Kind of selection of male wild boar. When selecting male wild boars, the appearance requires that the coat color is grayish black or brownish red, coarse hair is thin and thin, the tip of the ear is small, the tip of the mouth is long, the head and abdomen are small, the feet are tall, the back straight is not concave, and the teeth are sharp. At the same time, it is required that the sexual characteristics be obvious, the forefront is wide and wide, the sexual function is vigorous, and the testis is well-balanced. It is resistant to rough feeding at 18 months and above, fast feeding, large food intake, and no picky eaters. This kind of male wild boar has strong breeding performance. In addition, semen can also be collected from the genitals of a female wild boar that has just been reared for sperm quality testing, and sperm viability must be above 0.6. In general, purebred wild boars that meet the characteristics of wild boars should be selected as breeding pigs. If the offspring produced by wild boars and domestic pigs are used for the breeding of offspring produced by special wild boars, the offspring produced will have the phenomenon of returning to the ancestors, that is, the pigs produced will have appearances. Some are not like wild boars but like domestic pigs. Therefore, binary hybrids of wild boars are not suitable for use as a seed. If conditions are restricted and non-specialty wild boars are used as breeding boars, they must also select three-way hybrid special wild boars with more than 70% of wild boar's blood as breeding pigs. In addition, they must also prevent inbreeding in the blood relationship. In this way, their offspring should be resistant to disease. Strong, grows quickly.
Prevent male wild boar fat. The male wild boar was originally a wild animal, and it was mainly eaten with leaves and weeds. This property was preserved under artificial rearing. 60%-70% of the feed was mainly green grass such as green grass and green vegetables. Some farmers have used the experience of raising pigs to feed male wild boars with full-priced feeds, which not only greatly increased the cost, but also resulted in the lack of restrictions on the early growth of reserve pigs and the excessively high nutritional level in the diet. Wild boars are over-fertilized and over-weighted. This results in difficulty in climbing wild boars or in the ability of sows to survive through boars, resulting in difficulty in breeding or inability to breed. Therefore, the wild boars should be properly reared, green feed should be used as the main food, and sports should be strengthened.
Supply balanced nutrition. Male wild boars need more crude protein and vitamins. If the content of the boar is insufficient or unbalanced, it will affect the quality and quality of male boars, resulting in less semen and dilute sperm, incomplete sperm development, poor vigor, reduced fertility rate, and even loss of fertility. Breeding ability. The lack of minerals such as calcium, manganese, zinc, and selenium can also lead to degeneration of the gonads and sluggish libido. Therefore, the nutrients needed for breeding boars should be balanced. Fishmeal, soybean meal, shrimp, silkworm cocoon and other feeds rich in high quality protein should be adequately supplied all year round. During the mating period, 1 to 2 eggs or 1 cup of milk can be supplemented, and more vitamin-rich green feeds should be fed. Usually, bone meal and minerals should be supplemented. Or shell powder and so on.
Strengthen your exercise and enhance your physical fitness. Some farmers have excessively used male wild boars or forced male wild boar movements, resulting in a decline in male boar physique, resulting in dislike or disapproval. For such male wild boars, exercise should be intensified, and they should be allowed to perform 1 to 2 hours of exercise each day. The distance can be 1.5 to 3 kilometers. This is an indispensable measure to enhance boar constitution, ensure their vigorous sex drive, and improve sperm vigor.
