摘要

本试验旨在研究采食量对沙漠雄鹿干物质采食量、营养物质消化率和生产性能的影响。选取12只4 ~ 5岁平均体重11 + 0.250 kg的沙漠山羊,随机分为3组。第一组采食木犀草饲料,第二组采食无木犀草的天然草场,第三组采食花生秸秆。观察第一组致死腹泻病例后,改采50%天然牧草+ 50%白乳牛饲料的喂养方式。对饲料进行了体外消化率分析。试验设计采用随机化设计,数据分析采用方差分析,均数差异检验采用最小显著性差异检验。结果表明,单独饲喂白羊草可导致雄鹿致死性腹泻,但不影响食欲,白羊草的干物质消化率和体外有机物消化率显著(P<0.05)高于花生秸秆和自然放牧。花生秸秆和自然放牧组的增重显著高于单独放牧组(P<0.05),但当植物生物量的50%被自然放牧取代时,增重显著高于单独放牧组(P<0.05)。综上所述,育成期采食量为优质粗饲料。

Effects of Alysacrpus Monilifer fodder intake on feed consumption and performance of desert goats
This study was conducted to study the effects of the intake of the Alysacrpus Monilifera on dry matter intake, digestibility of nutrients and performance of Desert bucks. Twelve Desert goats bucks 4-5 years old with an average weight of 11 + 0.250 kg, were divided into three equal groups. The first group was fed A. Monilifera fodder, while the second group consumed the natural pasture free of A. Monilifera while the third group consumed the groundnut haulms. After observing the cases of deadly diarrhea in the first group, the feeding pattern was modified with 50% natural pasture and 50% A. Monilifer fodder. The fodder was analyzed as well as conducting in vitro digestibility. The experimental design was randomized and the data were analyzed using the analysis of variance and the detection of differences among means using least significant difference test. The results showed that feeding A. Monilifer alone resulted in fatal diarrhea in bucks without affecting appetite, and the dry matter digestibility and organic matter in vitro digestibility was significantly (P<0.05) higher in A. Monilifer than compared to the groundnut haulms or the natural grazing. The weight gain was significantly (P<0.05) higher for the group on groundnut haulms and the natural grazing than those on A. Monilifer alone but when 50% of the plant biomass was replaced by the natural grazing the gain was significantly higher. The study concluded that the intake of A. Monilifer at the growth stage was good quality roughage when fed as part of the diet.
