Carbetocin-induced synchronous daytime parturition in sows
摘要
Abstract
The experiment was conduct to study the optimal dosage of carbetocin and its effect on inducing synchronous parturition in daytime in sows.A total of 98 parturient sows were randomly divided into 4 groups.After delivering one piglet,the sows were respectively injected with 17.5 μg,35 μg,70 μg of carbetocin into the neck muscle in test groups 1,2 and 3,while the sows in control group were injected with 1 mL of saline.And the farrowing interval of sows,the time of placental expulsion,the proportion of assisted delivery,the total number of piglets per litter,the number of stillbirths and mummies of the sows were recorded.Then 2 834 parturient sows from 19 large-scale pig farms were divided into two groups.1 335 sows were injected with cloprostenol sodium at 9 AM on the 114th day of gestation,and 1 499 sows were injected with cloprostenol sodium at 9 AM on the 114th day of gestation,and with carbetocin at an interval of 24 hours.The average farrowing length of sows,interval between litters,the total number of piglets per litter,average litter size,the number of white stillbirths per litter,percentage of daytime births,and postpartum uterine inflammation of sows were recorded.The results showed that compared with the control group,all carbetocin treatment groups could significantly shorten the inter-piglet intervals of sows(P<0.05),among which Group 2(35 μg/sow carbetocin)had the best effect.Therefore,a dose of 35 μg per sow of carbetocin injection was selected for subsequent studies on synchronized farrowing in daytime.The combined treatment of cloprostenol and carbetocin could significantly increase the parturition rate in daytime of sows,reduce average farrowing duration and inter-piglet intervals(P<0.001),reduce the occurrence of white stillbirths(P<0.05),and reduce the occurrence of postpartum inflammation of sows(P<0.05).In conclusion,carbetocin combined with cloprostenol sodium can efficiently induce synchronous parturition in daytime in sows,meanwhile improve the health status of sows and piglets,provide a solid and powerful support for batch production in large-scale pig farms.关键词
