湖羊羔羊不同强制补饲方式效果对比试验OA

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 .
