The ability to breed boars, the quality of semen quality, and the length of years of use are not only related to feeding and management, but also depending on the initial age and intensity of use. First, how old boar should be equipped with age 1 boar sexual development is divided into two stages of puberty and sexual maturity. Before sexual maturity, there is a certain sexual performance, even mating actions, but it is also different from the real typical sexual behavior. Often there is no ejaculation or no sperm in the semen. Some customers see boars crawling pigs and make them breed. This is definitely not desirable. 2 When the boar is 5 to 6 months old at sexual maturity, although it has normal reproductive ability, the body is still in a rapid development stage. If the breeding is started at this time, the energy consumption is very large, and the use limit of the boar must be shortened. The rate is also low. The appropriate initial mating age, foreign breeding boar breeders, Du, Chang, and Boars should be mated at an appropriate period of 8 months and a body weight of 120 kg or more. However, it is not appropriate for the boar to be used too late, which is not only economically uneconomical, but also makes the boar disturbed, affects sexual desire, is not conducive to normal development, and even causes masturbation and other evils. Second, how to train and match the boars for the first time. Because the boars grow up in isolation, they often do not have the opportunity to learn how to crawl and mate with sows. If you encounter a sow with poor estrus or place it with many sows, you may lose the courage to mate again if there are several unsuccessful attempts. Therefore, for the first breeding of young boars, an experienced breeder is required to ensure successful mating. The first mating should select the small sows, and the heat is very good, do not rush to hold the penis after the boar cross, wait for the penis several test unfinished, and then assist in mating by hand to prevent boars are not used to retreat Down. For boars with sexual desires that do not climb, gently massage the penis by hand, and assist them in climbing for mating when emotions are high. Third, why some boars will prematurely boar breeders must have a healthy constitution, good semen and strong sexual function in order to ensure boar breeding capabilities, extend the useful life. However, due to improper feeding and management, or poor breeding techniques, etc., boars are often subject to early decline. The reasons are as follows: 1 Breeding prematurely can cause boar premature aging. For this reason, it is necessary to overcome the early mating and perform mating. 2 Single feed, too little green fodder, malnutrition of male boars or excessive breeding, resulting in premature boar decline. For this purpose, quality and reliable premixes, as well as proteins with a full amino acid content, should be used to formulate full-priced feeds. And strictly control the number of breeding. 3 Insufficient long-term captive movement, or high energy feed, makes the boar fat, libido weakened, semen quality decline, loss of breeding ability. To do this, you must feed high-quality full-priced feeds. Ensure that boars do 4 to 8 kilometers of full-time exercise each day to reduce phlegm and maintain a strong breeding ability. 4 Boar sows have drawbacks in the same cycle. Due to frequent contact, it not only affects appetite and growth, but also can easily reduce sexual desire and breeding ability and reduce the service life. For this type of boar must be raised in a single circle, keep the environment quiet, free from external stimuli, do not surprise the boar. It is best to keep the boar away from the sow and not hear the sow and smell the sow. Fourth, how to reasonably use the boar is very important for the rational use of the boar. It is harmful if the mating is too frequent or long-term use. Appropriate use of strength is 1 to 2 years old young boar, breeding 2 to 3 times a week. For male boars over 2 years of age, they can breed 1 or 2 times a day (once every morning and evening) in the case of a high level of feeding and management, and take a day off for 4 to 6 days. Older boars should be eliminated in time. V. How to properly breed pigs 1 It is advisable to mate with pigs one hour prior to early feeding and late feeding. It is best to stay away from the barn to avoid disturbing other boars. Mate assistance should be given when necessary. When the boar climbs on the sow, the tail of the sow must be pulled out in time to prevent the boar's penis from rubbing on the outside for a long period of time. Injury or in vitro excretion may occur. Keep quiet during mating. Do not shout and whip the boar. 2 When matching the size of the male and female pigs during mating, choose slope adjustment. After mating, gently press the waist with your hand, do not let it bow or immediately lie down, to prevent backflow of semen. Do not bathe and feed immediately after mixing. 3 Boars are livestock that have been repeatedly deprived of sperm. The mating time is as long as 15 to 20 minutes, and the ejaculation time is 5 to 6 minutes, which leads to greater physical exertion. Generally do not have to control, let it go back. However, when the mating amount is large and concentrated, in order to reduce physical exertion, it is advisable to control the number of ejaculations per mating at two times, so that the sow can be moved forward and the boar can naturally slide down. Boar ejaculation can be judged based on whether the anus is fluctuating.
