| 中文摘要: |
| 发酵饲料是符合健康养殖理念的环保型饲料，具有提高饲料利用率及动物生产能力，改善动物健康水平，减少抗生素使用与环境污染，保障人类健康安全等作用。在养猪生产中发酵饲料具有良好的研究价值和应用前景。因此，文章综述了发酵饲料的生产方式、工艺技术控制，以及发酵饲料在养猪生产中不同生长阶段的应用情况，以期为相关领域提供新的思路和方法。 |
| 英文摘要: |
| Primiparous sows’ reproductive performance in three years including the litter size， number born alive，death litter size， number of mummies， number of fetal malformation and number of weak piglets were collected， and the effect of different estrum on sows’reproductive performance were analyzed. Compared to the sows of the primary mating in the second estrum， the differences of the average litter size were not obvious among the sows of the primary mating in the third and fourth estrum， the survival number was increased remarkably， primary mating breeding rate has a remarkable increase， less differences in the average dead number， obvious reduction of the mummy number and less differences in the weak piglets number. Consequently， with postponing entering of the estrum properly and increasing the conditions of the estrum， the survival piglets number can be improved，the average mummy number can be lowered，which improved the breeding rate of the sows. |
