(1) It is an important content to reduce the cost of raising pigs by adopting comprehensive technology, improving management level and transforming science and technology into productivity. The comprehensive technology of pig production mainly includes advanced production management technology and epidemic prevention technology. Judging from the current situation, it is the main aspect to increase the income of pigs to have more babies, grow fast and have good meat quality and reduce the loss of epidemic diseases. In the environment of market competition, large-scale commodity production will be difficult to survive without adopting advanced technology and improving management. Therefore, we must vigorously promote the advanced technology of pig production and disease prevention and control, and apply comprehensive technology to reduce costs and increase profits.
(2) Increasing product quantity, improving product quality and reducing consumption are interrelated and must be considered comprehensively. Therefore, it is necessary to: ① raise improved pigs and increase the litter size of sows; ② Shorten the lactation period of piglets; (3) Properly arrange the turnover of pigs and make full use of piggery and equipment; ④ Control the feeding cycle of fattening pigs, and the maintenance needs of pigs are usually related to their weight. Growing pigs weighing 60kg need to consume 26.75mJ of metabolic energy every day, of which more than 60% is consumed in synthesis and only 40% is converted into products. Therefore, the shorter the feeding cycle, the higher the economic benefit. Moreover, fat pigs weighing more than 100 kg have high fat content, are unpopular and have low prices; ⑤ Improve meat quality; ⑥ Scientific feeding management can effectively exert the production potential of improved pigs.
(3) The main measures to increase income and reduce expenditure: ① Artificial insemination, the cost of purchasing semen is only about 10% of the cost of breeding boars; (2) Try to reduce feed costs, not to feed pigs less, but to raise them scientifically. Therefore, we should use full-price compound feed, try to use cheap and good feed substitutes, try to make our own feed or use local feed to raise the feed well; Beware of mixed feed; Reasonable design of feed trough to prevent feed waste. ③ Improve work efficiency and minimize labor costs; (4) Improve the utilization rate of houses and pig-raising equipment; ⑤ Minimize the medical and health expenses for epidemic prevention; ⑥ Reduce utilities, transportation fees and enterprise management fees.
(4) Other measures, such as improving the microclimate environment in the pigsty; Comprehensive utilization of pig manure and biogas; Develop ecological animal husbandry, etc. All these can improve the economic benefits of pig farms.
