Adjust diets appropriately
Increase energy. In spring, the proportion of diet should be properly adjusted to improve the dietary energy level and reduce the protein level. Raw materials can be used for corn and oily materials, and less valuable materials such as bran, bran, and straw are used.
Increase palatability. The increase in feed intake can increase the resistance of pigs to low temperatures. Appropriate addition of oils to the diet can increase its palatability. For piglets, sweeteners have a good attractant effect.
Ensure vitamin intake. In order to prevent disease from occurring in spring pigs, it is necessary to supplement the body's vitamin levels by feeding certain green feed. For breeding pigs, a certain amount of multivitamins can be added to feeds; gilts that are rich in vitamin A and vitamin E can be fed more appropriately for gilts; iron supplements and selenium supplements should be done for piglets. Prevents anemia from affecting its growth.
Focus on the choice of feeding methods
Feeding is scientific and reasonable. In response to the nutritional needs of sows at different times, the feeding of pregnant sows varies from pig to pig. In the production, the following three methods are commonly used: For poorly sown sows, 20 days before breeding and breeding After 10 days, the concentrate was fed. After the body condition was restored, it was mainly fed with green fodder. Feeding was carried out according to the feeding standard until 80 days after the pregnancy, and the concentrate was fed again, but the nutritional level in the later period should be higher than the previous period. For pre-breeding sows with good pre-planting status, green roughages can be fed more in the first trimester of pregnancy and fine concentrates can be added later. For the sows that are born and the sows that are bred during lactation, it is advisable to use the green roughage in the early stages of pregnancy to gradually increase the proportion of concentrate and increase the protein and mineral content in the feed. However, care should be taken to reduce the diet by 10% to 20% in the week before the sow is born.
Supply mothers adequate nutrition
Satisfying the supply of nutrients is necessary to ensure the normal growth and development of sows and fetuses. The nutrients obtained from the diets of sows are first of all to meet the needs of the growth and development of the fetus before they supply themselves and provide nutrition for breastfeeding. In addition to supplying the energy and protein feed needed in the growth of the sow, it should also meet the needs of minerals and vitamins to avoid a single feed and affect the normal growth and development of the mother and child.
Regular quantitative feeding
The rations fed to pregnant sows should be scientifically and rationally formulated according to their nutritional needs. Attention should be paid to hygiene and quality assurance. It is forbidden to feed moldy, frozen, poisonous, and irritant feeds, otherwise it is easy to cause miscarriage; Feel free to change feed types. Feeding green roughage should be less frequently fed, regularly quantified, and can guarantee that the sow can drink clean drinking water at any time.
Effectively strengthen feeding management
The focus of management of pregnant sows is to do a good job. In production, firstly, the first month of gestation should be eaten well, sleep well, and exercise less. One month later, exercise should be done as much as possible. Every day should be kept for 1 hour to 2 hours. It is better to combine grazing. Second, it is not good. The weather must stop exercising to cause a miscarriage due to the non-slip or severe contraction of the uterus caused by stress. Third, whipping and ankles are strictly prohibited. Crossing over the ditch should be slow, preventing crowding and rapid eviction and sharp turning. Fourth, the amount of exercise should be reduced in the middle and later stages of pregnancy. Let the sow move freely. The activity should be stopped one week before childbirth. The fifth is that the sow must be raised in a single lap in the later period of pregnancy. Sixthly, it is necessary to take measures for treatment and timely injection of progesterone to prevent miscarriage.
