摘要
通过常规方法,对引入到广州地区的藏猪G1代进行了生长发育和繁殖指标的测定,包括G1代藏猪不同月龄的体重、体尺(体高、体长、胸围)值。测定母猪每胎产仔猪数、初生头重、离乳数和离乳率等。结果表明:藏猪繁殖力的各项指标高于原产地放牧藏猪猪群,而低于舍饲的藏猪猪群;雌雄藏猪体重相比较,除了1月龄有极显著性差异(P<0.01)和2月龄有显著差异(P<0.05)外,其余月龄雌雄之间均无差异;体尺值随月龄增长逐渐增加,不同性别之间,除6月龄体高雄性高于雌性外(P<0.05),其余月龄不同性别藏猪均无差异(P>0.05)。说明经过2年的风土驯化,藏猪基本适应了亚热带气候环境,能够正常生长繁殖,并且保持了生长缓慢、小体型的特点,非常适合用于动物实验研究。
To study the traits on the growth and development and reproduction of Tibet hogs in subtropics, basic datas of Tibet hog were tested including body weight, body height, body length and breast circumference with conventional methods. Breeding condition was determined too, such as the performances of initial weight, ablactational number and ablactational rate,etc. The result showed that reproductive ability of Tibet hog in Guangzhou area is higher than that of stock pigs but lower than that of closed pigs in Tibetan area . There were no significant differences between sexes on the body weight except in 1 and 2 months old Tibet hogs. The differences al~ had no statistical significance between sexes on the size of the body except 6 months old Tibet hogs. Tibet hog are acclimatized to the environment in the subtropics through endemic domestication in the past two years, and will be suitable to be used as experimental animal for its small body size and low average daily gain.
