Abstract

Two experiments were conducted to study the effects of rumen-protected Met (RPM) alone or with rumen-protected Lys (RPL) on milk yield and plasma amino acids of dairy cows. In experiment 1, 24 multiparous Holstein cows (154 DIM) were assigned to one of 3 groups where each cow received 0 g/d of RPM and RPL (C), 30 g/d of RPM (M), or 30 g/d of RPM plus 25 g of RPL (ML). The study lasted for 8 weeks where milk yield and composition were determined weekly. Daily milk yield averaged 28·0, 27·8, and 29·7 kg/cow for the C, M, and ML groups, respectively. Dietary treatments had no effects (P ≥ 0·54) on milk contents of fat, lactose, solid non-fat or total solids. Milk protein content in the ML group was greater (P < 0·05) than the C and M groups. Plasma levels of all AA were not significantly (P ≥ 0·09) affected by supplemental RPL and/or RPM. In experiment 2, 30 multiparous Holstein cows (100 DIM) were assigned to one of 3 groups where each cow received 0 g/d of RPM and RPL (C), 50 g/d of RPM (M), or 50 g/d of RPM plus 25 g/d of RPL (ML). The study lasted for 5 weeks. Cows in the M (30·5 kg) and ML (31·4 kg) groups produced (P < 0·05) more milk than those of the C group (29·1 kg). Under conditions of this study, RPM plus RPL improved milk yield and protein contents of dairy cows and was better than supplying RPM alone. Response in milk yield to RPM and RPL was affected by the MP status of cows which deserves further investigation.
