--------------------------------------
I. Scientific Feeding
1. Supply sufficient animal protein feed: Breeding boars require relatively large amounts of crude protein. If the protein in the daily ration is insufficient, it will result in boars producing less and thinner semen, incompletely developed sperm, poor vitality, a decreased conception rate, and even loss of breeding ability. Therefore, sufficient animal feed must be supplied, such as fish meal, bone meal, soybean meal, small shrimp, silkworm pupae, etc., to improve the quantity and quality of breeding boar semen. The Zhaobao Ecological Farm in Yongding County, Fujian, used culled rare poultry and game to feed breeding boars and pregnant sows, with excellent results: each sow farrowed more than 12 piglets per litter, and every wild boar piglet was glossy and very robust.
2. Supplement sufficient vitamins: Breeding boars have a high demand for vitamins, especially VE, VB1, and VB2. If insufficient, it will affect the breeding boar's constitution and semen quality. Because wild boars consume large amounts of green, succulent feed rich in vitamins, they generally do not lack vitamins. In northern winters, when green and succulent feed is insufficient, or after boars mate, vitamin additives should be appropriately supplemented.
3. Add an appropriate amount of minerals: A lack of minerals will affect the health and semen quality of breeding boars, especially calcium, manganese, zinc, and selenium. Normally, more calcium-rich green and succulent feed and dried grass meal should be fed, along with bran rich in phosphorus, and an appropriate amount of bone meal, stone meal, or shell meal should be supplemented.
4. Strengthen nutrition during the mating period: For boars bred seasonally, the nutritional level should be gradually increased starting 45 days before mating; for wild boars bred year-round, the nutrients required by breeding wild boars should be supplied in a balanced manner. The amount of green and roughage fed to breeding boars should not be too large, to avoid developing a grass belly and affecting mating. The amount of the daily ration should be 2.5% to 3% of body weight.

II. Scientific Management
1. Appropriate exercise: Exercise is an essential measure for strengthening a boar's constitution, ensuring its vigorous libido, and improving sperm vitality. When wild boars are young, they should be given appropriate exercise, allowing them to exercise for 1 to 2 hours every day.
2. Good sanitation: The pig house must be washed every day, kept clean, ventilated, and dry, warm in winter and cool in summer. In winter, spread bedding straw to keep warm; in summer, prevent heatstroke and lower the temperature. At the same time, the pig's body must also be kept clean. Brush the pig's coat once a day with a hard-bristled brush, which is extremely effective for ensuring the health of wild boars and preventing various diseases.
3. Regular weighing: Weigh breeding boars regularly to understand changes in body weight, so that the nutrition in the daily ration can be adjusted at any time. In short, boars must remain neither fat nor thin, with a straight back, a belly that does not sag, agile movement, and vigorous libido.
