What is the ideal age range to delay breeding for gilts to achieve the best natural immunity?

The ideal age range for delaying breeding in gilts to achieve the best natural immunity is 7.5 to 8 months. This timeframe allows gilts to reach a better state of physical and reproductive maturity, which is crucial for enhancing their immune responses. By delaying breeding until this age, gilts can develop stronger immune systems, which helps them resist diseases and infections during and after pregnancy. This stage also allows for optimal development of the reproductive organs, ensuring healthier litters and better overall productivity.

Breeding too early can compromise the gilt's health and immune system development, potentially leading to increased stress and vulnerability to diseases that can affect both the gilt and future piglets. In contrast, delaying breeding beyond this optimal age can also lead to diminishing returns as there may not be significant additional benefits in terms of immunity. Thus, the age range of 7.5 to 8 months strikes a balance between mature health and reproductive capability in gilts.
