Abstract:

In this study the milk performance was tested from Guanzhong dairy goat fed with Rumex K-1 Fifty healthy Guanzhong dairy goats with a similar index on body weight and milk production (P>0.5) were randomly divided into five groups, 10 goats per group. Each of experimental group was fed coarse fodder (3 kg/d) with concentrated feed (1 kg/d), respectively. The goats in normal control group was fed silage maize straw as coarse fodder, and other A, B, C, D groups were fed silage maize straw combined with Rumex K-1with four dosage of 0.5, 1, 1.5, 2 kg, respectively for 50 days. Results showed that: (1) Goats in C group had a more milk production which totally produced 1850 kg milk during experimental time. Compared to the C group, the milk production had a significant decrease by about 490, 325, 260, 310 kg for CK, A, B and D (P<0.01). (2) Goats in C group had a better improvement on the content of milk solids, butter-fat content, lactoprotein and lactose (P>0.5). (3) Net income of goats in C group was 5675￥, which was reduced by about 2035￥, 1350￥, 1065￥ and 1215￥ for CK, A, B and D (P<0.01). These results suggested that Rumex K-1 was full of nutriments, silage maize straw containing with Rumex K-1 had a good effect on milk production, lactoprotein, lactose and butterfat content in Guanzhong goats, and the suitable volume of addition was half of coarse fodder.
