Sow breeding technology

Environment: at about 16-22 degrees, the humidity is about 70% to 80%. Feeding: about 20 days before mating and 10 days after mating, the amount of feed should be increased, and the amount of feed should be reduced by 10% to 20% in the week before production. Give birth: let sows give birth during the day as far as possible, so as to provide effective assistance. Keep warm: keep warm materials such as straw in the pigsty in winter. Prevention and control: it is easy to suffer from blue ear disease during the breeding period, which will cause infertility and abortion in sows, which requires special attention.

In recent years, the scale of raising pigs is getting larger and larger, and sows are very important for farms, but sows also need certain skills, and the management of sows must be strengthened to keep the temperature between 16 and 22 degrees Celsius. Humidity is also maintained in a certain range, and scientific feeding, according to the situation to increase food intake, do a good job of cold protection, warmth, disease prevention work, these are very important.

Sow breeding technology

1. To strengthen feeding management, the temperature of the pigsty should be kept between 16 and 22 degrees, and the humidity should be 70% to 80%. Then feed scientifically and keep the pigsty hygienic, so as to ensure the health of sows and reduce the chance of embryo death.

2. proper feeding, when the sow is pregnant, it will be affected by some factors within 9 to 13 days, that is, a peak of death in the sow, and the third day after pregnancy is in the second peak period. usually the third peak period is 60 to 70 days after mating, and these periods should be especially careful in feeding sows, usually 20 days before mating and 10 days after mating. When the situation is restored, green fodder can be used as the main food, fed according to the normal standard, and more concentrate can be fed after 80 days of pregnancy, and some protein and minerals can be added to the feed, so that nutrition can keep up. In the week before production, the feeding amount of sows should be reduced by 10%.

3. Try to give birth during the day. Basically, most sows will choose to give birth at night, but there will be a lot of difficulties in giving birth at night. Because of poor management at night, there will be disability or death of piglets. If the sows can give birth during the day, this is conducive to monitoring, can observe the situation of sows giving birth at any time, and thus carry out auxiliary birth, so that the survival rate will be improved. Chloroprostol can also be used to assist sows in giving birth. This drug has the effect of dissolving corpus luteum and can make the survival rate of litter reach 95% without any side effects.

4. Do a good job of preventing cold and keeping warm. The temperature is usually cold in winter. At this time, you need to do a good job of keeping warm. You need to put a lot of warm materials in the pigsty, such as rice straw. If it is a sow giving birth, it must keep its delivery room relatively dry. It has 65% to 75% humidity and a temperature of 22 to 23 degrees. During the day, the sun needs to come in and disinfect the pigsty with caustic soda water at any time. 20% quicklime solution can also be used to brush the fence, which can play a certain role in disinfection.

5. to prevent and control diseases, the most common disease for sows is blue ear disease during the breeding period, which is caused by rabies virus, which can cause infertility and miscarriage in sows, so usually in this case, we need to do a good job of defense. the main measure is to carry out isolation and disinfection in daily life to ensure the cleanliness and hygiene of the pigsty, and the most important thing is to nursery pigs on a regular basis. At the age of ten weeks, sows need to first breed pseudorabies attenuated vaccine or genetically engineered vaccine, and at the age of 14 weeks, they need to be vaccinated for the second time, and then after six months, they need to be vaccinated every four months in order to be prevented.

Through the introduction above, do you know something about sow breeding? It can be said that the birth of sows is a major event, and sows during the breeding period are particularly vulnerable. If they can be taken good care of during this period, the economic benefits will naturally come out.
