%X 作者指导邵阳县五峰铺镇某猪场，采取每批次前早2个情期延期配种，每批次后1个情期用促性腺激素催情和排卵，促进性周期性同步配种方法，2017、2018、2019年母猪繁殖成绩和仔猪整齐度大幅提高，工作效率提高。母猪批次化生产的产仔数，20 d活仔数，初生重，20 d窝重比常规化生产比较，分别提高11.69%、10.97%、1.44%、3.54%。与前人研究的母猪三周批次、四周批次生产减少劳动强度，母猪繁殖成绩上升结果一致。并对前人母猪批次化生产技术的优点、要点和使用促性腺激素经验进行了研究，供同行参考。<br />
The author guided a pig farm in Wufengpu Town, Shaoyang County to adopt a delayed breeding method of two estrus periods before each batch, and one estrus period after each batch using gonadotropins to induce estrus and ovulation, promoting periodic synchronous breeding. In 2017, 2018, and 2019, the reproductive performance of sows and the uniformity of piglets were significantly improved, resulting in improved work efficiency. Compared with conventional production, the number of sows produced in batches, 20 day live piglets, birth weight, and 20 day litter weight increased by 11.69%, 10.97%, 1.44%, and 3.54%, respectively. The results are consistent with previous studies on the reduction of labor intensity and the improvement of sow reproductive performance in three week and four week batches of sow production. And the advantages, key points, and experience in using gonadotropins of previous batch production techniques for sows were studied for peer reference.
