After the introduction of segregating breeding pigs, they cannot be immediately mixed with their own pigs. Under the premise of normal detection results, they are isolated for 1.5 months (minimum 15 days), and the basic vaccine is injected before mixing.
Before 80 kg of spare pigs, free-feeding can be adopted. However, pigs that are too fat or too lean need to see the pig's limosis to limit feeding or feeding; , so as not to cause excessive fat and affect the normal estrus, breeding. According to the body condition, the general feeding amount is 2 kg/day/head, and it reaches a medium lye before the breeding. If conditions permit, it is best to feed about 0.5 kg of green succulent green feed each day. On the one hand this can be supplemented with suitable vitamins and cellulose, on the other hand because of increased moisture can increase appetite.
The disease prevention and management of back-breeding breeding pigs, based on the improvement of deworming, prevention and health care, etc., vaccine injection is the key to achieving good results in the future production, and must not be ignored. Vaccination of spare pigs is not the same for all kinds of feeding sites, but the best method is to follow the procedures provided by the farm and the continuity is stronger. Here is a reference to the immunization program for a particular breeder farm. According to the age of the reserve pigs, the introduction of breeding pigs with a weight of 50 kilograms was used as an example. A week later, on the premise of good health, the vaccine was injected every other week. After one month, the vaccine was administered one after another. Injection of swine fever, No. 5 seedlings, pseudorabies vaccine, streptococcus, infectious gastroenteritis and epidemic diarrhea triple vaccine, pulmonary epidemic, Japanese encephalitis, parvovirus.
The reserve breeding pigs before daily sports are required to exercise. Everyday proper exercise can reduce the occurrence of limb diseases, increase appetite, and promote estrus. According to the working hours of the workers and the conditions of the venues, the breeding pigs are usually arranged in the afternoon and put together in the column. The pigs in each bar exercise for half an hour and they do not have to do it every day. At least 2-3 times a week. If there is no playground, it can be carried out within the aisle of the pig house. Pigs should be cleaned up on the sports grounds. All bricks, stones, ironware, plastic products and toxic and harmful substances that are unfavorable to the pigs should be cleaned to prevent pigs. Only cause harm.
Timely Breeding Reserve Pigs Prior to breeding, the husbandry and management personnel must pay close attention to observing the time of their first estrus, and make detailed records to ensure that the actual estrus is referenced. The first estrus situation should also be recorded.
The weight and age of the initial breeding In general, the initial weight of the reserve breeding pig should be 110-120 kg, and the age is more than 8 months old, but it is better not to exceed 10 months old. The initial estrus time of reserve breeding pigs is generally 6 months old, but at this time the body may have matured to meet the requirements, but sexual maturation is not fully achieved. Breeding too early will have adverse effects on the subsequent reproductive performance and body condition recovery. It will result in premature elimination; over 10 months of mating, physiologically normal sows have missed 2-3 affective periods, the effect of mating and the number of litters are unsatisfactory, virtually increasing the cost of feeding and management, thereby affecting the production Achievements.
There are two types of mating methods: natural mating and artificial insemination. For the first time, it is best to use the natural mating method. The gilts that are stable in estrus and the boars that are sexually active should be bred to the breeding stalls. In order to reduce the incidence of sow reproductive tract diseases, sows' vulva and boar's genitals should be cleaned and wiped with clean water before mating, so as to avoid bringing a large amount of pig feces or bacteria and other foreign substances into the sow's vagina. However, most pig farms currently use artificial insemination technology for breeding. If it is a new farm that has just started, when the technology is used, the first time the artificial insemination will be better, the technology will be mature, and then it will be fully developed. The purpose of spending, increasing productivity, and increasing economic efficiency.
