理想的母猪群胎次结构应当是：第一胎母猪占21%。第二胎占19%。第三胎占16%。第四胎占13%。第五胎占12%。第六胎占11%。第七胎以上占8%，以确保繁殖效率和经济性。在实践中，通过精心设计早期妊娠检查方案，可以有效地发现空怀母猪，并及时促进其发情，提高配种成功率。此外，对于发情和返情的认真监测至关重要，尤其是在配种后关键时段进行查情，以确保不错过任何繁殖机会。
为了提升查情技术，应定期使用成熟公猪对母猪进行刺激，每天至少进行两次查情操作，一次在喂食后30分钟，一次在下班前。这有助于检测返emotion mother pigs and improve the overall reproductive performance. Furthermore, it is crucial to select experienced and mature boars for this purpose, ensuring that they are at least 12 months old, move slowly, and have a high amount of foam in their mouth.
Lastly, optimizing non-reproductive days is vital for maximizing productivity. By minimizing non-production days (the time spent on non-pregnancy and non-lactation periods), farms can significantly reduce costs while maintaining a healthy population. The ideal range for non-production days should be between 30-35 days for top-performing farms and 40-45 days for average performers. This ensures that resources are allocated efficiently towards breeding purposes.
