Abstract
The disclosure relates to a batch management method for improving the farrowing rate or the number born alive in swine. It includes the following steps: synchronization of estrus in swine are used an exogenous gonadotropin(s) to synchronize follicular development, and then fed with 1-[bis(4-cyanophenyl)alkyl]-1,2,4-triazole after 6-12 hours. Next the gilts or sows are bred in batches after treated with ovulation-inducing drug(s). The disclosure can effectively alleviate decreased farrowing rate and number of piglets born alive in the batch gilts or sows used the fixed-time artificial insemination, without influencing the serum estrogen level, estrus and ovulation time in mated gilts or sows. Therefore, a novel method for improving the reproductive efficiency of gilts or sows will be established, which is valuable for popularizing batch farrowing in swine including with fixed-time artificial insemination.
