| 中文摘要: |
| 文章主要探讨批次化生产与定时输精技术对母猪利用及淘汰的关系。结果显示，2019-2020年该场母猪淘汰率为36.63%，而0-2胎占全部淘汰母猪比例的65.76%。结果表明，批次化生产和定时输精确实有利于生物安全防控，提高工作效率，但储备大量后备猪是必要前提。 |
| 英文摘要: |
| The article mainly discussed the relationship between batch production and timed insemination technology for the utilization and elimination of sows. The results showed that the culling rate of sows in this farm from 2019 to 2020 was 36.63%, and 0-2 litters accounted for 65.76% of all culled sows. The results showed that batch production and precise timing insemination were beneficial to biosafety prevention and control and improve work efficiency, but a large reserve of pigs was a necessary prerequisite. |
