Farmers pay attention to buying breeding pigs, but these 4 kinds of misconceptions must be avoided!

Pig farms need to update breeding pigs every year, and the frequency and quality of updates are related to the long-term benefits of pig farms. However, most of them have many common misunderstandings when introducing seeds, and the result is that the introduction fails, causing economic losses, and some even introduce epidemics.

First, the health status is ignored

Breeding friends, health status is the first important issue to consider when introducing seeds, and it must not be ignored. If only the price and body shape are considered when the breeding is introduced, the disease is also introduced back when the breeding pigs are introduced. Therefore, when introducing seeds, we first pay attention to whether the epidemic prevention system of the pig farm is perfect, whether the implementation is strict, whether the area is an epidemic-free area, and whether the environmental position is conducive to epidemic prevention. If possible, sampling tests for blue ear disease, pseudorabies, swine fever and parvovirus may be performed.

Second, too much emphasis on body shape

It is a misunderstanding to focus only on pigs with plump buttocks and blindly introduce them regardless of production performance. Like skinny pig breeds: Pitland pig, Duroc pig, Hampshire pig, large white pig and long white pig have the characteristics of full legs and hips, some of which have double muscle phenomenon, foreign research data show that the two muscles live in the secretion is 5% to 10% worse than the lactation capacity of single muscle injection, which directly affects the weaning weight of piglets. In addition, it is worth mentioning that pigs with too large buttocks are more likely to have difficult births, so when buying breeding pigs, they should consider its body shape under the premise of paying attention to the production performance of individuals.

When introducing breeding boars, it is necessary to focus on traits such as lean meat rate, carcass quality, limb and hoof robustness, growth rate, feed remuneration, etc., while when purchasing breeding sows, focus on characteristics related to motherhood, such as the number of litters, lactation, viability and maternal quality.

Third, like to buy heavy pigs

Most farmers like heavy pigs, but they don't know how to lay many hidden dangers for the future.

The introduction of heavy pigs has the following disadvantages:

1. Under normal circumstances, most of the pigs with large weight are selected pigs, and the selection space is too small, and there may be some problems or unsatisfactory growth performance.

2. Gilts that reach more than 60kg should replace gilt feed, because at this stage sows need a lot of nutrients to promote the development of reproductive organs, and the fertiliser contains a large number of growth promoters, which will damage the development of the reproductive system, reduce the estrus rate of gilts and breeding fertility rates, causing great losses. However, breeding farms generally do not change feed, because this will affect the growth rate and body shape of pigs.

3. After the reserve pig reaches more than 60kg, it should be fed in a limited amount to avoid overweighting, but the breeding farm will not do this either. Therefore, when we introduce pigs with large weight, we are a little overweight, and if the physical condition is normal, I am afraid that the growth rate is not good.

4. The introduced breeding pigs are of greater weight and do not have sufficient time for immunization and deworming before breeding. WeChat's latest policy price is sent to you for the first time, the pig understands the market, gets the pig price in advance, moderately increases or decreases the stock bar, and the pig has no worries. 【xumuweijia(Chinese: animal husbandry for home pinyin)] or search for WeChat public account (animal husbandry expert network) (free oh)

Fourth, from a number of breeding farms to introduce seeds

It is believed that there are many seed sources and blood sources are far more conducive to the improvement of the production performance of the pig herd in this farm, but I do not know that the risk of introducing diseases in this way is greater. Because the bacteria, viruses and environment of each breeding farm are very different, and most of the diseases are now implicitly infected, once the pigs of different farms are mixed with the possibility of outbreak of disease, so the introduction of breeding as far as possible from the fixed breeding farm.
