| 摘 要： | 试验采用不同添加比例的百合渣替代部分玉米,以确定百合渣在“杜×长×大”三元杂交断奶仔猪日粮中的适宜添加比例。选择体重健康状况良好的“杜×长×大”三元杂交（20.14±0.78）kg的断奶仔猪36头随机分为4组,每组3个重复,每个重复3头猪。用百合渣分别替代饲粮中0（对照组）、5.00%（试验Ⅰ组）、10.00%（试验Ⅱ组）、15.00%（试验Ⅲ组）的玉米。试验预试期7 d,正试期30 d,试验结束后测定断奶仔猪生产性能。结果表明：各组间初始体重差异不显著（P>0.05）,试验结束时试验Ⅰ组、Ⅱ组和对照组平均体重分别为42.08、38.42和39.39 kg,分别比Ⅲ组高6.67、3.01和3.98 kg;对照组和试验Ⅰ组平均日增重均显著高于Ⅱ组和Ⅲ组（P<0.05）,平均日增重分别为646.47 g/d和728.24 g/d;Ⅲ组采食量显著低于对照组和Ⅰ组（P<0.05）,其他组之间差异不显著;在料重比方面,Ⅰ组显著低于对照组、Ⅱ组和Ⅲ组（P<0.05）;腹泻率方面,由于对照组和试验Ⅰ组仅各有1头仔猪出现腹泻,经治疗后即痊愈,试验Ⅱ组和Ⅲ组未出现腹泻情况,各组均未出现死亡仔猪。

| Abstract: | The aims of the present study were to assess the effects of dietary replacing corn with Lilium brownii residue on production performance of three-way crossbred(′Duroc×Landrace×Yorkshire′)weaned piglets,and to determine its proper addition ratio in the diet.A total of 36(′Duroc×Landrace×Yorkshire′)three-way crossbred weaned piglets weighed(20.14±0.78)kg with good health status were selected and randomly divided into 4 groups with 3 replicates in each group and 3 piglets in each replicate.Lilium brownii residue were used to replace 0(control group),5.00%(experimental groupⅠ),10.00%(experimental groupⅡ),and 15.00%(experimental groupⅢ)of corn in the diet.The pre-experiment period was 7 d and the formal trial period was 30 d.After the experiment,the production performance of the weaned piglets was measured.The results showed that there was no significant difference in the initial weight between the four groups(P>0.05).At the end of the experiment,the average weights of the experimental groupⅠ,experimental groupⅡand control group were 42.08,38.42 and 39.39 kg,respectively,which were 6.67,3.01 and 3.98 kg higher than that of the experimental groupⅢ,respectively.The average daily weight gain of the control group and experimental groupⅠwas 646.47 and 728.24 g/d,respectively,and both of them was significantly(P<0.05)higher than that of the experimental groupⅡandⅢ.The feed intake of the experimental groupⅢwas significantly(P<0.05)lower than that of the control group and experimental groupⅠ,while no significant difference between the other groups was observed(P>0.05).In terms of the feed to gain ratio,the experimental groupⅠwas significantly(P<0.05)lower than that of the other three groups.The control group and experimental groupⅠseparately had only one piglet developed diarrhea and both of them were healed after treatment.There was no diarrhea in the experimental groupⅡandⅢ.No piglets died in each group. |
