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3kg粗饲料和1kg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、2kg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1850kg,处理C组分别比CK、A、B、D组多产奶490、325、260、310kg,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。
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-lwith 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〈O.O1）. （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.
