Selenium (Se) is an essential trace element for animal and human. Supplementation of Se usually in livestock diet has been proved as effective element. This study was conducted to investigate the effect of different sources of selenium on growth performance, slaughter performance, immune trait, oxidation resistance, meat quality and selenium content in tissue of broilers to comprehensively evaluate the effect of selenium. A total of 324 1-day-old AA broilers were selected and randomly allocated to three treatments of six replicates with 18 broilers each. The trial period was 42 days and was divided into two periods. Our results showed that effect of different sources of selenium on growth performance, slaughter performance, the immune status, drip loss and flesh had not significant difference (p > 0.05); while the activities of serum glutathione peroxidase (GSH-Px), total superoxide dismutase (T-SOD), the abilities to inhibit hydroxyl radical (OH˙) and total antioxidant capacity (T-AOC) were significantly higher in selenium yeast than sodium selenite groups, and the contents of MDA of selenium yeast groups were significantly lower than that of sodium selenite. This study demonstrated that the different sources of selenium had no obvious effect on production performance of broilers, but significantly influenced the broiler oxidation resistance.
硒（Se）是动物和人类必需的微量元素。在牲畜日粮中添加硒通常已被证明是一种有效的元素。本研究旨在探讨不同硒源对肉鸡生长性能、屠宰性能、免疫特性、抗氧化性、肉质及组织中硒含量的影响，以全面评估硒的作用。共选取324只1日龄AA肉鸡，随机分为3个处理，每个处理6个重复，每个重复18只肉鸡。试验期为42天，分为两个阶段。我们的结果表明，不同硒源对生长性能、屠宰性能、免疫状态、滴水损失和肉质没有显著差异（p>0.05）；而硒酵母组血清谷胱甘肽过氧化物酶（GSH-Px）、总超氧化物歧化酶（T-SOD）活性、抑制羟自由基（OH˙）能力和总抗氧化能力（T-AOC）显著高于亚硒酸钠组，硒酵母组丙二醛（MDA）含量显著低于亚硒酸钠组。本研究表明，不同硒源对肉鸡生产性能无明显影响，但对肉鸡抗氧化性有显著影响。
