Key Points of Sow Breeding Technology and Feeding Management Methods
AbstractEnvironment: around 16-22 degrees, with humidity of about 70% to 80% being more suitable. Feeding: about 20 days before mating and about 10 days after mating, the feed amount needs to be increased; one week before farrowing, the feeding amount should be reduced by 10~20%. Farrowing: try to let sows farrow during the day, so as to carry out effective assistance. Keeping warm: in winter, warm materials such as straw need to be placed in the pigpen. Prevention and control: during the breeding period, they are prone to blue ear disease, which can cause sow infertility and miscarriage, so special attention is needed.
In recent years, the scale of pig farming has become larger and larger. Sows are very important to farms, but raising sows also requires certain skills. Feeding management must be strengthened, the temperature must be kept between 16 and 22 degrees, humidity must also be kept within a certain range, and feeding must be scientific, with the amount of food increased according to the situation. Doing a good job in cold protection and warmth preservation, and disease prevention are all very important.
Sow Breeding Technology
1. Strengthen feeding management. The temperature of the pigpen should be kept between 16 and 22 degrees, humidity should be 70% to 80%, and then feeding should be scientific and the hygiene of the pigpen should be maintained. Only in this way can the health of sows be ensured, thereby reducing the probability of embryo death.
2. Feed appropriately. After a sow becomes pregnant, within 9 to 13 days it will die due to the influence of some factors, and this is also a peak period of death for sows. The third day after pregnancy is the second peak period. Usually the third peak period is 60 to 70 days after mating, and during these periods special care must be taken in feeding sows. Usually, the amount of feed needs to be increased 20 days before mating and on the 10th day after mating. Wait until the condition recovers, then green feed can be the main food and feeding can be carried out according to normal standards. After 80 days of pregnancy, more concentrate can be fed, and some protein and minerals can also be added to the feed so that nutrition can keep up. One week before farrowing, the feeding amount of sows should be reduced by 10~20%.
3. Try to farrow during the day. Basically, most sows choose to farrow at night, but farrowing at night creates many difficulties. Many farmers, due to poor management at night, experience piglets being injured, disabled, or dying. If sows can be made to farrow during the day, this is conducive to monitoring, and the farrowing situation of sows can be observed at any time so as to assist farrowing. In this way, the survival rate will increase. Cloprostenol can also be used to assist sows in farrowing. This drug has the effect of dissolving the corpus luteum and can make the survival rate of farrowing reach 95%, with no side effects.
4. Do a good job in cold protection and warmth preservation. In winter, the temperature is usually relatively cold. At this time, warmth preservation work needs to be done well, and a large amount of warmth preservation materials, such as straw, need to be placed in the pigpen. If it is a farrowing sow, then its farrowing room must be kept relatively dry, with 65% to 75% humidity and a temperature of 22 to 23 degrees. Sunlight needs to shine in during the day. Use caustic soda water to disinfect the pigpen at any time, and a 20% quicklime solution can also be used to whitewash the walls, which can play a certain disinfection role.
5. Prevent and control diseases. For sows, the most common is blue ear disease during the breeding period. This disease is caused by the rabies virus and can cause sow infertility and miscarriage. Therefore, usually in this situation, we need to do a good job in defense work. The main measures are isolation and disinfection in daily life, ensuring the cleanliness and hygiene of the pigpen. The most important thing is to vaccinate pigs regularly and on time. Generally, for this disease, when sows are ten weeks old, they first need to be vaccinated with swine pseudorabies attenuated vaccine or genetically engineered vaccine. At the 14th week of age, a second vaccination is needed. Then after six months, vaccination is needed once every four months. Only in this way can it be prevented and treated.
Through the introduction above, do you have some understanding of sow breeding? It can be said that farrowing by sows is a major event. Sows during the breeding period are especially fragile. If they can be taken good care of during this period, the economic benefits will naturally follow.
