Study On Reproductive Performances And Taming Of Wild Boar

This paper studied biologial character,taming conditions,taming method, house construction,compose of diet,reproduction performances , prevention and treatment of disease of boar in taming condition. First studied gency estrua, conception embrogy , product descendent with external hormone PMSG and HCG in aneatrus and in lately autumn and early winter.The results showed that living habits ,acquired food characteristics and reproduction performance were completely considered when wide pigs were tamed. Construction house were paid attention to choose,solid,defend flee ,ray of light and light up, keep warm,isolate hot,airy and exchangr air. The effecte of pens on the ecological habit and reproduction performance of wild pigs is significant. The time of wild pigs lying to relax increased by 2.7h/d;The legs and feet lesion decreased by 2 times/30d ;Besides their normal intade,the state that wild pigs run out of pens has also been controled.Compared to domestic pigs ,the estruscycle of wild pigs is advanced 1d ,that is 21.50+0.58d , and the gestation is shortened 1.5d. that is 114.5+1.29d .The average farrow and 2-month weanling weight increased by 0.6 head and 0.51kg, respectively. After comprehensive taming .the time wild boars and wild sows from refusing to intake to adlibitum and their knowing to drink with automatic drindker is 14.50+0.58d,15.50+0.86d,14.00+0.50d and 14.50 + 0.62d, respectively. Besides , thetime from being alarmed to be closeness is 32.50+0.50d. The rate succeeding to tame wild male piglets and wild female piglets is 75% and 100%,respectively.All the tested pigs Including wild boars ,wild sows and wild piglets are fed certain diets, teeir feed and tain ratio is 5.37:1, 5.05:1 and 4.54:l,respectively.HCG and PMSG were alone used to for guiding oestrus of wild sows in non oestrus reason. They were not significantly difference between reducing diet ,(P=0.589,P>0.05). Red swelling moist change of external private parts were significantly different ,(Fisher's Exact TEST,2-Tail, P=3.12e-08,P<0.01). Breeding situation of each group were not significantly difference,. (Fisher's Exact TEST,2-Tail, P=0.758,P<0.01). PMSG and HCG were applied in late autumn and early winter. Compared to controled group ,the oestrus rate and conception rate and live farrowingrate of test group increased by 37.5%,27.5%,4.99% and the average litter also increased by 0.96.
