【摘要】：本试验旨在研究发酵蚕蛹豆粕粉替换鱼粉对断奶仔猪生长性能、血清生化指标及器官指数的影响,及确定其适宜的替换水平。选用120头(28±1)日龄断奶、初始体重为(7.64±0.67)kg的健康"杜×长×大"三元杂交仔猪,分为4组,每组3个重复,每个重复10头猪。对照组饲喂基础饲粮,3个试验组分别用发酵蚕蛹豆粕粉替换基础饲粮中25%、50%、100%的鱼粉。预试期3 d,正试期21 d。结果表明:1)各组试验全期平均日增重、平均日采食量(ADFI)、料重比均差异不显著(P0.05),但对照组第1周ADFI显著高于25%替换组(P0.05),50%、100%替换组第2周ADFI显著高于25%替换组(P0.05)。2)25%替换组血清总胆固醇含量显著高于对照组(P0.05),25%替换组血清高密度脂蛋白胆固醇含量显著高于对照组和50%替换组(P0.05),25%替换组血清载脂蛋白B含量显著高于50%替换组(P0.05),对照组血清总蛋白含量显著高于50%替换组和100%替换组(P0.05)。3)各组腹泻率、器官指数、血清免疫球蛋白含量均差异不显著(P0.05)。综合各项指标,发酵蚕蛹豆粕粉可替代饲粮中25%的鱼粉,而不影响断奶仔猪的生长性能。
[Abstract]:The purpose of this experiment was to study the effects of silkworm pupa meal replacement on growth performance, serum biochemical index and organ index of weaned piglets, and to determine the appropriate replacement level. A total of 120 (28 卤1) day weaned healthy "du 脳 long 脳 large" three-way crossbred piglets with an initial body weight of (7.64 卤0.67) kg were divided into 4 groups, with 3 replicates in each group and 10 pigs per replica. The control group was fed with basic diet, and the three groups were fed with fermented silkworm pupa soybean meal to replace 25% fish meal in the basic diet. The pretest period was 3 days and the positive test period was 21 days. The results showed that: 1) the average daily gain (ADG) and average daily feed intake (ADFI),) of each group were not significantly different (P0.05), but the ADFI of the control group was significantly higher than that of the 25% replacement group (P0.05) at the first week, and the ADFI of the control group was significantly higher than that of the 25% replacement group (P0.05). In the second week of 100% replacement group, ADFI was significantly higher than that in 25% replacement group (P0.05). The serum total cholesterol content in the 25% replacement group was significantly higher than that in the control group (P0.05). The content of HDL-C in 25% replacement group was significantly higher than that in control group and 50% replacement group (P0.05), and the serum apolipoprotein B content in 25% replacement group was significantly higher than that in 50% replacement group (P0.05). The serum total protein content of control group was significantly higher than that of 50% replacement group and 100% replacement group (P0.05). There was no significant difference in diarrhea rate, organ index and serum immunoglobulin content in each group (P0.05). The results showed that fermented silkworm pupa soybean meal could replace 25% fish meal without affecting the growth performance of weaned piglets.
