Also, the nutritive values of the experimental rations were lacked any significance. Rumen activity as pH, TVFA’s, NH3–N and microbial protein synthesis were not affected by feeding Ca-SFA as compared to the control group. Total cholesterol and free fatty acids (FFA’s) in blood serum of bulls were significantly higher (P<0.05) in the treated groups compared to the control group. Ca-SFA supplementation was not affected on the values of total lipids and glucose in blood serum. It could be concluded that replacement of Ca-SFA instead of 25% up to 50 % the energy of yellow corn could be efficiently utilized in finishing rations of buffalo bulls as by pass-protected fat. | ||
