摘要
在洮南市向阳乡选择符合要求的养羊户9户,每户选出10～15只体重和膘情相近的哺乳期产单羔繁殖母羊组成试验组参加试验。本试验设定日粮代谢能和粗蛋白质2个试验因子,每个因子设定3个处理水平。总结日粮代谢能和粗蛋白质的供给水平对哺乳母羊体重变化和对羔羊生长发育的综合影响,建议在生产中提供代谢能9.00 MJ/kg、粗蛋白10.00%的日粮饲喂哺乳期繁殖母羊。
9 families in Xiangyang town of Taonan city were chosen and 10 to 15 ewes of each family were selected in the experiment. The ewes were same in weight and fatness and at lactation period. Two factors, i.e., metabolizing energy and coarse protein in daily ration were analyzed and 3 level for each factor set. The results showed that taking integrated effect of metabolizing energy and coarse protein in daily ration on ewe＇s weight and growth of lamb into consideration, it was suggested that 9.00 MJ/kg of metabolizing energy and 10.00% of coarse protein in daily ration should be provided for ewes at lactation period in production.
