【摘要】：本试验旨在研究大豆皮替代饲粮中稻草对波杂山羊生长性能、营养成分表观消化率和血液生化指标的影响。选取28只体重为(18.51±0.47)kg的健康波杂公山羊,采用完全随机化设计分为4个试验组,每组7只,每个试验组饲粮中大豆皮替代稻草的水平分别为0%、33%、67%、100%。预试期7 d,正试期49 d。结果表明:试验前期0~15 d、后期31~45 d和全期平均日采食量差异极显著(P0.01),其中33%替代组最高,100%替代组最低;耗料增重比随大豆皮替代饲料中稻草水平的提高显著降低(P=0.020),其中67%替代组耗料增重比最低;0~45 d,干物质、总能、中性洗涤纤维和酸性洗涤纤维的表观消化率差异极显著(P0.01),并且67%替代组中各营养成分消化率最高;粗蛋白消化率的组间差异不显著(P0.05);育肥羊血液生化指标均在正常值范围内,各试验组之间的差异均不显著(P0.05)。综上所述,大豆皮替代饲粮中33%和67%稻草可以提高波杂山羊的生长性能和营养成分表观消化率,并且对血液生化指标没有负面影响。
[Abstract]:The purpose of this experiment was to study the effects of rice straw on growth performance, apparent digestibility and blood biochemical index of Boza goats. 28 healthy Boza male goats with weight of 18.51 卤0.47)kg were divided into 4 groups, 7 in each group, by a completely randomized design. The level of replacing rice straw with soybean skin in diet of each trial group was 0 ~ 33336767 and 100, respectively. The pretest period was 7 days and the current test period was 49 days. The results showed that there were significant differences in the average daily feed intake between 0 ~ 15 days, 31 ~ 45 days and the whole period in the early stage of the experiment, among which 33% substitution group was the highest and 100% substitution group was the lowest. With the increase of rice straw level in soybean husk substitute feed, the ratio of feed consumption to weight gain decreased significantly with the increase of rice straw level in soybean husk, and the weight gain ratio of 67% substitution group was the lowest at 0 ~ 45 days, dry matter, total energy, dry matter, total energy, The apparent digestibility of neutral detergent fiber and acid detergent fiber was significantly different, and the digestibility of nutrition components was the highest in 67% substitute group, the difference of crude protein digestibility between groups was not significant (P 0.05), and the biochemical indexes of blood of fattening sheep were within the normal range. There was no significant difference between the two groups (P 0.05). In conclusion, 33% and 67% straw in diet replaced by soybean skin could improve the growth performance and apparent digestibility of nutritional components of Boza goats, and had no negative effect on blood biochemical indexes.
