摘要：

为了研究鲁梅克斯K-1对关中奶山羊产奶性能的影响。选取50只健康、体质量、产奶量接近(P>0.5)的关中奶山羊，试验共分5个处理，每个处理10只，各处理每只羊每天均饲喂3 kg粗饲料和1 kg精饲料，对照组粗饲料全喂玉米秸杆青贮，A、B、C、D组用鲁梅克斯青贮分别替代0.5、1、1.5、2 kg玉米秸杆青贮，进行为期50天泌乳试验。结果表明：（1）整个试验期，处理C组共产羊奶1850 kg，处理C组分别比CK、A、B、D组多产奶490、325、260、310 kg，差异极显著(P<0.01)；（2）处理C组比CK、A、B、D组奶山羊的乳干物质、乳脂率、乳蛋白及乳糖含量均有所改善，但差异不显著(P>0.5)；（3）C组的纯收入为5675元，C组分别比CK、A、B、D组多收入2035、1350、1065、1215元，差异极显著(P<0.01)。鲁梅克斯营养丰富，与玉米秸杆混合青贮能有效提高关中奶山羊产奶量，改善乳蛋白、乳糖及乳脂率，其在粗饲料中添加量在50%为宜。

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.
