鱼源发酵饲料蛋白对生猪生长性能和肉品质的影响

Effect of fish source fermented feed protein on growth performance and meat quality of pigs

试验旨在研究鱼源发酵饲料蛋白对猪生长性能和肉品质的影响。选取120头日龄相近、健康、体重(17.8±0.2)kg的仔猪随机分为4组,每组3个重复,每个重复10头猪。对照组猪饲喂常规全价饲料。试验组1、组2、组3保育期猪试验1~30 d分别饲喂添加10%、15%、20%的鱼源发酵饲料蛋白的饲料,试验31~180 d分别饲喂添加15%、20%、25%的鱼源发酵饲料蛋白的饲料。结果显示,与对照组相比,试验组体增重均高于对照组,试验组猪的疾病发生情况明显低于对照组。试验组1猪肉中呈味氨基酸种类多于对照组。研究表明,使用鱼源发酵饲料蛋白可有效提高猪的生长性能和肉品质,添加15%~20%鱼源发酵饲料蛋白效果较好。

The experiment was conducted to study the effect of fish source fermented feed protein on the growth performance and meat quality of pigs.A total of 120 healthy and active piglets of similar age,with the same body weight of(17.8±0.2)kg,were randomly divided into four groups,with three replicates in each group and 10 pigs in each replicate.Pigs in the control group were fed a conventional full-value diet.Pigs in the experimental group 1,group 2 and group 3 during the conservation period were fed diets supplemented with 10%,15%and 20%fish source fermented feed protein from 1 to 30 d,and fed the diets supplemented with 15%,20%and 25%fish source fermented feed protein from 31 to 180 d,respectively.The results showed that compared with the control group,the body weight gain of the experimental groups was higher than that of the control group,and the disease occurrence of the experimental groups'pigs was significantly lower than that of the control group.The types of flavorful amino acids in the pork muscle of the group 1 were higher than those in the control group.The experiment indicates that the use of fish source fermented feed protein can effectively improve the growth performance and pork quality of pigs,and the effect of adding 15%~20%fish source fermented feed protein is better.
