联合使用腐殖酸钠和酸化剂对黄羽肉鸡生长性能和肉品质的影响
Effect of Combined Use of Sodium Humate and Acidifier on Growth Performance and Meat Quality of Yellow Feather Broilers
摘要
Abstract
[Objective]The purpose of this study was to investigate the effects of sodium humate and acidifier on growth performance and meat quality of Yellow feather broilers.[Method]A total of 540 Yellow feather broilers at 42 days were randomly divided into 3 groups(6 replicates per group,30 birds per replicate).The broilers in control group were fed the basal diet and the broilers in test group were fed the basal diet added with 0.5％sodium humate and acidifier(0.5％group)and 1％sodium humate and acidifier(1％group),respectively.Among them,sodium humate and acidifier consisted of sodium humate,calcium citrate and calcium lactate in the ratio of 5:4:1.The test was conducted for 21 d.The fasting weight of broilers was weighed in replicates were used to calculate the growth performance of broilers,and two broilers with body weight close to the average weight were randomly selected for slaughter in each replicate group to determine the slaughter performance and organ index of broilers.Pectoral muscles on both sides were taken and used to determine muscle antioxidation and meat quality index.[Result]①Compared with the control and 1％groups,the final weight(FW),average daily gain(ADG),pectoral muscle rate,spleen index,total superoxide dismutase(T-SOD)activity and pH45min of pectoral muscle were significantly higher in 0.5％group of Yellow feather broilers,while the feed-to-weight ratio(F/G),abdominal fat rate,drip loss fraction and shear force of pectoral muscle were significantly lower(P＜0.05).②The concentration of malondialdehyde(MDA)in the pectoral muscle of Yellow feather broilers in the 0.5％group was significantly lower compared to the control group(P＜0.05).[Conclusion]The combined supplementation of 0.5％sodium humate and acidifier in the diet could significantly increase the growth performance,slaughter performance,and antioxidant function of pectoral muscle of Yellow feather broilers,and improve meat quality.关键词
