Feeding pregnant materials can be configured or purchased directly. If configured, feed raw materials must be strictly controlled. Early pregnancy: from mating to 30 days before pregnancy, sows eat a lot and are prone to embryo death. During this period, the feed should be limited to 1.9-2.3 kg. Especially within 7 days after breeding, the daily feeding amount should not exceed 1.5 kg.
The last three months: mainly pay attention to the management of sow body shape, adjust sow body shape, reduce the feeding amount for obese people, increase the feeding amount for underweight people, and control the average feed intake at1.8-2.3 kg; The third trimester of pregnancy: the mammary gland develops, which is 1.9-3.0 kg of fully developed mammary gland. Generally, pregnant sows start to change breast feed 85 days after mating, and the intake is about 3 kg. In the third trimester of pregnancy, the feeding amount continues to increase, and the fetal weight increases rapidly at this stage. One month before delivery, the fetal weight reached 70% of the birth weight. On the basis of the original feeding amount, the feeding amount is increased by 3.0-3.5 kg; 5-7 days before delivery, reduce the feed intake appropriately to reduce postpartum constipation, mastitis and postpartum mammary gland hyperplasia. No feed was given on the day of birth, and the amount of supplementary feeding for sows was gradually increased from the second day after birth until normal feeding.
Water management sows generally do not refuel easily, not to mention moldy and deteriorated feed. Especially pregnant sows should avoid this situation. The water dispenser is filled with water, the flow rate is controlled at 2 liters per minute, the water temperature is controlled at 16-20 degrees, and the pigsty temperature is controlled at 16-20 degrees. Pregnant sows have stricter requirements on temperature. Do a good job in immunization procedures to avoid the common problems of weak fetus, stillbirth and poor health of newborn piglets. In order to ensure that piglets have enough maternal antibodies, common vaccines can be used during pregnancy, such as classical swine fever, pseudorabies, foot-and-mouth disease and Japanese encephalitis. However, the immunization time should be avoided 1 month after mating and one week before delivery, and the injection should be light to reduce stress and prevent mechanical abortion.

Prevention of constipation pregnant sows are prone to constipation, which can reach 50%. Add crude fiber to feed and baking soda to water. Mild constipation can be solved by increasing drinking water, adding baking soda to water and strengthening exercise. If constipation is serious, you need to use methods such as kaisailu and vegetable oil enema. Deworming program Sows should be deworming once two weeks before delivery to avoid mother-to-child transmission and reduce the occurrence of coccidiosis in newborn piglets. It can also alleviate the immunosuppression caused by coccidiosis. If coccidiosis is serious, you can use a medicine called Bethune, and the effect is better. In addition, ivermectin mixed for a week is good for coccidia, but ineffective for other parasites, and should also be used in combination with Bethune. Remember to clean the pigsty after deworming to prevent reinfection.
The above are the main points of daily management of pregnant sows. If your sow is pregnant, you should pay more attention to these aspects. Of course, health care during pregnancy and preparation for delivery are also very important.
