Adhering to breeding hybrid pigs of improved breed pigs Pigs such as Duroc, Hanshapu, Changbai and other boars and local sows are called hybrid pigs. Its ability to live strong, rapid growth, good feeding effect. Therefore, large-scale finishing pigs should generally promote the breeding of boars, localization of sows, and hybridization of piglets. Adhering to Feeding Compound Feeds According to the nutritional needs of pigs in different stages of growth, a variety of raw materials are mixed together to make a full-priced formula feed to pigs, which is not only nutritious, comprehensive, but also extremely wasteful. Implementation of protective feeding in summer and autumn outside the pig house should be planted gourd, sunflower and other plants shading cool; winter is to promote the use of plastic greenhouse breeding new technology, and regularly do a good job of insecticide and immune injection. Changing Hanging Frames into Finishing Lines Traditionally, hanging frames are used to divide the pig's fattening period into several stages, using various combinations of roughage and fattening. This method uses only a single feed, nutrition is not comprehensive, can not meet the needs of pig growth, so the pig feeding cycle is long, the slaughter rate is low. For pigs after weaning to slaughter pigs before slaughter, a straight-line fattening method that improves nutrition levels can effectively shorten the fattening period and increase economic benefits. Supplying sufficient clean water in the absence of water will affect the appetite of the pigs, affect digestion and normal growth, thereby reducing pig feed utilization. Widely used auxiliary feeds use brewers' grains, chicken excrement, and rabbit excrement. After processing, mixed feeds are added to feed the pigs. The pigs are very fond of eating, have fast weight gain, and are slaughtered early. Feeding pigs with supplementary feeds can reduce the cost of raising pigs by 1% to 3%. Self-bred and self-supported breeding of excellent husbandry and sows, adopting their own breeding pigs, cultivating their own cross-breed pigs, and rearing their own pigs for pigs without going outside to purchase piglets that are unclear and have no end in mind, are not only beneficial to epidemics, but also improve piglets The survival rate will also help reduce the cost of raising pigs. To implement a high-density pig raising 0.8 m2 in winter, pigs should raise a fattening pig, because of the dense, save the pigskin, reduce the investment in fixed assets, high-density breeding feed you grab him, after eating a small place to sleep and sleep, The weight gain is fast, the feeding period is shortened, and the feeding costs are reduced. To promote the science and technology to promote the “one-stop” rapid pig raising law and implement the “five reforms”, namely: to change the fat type pigs to lean type pigs such as Changbai, York, and Duroc; secondly to feed single feeds for feeding with the full price Feed; Three to feed clinker for raw and wet feed; Fourth change to feed “longevity pig” as timely delivery of “March pig” and “April pig” and reasonably feed additives and auxin; Anti-epidemiology seeks veterinarians for illness, early disease-free prevention, strict control of swine fever, swine erysipelas, swine plague, and paratyphoid fever, reduces mortality, improves survival rates, and stabilizes slaughter rates. After timely slaughter and slaughter of over 90 kilograms of fattening pigs, the rate of daily weight gain was significantly slowed down, and fat deposition was the dominant factor, so the more unfavorable it was to feed, the more fat would increase and the market would not sell well. Pigs slaughtered at less than 90 kilograms were not high-weight and had low meat rates and were not economically worthwhile. For finishing pigs, slaughter between 90 kg and 120 kg is most suitable.
