The selection of breeding farms – a step that determines the future fate of the farm For the first time in the breeding farm, the introduction of reserve breeding pigs is a very crucial step, and it can even be said to be a step in determining the future fate of the farm. Generally, regular breeding farms have business licenses for breeding pigs, but many private pig farms also sell breeding pigs, but they do not have business licenses. This type of breeding pigs generally does not have quality assurance, breeding pigs are uneven, and some use pigs as parents. Breeding pigs or using parental breeder pigs as ancestral breeders are prone to problems after introduction. Therefore, the introduction of breeding pigs should go to regular pig farms with good reputation and quality assurance. It is best to introduce them on the same breeding farm so as to avoid cross-infection of pigs with different antibody levels in different farms. This kind of breeding pigs are generally neat and consistent. The epidemic prevention work is done well. As long as the breeding and management methods are correct, the utilization rate of the breeding pigs is high and the economic benefits are good. The quantity introduced—determining the appropriate proportion according to the situation in hand. The number of imported gilts should be determined according to the situation of the farm itself, such as the number of farrowing houses and the proportion of pigs to be changed, and it is best to gradually sort out their habits based on batches. Introduced. Some pig farmers are relatively impatient. When the new pig farm is launched, all the gilts are led back and they can do it. There are several drawbacks to this: First, the production turnover of their own farms is prone to problems, such as funds, delivery houses, and nursery stalls. Since there are not enough columns, a vicious circle may be formed from the very beginning; second, the mating work is difficult due to The proportion of males and females introduced has been determined. When there are too many gilts at the same time, there is not enough boar or semen to breed. In order not to miss the sow's estrus period, breeding is frequent, resulting in low breeding performance of sows; The habits of imported pigs have not yet been fully grasped and understood, coupled with the lack of their own technical level, they are prone to boredom in the problems that arise in production, thus irritating the introduction of pig farms and completely rejecting the breeding pigs. In fact, this method It is unfair to the breeding farms. Introduce the weight of the breeding pigs - according to the specific circumstances, pay attention to the details In general, for the farms where the pig farms are set up for the first time, the larger the day of introduction of the reserve breeding pigs, the easier it is to manage, especially the spare breeding pigs that can be bred immediately. Many intermediate links, but this may have the following unfavorable factors: In the normal conditions of pig-raising environment (excluding the situation in the pig trough), the majority of breeding pigs generally weigh 50-60 kg/head, if The selection is made at 80-90 kg/head. Except for pre-ordering or breeding pigs that can be bred immediately after the pigs are bought and sold by the customers on the farm, many pigs of this type are pigs left by others, and the quality is worse. The introduction of pigs with a small body weight (not less than 50 kg), although the cost is increased, can be mastered in the prevention of epidemic diseases, laying a solid foundation for future production. For pigs weighing less than 50 kilograms, it is not easy to choose because the body shape has not been stereotyped yet, and the reproductive organs are not obvious. It is better not to choose. Of course, the selection of breeding pigs, but also farms (households) based on their own specific circumstances can not be generalized. The selection of pigs to be introduced - to meet the characteristics of their varieties Breeding of pigs must first meet the characteristics of the respective species, such as coat color, ear shape and other basic characteristics, otherwise it is easy to cause confusion between varieties; Second, it must be completely healthy. Healthy boars are in good spirits, smooth fur, and most of them are agitated, and their tails shake. Pigs with obvious signs of tearing, listlessness, and abnormal walking can't be required. Third, the genital organs should be obvious, the vulva should be large, the size of the nipples should be moderate, and the symmetry should be symmetrical. The effective nipples should be 6-7 pairs. Finally, the size of the reserve pigs is also more crucial. There are many customers who purchase pigs for the first time. When selecting gilts, they are particularly large and full-bodied, while others are secondary conditions. They think that the offspring produced by such pigs will be of good shape and will receive customers. Welcome. In actual fact, although the effects of boars and sows on their offspring account for 50% each, as a female parent, the key role is good breeding performance, and the offspring's size is mainly improved by boars. Therefore, it is generally necessary to select reserve pigs. Choose a healthy pig whose abdomen is normal and whose reproductive organs are normal. To be introduced to the pig's health status - to reach the health level of pigs In order to maintain the health level of their own original herds, health tests should be carried out for the first time or afterwards. It is advisable to collect blood from the breeding pigs that have already been selected in the breeding area. According to the situation you need to know, please have the qualified testing department perform the tests and make a decision based on the results. If the time is urgent, you can also introduce them before the mixed group. Blood test, but there is a certain risk, such as if there are pigs do not meet their requirements, it will be more troublesome to deal with.
