Pig farms must renew breeding pigs every year, and the renewal rate and renewal quality are related to the fate of pig farms. However, many people who introduce breeding pigs have many misunderstandings in their thinking, which often leads to the failure of the introduction of pigs, resulting in economic losses, and some even introduce epidemics.
The first is to ignore the health status: this problem is an important issue to be considered first when introducing breeding pigs, some people who introduce breeding pigs consider price and body size when introducing breeding pigs, but ignore the key element of health, and introduce diseases at the same time as the introduction of breeding pigs. When we introduce breeding pigs, we should first pay attention to whether the epidemic prevention system of the pig farm is perfect, whether the implementation is strict, whether the area where it is located is an area without epidemics, and whether the environmental position is conducive to epidemic prevention. If possible, blood tests can also be performed.
The second type is to overemphasize body shape: as long as it is a pig with particularly plump buttocks, regardless of its production performance, it will be blindly introduced, which is a misunderstanding. Lean pig breeds Pitland, Duroc, Hampshire, Great White and Long White all have full legs and hips, and some of these individuals have bimus muscles. Relevant studies have shown that the lactation capacity of two-muscle pigs is 5%-10% worse than that of single-muscle pigs, which directly affects the weaning weight of piglets. In addition, pigs with particularly large buttocks are prone to difficult births, so when purchasing breeding pigs, they should consider its size under the premise of attaching importance to the production performance of individuals. When introducing breeding pigs, boars should focus on traits such as lean meat rate, carcass quality, tassel robustness, growth rate, feed remuneration, etc.; when selecting gilts, they should focus on characteristics related to motherhood, such as the number of births, lactation, viability and maternal quality.
The third is the excessive emphasis on weight: when breeding pigs are introduced, most farmers like to have heavy pigs, but they do not know that this has laid many hidden dangers for future production.
The fourth is to blindly expand the introduction source: many farmers believe that the large number of seed sources and the advantage of hybridization are far more conducive to the improvement of the production performance of the pig farm, and it is not known that the greater the risk of introducing diseases in this way. Because the bacteria, viruses and environment of each breeding farm are very different, and most of the diseases are now hidden infections, the possibility of outbreak of disease after the pigs of different pig farms are mixed, so when introducing seeds, try to introduce seeds from a breeding farm.
