摘　　要：目的比较研究广州地区西藏小型猪F1代与F0代引入群母猪繁殖和仔猪生长性能的差异。方法观察记录西藏小型猪F1代和F0代的产仔数、产活仔数、离乳仔数、初生重、30日龄和60日龄体重。结果西藏小型猪F1代和F0代母猪其初产平均产仔数、产活仔数、离乳仔数、平均初生重、30日龄和60日龄体重分别为3.83头、2.30头;3.29头、2.20头;3.14头、3.11头;0.66 kg、0.53 kg;2.70 kg2、.30 kg;4.50 kg、4.01 kg;F1代初产仔数和离乳率均显著高于F0代。结论西藏小型猪已经适应了广州高温高湿环境,能够稳定地生长繁殖。Objective The differences of growth and reproductive perfomanee between F1 and F0 generations of Tibet mini-pigs raised in Guangzhou were investigated. Methods Litter size, number of births alive, number of piglets weaned and body weight at birth, 30 days and 60 days of F1 generation after birth were measured and compared with those of F0. Results The findings indicated that litter size, number of births alive and number of piglets weaned, the average body weight at birth, 30 days and 60 days of F1 and F0 after birth were 3.83, 2.30; 3.29, 2.20;3.14, 3.11 ; 0.66 kg, 0.53 kg; 3.20kg, 2.30 kg; 4.50 kg, 4.01 kg, respectively. Litter size and Survival rate after weaning of F1 are higher than that of F0. Conclusions The Tibet mini-pigs have adapted to the environment in Guangzhou and are able to normally grow and reproduce.
