5.Production Process Large-scale pig farms should implement segmented feeding based on the physiological characteristics of breeding boars, replacement boars and sows, breeding sows, nursery pigs, and growing-finishing pigs. The pig herd is raised to form a production process that operates continuously, evenly, and cyclically throughout the year, and production is organized in accordance with the pig herd turnover process of GB/T 17824.1.

7.1 Introduction and Seed Saving

7.1.1 A plan for introducing or retaining breeding stock should be formulated based on the production needs of the pig farm. The plan should include. breed or strain, source of the breeding stock, introduction time, and quarantine method. Laws and facilities, diseases and performance testing.

7.1.2 Breeding pigs or semen should be imported from units with qualifications for breeding livestock and poultry production and management. Purebred pigs should have pedigree records for no less than three generations. Relevant performance testing data. After introduction, breeding pigs should be quarantined and observed for at least 30 days, and only after passing quarantine confirmation can they be introduced into the herd. If imported from abroad... The planting should be carried out in accordance with relevant national regulations.

3.5 kg, and for fatty-type boars, it should be

2.5 kg. The recommended daily feed intake for pigs is

7.2.1.2 The frequency of mating or semen collection for boars should be once or twice a week. Replacement boars can be used one to two months after sexual maturity.

7.2.2.2 Before sexual maturity, allow free access to feed, adjusting the nutrient level of the feed appropriately according to the body condition; after sexual maturity, feed should be provided in accordance with the provisions of GB/T 39235. Implement restricted feeding.

7.2.3 Breeding sows

7.2.3.1 Non-pregnant sows should be kept in a suitable body condition to promote estrus and ovulation.

b) Prepare delivery tools such as heat lamps, delivery cloths, drying powder, and placenta containers, and sterilize them for later use;

c) The vulva and udder of the sow should be cleaned and disinfected before farrowing.

7.2.3.5 Lactating sows should be housed in farrowing pens, with ample access to water and feed. Postpartum care should be provided as follows:

b) If purulent discharge is present from the vagina of a sow after farrowing, prompt treatment is necessary;

c) Closely observe the sow's feeding behavior after farrowing. If the sow is found to be not eating or eating less, check her body temperature and take timely treatment measures.
