本试验旨在探究高直链淀粉玉米(简称高直玉米)替代普通玉米对于断奶羔羊生长性能、营养物质消化率和血液生理生化指标的影响。将27头平均体重为(8.97±0.19) kg的湘东黑山羊随机分为3组,每组4头公羊、5头母羊,试验羊单栏饲养。3组羔羊分别饲喂用高直玉米替代基础饲粮中0(A组,作为对照组) 、50%(B组) 、100%(C组)普通玉米的试验饲粮。预试期7 d,正试期28 d。结果表明:与对照组相比,B、C组羔羊的平均日增重显著增加(P < 0.05),干物质、粗蛋白质、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)表观消化率显著提高(P0.05);C组羔羊血清VEGF和LAC含量显著高于对照组(P

This experiment was conducted to study the effects of normal corn replacement by high amylose corn on growth performance, nutrient apparent digestibility and blood biochemical and physiological indexes of weaning goats. Twenty-seven Xiangdong black goats with an average body weight of (8.97±0.19) kg were divided into 3 groups with 4 male goats and 5 female goats and each of them was raised in a single column. The weaning goats in the 3 groups were fed experimental diets, and the experimental diets were formulated by replacing 0 (A group, as co...
