1. Adhere to the breeding of hybrid male boars, such as Duroc, Pietrain, Decca, Hampshire, Changbai, etc., and hybrid piglets produced by local boar sows, which have strong viability, rapid growth, and rearing. The effect is good. Therefore, the breeding households need to implement the “threeizations†technology of improved breeding of boars, localization of sows, and hybridization of piglets.
2. Insist on feeding compound materials According to the nutritional needs of different growth stages of pigs, feeds made from a variety of raw materials can be nutritionally comprehensive without waste, and the feed-to-weight ratio can be reduced.
3, the implementation of protective feeding summer and hot season can be outside the pig house planting gourd, grape, sponge gourd and other vines shade cooling, plastic greenhouses in winter to raise, regularly do a good job of insecticide and immune injection.
4. The traditional hanging shelf fattening method using straight fattening method is to divide the pig fattening period into several stages, and to use different ratios of crude roughage for fattening. This method has a single feed and nutrition is not comprehensive, can not meet the pig's growth needs, slow growth, long feeding cycle, and low slaughter rate. If the straight-line fattening method that raises the feeding level is adopted for the pigs after weaning the pigs until the slaughter, the fattening period can be effectively shortened, and the slaughter rate and economic efficiency can be improved.
5. Supply of sufficient water The lack of water can significantly affect the appetite, digestion, and normal growth of pigs, thereby reducing the use of feed. Some people think that the impact of water shortage on the pig may be more serious than the lack of material.
6, make full use of auxiliary feed will be mixed with bad beer in the mixed feed to feed pigs, pigs love to eat, easy to eat, fast weight, slaughter early, can reduce the cost of pigs 1 to 3%.
7. Implement the self-bred and self-sustaining method to breed fine male and female sows, adopt their own breeding pigs, breed their own hybrid pigs, cultivate their own commercial pigs, and not purchase piglets out of the country, which will help prevent epidemics and reduce the cost of raising pigs.
8, the use of high-density pig raising appropriate increase pig density, each finishing pigs accounted for 0.8 square meters in winter and 1 square in summer. The high-density pigs not only have fewer laps, but also have low costs. The pigs are rushing to eat and eat when they are fed. They can shorten the feeding period and reduce feeding costs.
9, the implementation of "five reform and one plus" pig raising a change of fat-raising pigs for Changbai, Yorkshire, Duroc and other lean-type pigs; two to feed a single feed for compound feed; three to feed cooked feed for raw materials Wet feeding; four changes to feed "longevity pigs" for the timely slaughter pigs; five changes to the disease to find veterinarians for the prevention of disease-free early prevention, to prevent various infectious diseases, improve the survival rate and slaughter rate. One plus feed additives, auxin and other fertilizer.
10. When timely slaughtering and slaughter of finishing pigs exceeds 90 kg, the rate of daily weight gain is significantly slowed down, and fat deposition is the main factor, so it is neither cost-effective nor easy to sell; and less than 90 kg slaughter slaughter, although feed utilization The rate is high, but due to the small body weight and the low rate of meat production, it is not economically worthwhile. In general, finishing pigs are best slaughtered at a weight of 90-120 kg.
