摘要: 【目的】研究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。【方法】选取540只42日龄黄羽肉鸡,随机分为3组(每组6个重复,每个重复30只):对照组肉鸡饲喂基础饲粮,试验组分别在基础饲粮中添加0.5%腐殖酸钠和酸化剂(0.5%组)以及1%腐殖酸钠和酸化剂(1%组),其中腐殖酸钠和酸化剂由腐殖酸钠、柠檬酸钙和乳酸钙组成,比例是5∶4∶1。试验为期21 d,试验结束时,以重复为单位称取肉鸡的空腹重,测定肉鸡的生长性能;每个重复随机选取2只体重接近平均体重的肉鸡屠宰,测定肉鸡的屠宰性能和脏器系数;取两侧胸肌,测定肌肉抗氧化和肉品质指标。【结果】①与对照组和1%组相比,0.5%组黄羽肉鸡的终末体重(FW)、平均日增重(ADG)、胸肌率、脾脏指数、总超氧化物歧化酶(T-SOD)活性和胸肌的pH45 min显著提高,而料重比(F/G)、腹脂率、胸肌滴水损失和剪切力显著降低(P<0.05)。②与对照组相比,0.5%组黄羽肉鸡胸肌中丙二醛(MDA)浓度显著降低(P<0.05)。【结论】饲粮中联合添加0.5%腐殖酸钠和酸化剂可显著提高黄羽肉鸡生长性能、屠宰性能和胸肌的抗氧化功能,并改善肉品质。

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 pH45 min 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.
