贾洛绵羊(原名:阿坝藏系绵羊贾洛绵羊)是从藏系绵羊分离出来的优良类群,近年来通过对贾洛绵羊杂交改良试验,得出贾洛绵羊为父本杂交后代的生产性能远远高于其他本地品种,对于优良品种极度缺乏的青藏高原高寒牧区,是一个极其重要的绵羊遗传资源.种公羊管理的优劣直接影响养羊户(场)的经济效益,因此对种公羊应合理饲养、科学管理.

1 加强妊娠期母羊营养 妊娠期营养不良母羊所产羔羊体重较轻,其死亡率上升.此外,妊娠期营养不良母羊对羔羊的攻击性较强,照料羔羊的时间少,有可能抛弃羔羊,这样会增加了羔羊的死亡率. 1.1 妊娠前期饲养 妊娠前期是指母羊妊娠后的前3个月,此期间胎儿发育减慢.妊娠前期应注意满足母羊的营养需要,使其处于配种时的体况.怀孕前期母羊对粗饲料的消化能力较强,此期可用优质秸秆代替部分干草进行饲喂,同时适量补饲优质干草或青贮饲料等.

In this research, the body weight and body size of Jialuo sheep from weaning to adult were measured. By comparing and analyzing the growth and development features in different age to provide reliable scientific basis for the early utilization and scientific selection as well as ex-cavating potential productivity of Jialuo sheep.
