Sows are the most important of the farms, and the quality of the sows will directly affect the efficiency of the farm. What we pigmen need to do is to give the best management of the sows so that they can grow healthily, produce more piglets, and reduce the production costs of the farms.
1. The first step is to determine as soon as possible whether the sow is pregnant after mating. The sooner the determination is, the better. Pregnancy is strictly in accordance with the care of pregnant sows, not in time to analyze the reasons for pregnancy. See if estrus occurs 18-23 days or 34-44 days after mating. If there is no estrus and no other abnormalities occur, pregnancy is confirmed. Pregnancy can also be confirmed by B-ultrasound. The accuracy rate is as high as 95%.
It is also possible to anticipate sows earlier by empirical observation. Pregnant sows are generally tired, greedy, have increased food intake, are docile, slow-moving, and shiny. The upper swift vulva bends upwards and the estrus is no longer estrous for about 21 days. It is also possible to 3-4 days after mating, pinch the pig's final nipple and if it touches a harder milk duct, it indicates pregnancy. Early pregnancy test paper test is also a good method, take the morning urine 5ml according to the instructions can be tested. Finger pressure method: After 4 days of breeding, use the index finger 9-2 thoracic midline of the thumb index finger. If there is a depression, it is not pregnant. If there is no depression or bulge, it is very likely to become pregnant.
2. After sowing, the sow will be adjusted to the limit bar to reduce the activity. The fighting behavior of the large group of herders will be prevented from affecting the sow's fetus within one month of pregnancy. 8-16 days after mating is the critical period for embryo implantation, and management should be strengthened to reduce the movement and provide materials. In the later period, it will be raised in large circles to strengthen the exercise to avoid the sow's inability to produce, and at the same time, the sow's useful life will also be improved.
3. Pregnant sows are fed.
Immediately after mating, you can change to your own gestational material. You can configure it yourself or you can buy it directly. If you configure yourself, you must strictly control the feed ingredients. Pre-pregnancy: 30 days before mating, the sow can easily cause embryos if it feeds too much. death. Feeding volume should be controlled at 1.9-2.3 kg during this time. In particular, the amount of feeding should not exceed 1.5 kg per day within seven days of mating; Mid-pregnancy: Mainly attention should be paid to the sow's size management, adjusting the sow's body type, appropriately reducing the feeding amount of overweight, and increasing the amount of underweight. Volume, the average intake of 1.8-2.3 kg control; late pregnancy: breast development, is the full development of the breast 1.9-3.0 kg. Pregnancy sows generally begin to replace breastfeeding materials within 85 days after mating, and feed intake is about 3 kg; at the end of pregnancy, continue to increase feeding, fetal weight increases rapidly at this stage, 70% of fetal birth weight is completed one month before delivery of. Based on the original feeding amount, the feeding amount was increased by 3.0-3.5 kg; 5-7 days before delivery, the feed intake was appropriately reduced, postpartum constipation was reduced, mastitis was observed, and postpartum anoxia was observed. No feed was given on the day of production. From the second day after childbirth, the sow’s supplemental feed intake was slowly increased until normal intake.
4, pregnant sows constipation prevention: pregnant sows are very prone to constipation, can reach 50%. Add crude fiber to the feed and add baking soda to your drinking water. Minor constipation, appropriate increase in drinking water, add baking soda in water, strengthen exercise, etc. can be resolved, if serious constipation, you need to use Kai Sai Lu, vegetable oil enema methods to solve.
5, feed and drinking water: sows generally do not easily change the feed, but can not feed moldy feed. Especially in the sow stage of pregnancy to avoid. Drinkers drink plenty of water, through the flow control, up to 2 liters per minute, the water temperature is controlled at 16-20 degrees, the pighouse temperature is controlled at 16-20 degrees. Pregnant sows have stricter temperature requirements.
6, drug contraindications: This is very important, in strict accordance with the instructions for use, pregnant animals must not be used to disable, such as dexamethasone, streptomycin and so on. Antipyretic drugs should not be arbitrarily increased according to the dose.
7. Immunity during pregnancy: The immunization program does not perform well. Commonly weak and stillbirths, and poor health of newborn piglets. In order to ensure that piglets have sufficient maternal antibodies, the general vaccine can be used during pregnancy, such as: swine fever, pseudorabies, foot-and-mouth disease, JE, etc., but the immunization time should be one month after mating and one week before birth. The time period, and the injection of light, reduce stress, prevent mechanical abortion.
8, during pregnancy, health care, if there is no abnormality during sow pregnancy, then try to reduce medication, try to control the sow health from the nutrition and environmental management, for some sow farms more inflammation, postpartum lochia endless, sows Severe pig farms, such as diarrhea and piglet diarrhea, can be treated with lignomycin or amoxicillin for one week before delivery.
9, deworming: sows should be deworming two weeks before birth, to prevent mother-to-child transmission, reduce the incidence of neonatal piglet coccidiosis. At the same time, it can also remove the immunosuppression caused by coccidiosis. If the coccidia is more serious, you can use a drug named Baiqingqing, which is more effective. In addition to ivermectin spices for a week, to the coccidia is better, not valid for other parasites, but also should be combined with albendazole and so on. After deworming, we must remember to clean the barn to prevent re-infection.
10 Washing the upper part of the bed: Generally, pregnant pigs should be allowed to enter the disinfected delivery room for 7 days before delivery to adapt to the environment of the delivery room. However, before entering the delivery room, body sprays should be used for disinfection, scrubbing, and the cleanliness of the sheds and pigs should be guaranteed.
11, in addition need to pay special attention to, whether in the limit column, or in the large circle feeding must pay attention to the ground slip, slipping the sow is very unfavorable to the fetus.
12. Observe the status of the pigs, observe the feeding materials during the feeding, observe the defecation when cleaning the stools, observe the walking status while exercising, and observe the breathing conditions in the lounge. Only timely observation and timely diagnosis and treatment can maximize the time. Limit the loss.
