In general, the feeding strategy for pregnant sows follows a "low before high" principle. During the early stages of pregnancy, sows should be fed low-energy diets to prevent excessive weight gain and reduce the risk of embryo loss. This includes increasing the proportion of roughage in their feed one month before conception. For lean-type pigs, if using complete feed designed for pregnant sows, it's important to control the daily intake: keep it below 1.8 kg during the first 30 days after mating, increase to 2 kg between 80–85 days of gestation, and then raise it to 2.2–2.5 kg per day in the last month before farrowing. One week before birth, the feed can be switched to lactation sow feed, with daily amounts gradually increased to 3–4 kg. It’s also advisable to adjust feeding levels a day or two before farrowing to ensure adequate nutrition for both the sow and her developing piglets.
The feeding amount should always be adjusted based on the individual condition of the sow and the nutrient density of the feed mixture. Regular monitoring of body condition helps determine whether the feed needs to be increased or reduced. A well-balanced diet ensures that the sow remains healthy and can provide sufficient nutrients for her litter’s growth and development. Proper feeding not only supports the health of the sow but also improves the survival rate and growth performance of the piglets.
Feed management is a critical aspect of swine production, and understanding the specific nutritional requirements at each stage of pregnancy can significantly impact overall productivity and profitability. By following these guidelines, farmers can optimize feed efficiency and improve reproductive outcomes.
