摘　　要：选用本地肉犬作为试验材料，在总能１６．０８～１６．４６ＭＪ／ｋｇ，粗蛋白质１６．１５％～１８．１２％的饲粮营养水平下，采用湿拌料生喂、适度规模封闭式圈养方式，以探讨其圈养技术及效果。结果观察到本地母犬的平均妊娠期为６０．４３ｄ，初胎总产仔数５．０８只，活产仔数４．７１只，初生窝重１．６５ｋｇ，４５日龄断奶窝重１５．３９ｋｇ；４５日龄断奶后的幼犬，经过３个月的饲养，体重可达到１２．８９ｋｇ，饲养期平均日增重９２．７８ｇ，料肉比３．５９∶１，日采食量３３２．８２ｇ，胴体屠宰率为６２．０３％，净肉率７３．７９％。此外，本地肉犬的最适宜上市体重为１０ｋｇ左右。The technology and its effect of pen rearing of local meat dogs were studied at the nutrient level of GE 16.08～16.46MJ/kg and CP 16.15%～18.12% by raw and wet feeding at moderate density. The result showed that, on the average, the pregnancy duration of the bitch is 60.43 d, farrowing number of the first-born 5.08, among which that of the survival 4.71, litter weight at birth and 45d old was 1.65kg and 15.39kg respectively;The body weight of the puppy weaned at 45d old could reach to 12.89kg after three months'rearing. So, daily weight gain and consumed feed amounted to 92.78g and 332.82g, respectively, presenting a ratio of 3.59∶1 (feed to meat). Its dressing percentage and net meat percentage of carcass reached 62.03% and 73.79%, separately.In addition, its optimum market weight is about ten kilogram.
