湖羊羔羊不同强制补饲方式效果对比试验

湖羊养殖在我国己形成一条产业链,对助力脱贫攻坚向乡村振兴有效衔接具有重要意义。但是在生产实践中发现湖羊羔羊产羔多，成活率低，生长发育慢，母羊乳房炎发病率高。近年来采取强制补饲技术提前锻炼羔羊的消化系统，取得了较好的效果。本研究在规模化湖羊养殖场开展了精料与精料+牧草两种强制补饲饲喂方式对比，从羔羊生长速度、消化道生长发育、屠宰性能和胃肠道的组织形态学等方面进行了比较，发现精料+牧草的早期强制补饲方式效果明显好于单纯的精料组。研究结果为规模化湖羊养殖场提高羔羊的成活率、降低母羊乳房炎发病率，促进湖羊养殖提质增效具有十分重要的意义。

Comparative Experiment on Effects of Different Forced Supplementary Feeding Methods for Hu Lambs

Hu sheep breeding has formed an industrial chain in China, which is of great significance in helping to effectively link poverty alleviation to rural revitalization. However, we have found in production practice that Hu lambs have many lambs, low survival rate, slow growth and development, and a high incidence of mastitis in ewes. In recent years, we have adopted compulsory supplementary feeding technology to exercise the digestive system of lambs in advance, and achieved good results. In this study, two forced supplementary feeding methods of concentrate and concentrate + grass was compared in a large scale Hu sheep farm. The lambs were compared in terms of growth rate, growth and development of digestive tract, slaughter performance and histomorphology of gastrointestinal tract. We found that the effect of early forced supplementary feeding of concentrate + grass was significantly better than that of pure concentrate group. The research results are of great significance for large scale Hu sheep farms to increase the survival rate of lambs, reduce the incidence of mastitis in ewes, and improve the quality and efficiency of Hu sheep breeding.
