Effects of Compound Plant Extracts on Growth Performance,Slaughter Performance and Meat Quality of Broilers
摘要
Abstract
The aim of this experiment was to investigate the effects of the compound plant extract composed of Astragalus membranaceus,Epimedium and Ligustrum lucidum on the growth performance,slaughter per-formance and meat quality of broilers.A total of 120 one-day-old 817 white-feathered broilers were selected and divided into two treatment groups:the control(CON)group and the 0.3%compound plant extract(CPE)group,with 60 broilers in each group.Broilers were raised in two periods:1-21 days and 22-42 days.The results showed that:① the average daily gain of CPE group was significantly higher than that in the control group(P<0.05),and the feed-to-gain ratio was significantly lower than that in control group(P<0.05).② The metabolic rates of crude protein and phosphorus throughout the entire period and crude fat in the later stage of feeding in CPE group were significantly higher than those in control group(P<0.05).③ The carcass rate and breast muscle pH of CPE group were significantly higher than those in control group(P<0.05).④ The mRNA expression of HO-1 of the CPE group in pectoral muscle were significantly higher than in control group(P<0.05).The mRNA expression levels of TNF-α and IL-1β were significantly lower than that in the control group(P<0.05).At the same time,the expression level of Nrf2 protein in the breast muscle tissue of CPE group was significantly higher than that in control group(P<0.05),and the expression level of NF-κB protein was significantly lower than in control group(P<0.05).In conclusion,adding a compound plant extract to the diet can improve the nutrient metabolism rate of broilers,enhance the antioxidant and immune capabilities of the breast muscle tissue,and thereby improve growth performance,feed utilization rate and meat quality.关键词
