In recent years, the output value of animal husbandry has accounted for half of the total agricultural income. Professional farmers and free-range agricultural production in various animal husbandry communities have gradually increased. In order to improve varieties, it is necessary to introduce good breeding stocks. Animal husbandry communities, professional farmers and free-range farmers should often go out and introduce fine breeding pigs. However, due to the varying levels and experience of the farmers, some people do not understand what kind of breeding pigs to introduce, and how to proceed with the selection and transportation of breeding pigs. Here are some suggestions for these issues. 1 The purpose of introduction is clear According to the needs of breeding and production, the introduced varieties and crystal systems are mainly determined to promote the renewal of blood. It is not advisable to raise too many varieties in the same farm. It is generally easier to manage 2 to 3 varieties. It is not possible to pursue variety improvement only by pursuing variety and quantity. For example, if a free-range farmer introduces, the breeder's breed should be determined according to the lineage of the surrounding sow. If the sow is mostly white, the York breed can be introduced. If the sow contains Changbai and York descent, it can be introduced. The Locke variety further enhances the hybridization advantage. 2 introduced pigs must be able to adapt to the local feeding environment In addition to genetic factors, the production performance of breeding pigs is also subject to external temperature, humidity, feed, management and other conditions. Only the acquired feeding management and environmental conditions meet the requirements to fully reflect the excellent characteristics of the breeding pigs. 3Select large-scale breeding farms with good quality and high reputation Choosing such breeding farms can guarantee quality, avoid problems such as impure variety and introduction of infected pigs, and will have good after-sales service to ensure that problems will be properly handled and will not bring large economic losses. 4 identification of physical and external appearance After determining the variety to be introduced, you should choose excellent individuals with thick limbs, strong skin, full buttocks, symmetrical testicles, strong body, less meat and less foreskin. In addition, there is a strong libido in the eyes and the white foam. In order to prevent the adjustment of the package, the breeding pigs will be selected for photography for identification. 5 ask for the scorecard After selecting the breeding pigs, it is necessary to know in detail the pedigree records of the breeding pigs. The offspring of the breeding pigs with genetic defects such as cryptorchidism and scrotal hernia should be selected for pedigree recording. And through the pedigree, we can understand the reproductive performance, fattening performance, adaptability, disease resistance, heritability and other functions of the breeding pigs, so that the future feeding management and breeding production can be counted. 6 strict quarantine 6.1 Quarantine before transfer The breeding stocks are quarantined in the original farm or isolation field within 1.5 to 30 days before the start of shipment. Understand the epidemic situation of the pig farm in the past six months, check the file and vaccination records of the pigs, and then carry out group and individual quarantine, and make detailed records, and finally make clinical examinations and laboratory tests. Pigs mainly detect foot-and-mouth disease, swine fever, swine vesicular disease, porcine mycoplasmal pneumonia, and pig Helicobacter pylori. Those who have been examined and determined to be healthy shall be issued an Animal Quarantine Certificate and will be allowed to start shipping. 6.2 Quarantine during transportation When the pigs are shipped, the local animal epidemic prevention supervision agency shall send personnel to the site for supervision and inspection. Vehicles, ships, engine rooms and feeding utensils carrying pigs must be cleaned, washed and disinfected before loading. After passing the inspection by the local animal epidemic prevention supervision agency, the transportation quarantine certificate will be issued. During transportation, forages, drinking water and related materials are not allowed to be filled at stations, ports and airports in infected areas. During transportation, the escort should always observe the health status of the breeding stock, and find out that the abnormality should be timely contacted with the local animal epidemic prevention supervision agency and dealt with according to relevant regulations. 6.3 Quarantine after arriving at the destination After the pigs are on the scene, according to the quarantine needs, observe the isolation field for 15 to 30 days. During the period of isolation observation, quarantine shall be carried out, and it shall be used for breeding, production and use after being confirmed as a healthy breeding pig. Mastering the above 6 points, the process of purchasing pigs can be targeted and promote the development of the pig industry.
