[Abstract]:The purpose of this study was to study the effects of different levels of perilla additive on the performance, lipid index and immune function of laying hens in order to provide a theoretical reference for their application in poultry production. In the feeding experiment, 360 indigenous laying hens with similar body weight at 28 weeks were randomly divided into 4 groups, 3 replicates in each group and 30 in each. The control group was treated with free drinking water. The 4 groups were fed with 3% of processed perilla seeds in the basal diet. The feeding experiment lasted 8 weeks (one week before feeding). The average fixed feed intake per chicken was 83.33 g / d, and the production performance indexes were calculated as follows: average daily egg production, egg laying rate, average egg weight, feed to egg ratio, qualified rate, egg specific gravity, eggshell strength, eggshell thickness, egg shape index. Determination of serum total cholesterol, triglyceride, high density lipoprotein, low density lipoprotein, egg yolk cholesterol, triglyceride of egg yolk; The related indexes of immune function were determined: total protein, titer of H5 avian influenza antibody, titer of H9 avian influenza antibody and Newcastle disease antibody titer. The results were as follows: the effect of perilla seed on production performance was as follows: adding perilla seed could improve the production performance of laying hens. The average daily egg production of the three groups was significantly higher than that of the other groups (P0.05), and the egg laying rate, average egg weight and egg qualified rate were significantly higher than those of the other groups. The egg quality of the experimental group was significantly higher than that of the control group (P0.05), the egg weight and eggshell strength of the three groups were significantly higher than that of the other groups (P0.05), but there was no significant difference in other indexes. However, with the increase of perilla seed supplementation level, all indexes showed an upward trend. 2 the effect of perilla seed on lipid index: there was no significant difference in lipid index between group 2 and control group in blood lipids, the indexes of lipid in group 3, group 4 and control group were higher than those in group 3 and group 4, respectively. There were significant differences (P0.05) in serum total cholesterol, triglyceride, high-density lipoprotein in the four groups were significantly higher than those in the control group (P0.05), and with the increase of perilla seed addition, there was an upward trend, low density lipoprotein was significantly lower than that of the control group. Egg fat: the cholesterol of egg yolk in the trial group was significantly lower than that in the control group (P0.05). There was no significant difference between the control group and the control group in the triglyceride content of egg yolk triglyceride in the trial group and in the control group, which were significantly lower than those in the control group (P0.05), and there was no significant difference between the control group and the control group in the content of triglyceride of egg yolk. With the increase of perilla seed supplementation level, each index showed a downward trend compared with the control group, and there was no significant difference in the activity of FAS enzyme between the two groups. The FAS enzyme activity of the 4 groups was significantly lower than that of the control group (P0.05), and there was no significant difference in the activity of FAS between the two groups (P0.05). The activity of HMG-CoA enzyme in the experimental group was significantly lower than that in the control group (P0.05). The effect of perilla seed on immune function in the control group: the total protein in the test group was significantly higher than that in the control group (P0.05). There was no significant difference in the white ball ratio between the four groups (P0.05), but there was no significant difference in the white ball ratio of the other groups (P0.05), but there was an upward trend in the test group compared with the control group. The titer of serum H5 H9 type avian influenza antibody in the control group was significantly higher than that in the control group (P0.05), but there was no significant difference among the other groups. The results showed that 2% perilla seed could improve the performance of native layer hens, reduce blood lipid and egg fat, and improve immune ability.
