Every pig keeper wants to increase the number of sows and improve the survival rate of piglets, so they will invest a lot of energy in raising sows. But in fact, if the breeding effect of the pig farm is good, raising breeding boars is more important than sows. Because a good sow can guarantee a litter of high-quality piglets, raising a breeding boar means laying a good foundation for N-litters (because a breeding boar has to breed more than 30 sows a year, and if artificially inseminated, it may provide semen to hundreds of sows). So what do you need to pay attention to if you want to raise a good breeding boar?
First, feed
Breeding boars consume a lot of protein to sows, so the diet of breeding boars must ensure the supply of protein. Theoretically, the protein content in the diet of breeding boars should be no less than 15%. In the movie "Walk and See", in order to ensure protein intake, in the era when humans were still hungry, Liu Hei, the animal responsible for breeding, was supplied with two eggs every day. The same goes for breeding boars.
Especially during the breeding season of breeding boars, it is necessary to supplement animal feed. Of course, people today have more options. Eggs don't have to be so extravagant. Fishmeal and blood meal can also be added to the feed of breeding boars. This can supplement the physical damage of the breeding boar and ensure the semen quality of the breeding boar.
Secondly, it should be noted that breeding boars should not be treated like fat pigs. Feeds with high carbohydrate content are not suitable for breeding boars. These feeds can make boars fattened and are not conducive to maintaining body shape. The correct scheme should be based on concentrated feed, supplemented by green feed (the proportion should not be too high). Needless to say, the purpose of green feed is to ensure the normal digestion and vitamin intake of breeding boars. If the vitamin intake is insufficient, it may affect the breeding boar's desire to reproduce, especially in the case of digestive failure.
Second, exercise
Feed less feed with high carbohydrate content, the purpose is to prevent feeding the belly of the big boar, affecting the body size. In order to maintain the size of the breeding boar, it is best to ensure that the breeding boar can move properly. Because regular exercise also helps to improve boar sperm quality and sperm activity. At the same time, it can also improve the appetite of breeding boars, so that their bodies absorb more nutrients, enhance physical fitness and disease resistance.
In addition, we recommend that breeding boars be raised in single tanks to avoid breeding boars biting each other. If you want to polyculture, you should pay attention to reasonable grouping to avoid genital damage caused by fights between breeding boars and affect reproductive function. Of course, the most important thing to avoid is the polyculture of boars and sows, which will seriously affect each other's estrus.
The above are some suggestions on how to raise breeding boars for your reference.
