Breeding Management of Special Male Wild Boars

The special wild boar market is hot, and the benefit of raising wild boar is good. at present, in Guangdong Wildlife Wholesale Market, the wholesale price of wild boar gross weight is up to 30mur40 yuan / kg, which is equivalent to the price of 8 domestic pigs. However, in order to achieve high yield, fast growth and high efficiency, we must firmly grasp the management of breeding boars. The quality of boars determines the production of a pig farm.

The special wild boar market is hot, and the benefit of raising wild boar is good. at present, in Guangdong Wildlife Wholesale Market, the wholesale price of wild boar gross weight is up to 30mur40 yuan / kg, which is equivalent to the price of 8 domestic pigs. However, in order to achieve high yield, fast growth and high efficiency, we must firmly grasp the management of breeding boars. The quality of boars determines the production level of a pig farm. As the saying goes, "good female, good litter, good male, good herd." One word points out the key role of breeding boars on the product quality of the offspring of the whole farm. Special wild boar breeding boar must be physically strong, energetic, responsive, broad chest, large skeleton, symmetrical and strong in all parts of the body, obvious male characteristics, strong sexual desire, and can produce a large amount of semen of high quality. The management technology of breeding boar is introduced as follows:

1. Scientific breeding

The main results are as follows: 1. Breeding boars need more crude protein, such as insufficient protein in diet, which will result in less and sparse semen, incomplete sperm development and poor motility, decrease conception rate, and even lose breeding ability. Therefore, animal feed, such as fish meal, bone meal, soybean meal, shrimp, silkworm pupa, etc., should be supplied year round, which has a significant effect on improving the quantity and quality of boar semen. Relying on the advantages of its own rare poultry farm, Zhaobao Ecological Farm in Yongding County, Fujian Province, uses the eliminated rare birds and game to feed breeding boars and pregnant sows with excellent results. Sows give birth to more than 12 babies per birth, and all the young wild boars are smooth and strong.

2. Breeder boars need more vitamins, especially VE, VB1 and VB2. If insufficient, it will affect the physique and semen quality of breeder boars. Wild boar due to a large intake of green succulent feed rich in vitamins, under normal circumstances will not be lack of vitamins, in the northern winter green succulent feed shortage or boar mating, can supplement vitamin additives.

3. Mineral deficiency can also affect the health and semen quality of breeding boars, especially calcium, manganese, zinc and selenium. Usually, you can feed all kinds of green succulent feed and hay powder with more calcium, bran with more phosphorus and proper amount of bone powder, stone powder or shell powder, etc.

4. The seasonal breeding boar should gradually improve the nutrition level 45 days before breeding, and the wild boar with perennial breeding should balance the nutrients needed for breeding wild boar all the year round. The amount of concentrate feed for breeding boars should be more than that of other types of pigs, and the green roughage should be less, so as not to form grass belly to affect breeding, and the volume of the diet should be 2.5% of body weight. 3%.

II. Scientific management

1. Proper exercise is an indispensable measure to strengthen the physique of boars, ensure their exuberant libido and improve sperm motility. When the wild boar is young, it is necessary to give it proper exercise and let it exercise for 2 hours a day, which is 4 miles away.

2, to do a good job of hygiene, we must wash the pig house every day, be clean, ventilated and dry, warm in winter and cool in summer, lay mattress in winter, and prevent heat and cool in summer. At the same time, it is necessary to keep the pig body clean. Zhaobao Ecological Farm in Yongding County, Fujian Province uses a hard hair brush to wipe the fur of wild boars once a day, which proves to be very effective in ensuring the health of wild boars and preventing various diseases.

3. Weigh the boars regularly to understand the changes of their body weight so as to adjust the nutritional structure of the diet at any time. In short, boars must not be fat or thin, straight, belly not drooping, flexible, libido.

Estrus and breeding of wild boar

The coat of wild boar is thick and thin, usually gray or grayish yellow. Adult sows weigh 90 kg ~ 130 kg and are sensitive to external environment. There are generally 6 ~ 7 pairs of wild boar nipples, with an annual production of 2.5 babies, usually 10 ~ 15 per fetus. The suitable mating time is from 5 months to 6 months after birth, and the body weight is 40 kg ~ 60 kg. When sows are in estrus, they generally adopt the principle of early mating of first-parturient sows and late mating of parturient sows. When the wild boar is in estrus, the external genitals are obviously red and swollen, and when the external genitals change from red to dark purple, from swelling to slight wrinkle, or when the hands press the buttocks of the sow, and the sow stands still, it is the best time to breed. The mating time of male and female wild boars is slightly longer than that of domestic pigs. According to experience, it is best to adopt multiple mating, that is, mating again after an interval of 6 to 8 hours. This can significantly improve the conception rate of sows. When the female wild boar is in estrus, the boar can also be driven into the sow pen for 1 ~ 2 days, when the boar can climb and mate many times at night. After confirming the success of mating, drive out the boar. After 20 days, observe whether the wild boar is still in estrus. Generally, the oestrus cycle of the wild boar is 18 days. If not, it proves that the wild boar has mated successfully.
