When is it appropriate for sows to start breeding?

Sows can conceive and give birth after sexual maturity, but they can't breed immediately. Because after the sow is sexually mature, it will continue to grow and develop for a period of time before reaching physiological maturity. If you breed immediately after sexual maturity, sows will not only have fewer litters and more stillbirths, but also their newborns will be small in weight, weak and slow in growth, which is also unfavorable to their own growth and development. However, farming too late will cause economic losses. Generally speaking, the most suitable mating age for sows should be after sexual maturity, before physical maturity, and when sows are in estrus for the third time. Large pig breeds, such as Landrace, Large White, Duroc, Hampson and so on. It can be bred at the age of 9 months, and its weight is 120 ~ 130 kg. Yorkshire, Bakersfield and other medium-sized pig breeds can be selected when they are 10 months old and weigh 100 ~ 125 kg. Local pig breeds should be adjusted according to estrus sooner or later. Generally, they are most suitable for breeding when they are 6-8 months old and weigh 60-70 kg.
