| description | This research was conducted to study the effects of rumen by pass protein-fat supplement on the performance and milk quality of dairy cow. Previous study indicated that protein capsulation effectively protects feed’s Polyunsaturated Fatty Acids (PUFA) from biohydrolysis and biohydrogenation in the rumen. A latin square research design 3 × 3 × 2 was adopted (3 cows, 3 treatments, and 2 replications). The treatments were inclusion of protected protein-fat supplement (T1), inclusion of unprotected protein-fat supplement (T2), and control (C). Effects of treatments on the cow’s performance were observed based on variables of nutrients intake, nutrients digestibility, and milk production. Effects on milk quality were determined by compositions of milk constituents and milk Fatty Acids (FA). Results showed that treatments have no significant effect on Dry Matter (DM) and nutrients intake, except for Extract Ether (EE) intake which was significantly different (p<0.05) between treatments respectively 0.460; 0.495; 0.372 kg/cow/day for T1, T2, and C. The treatments also had no significant effects on DM and nutrients digestibility. There were no significant effects of treatments observed in the variables of milk production and quality. Milk FA profiles showed protected protein-fat supplements tend to decrease the proportion of medium chain FA (C10:0-C14:0) (13.58% vs 14.75% for T1 and C) and increase the proportion of Oleic Acid (C18:1) (29.39% vs 26.21% for T1 and C). Although the effects on FA profiles were not significant, the study had indicated that inclusion of protected protein-fat supplement has positive effect to increase the value of milk FA. |
