Four points of wild boar breeding

One, wild boar rearing

The public measures and mother wild pigs were put into the pens for artificial domestication. The wild boar is timid and initially afraid of people. In order to change this weakness of the wild boar, small wild boars are generally purchased for domestication during artificial rearing, and their body weight is in the range of 10 kg-22 kg, because the wild boar at this time is of small age, easy domestication, and plasticity. Strong.

In the process of domestication, wild boars are omnivorous animals and are generally fed twice as often as domestic pigs. Because of their wild habits, they are good at picking raw food. The tender corn, red sorghum, wax gourd, potato (potato), sweet potato, peanut pod, sweet potato vine, corn ear, squash, eggplant, fresh mulberry leaf, fresh sage leaf, and hedgehog are commonly used by farmers. Leaves, carrots, white radish, Chinese cabbage, apples, pears, and persimmons are all foods that they like to eat. When the family is first started, it should be fed with raw food. One month later, half of the raw food should be eaten, and the other half should be the feed of the domestic pig, such as cornmeal, bran, bean curd residue, and powdered residue. Add appropriate salt and mix it with the feed. It slowly changed the habit of eating raw food. After the wild boar basically adapts to the ring feeding, the boar can be fed with the feed of the domestic pig. However, some roots and leaves should also be properly fed.

Second, housing construction

Wild boar sheds are best placed in high ground areas where they are easily drained for easy lighting and ventilation. The original domestic pig house can also be reared with minor modifications. The new enclosure outside the nest requires cement paving. The shed asks for a nest room and an outside nest room. The Liwo Room is for wild boar sleeping and laying, about 3 meters long, about 2.8 meters wide, and a shed and a shed. A general pig house style is built. The roof is covered with straw or straw and the outer nest room is used for wild boar defecation. Diet, exercise and sun exposure are about 3 meters long and 2.8 meters wide. The wall is plastered with concrete and the building height is 1.7 meters to 1.8 meters. A water tank can be built at the root of the wall for drainage, using a masonry cement structure with a length of 1 meter, a width of 0.5 meters and a depth of 23 centimeters. It should be noted that the drinking pool is not easy to build too deep or too narrow, otherwise, when the summer weather is hot, the swine cubs will catch cold in the pool, which will cause suffocation and stillbirth in pregnant sows. A 1 meter wide passageway should be left between the inner and outer chambers to facilitate the free access of wild boars. The gates are generally left in front of the nest room.

Third, breeding technology

Wild boars are coarse and thin, usually grey or gray-yellow. Adult sows weigh 90-130 kg and respond sensitively to the external environment. Female wild boar nipples generally have 6 pairs to 7 pairs, with an annual output of 2 tires, generally 8 to 14 per fetus. Suitable mating time is from 7 months to 8 months after birth and the body weight is 40 kg to 60 kg. In the case of estrus in female wild boars, the principle of using early-born sows with early and sows with late parity is generally adopted. When wild boar estrus occurs, the external genitalia is markedly red and swollen. When the external genitalia changes from red to dark purple, from swollen to slightly shriveled, or the sow's buttocks are held by hand, the best breeding time is when the sow stands still. When mating, the male and female wild boar breeding time takes about a minute or so, which takes slightly longer than domestic pigs. Based on experience, it is advisable to adopt a compounding method, that is, repeat the mating once every 6 hours to 8 hours. This can significantly increase the sow's womb. When the female wild boar estrus is suitable for mating, the boar can also be used to catch the boar for 1 day to 2 days in the sow circle. At this time, the male wild boar can crawl and mate several times at night. After confirming the successful mating, the wild boar was expelled. After 20 days, whether or not the wild boar is still oestrus is observed. In general, the estrous cycle of the female wild boar is 18 days. If no estrus occurs, the boar has been successfully mated.

Fourth, breeding pig selection

Fields and households engaged in wild boar breeding must have 1 to 2 purebred wild boars. As the saying goes: The sows are good and they have a good nest. The boars are good and they are good. This shows the importance of breeding boars. Choosing a good wild boar for breeding is of crucial importance to the pros and cons of future generations. Generally, purebred wild boars that match the characteristics of wild boars, such as their body length, leg height and mouth tip, are selected as breeding pigs. The offspring produced by the special wild boar crossbred with wild boars and domestic pigs are left to breed. The offspring that have been raised have a phenomenon of returning to the ancestors, that is, the pigs produced are not like boars but like pigs in appearance. Therefore, binary hybrids of wild boars are not suitable for seed use. In case of non-use special wild boars for breeding boars, if conditions are limited, we must also select ternary hybrid special boars with more than 70% wild boar virginity as breeding pigs, and also prevent inbreeding in kinship so that their offspring can resist disease. Strong, grows quickly.
