摘要
[目的]探讨日粮中添加硒对滩羊胴体品质的影响,为生产特色滩羊肉提供技术支持。[方法]在滩羊日粮中添加0.35 mg/kg(试验组)和0.30 mg/kg(对照组)硒进行饲养试验,研究富硒日粮对滩羊胴体品质的影响。[结果]试验组滩羊胴体净肉率和肉骨比值较对照组分别提高2%和9.6%;试验组滩羊香味氨基酸、脯氨酸和赖氨酸含量比对照组提高1.2%、3.8%和21%。试验组镁、钙和钾含量较对照组分别提高31.12%、12.76%和24.77%;试验组滩羊体内硒含量比对照组提高10%。[结论]日粮中添加适量的硒能够提高胴体净肉率、肉骨比值以及镁、钙、钾和硒含量。
Abstract [ Objective ] The research aimed to discuss the effects of adding selenium in the diet on the carcass quality of Tan Sheep and provide scientific support for producing characteristic meat of Tan Sheep. [ Method] 0.35 mg/kg selenium （ test group） and 0.30 mg/kg selenium （ con- trol group） were added in the diet of Tan Sheep to make the feeding experiment. The effects of selenium -enriched diets on the carcass quality of Tan Sheep were studied. [ Result] The net meat percentage and meat-bone ratio of Tan Sheep in test group was 2% and 9.6% higher than that in control group. The contents of flavor amino, proline and lysine in test group were increased 1.2%, 3.8% and 21% than that in control group respectively. The contents of magnesium, calcium and potassium in test group were 33.1%, 12.76% and 24.77% higher than that in control group, respectively. Selenium content in test group was increased 10% than that＇in control group. [ Conclusion] Adding suitable amount of sele- nium in the diet could enhance the net meat percentage, meat-bone ratio, and the contents of magnesium, calcium, potassium and selenium.
