【摘要】 研究了膨化大豆对 2 8日龄断奶仔猪生产性能和腹泻的影响 ,结果表明 :膨化大豆饲喂仔猪可提高第 2周以后的平均日增重 ;缩短仔猪腹泻时间、降低仔猪腹泻率 (P <0 0 1 ) ;降低皮褶厚度 (P <0 0 1 ) ;提高营养物质的表观消化率 ,其中粗蛋白、粗脂肪、干物质、粗灰分、有机物分别提高 1 8 91 % (P <0 0 1 )、 1 8 75 % (P <0 0 5 )、 1 1 0 3% (P <0 0 1 )、1 5 3 81 %和 9 71 % (P <0 0 5 ) ;降低仔猪的增重成本 ,2 8d仔猪可节约成本 0 48元 /头。更多还原

【Abstract】 The effect of the extruded soybean on the growth and diarrhea of weaned piglets was studied in this paper.The results showed that:pigs fed extruded soybean had greater average daily gain (ADG) after the second week (P<0.05) and during the whole period (P<0.05);had shorter diarrhea period and lower diarrhea rate (P<0.01);had a decreased skin-fold thickness(P<0.01).Pigs fed on soybean diet had higher apparent digestibility of crude protein (P<0.01),crude ash (P<0.05) and organic matter (P<0.05).It also could decrease the cost of gaining weight,each decreased 0.48 yuan during the 28 days assay.更多还原
