摘要

本试验将鱼粉、血浆蛋白粉、酵母粉、肠膜蛋白粉按一定比例组合添加到饲粮中，旨在对比研究不同蛋白质源组合对保育猪生长性能及血清生化指标的影响。选用初始体重为（6.36±0.20）kg的"杜×长×大"三元杂交保育猪108头，随机分为3组，每组6个重复，每个重复6头猪。3组保育猪分别饲喂含1.5%血浆蛋白粉+2.0%鱼粉（A组，作为对照组）、3.0%肠膜蛋白粉+5.0%鱼粉（B组）、2.0%酵母粉+2.0%肠膜蛋白粉+2.0%鱼粉（C组）的饲粮，预试期3 d，正试期14 d。结果表明：1）B组的平均日采食量和平均日增重均显著低于A和C组（P<0.05），与A组相比，C组的平均日采食量和平均日增重分别提高1.76%和8.13%，但差异不显著（P>0.05）；在料重比方面，B和C组与A组相比差异均不显著（P>0.05），但C组显著低于B组（P<0.05）。2）血清总蛋白、白蛋白、球蛋白、尿素氮含量与白球比以及谷丙转氨酶和谷草转氨酶活性3组间无显著差异（P>0.05）。3）与A组相比，B组钱重比增加13.47%（P>0.05），C组钱重比降低5.22%（P>0.05）。由此可见，2.0%酵母粉+2.0%肠膜蛋白粉+2.0%鱼粉组合在提高保育猪生长性能、经济效益方面效果最好，1.5%血浆蛋白粉+2.0%鱼粉组合效果次之，而3.0%肠膜蛋白粉+5.0%鱼粉组合相比之下效果较差。

Abstract

In this experiment, fish meal, spray-dried plasma protein (SDPP), yeast extract (YE) and dried porcine solubles (DPS) were added into a diet according to a certain proportion, in order to compare the effects of different protein source combinations on growth performance and serum biochemical indices of nursery piglets. A total of 108 nursery piglets with the initial body weight of (6.36±0.20) kg were randomly divided into three groups, each group had six replicates and each replicate had 6 piglets. Piglets in group A (control group) were fed a diet containing 1.5% SDPP+2.0% fish meal, piglets in groups B and C were fed the diets containing 3.0% DPS+5.0% fish meal and 2.0% YE+2.0% DPS+2.0% fish meal, respectively. The experiment comprised 3 d-adaptation and 14 d-test. The results showed as follows:1) the average daily feed intake and average daily gain in the group B were significantly lower than those in the groups A and C (P<0.05). The group C compared with the group A, the average daily feed intake and average daily gain were increased by 1.76% and 8.13%, but the differences were not significant (P>0.05). Feed/gain in the groups B and C had no significant difference compared with the group A (P>0.05), but it in group C was significantly lower than that in group B (P<0.05). 2) The contents of total protein, albumin, globulin and urea nitrogen, albumin/globulin, and the activities of alanine transaminase and aspartate transaminase in serum had no significant differences among three groups (P>0.05). 3) Compared with the group A, the money/gain increased by 13.47% in the group B (P>0.05), and decreased by 5.22% in the group C (P>0.05). It is concluded that the combination of 2.0% YE+2.0% DPS+2.0% fish meal has a best effect for improving the nursery piglets' growth performance and economic benefits, the combination of 1.5% SDPP+2.0% fish meal is the second, and the combination of 3.0% DPS+5.0% fish meal has a worse effect.
