What causes sows to lose body condition after farrowing

1. Causes of body condition loss in sows after farrowing

1. Feed intake and weight loss in sows are negatively correlated;

2. Milk yield and weight loss in sows are positively correlated;

3. Weaning litter weight of piglets is positively correlated with weight loss;

4. Feed intake during gestation and feed intake during lactation are negatively correlated.

2. Measures to prevent body condition loss in sows after farrowing

1. In the early gestation period, simply feed the sow according to normal feed amounts. In the middle and late stages, do not increase the feeding amount just because the sow's appetite increases. If the sow becomes fat at this time, the fat accumulated in the body will not only affect the normal growth and development of the piglets in the womb, but will also cause the sow's feed intake to drop sharply after farrowing, leading to severe body condition loss and affecting milk production. Therefore, in the middle stage of gestation, feed 2.0-2.5kg/day as the standard, and in the late stage appropriately increase it to 3.0-3.5kg/day. Starting 40 days after farrowing, add 0.2% Youshenghuo peptide or 0.5% Shengmingyuan peptide to the feed, and appropriately add green fodder. This can both enhance the sow's gastrointestinal function and prevent constipation and refusal to eat, which can lead to insufficient reserves and affect postpartum feed intake.

2. Regarding reducing feed before farrowing, since the farrowing time of the sow cannot be determined, it is only necessary to reduce the meal before farrowing. If feed is reduced too early, it will cause the sow to consume energy too early and have no strength to give birth at farrowing time. Prolonged farrowing in sows will increase piglet survival rate and the number of weak piglets.

3. On the day of farrowing, the sow needs to be induced to eat. A wet mixed feed of brown sugar + warm boiled water + 0.2% Yinengchang peptide can be used. This not only helps the discharge of postpartum lochia in sows, but also effectively prevents piglet yellow and white dysentery caused by postpartum inflammation, increases feed intake and milk yield, avoids insufficient energy in sows during early lactation, and prevents severe body condition loss in sows from affecting milk yield and the natural estrus rate seven days after weaning.

4. In hot summer seasons, fish meal and oil can be added to feeding to increase the nutritional concentration of the feed.
