After the sow is pregnant, there are three special periods that can easily cause embryonic death. The first one is 9 to 13 days. At this time, the fertilized egg starts to come into contact with the uterine wall and is ready to implant. It has not yet been implanted. If the uterine environment is disturbed, it is the most likely to cause death. The number of deaths at this stage occupies the total number of embryos. 20% to 25%. The second is 18 to 24 days. At this time, embryonic organs are formed. In the process of escaping the secretory substances of the blastoderm, the weak person dies. The number of deaths at this stage accounts for 10% to 15% of the total number of embryos. The third is 60-70 days. At this time, the blastoderm ceases to develop, and the fetus develops rapidly. Insufficient nutrient supply can cause embryonic death. The number of deaths at this stage accounts for 5% to 10% of the total number of embryos. Sow Pregnancy Pregnancy Measures: 1. Keep quiet. During the period of embryonic lethality, if the sow is disturbed by a startled euphoria, resulting in a metabolic disorder, the intrauterine environment is inhibited and the number of embryonic deaths may increase. Therefore, during pregnancy, it is necessary to keep the shed quiet, avoid being close to strangers, prevent harassment of pets or small animals, prohibit strong noise, and do not rush, sow the sow, and ensure that the sow is free from any interference. 2. Strengthen management. Give pregnant sows good feed, mold, contamination, frozen feed, and silage as much as possible. In summer, the rate of mating and stillbirth is higher. It is necessary to control the small environment in the pig house. The temperature is 15°C to 25°C and the relative humidity is 70% to 80%. 3. Control the amount of feed. After sows, the sows become very quiet and their feed intake increases rapidly. If they are allowed to eat freely, body lice will increase rapidly, easily resulting in stillbirths or causing dystocia. During the first trimester (within 21 days after mating), the daily feed amount is 2 kg, the mid-gestation period (22-60 days) is 2.5 kg per day, and the third day of the pregnancy is 3 kg per day. It is advisable to maintain a net gain of 20 kg during pregnancy. 4. Drug miscarriage. Sows who are habitually aborted can give progesterone by intramuscular injection of 15 to 25 milligrams to the sow after about 7 days of mating. When it is found that there are signs of miscarriage, progesterone should be used to prevent miscarriage in time. The effect of TCM is better, 21 days after mating, use 20 grams of Codonopsis pilosula, Radix Astragali, Angelica, Dipsacus, Astragalus, Atractylodes, Amomum each, 15 grams of each of Chuanxiong and Lingcao, and add 100 grams of sticky rice after the decoction to the residue. The boiled porridge was fed to the sow, one dose per day for 2 days. 5. Prevent diseases. There are many infectious diseases that cause sows abortions and stillbirths, including swine fever, porcine reproductive and respiratory syndrome, pseudorabies, parvovirus, Japanese encephalitis, influenza, brucellosis, eperythrozoonosis, Leptospirosis, chlamydia, etc., the most common of which are parvovirus and Japanese encephalitis, must be well vaccinated. The parvovirus vaccine can be inoculated 2 to 4 weeks before the sow is bred. The male boar is vaccinated once every six months. The Japanese encephalitis vaccine is usually vaccinated from April to May. The first-born sow must be injected.
