摘　　要：分别选用颗粒料和营养舔砖补饲枯草期的藏母羊,以探讨妊娠后期至哺乳前期补饲藏母羊对其羔羊生产性能的影响。结果表明,颗粒料补饲藏母羊能显著提高其羔羊的初生重(P<0.05)、断奶重(P<0.01)、羊毛密度(P<0.01)、羊毛长度(P<0.05)及产毛量(P<0.01);补饲营养舔砖也能显著提高其羔羊的断奶重(P<0.01)、羊毛密度(P<0.05或P<0.01)和产毛量(P<0.05),而对羔羊的初生重和羊毛长度无显著影响(P>0.05)。Pellets and nutrition licking bricks were used to feed Tibetan ewes during dry period to study the effect of feeding Tibetan ewes on production performances of their lambs at the stage of late pregnancy to early lactation.The results show that feeding Tibetan ewes with pellets can significantly improve their lamb＇s birth weight（P0.05）,weaning weight（P0.01）,wool density（P0.01）,wool length（P0.05） and wool yield（P0.01）.Feeding Tibetan ewes with nutrition licking blocks can significantly improve their lamb＇s weaning weight（P0.01）,wool density（P0.05 or P0.01） and wool yield（P0.05）,while the lamb＇s birth weight and wool length was no significant difference（P0.05）.
