In the production of pigs, some boars are encountered sometimes, especially in some local pig breeds in China. Sexual maturation is early, sexual desire is prosperous and prone to masturbation. Boar masturbation refers to spontaneous sexual ejaculation caused by abnormal sexual stimulation, sexual impulses and climbing across walls, feed pellets, or other objects. Even the penis rubs against the foreskin and ejaculates. Boars have a long period of profligacy, which can easily result in damage to the penis, weakened constitution, reduced semen volume, immature spermatozoa or dead sperm, and severely affect the mating, resulting in loss of species value. Most of this evil is due to improper management, boars are caused by improper sexual stimulation. For example, if sows are rushed to the vicinity of the boar for mating, the other boars will be irritated when they smell the scent of the estrus sow and climb up on the wall to pout. If the libido is strong, it will automatically ejaculate; or The sow sneaks into the boar to seduce the boar. Because of the obstruction of the fontanelle, the boar cannot mate with the sow. After the orgasm reaches its climax, the penis can cause ejaculation once it hits the stile or trough. A similar situation can cause the boar to be promiscuous as long as it passes several times. How to prevent boar masturbation, the key is to eliminate the abnormal stimulation of the boar. Therefore, the following points should be made. (1) Do not let the boar see the sow, smell the sow, and hear the sow's voice. For this reason, the boars should be built up in the upwind direction of the sow and must be separated by a certain distance. (2) In the estrus season, the sows should be well-circled so that the estrus's sows won't jump out and confuse the boars. (3) Do not rush the sows to the vicinity of the boar. (4) Boars are best fed in a single circle. For boars with strong sexual desire, it is best not to place objects such as food troughs in the circle, and try to eliminate all conditions that may happen to cross the masturbation. (5) For boars that are bred and bred in a single lap, the scent of the sows on the body must be allowed to disappear after mating. (6) Establish a reasonable feeding and management system, regular feeding every day, regular exercise, rest on time, and reasonable use, so as to regularize life. In the non-breeding season, boars that are sexually active will be regularly quarantined at regular intervals if conditions allow. (7) Reserve small boars are more severe in cross-breeding and masturbation than adult boars, and can reduce masturbation by extending exercise time and increasing physical activity. Since mutual cross-breeding and masturbation occurred before the early morning feeding, when the sky was bright, the boars should be driven out and then fed. 4 Wire Intercom System,Analog Intercom System Doorbell,China 4 Wire Video Door Phone,4 Wire Connection System,4 Wire Intercom Zhuhai Mingke Electronics Technology Co., Ltd , https://www.zhmkdz-electronics.com
