【摘要】 用杂种育肥仔猪24头,随机分成3组,每组8头。前期饲粮中添加花生秧粉的比例分别为10%,15%和30%;后期依次为30%,40%和60%,全期采食计量不限量。试验结果表明,1,2,3组平均日增重分别为438.78g,415.56g和245.79g。每kg增重消耗饲料分别为5.67kg,6.23kg和9.07kg。饲粮中添加过量花生秧粉会明显降低育肥猪的增重速度和饲料转化效率,经济效益下降。以前期小超过10%,后期不超过30%为佳。更多还原

【Abstract】 24 hybrid hogs were evenly divided into three groups at random, namely Group One, Group Two and Group Three. Peanwt vine powder in each group diet was 10% , 15% and 30% respectively in early testing stage, and 30%, 40% and 60% respectively in late stage. Feed consumption was measured and hogs were fed to appetite. The average daily weight gain of hogs in each group was 438.78g, 415.56g and 245.79g respectively, and the feed consumption for 1 kg of weight gain was 5.67kg, 6.23kg and 9.07kg respectivey. The result shows that adding too much peanut vine powder to hog diet would significantly lower the weight gain speed, feed conversion rate and the net profit. Therefore farmers in the main peanut producing areas of Henan Province should promptly change their feeding patterns, where they use peanut vine as their main hog diet. Peanut vine in hog diet should not be more than 10% in early feeding stage, not be more than 30% and in late stage.更多还原
