How do I improve sow performance?怎样提高母猪性能
Reduce mycotoxins 减少霉菌毒素
Multiple feedings/day of fresh, nutrient dense feed每天多次饲喂新鲜的,高营养浓度的饲料(泌乳期)
Provide supplemental feed to nursing litters乳猪补料
Do not overfeed during gestation 怀孕期不要饲喂过多
Bring sows up to full feed in lactation gradually (Reach full intake by d-8 of lactation) 泌乳期逐渐到达充足饲喂(泌乳第8天达到充足饲喂)
Fiber source during gestation 怀孕期纤维饲料

Why do you need good gilt management???为什么需要良好的后备母猪管理???
Goal of Efficient Gilt Management Systems:有效的后备母猪管理系统的目标
To meet gilt replacement needs from a smaller pool of gilts with improved lifetime performance用较少的、高性能的后备母猪满足母猪更换的需要
Measurement 测量指标
Mean平均
Upper 10%
最好10%
Lower 10%
最查10%
Average female inventory平均母猪存栏
1046


Replacement Rate更换率



Average parity平均胎次



2002 Breeding Herd Summary for Canada2002年加拿大配种母猪群总结

dae_meng
Highest % of farrowings in the herd 母猪群高分娩率
Breeding targets配种目标
Replace involuntary fallouts更换偶然的落后的猪
Replace voluntary culling更换主动的淘汰的猪
Important to maintain parity structure 对于维持胎次结构很重要

Why are Gilts SO IMPORTANT?为什么后备母猪如此重要?

Requirements for meeting breeding targets满足配种目标的要求
Proper gilt pool size and effective gilt pool management to meet gilt breeding targets 合适的后备母猪群大小和有效的后备母猪群管理来满足后备母猪的配种目标
Predictable numbers of weaned sows 可以预测的断奶母猪数

The challenges 挑战
Health 健康
Effects on gilt flow 母猪群流动的影响
No direct control over gilts at puberty age在成熟期没有对后备母猪直接的控制
Off-site isolation and acclimatization场外的隔离和驯化
Lack of space for puberty management没有空间进行成熟期管理
Pressure for breeding targets (short term)配种目标的压力(短期)
