1. Adhere to raising a hybrid pig Hybrid pigs have strong vitality, rapid growth, and good feeding effects. It is necessary to popularize the "three-ization" new technology of boar improvement, localization of sows, and hybridization of piglets. 2. Adhere to fed compound feed According to the nutritional needs of pigs at different stages of growth, they insist on using full-priced compound feeds, and their nutrition is comprehensive without waste. 3. Change Hanging Fattening to Straight Line Fattening The traditional hanging shelf fattening is to divide the fattening period of the pig into several stages, and according to the needs of each different stage, the crude fat is combined with the roughage feed to fertilize. This method has a single feed and nutrition is not comprehensive, can not meet the pig's growth needs, pig growth is slow, the slaughter rate is low. If the straight-line fattening method that improves the nutritional level of piglets after weaning to pigs before slaughter, can effectively shorten the fattening period, increase the slaughter rate and increase economic efficiency. 4. Widely use auxiliary feed The treated distiller's grains, chicken excrement, rabbit feces, etc. are mixed with the feed and fed to the pigs together. The pigs love to eat, have long pods, have fast weight gain, and are slaughtered early, which can reduce 1%-3% of the pig raising costs. 5. Self-cultivation Owning excellent boars and breeding sows, breeding their own hybrid piglets and breeding their own pigs will help prevent epidemics, improve the survival rate of piglets, and help reduce costs. 6. Pushing high density pigs In the winter of 0.8 square meters, pigs are reared with 1 finishing pig, and 1 square meter in the summer raises 1 finishing pig. The high-density pigs not only have fewer establishment cycles, but also have low costs, and the finishing pigs compete for food. In the absence of a venue, pigs sleep when they are full, increase weight quickly, and reduce feeding costs. 7. Benefit to technology Promote one-stop rapid pig raising. Implementation of "five changes": a change in fat-raising pigs for Changbai, Yorkshire, Duroc and other lean-type pigs; two to feed a single feed for full-priced feed; three to feed "longevity pigs" for timely slaughter, proper feeding Feeding additive auxin; four changes of cooked feed for raw material wet feeding; five changes to sick veterinarians for disease-free early prevention, strict control of swine fever and other infectious diseases, improve the survival rate, slaughter rate. 8. Timely slaughter and slaughter After over 90 kilograms of fattening pigs, the rate of daily gain was significantly slowed down, and fat deposition was the main factor. Less than 90 kg slaughtered, although the feed utilization rate is high, but the meat rate is low because of the small body weight. The most suitable finishing pigs are 90-110 kg slaughter. Timely slaughter is directly related to the growing weight, feed-to-meat ratio and production cost of pigs during the fattening period. Therefore, when the live pig weight reaches 90-110 kilograms, it should be promptly slaughtered. Pig-raising pigs must be bred for “Three-Yuan†cross-breeding pigs. It is best to use Changbai and Yorkshire pigs with long waist, wide chest, short mouth, full hips, thick limbs, and food and food. Only about 160 days weight can reach 90-100 kg, can shorten the fattening period of 20-50 days.
