A few days ago heard a news, in 2018, Hebei Ruibang pig farm PSY can reach 30; it is understood that the environmental conditions of this pig farm is first-class, the management is also in place, the pig farm has not been any serious diseases appear; but to talk about merit, excellent breeds are ranked first, because if not produce so many piglets, it is impossible to achieve this result.
A few decades ago, China's pig breeding is basically a local breed, people's understanding of the importance of breeds is not high; at the same time, because of the limitations of breeding conditions, they are all suitable for local breeds, such as Taihu Lake pigs in the Taihu Lake Basin, Northeast people's pigs in the northeast region, Dingxian pigs and Deep County pigs in Hebei, Tibetan pigs, etc.; but now in addition to the pig farms and remote areas that are protected, it is rare to see local varieties; this is a new breed that people have unconsciously accepted.
The above is enough to show the importance of breeds, but often passively accepted, rather than actively selected; this also leads to many pig breeders in the selection of breeds, just choose varieties with excellent production performance, and ignore the excellent production performance behind, but there are many weaknesses hidden, and finally in the feeding process, there are constantly various problems, and some even raise pigs at a loss. Choosing a good variety is a natural thing, but also to know what a good variety is, here are a few factors that a good variety should have. The first is excellent reproductive performance, such as obvious estrus, high number of litters, more milk, etc.; secondly, excellent production performance, such as growth rate, feed utilization rate, lean meat rate, etc.; third, we must consider the adaptation performance, which must be adapted to the conditions of our own pig farm.
The above three conditions, people often pay attention to the first two and ignore the third, which is the main reason why pigs are not easy to raise in recent years. As an ordinary pig farmer, you will not know all the situation of the introduced pigs; in addition to the introduction of the breeding farm, you must also understand the situation of the breed through other channels; more importantly, you must learn to judge, because whether it is suitable for the pig farm, in addition to understanding the situation of the introduced pigs, you must also be clear about the situation of your own pig farm.
