When breeding boars, they must pay attention to their nutritional status, keep them healthy and strong throughout the year, and have a strong sexual desire.
Boar fat, libido will weaken or even no sexual desire, resulting in decreased ability to breed. This situation is mostly due to a single feed, too much energy feed, and insufficient feed for protein, minerals, and vitamins. Energy feeds should be reduced in time, protein feeds and green succulent feeds should be added and exercise must be enhanced. Boars are thin, with reduced precision, and poor semen quality, resulting in low conception rates for sows. This situation is mostly caused by malnutrition or excessive breeding. It is necessary to adjust the feed, strengthen nutrition, reduce the number of mating, and restore the use of constitution.
The boar diet should be mainly concentrated material, limited feeding, appropriate amount of green feed, less feed high energy feed, to prevent breeding pigs fat. But you can't feed too much roughage, so as not to stretch the belly and prevent mating. There should be more than three kinds of dietary composition, and the protein content should not be less than 16%. Animal feeds such as silkworm cocoons and fishmeal should be properly fed. Beans, cakes and big wheat are good feeds for feeding boars. High-energy feeds such as corn and rice bran should not be fed in large quantities. In the season of breeding, small fish or eggs should also be properly fed to improve semen quality.
Appropriate exercise can increase the metabolism of boars, promote appetite, enhance physical fitness and improve semen quality. Always comb the skin to keep the skin clean and have a preventive effect on the skin.
