新型环保饲料对肥猪增重及日粮消化率的影响

Effects of new environmental protection feed on the weight gain and the rate of digestion of daily ration of pig

以水飞蓟残渣和果寡糖为主要饲料成分,研究其对猪增重和饲料利用率的影响,结果表明:在增重方面,试验组与抗生素组没有明显差异,试验组对粗蛋白、粗纤维、钙、磷的消化率在生长阶段比对照组分别高8.07%,19.85%,8.02%,5.21%(P<0.05),在育肥阶段,比对照组分别高4.64%,16.40%,7.38%,13.02%(P<0.05),2个阶段对粗脂肪的消化率无明显差异.

The effects of Holy Thistle and FOS on the production performance and feeds conversion ratio were studied. The result indicated that the test group and control group did not have obvious difference on weight gain;on the rate of digestion of crude protein, crude fiber, Calcium and phosphor during growing days, the test group was 8.07 %, 19.85 %, 8.02 %, 5.21% higher than the control group （ P 〈 0. 05）, during growing-finishing days, there were 4. 64%, 16.40% ,7.38%, 13.02% （ P 〈 0.05）than control group,the rate of digestion of crude fat during two stages had no obvious differences.
