摘要
6窝74头荣昌纯种哺乳仔猪,以窝为单位随机分为两组,20—60日龄分别饲喂同配方、不同加工处理(制粒、膨化)的两种日粮,测定乳猪的增重、料耗、鲜粪中大肠杆菌数、乳猪腹泻发生率等指标。结果表明:膨化饲料提高了饲料进食量2.56％(P>0.05)、日增重18.30％(P<0.01),改善了饲料报酬13.39％(P<0.05);鲜粪中大肠杆菌数:20日龄无显著差异(P>0.05),60日龄时膨化料组较制粒组降低43.90％(P<0.01);制粒腹泻发生78头次,而膨化组发生17头次。
Seventy-four suckings from 6 litters of Rongchang purebed sows were divided at random with a whole litter as a unit into 2 groups and each consisted of 3 litters. The test began at 20-day and ended at 60-day of age. During the test period all the suckings were fed on the same formulation of feedstuff, only with the difference in processing methods (extruded or pelletized). And each treatment was reported 3 times. Measurements were carried out as follows. darily gains, feed consumptions, E. coli in fresh faces, and the incidences of diarrhea. The results signified that extruded feedstuff improved intake by 2. 56% (P>0. 05), increased daily gains by 18. 30% (P<0. 01), enhenced feed conversion efficiency by 13. 39% (P<0. 05). Results also showed that the population of E. coli for the extruded feedstuff group were 43.9% (P<0. 01) lowered than that for the pelletized group while there were no differences (P>0. 05) at 20-day old. Furthermore, diarrhea incidences were 78 for the pelletized, highly significantly higher than that for the extruded (17) during the stage of 20 -60 days of age.
