The introduction of pigs when you do not have the error?

Pig raiser must be updated each pig, pig update rate of about 25% -35%. Update rate and update the breeding quality of the production related to the pig raiser. However, when many farmers during the introduction and there are many errors, often leads to introduction of failure, resulting in economic losses, and some even the introduction of disease. Error one: ignore the health status of the first consideration in the introduction of important issues, some of our farmers only consider the price when in the introduction, body, while ignoring the health of the key elements. We should first note in the introduction of the immunization system is perfect pig farm, whether the strict implementation, whether the non-infected area, whether the location in which the environment is conducive to disease prevention. Myth: the pursuit of a large majority of farmers in the introduction of shape when the body too much emphasis on breeding, pig as long as the big hips, regardless of its performance, litter size, feed conversion, lean meat, and other indicators of how the blind introduction. Double muscle hip pig is a pig shape characteristics, Pietrain, Duroc, Yorkshire, Landrace were double muscle phenomenon. The study shows that domestic and foreign experts, two lactating pig muscle capacity than poor single muscle milk 5% to 10%, directly affect the weaning weight of piglets. In addition, a large pig prone hip dystocia, resulting in economic losses. Therefore, when the introduction of pigs, boars to focus lean meat,[link widoczny dla zalogowanych], carcass quality, limb hoof robust, growth rate, feed and other traits. When selecting replacement gilts should be focused on relevant maternal characteristics, such as litter size, milk power, vitality and quality of maternity and other issues. Myth: the pursuit of the introduction of large weight pigs,[link widoczny dla zalogowanych], the majority of farmers friends like a big weight of pigs, does not know that buried a lot of hidden dangers for the future. The introduction of a large pig weight has the following disadvantages: 1. Weight selected large majority of the remaining pig pig,[link widoczny dla zalogowanych], a choice is relatively small, there may be some problems or the growth performance is not ideal. 2. To reach more than 60 kg should be replaced gilts gilts expected, because at this time of sows need a lot of nutrients to promote the development of reproductive organs, and there are many fattening compound growth-promoting agent, can damage the reproductive system development, reducing the heat rate of gilts and breeding pregnancy rate, resulting in great loss. The pig farm are unlikely to change feed, as this will affect the growth rate of pigs, shape and coat color and so on. 3. Back-up to 60 kg pigs after feeding should be limited to avoid excessive fat,[link widoczny dla zalogowanych], but the pig farm will not do the same. So we introduced larger weight when pigs are a bit too fat, if body condition is normal, I am afraid that poor growth rate. Myth: number of breeding farms from the farmers that the introduction of some kinds of sources and more distant blood pigs benefit the field of performance improvement, not knowing to do so the greater the risk of introducing disease. Because all the breeding farms of bacteria and viruses environment very different, and now the majority of diseases were tested latent infection, if mixed with different groups of pig farms after the outbreak of the disease is very high. So when we introduced the introduction of as much as possible from a pig farm.
