Effects of Altrenogest Treatment on Reproduction of Primiparous Sows
摘要
Abstract
In order to solve the breeding performance barriers of primary sows and to reduce production costs,primary sows were se-celeted and divided into 3 group,control group,FTAI group and Altrenogest+FTAI group before weaning in this experiment respective-ly.The main results were as follows:(1)The participating sows farrowing rate of Altrenogest+FTAI group(79.74％)and FTAI group(77.90％)were higher than that of the control group(60.45％)(P＜0.01),and the participating sows farrowing rate of Altrenogest+FTAI group(80.47％)and FTAI group(72.96％)were higher than that of the control group(35.28％)in thin backfat group of primiparous sows(P＜0.01),and the participating sows farrowing rate of Altrenogest+FTAI group(100.00％)was higher than that of the control group(44.44％)in fatty backfat group of primiparous sows(P＜0.01);(2)The total numbers of born(TNB)of Altrenogest+FTAI group(13.07)was higher than that of the control group(11.37)(P＜0.01),and the total numbers of born(TNB)of FTAI group(12.76)was higher than that of the control group(P＜0.05),and the total numbers of born(TNB)of Altrenogest+FTAI group(13.18)was higher than that of the control group(10.61)in moderate backfat group of primiparous sows(P＜0.05),and the numbers of born qualified of Altrenogest+FTAI group(11.62)and FTAI group(11.59)were higher than that of the control group(10.50)(P＜0.05);(3)And the numbers of feeding days of partic-ipating sow needed per total piglets of Altrenogest+FTAI group(12.63)and FTAI group(13.74)were less than that of the control group(16.27)in thin backfat group of primiparous sows P＜0.01),and the numbers of feeding days of participating sows needed per alive piglets of Altrenogest+FTAI group(13.36)and FTAI group(14.24)were less than that of the control group(16.99)in thin backfat group of primiparous sows(P＜0.01),and the numbers of feeding days of participating sows needed per qualified piglets of Altrenogest+FTAI group(13.78)and FTAI group(14.72)were less than that of the control group(17.20)in thin backfat group of primiparous sows(P＜0.01).Conclusions:The treatment method of Altrenogest+FTAI group was better to improve the participating sows farrowing rate of primi-parous sows in the thin backfat primiparous sows and the fatty backfat primiparous;The treatment methods of Altrenogest+FTAI group was better to improve the total number of born(TNB)of primiparous sows in the moderate backfat primiparous sows;and the treatment method of Altrenogest+FTAI group was better to reduce the number of feeding days of participating sow needed per total piglet the number of feeding days of participating sow needed per alive piglet and the number of feeding days of participating sow needed per qualified piglet in the thin backfat primiparous sows.关键词
