Abstract:
Two experiments were carried out to evaluate the effects of fibrolytic enzymes supplementation on in vitro degradation of sugar beet pulp and in vivo nutrients digestibility, milk yield and its composition by mild-lactating buffaloes. In the in vitro experiment, dry matter and organic matter disappearance (IVDMD and IVOMD) were determined for sugar beet pulp supplemented separately with laboratory produced fibrolytic enzymes (Asperozym) and commercial fibrolytic enzymes source (Tomoko®) at 3 levels (0, 1, 1.5 and 2 g kg-1 DM). Increasing the Asperozym and Tomoko® supplementation levels up to 2 g kg-1 DM exhibited the highest (p<0.05) values of IVDMD and IVOMD. In the in vivo experiment, fifteen mild-lactating buffaloes after 3 months of parturition were divided into three groups, five animals each, using complete random design. The first group was fed on 45% Concentrate Feed Mixture (CFM), 30% corn silage ,15% dried sugar beet pulp and 10% rice straw (control ration). The second group was fed control ration supplemented with Asperozym at 2 g kg-1 DM (R1), while the third group was fed control ration supplemented with Tomoko® at 2 g kg-1 DM. (R2). Asperozym and Tomoko® supplementation significantly (p<0.05) increased DM, OM, CF, NFE, NDF digestibility for treated groups compared with the control group, while blood plasma parameter , milk yield and its composition did not significantly (p<0.05) change among all groups.
