First, raise the quality of piglets piglet quality has a great influence on the fattening effect. Practice has shown that piglets with a large weaning weight gain weight faster during the finishing period. Therefore, if you want to increase the weight of fattening pigs, you must first raise your suckling piglets. To prevent frostbite, prevent pressure, and set the nipples in the initial stage, artificially suckling should be carried out on individual weak piglets so that they can eat colostrum. After 3-5 days of birth, the piglets should be fed 2.5% of ferrous sulfate and 1% of them. Copper sulfate mixture prevents piglets from anemia. After 7 days, fry the feeds of corn slag, wheat, beans, and bone shell powder, etc., and fill them with mixed feed such as cornmeal, bean cake noodles and wheat bran flour. Supplementary feeds should insist on feeding the feed first, and then feeding it for a long time without water. During the day, the number of wet feedings was limited and dry powders were freely consumed at night. Second, timely castration piglets castration, eat more, long fast, and can eliminate odors. Castration is best performed at 25 to 30 days of age, castration as early as possible, piglets bleed less, knife healing faster, and little effect on growth. If castration after weaning, especially if the weight is too large before castration, the piglet bleeding, wound healing slow, easy to infect, have a great impact on growth. Third, timely weaned piglets generally weaned at 40 days of age. The original feed should be kept within 2 to 3 weeks after weaning and gradually changed to feed for weaned piglets. At least within half a month, they should be reared according to the feeding method of the suckling piglet, and keep the personnel, feed, and housing unchanged to promote the normal growth and development of the piglet. IV. Insect repellents The parasites are repelled within one month after weaning. The commonly used drug is deworming net (tetraimidazole), which is effective for repelling aphids in pigs. It uses 20 milligrams per kilogram of body weight, is fed into a small amount of feed, and can also be injected. Pig ectoparasite common rickets, can be used 1% aqueous solution of trichlorfon spray control, and strict disinfection of the pigs. After insecticide, the stomach must be given to the pig, which is conducive to the healthy growth of the pig. Fifth, to do a good job of prevention of disease can be piglets 20 to 40 days of age injection of swine fever, swine erysipelas, swine flu vaccine triple vaccine. To enhance immunity and ensure the safety of the fattening period. Inject again about 90 days old.
