First, we insist on raising hybrid pigs. 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. The second is to insist on feeding formula feed. According to the nutritional needs of pigs in different stages of growth, they insist on using full-priced compound feeds, which provide comprehensive nutrition without wastage, and lower meat and pork prices. The third is to implement protective feeding. In the summer and autumn season, plants such as gourds, big melons, follicles, sunflowers and other plants outside the pig house can be shaved and cooled. In winter, plastics greenhouse feeding technology is promoted, and insecticide and immunization are regularly performed. The fourth is to change the hanger to fatten a straight line. The traditional hanging shelf fattening is to divide the fattening period of the pig into several stages, and use the crude roughage in combination at different stages to fertilize. This method has a single feed, nutrition is not comprehensive, can not meet the growth needs of pigs, pig growth is slow, long feeding cycle, slaughter rate is low. If we adopt a straight-line fattening method to raise the nutritional level of pigs after weaning to pigs before slaughter, we can effectively shorten the fattening period, increase the slaughter rate, and increase economic efficiency. Fifth, supply sufficient clean water. Lack of water will affect the appetite, digestion, and normal growth of pigs, thus reducing the use of feed. Sixth, extensive use of supplementary feeds. Using processed brewers' grains, chicken excrement, and rabbit excrement to feed the pigs together in the mixed feed, the pigs are very fond of eating, are on the larvae, have fast weight gain, and are slaughtered early, which can reduce the pig raising cost by 1 to 3%. Seventh is 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. Eight is to promote 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. For high-density pigs, not only is the establishment of a small circle, but also the cost is low, and the finishing pigs compete for food. There is no activity space to sleep, love long meat, increase weight, reduce feeding costs. Nine is to benefit technology. Promote one-stop rapid pig raising. Implementation of "five reforms and one plus": a change in fat-raising pigs for Changbai, Yorkshire, Duroc and other lean-type pigs; two to feed a single feed for the formula full price feed; three to feed "longevity pig" as timely Slugging, and feeding additive auxin; four change cooked feed for raw materials wet feed; V change the disease to find a veterinarian for disease-free early prevention, strict control of swine fever, swine erysipelas, swine plague, paratyphoid fever four infectious diseases, Reduce the mortality rate, increase the survival rate and slaughter rate. Tens are slaughtered and slaughtered in due course. After 90 kg of fattening pigs, the rate of daily weight gain was slowed down, and fat deposition was the main factor. Therefore, the more unfavorable the feeding was, the more fat was increased and the sales were not good. In the case of less than 90 kg slaughtered, although the feed utilization rate was high, Because of the small body weight and low meat yield, it is not economical. Generally, 90 to 120 kg of slaughter pigs are the most suitable for slaughter. China Agricultural Network Editor
