Strengthening scientific management, developing the scale of pig raising

With the rapid economic development and the improvement of people’s living standards, people’s health awareness and environmental awareness have gradually increased. The demand for meat food has shifted from the quantity demand to quality, safety, and health. In order to adapt to the development of modern agriculture, protect the people's health, and promote the sustainable development of the pig industry, it is necessary to abandon the rural absorptive habits, move toward scientific, large-scale, modernization, and take the road of large-scale farming.

Achieving large-scale pig rearing refers to the comprehensive use of farms, farm management, animal husbandry and veterinary science and technology to achieve a high-quality, high-yield management and breeding effect, and provide a large number of inexpensive commercial pork products. The scale of pig-raising operations is large, with a high degree of specialization and intensification. The pigs are growing and fattening rapidly, the turnover of slaughter is accelerated, the weight gain and material consumption are reduced, and the utilization rate of the pens is high.

Choosing good breeds Large-scale pig farms feeding lean-type pigs require more calving, faster growth, and less feed and adaptability. After practice in recent years, foreign pig breeds show extremely excellent characteristics. At present, the boars are mainly purebreds such as Dabai, Changbai, Duroc, and Pitlan. The sows use the above-mentioned purebred pigs or the above-mentioned binary crossbred sows to carry out dual-crossing and three-way hybrid production. Pigs and commercial pigs have high lean meat percentage, rapid growth and good feeding effect.

Adopt advanced production technology to create pigs suitable for pig breeding, growth and development of environmental conditions and feeding and management conditions in accordance with the different growth stages of pigs, the implementation of industrial production methods, staged breeding, stage littering, balanced production of pigs throughout the year. Phase-feeding methods are adopted, ie the sow's empty pregnancy phase, the sow's calving stage, the young pig breeding stage, and the fattening stage. Change the traditional rural free-standing habits and promote the scale, intensification and modernization of aquaculture production in the entire region.

The scientific breeding of pigs using large-scale technology is to meet the different nutritional standards of pigs according to different growth stages of pigs, and to combine various raw materials to make a full-price compounded material. The nutrition is comprehensive without waste, and the feed reward is high. Different herd nutritional levels (see table).

In addition, a sufficient amount of vitamins and trace elements such as iron, copper, zinc, manganese, and selenium should be added to the feed.
The purchase of feeds and feed additives by farms should be purchased by large-scale feed enterprises with qualifications, good reputation, and high technology levels to ensure quality.

Adhere to scientific management to adjust the temperature of the pig house so that it will be warm in winter and cool in summer, doors and windows will be closed, and heating facilities will be added. Sow delivery room 18 °C ~ 20 °C (Piglet incubator 25 °C ~ 30 °C), piglet cultivation room 20 °C ~ 24 °C. After the pigs are filled with sows and finishing houses, no additional heating facilities are required. All kinds of pig houses in summer should open doors and windows, install fans, and enhance ventilation.

To keep the house dry in the summer, it is necessary to strengthen ventilation in the house and reduce the humidity in the house. In the winter house, it is forbidden to use water to ring and prevent the ground from getting wet. The relative humidity of each type of pig house: 60%~70% of sow house, 60%~70% of maternity room, 60%~70% of breeding house, and 65%~80% of finishing house.

Maintain a reasonable density of pigs and create an environment suitable for the healthy growth of pigs. Area occupied by each pig: pigs 0.3m2~0.5m2, young pigs 0.5m2~0.7m2, finishing pigs 0.9m2~1.1m2, sows 1.5m2~2m2 .

Adhere to the epidemic prevention system for large-scale pig production. Because of the large number of pigs and high concentration of pigs, health and epidemic prevention work is very important. It is necessary to formulate strict disinfection measures and do a good job in environmental sanitation and disinfection. Prevent the invasion of the source. Pig farms should be strictly sterilized in normal times, and more attention should be paid to the disinfection during the epidemic-prone season. Disinfectant can use quicklime, grass ash, caustic soda, chlorine preparations, acid preparations and so on. We must do a regular epidemic prevention epidemic according to scientific immunization procedures, carry out swine fever, swine erysipelas, and foot-and-mouth disease epidemic prevention every spring and autumn. Sows also need to do a good job of preventing epidemic diseases such as parvovirus, pseudorabies, and E. coli. We must also do a good job of prevention of diseases such as paratyphoid fever in piglets and yellow-white piglets in piglets, and strengthen immunity in epidemic-prone seasons.

Strengthen the scale of operations and management of large-scale pig farms Pig farm operations and management include labor management, production management and financial management. Large-scale pig farms should organize production in a rational manner, improve ergonomics, produce more products, and reduce costs. It is necessary to formulate an annual production plan, arrange division of labor among various departments, and coordinate and coordinate with each other to formulate job quotas and post responsibility systems. To achieve variety standardization, dietary standardization, feeding science. Every production link must be coordinated. It is necessary to periodically publish the production schedules, completion tasks, output values ​​and costs of each group so that everyone will have a good idea and seek the greatest economic benefits with the lowest cost.

Strengthen food safety, control excessive use of veterinary drug residues, strictly control the use of feed, veterinary drugs, and other input products, use environmentally-friendly compound feed throughout the process, and strictly prohibit the use of stimulants, furazolidone, sleep sedatives, and steroids to raise or treat diseases. Withdrawal period. Do a good job of pig body, housing, environmental sanitation, ensure the safety of drinking water, daily remove excrement and sewage dirt, and carry out harmless treatment. Ensure that the scale pig farms produce non-polluting, non-toxic (no heavy metal does not exceed the standard), no residual drugs, no animal diseases and high lean meat, good carcass quality, safety and health of pork.
