What is the normal weight gain during gestation for sows?

During gestation, the typical weight gain for sows is around 30 to 60 pounds. This weight gain is important as it reflects the nutritional status and overall health of the sow, as well as the resources available for fetal development.

Weight gain during gestation comes from several factors, including the development of the fetuses, increased blood volume, and the accumulation of placental tissue and adipose reserves in the sow. Maintaining this range of weight gain is crucial for ensuring that the sow can support the growth of her piglets and have adequate metabolic reserves for lactation after farrowing.

When sows gain weight within this range, it indicates that they are receiving proper nutrition and are likely to have healthier litters. Conversely, inadequate or excessive weight gain can lead to complications for both the sow and her piglets, which underscores the importance of carefully managing a sow's diet and monitoring her weight throughout gestation.
