Abstract:
One hundred and twelve anestrus sows were injected with the high quality reproductive hormone(FD-600).The results showed that the effects of parity and fatness of sows on the reproductive regulation of exogenous hormone were significant.(1) The estrus rate and the farrowing rate of gilts were 80% and 25%,and that of the mutiparous sows were 92.3% and 58.3%.(2) The estrus rate of the fattest sows was the lowest(0),and that of the others was 100%.The farrowing rate of the fattest and thinnest sows was the lowest(0),and the farrowing rates of mid fatness sows,fatter sows and thinner sows were 46.15%,31.25% and 68.75%,respectively.
