有机硒对肉鸡生长性能、屠宰性能、肉品质及抗氧化性能的影响
Effects of organic selenium on growth performance,slaughter performance,meat quality,and antioxidant capacity of broilers
摘要
Abstract
This study aimed to investigate the effects of organic selenium on the growth performance,slaughter performance,meat quality,and antioxidant capacity of broilers.A total of 360 one-day-old Ross 308 broilers were randomly divided into three groups,with six replicates in each group and 20 chickens in each replicate.The Na2SeO3 group,Se-Met group,and Nano-Se group were supplemented with sodium selenite,selenomethionine,and nano selenium at a selenium level of 0.4 mg/kg,respectively.The experimental period was 42 days.The results showed that during the 1～21 d,the feed-to-gain ratio of the Se-Met group was significantly lower than that of the Na2SeO3 group(P＜0.05).The abdominal fat percentage of the Nano-Se and Se-Met groups was significantly lower than that of the Na2SeO3 group(P＜0.05).Compared with the Na2SeO3 group,the a*value of the pectoral muscle in broilers from the Nano-Se group was significantly increased(P＜0.05),and the water-holding capacity of the pectoral muscle in broilers from the Se-Met and Nano-Se groups was significantly increased(P＜0.05).Compared with the Na2SeO3 group,the total antioxidant capacity(T-AOC),superoxide dismutase(T-SOD),and glutathione peroxidase(GSH-Px)activities in the pectoral muscle from the Nano-Se group were significantly increased(P＜0.05),and the malondialdehyde(MDA)content in the pectoral muscle of broilers from the Se-Met and Nano-Se groups was significantly reduced(P＜0.05).The study indicates that organic selenium can effectively improve the growth performance,slaughter performance,meat quality,and antioxidant capacity of broilers,with nano selenium showing better effects than selenomethionine.关键词
