Daily feeding and management of pregnant sows

Sows are the top priority of pig farms, and the quality of sows directly affects the efficiency of pig farms. What we pig farmers have to do is to give the best management to sows, so that they can grow healthily, produce more babies, and reduce the production cost of pig farms.

1. First of all, whether the sow is pregnant after mating should be determined as soon as possible, the earlier the better. Pregnant in strict accordance with the care of pregnant sows, not pregnant timely analysis of the reasons. Check estrus 18-23 days or 34-44 days after mating. If there is no estrus and no other abnormal conditions occur, it means pregnancy. Pregnancy can also be confirmed by B-ultrasound, with an accuracy of 95%.

In addition, the pregnancy of sows can be predicted in advance by empirical observation. Pregnant sows tend to be tired, sleepy, meek, slow-moving and shiny. Get fat fast vulva bend upward, mating 21 days or so no longer oestrus to determine pregnancy. You can also pinch the pig's nipple with your hand 3-4 days after mating, and if you touch a hard milk duct, it indicates pregnancy. Early pregnancy test paper test is also a good method, take morning urine 5ml according to the instructions can be tested. Finger pressure method: 4 days after mating with the thumb index finger 9-2 thoracic vertebrae back midline, if there is a depression is not pregnant, if there is no depression, or protuberance, it is very likely to be pregnant.

2. After mating, the sows will be adjusted to the limit column, in order to reduce activities, prevent and control the fighting behavior raised in large groups will affect the sow fetus to achieve no conversion within one month of pregnancy, no vaccination, and reduce stress. 8-16 days after mating is the critical period of embryo implantation, so we should strengthen management, reduce exercise and feed tailor-made. In the later stage, it can be raised in a large circle to strengthen exercise, so as to avoid the weakness of sow production and improve the utilization life of sows at the same time.

3. Pregnant sows were fed.

First of all, immediately after mating, it can be changed to pregnancy material, which can be configured by itself or purchased directly. If you configure it yourself, you must strictly check the feed raw materials; pre-pregnancy: from mating to 30 days before pregnancy, if the feed intake of sows is large, it is easy to lead to embryo death. During this period, the amount of feed should be controlled at 1.9-2.3 kg. Especially within 7 days of mating, the daily feeding amount should not exceed 1.5 kg; in the second trimester of pregnancy, attention should be paid to sow shape management, regulation of sow shape, appropriate reduction of feeding for those who are overweight, and appropriate increase in feeding for those who are underweight, the average feed intake should be controlled at 1.8-2.3 kg; in the third trimester of pregnancy, the full development of mammary glands is 1.9-3.0 kg. Pregnant sows generally begin to change lactation feed 85 days after mating, with a feed intake of about 3 kilograms; at the end of pregnancy, continue to increase feeding, at this stage fetal weight increases rapidly, 70% of fetal birth weight is completed in one month before delivery. On the basis of the original feeding amount, increase the feeding amount, 3.0-3.5 kg; 5-7 days before delivery, appropriately reduce food intake, reduce postpartum constipation, mastitis, postpartum non-breast disease. The sows were not fed on the day of delivery, and the feed intake of sows was gradually increased until the normal intake on the second day after delivery.

4. Constipation prevention of pregnant sows: pregnant sows are very prone to constipation, up to 50%. Add crude fiber to feed and baking soda to drinking water. Mild constipation can be solved by properly increasing drinking water, adding baking soda and strengthening exercise. If constipation is serious, it is necessary to use Kaisailu, vegetable oil enema and so on.

5, feed and drinking water: sows generally do not easily change feed, but also can not feed moldy and deteriorated feed. Especially in the stage of pregnant sows, try to avoid. Adequate drinking water in the drinking fountain, up to 2 liters per minute through flow control, the water temperature is controlled at 16-20 degrees, and the temperature in the pigsty is controlled at 16-20 degrees. Pregnant sows have strict temperature requirements.

6, medication taboos: this is very important, in strict accordance with the instructions, pregnant animals must not be used, such as dexamethasone, streptomycin and so on. Antipyretic drugs should be used according to the dose and should not be increased at will.

7. Immunity during pregnancy: weak fetus and stillbirth are common in poor immune program, and the health status of newborn piglets is poor. In order to ensure that piglets have sufficient maternal antibodies, general vaccines can be used during pregnancy, such as classical swine fever, pseudorabies dogs, foot-and-mouth disease, Japanese encephalitis, etc., but the immune time should avoid one month after mating and one week before parturition, and the injection action is light, reduce stress, prevent and cure mechanical abortion.

8. health care during pregnancy, if there is no abnormality in sows during pregnancy, try to reduce the use of drugs and control the health of sows from nutrition and environmental management as far as possible. for some pig farms with more sow inflammation and postpartum lochia, sow diarrhea, piglet diarrhea and other more serious pig farms, you can add ligomycin or amoxicillin in the feed for a week before delivery.

9. Deworming: sows should be dewormed once two weeks before birth, which can avoid mother-child transmission and reduce the incidence of coccidiosis in newborn piglets. At the same time, it can also relieve the immunosuppression caused by coccidiosis. If coccidiosis is more serious, a drug called Baiqiuqing can be used, which is more effective. In addition to ivermectin mixing for a week, it is better to get rid of coccidiosis, but it is ineffective to other parasites, and it should also cooperate with Albendra. Be sure to clean the pigsty after deworming to prevent re-infection.

10 cleaning on the delivery bed: generally 7 days before delivery, pregnant pigs should be allowed to enter the sterilized delivery room to adapt to the environment of the delivery room. But before entering the delivery room, the whole body should be sprayed and scrubbed, and the cleanliness of the barracks and pigs should be ensured at ordinary times.

11. in addition, we should pay special attention to the fact that no matter in the limit bar or in the large circle, we must pay attention to the ground anti-skid, the sow slip is very disadvantageous to the fetus.
