湖羊羔羊不同强制补饲方式效果对比试验

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

摘要:

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。

Abstract:

Hu sheep breeding has formed an industrial chain in China, which is of great significance to effectively link poverty alleviation to rural revitalization. However, in the production practice, it was found that the Hu sheep produce more lambs, have low survival rate, and grow slowly, and have a high incidence rate because of ewe mastitis. In recent years, forced supplementary feeding technology has been adopted to exercise the digestive system of lambs in advance, and good results have been achieved. This study carried out a comparison of two forced supplementary feeding methods of concentrate and concentrate + forage in a largescale Hu sheep breeding farm, and made a comparison from the growth rate, growth and development of digestive tract, slaughter performance and histomorphology of gastrointestinal tract of lambs. Results showed that the effect of early forced supplementary feeding of concentrate + forage was significantly better than that of concentrate alone. The research results are of great significance for the largescale Hu sheep breeding farm to improve the survival rate of lambs, reduce the incidence rate of ewe mastitis, and promote the quality and efficiency of Hu sheep breeding.
