Six sows should be eliminated
Under normal circumstances, if the sow has produced eight litter piglets, the farrowing rate will decline and the sows will be able to retired. However, some sows may also experience abnormalities during the breeding season. The sow should be retired early. The first one that should be eliminated is a sow who has acquired a viral infection. For example, swine fever, pseudorabies, and sows who have acquired this type of infectious disease are cured after the use of drugs, and are likely to be re-infected at the next litter and will be transmitted to piglets. To avoid further economic losses, sows should not Hesitated to eliminate these sows. The second is the occurrence of breast inflammation, uterine inflammation, decreased piglet ability, and decreased milking power and must be eliminated. If you think about it, you have a big litter of pigs but you are not able to feed it. Such a mother must be incompetent. It is best to rush to resign. The third kind of sows that should be eliminated is the ones with defective limbs. For example, if a sow whose socks are lame, not only the breeding will be affected, but also due to the lack of normal activities, the constitution will not be good, even if the piglets are born. It will not be healthy. Another is that in the normal feeding process, piglets born per birth have a slow growth rate and a poor body shape. Such sows are to be eliminated. They are affected by the genetics of the sows and cause slow growth of piglets and finishing pigs. The fifth species that should be eliminated is breeding sows that are difficult to achieve, that is, the use of drugs to promote its estrus, but generally there will be difficulties when the next breeding, it is easy to cause empty, not breeding, resulting in economic losses. Such a sow can't stay seeded. It's best to eliminate it early. In addition, some sows are affected by genetics, and the farrowing rate is very low. Only three or four piglets are born per child. Such sows are not qualified and must be eliminated in time. Denilco Environmental technology(Suzhou)Co., Ltd. , https://www.wflood.com
