【摘要】：合作猪(藏系猪)俗称蕨麻猪、藏猪、山猪,是我国最宝贵的动物品种资源之一。经调查,在合作猪主产区合作猪饲养模式主要有4种:终年放牧模式、春夏舍饲秋冬放牧、春夏放牧秋冬舍饲模式和全舍饲养殖模式;试验选择生长发育、体重、营养状况基本一致的150头1月龄合作猪,分为6组,分别以方式(1)、(2)、(2-1)、(3)、(4)、(4-1)模式养殖,同时测定纯放牧模式、春夏舍饲秋冬放牧、春夏放牧秋冬舍饲模式下80头母猪的繁殖性能。试验结果表明,模式(4-1)和模式(2-1)增重效益显著高于其他模式(P0.05),春夏放牧秋冬舍饲模式下合作的猪繁殖性能最佳,其次为春夏舍饲秋冬放牧模式,纯放牧模式下窝仔数、仔猪初生重、繁殖成活率均显著低于前两者(P0.05)。
[Abstract]:Hezuo Pig (tebetan pig) commonly known as Tibetan Pig, pig, pig, is one of the most valuable animal breed resources in China. After investigation, the main producing areas of cooperation cooperation pig pig breeding mode mainly has 4 kinds: spring summer autumn and winter year-round grazing patterns in spring and summer autumn and winter grazing, grazing feeding mode and full feeding mode test selection; growth, weight, nutritional status is basically the same 150 head 1 month old pigs, divided into 6 groups, respectively by means of (1), (2), (2-1), (3), (4), (4-1) mode of breeding, simultaneous determination of pure spring and summer autumn and winter grazing grazing patterns, feeding. The reproductive performance of 80 sows in spring and summer autumn and winter grazing feeding mode. Test results show that the model (4-1) and (2-1) weight gain benefit was significantly higher than that in other mode (P0.05), spring and summer autumn and winter grazing in the mode of cooperation of porcine reproductive performance is best, the time for spring and summer in autumn and winter grazing patterns, litter nest pure grazing under the mode of piglets The primary weight and the survival rate of reproduction were significantly lower than those of the former two (P0.05).
