Matters needing attention when introducing breeding pigs on farms

In order to improve the overall quality of the herd and maintain a higher level of production, to achieve the purposes of constitution, high yield, and high efficiency, pig farms and pig farmers often have to introduce breeding pigs to better quality breeding farms. How can we introduce excellent breeding pigs and can safely and smoothly put them into production and exert their due effects? In the past ten years, the author has introduced pig breeds at home and abroad several times. To sum up, the author should generally proceed with the introduction of breeding pigs in the following aspects.

1 Preparatory work that should be done before introduction 1.1 Establish the introduction plan There are pig farms and raising households should combine their actual conditions, according to the population update plan, determine the required species and quantity, selective purchase can improve the field Pigs of a certain performance, to meet their own requirements, and only to purchase good individuals with the same health status of their own pigs If they are added to the core group for breeding, they should purchase breeding boars or breeding sows. New pig farms should plan on the scale of production of the pig farm, product market, and the direction of the future development of the pig farm, and determine the number, breed and level of the imported pigs, which are foreign species (such as Yorkshire, Duroc or Landrace). Or local breeds, is the original species, the ancestors or parents. According to the introduction program, select high-quality, reputable breeding farms. 1.2 Specific problems that should be known 1.2.1 Epidemic situation There are investigations on the prevalence of epidemics and the quality of various pigs in different parts of the country. Breeding pigs must be imported from healthy pig farms that have not been seriously affected by epidemics and are known in detail. At the same time, understand the breeding farm and immunization program and its specific measures. 1. 2. 2. To understand the selection criteria for breeding pigs in this breed, there are boars that need to know their growth rate (day weight gain), feed conversion ratio (feed weight ratio), back fat thickness (lean meat ratio) and Other indicators. Sows need to understand their reproductive performance (such as the number of litters, conception rate, initial mating age, etc.). The introduction of breeding farms can best be selected in combination with the comprehensive selection index of breeding pigs, especially when introducing breeding pigs from the country. 1. 3 Preparation for Isolation Shelter There are pig farms should be set up in isolation. It is recommended that there be a distance of 300 meters or more from the production area, and 30 days (at least 7 days) prior to the arrival of the breeding pig should be strictly sterilized for the isolation fences and utensils. Choose a good quality disinfectant, such as Zhongshan "Tengjun" organochlorine disinfectant, to carry out many strict disinfection.

2 Problems to be noticed in seed selection 2.1 Breeding pigs require health, no clinical signs and genetic disorders (such as umbilical hernias, hernias, etc.), good nutrition, normal development, reasonable combination of limbs, strong and strong, and good appearance Variety characteristics and the requirements of the field itself, clear ear number, purebred pigs should be earmarked for identification. The boars are required to be lively and active, the testicles are well-balanced, and there are no more effusions in the foreskin. The adult boars are best advised to see boars that can actively cross, have a large amount of foam in their mouths, and are sexually robust boars. The reproductive organs of the sow are required to develop normally. The vulva should not be too small and upturned. Individuals with large vulva and sagging should be selected. Effective nipples should be no less than six pairs. The distribution is evenly called and the limbs are required to be powerful and well-structured. 2.2 Breeding farms should try to meet the requirements of users, set up special sales observation rooms for customers to select, ensure the quality of breeding pigs and safeguard the interests of customers. 2.3 Requirements for the farm to provide the immunization program and the status of the swine immunization purchased, and indicate the dates of various vaccine injections. It is advisable to sell the boars after measurement, together with the data and the third generation pedigree of the breeding pigs. 2.4 Sales of breeding pigs must be conducted by the veterinarian clinical examination without swine fever, wilt, brucellosis and other diseases, and the veterinary quarantine department issued a quarantine permit before they can be allowed to sell.

Matters needing attention when transporting 3 kinds of pigs 3.1 It is better not to use the foreign vehicles of the transporting goods pigs to transport the breeding pigs. Starting from the 24 hours before the breeding of pigs, vehicles and utensils should be strictly disinfected more than twice with efficient disinfectants. It is advisable to load the pigs after vacant one day and use less irritating disinfectants before loading pigs. "Teng Jun" double chain quaternary ammonium salt complex iodine) is thoroughly disinfected once and a disinfection certificate is issued. 2. 2 In the process of transportation, measures should be taken to reduce the stress of pig breeding and limb hooves, and to avoid death and infection in transit. The feedlots are required to stop feeding the feedstuffs for the transportation of the breeding pigs 2 hours in advance.The pigs should not be rushed to the vehicle when they get on the train, and the pigs should be protected.The 3rd long distance transportation should be fixed after the pigs are finished. The vehicle is best equipped with dunnage, with straw, rice husks, sawdust in the winter and fine sand in the summer to reduce the possibility of damaging pigs' feet and feet; the number of pigs loaded should not be excessive. Too dense will cause squeezing which will result in the death of the breeding pigs; the carriages carrying the breeding pigs will be divided into several partitions, and 4-6 pigs will be arranged as a fence. The fences are best made of smooth water pipes to avoid scratching the breeding pigs. Sexually mature boar Separate them separately and spray a disinfectant (such as a complex phenol) with a strong odor to prevent boars from fighting each other. 3.4 For long-distance transport of pigs, long-acting antibiotics should be injected at 1 ml/10 kg per pig (eg " Demi Xian "or Teng Jun" love animals, to prevent pigs infected with bacterial diseases on the way to the soft clinical sound of the pigs, can be injected chlorpromazine and other sedation. 4. 5 long-distance transport of pigs Should drive the highway as far as possible to avoid traffic jams, each vehicle should be equipped with two drivers to drive alternately. The driving process should avoid sudden braking; the way should be chosen to eat without parking other animal-carrying vehicles, and must not be transported with other pigs. The vehicles are parked together; the necessary tools and medicines such as ropes, iron wire, pliers, antibiotics, antipyretic fever, and sedatives should be prepared for the vehicle. 3.6 Care should be taken in winter and heatstroke in summer should be avoided. During the summer season, the pigs are shipped. In the summer, the pigs should be kept at hot noon, and they can be shipped in the morning and early evening. During the season, they should pay attention to the regular supply of drinking water. Preparation of watermelon for breeding pigs to prevent breeding pigs from heat stroke, and to find a reliable source of water for the breeding pigs to cool water, generally 3-6 times a day.. 3.7 Pig transport vehicles should be equipped with car canvas, if it encounters a hot sun or a storm, The canvas should be covered on the top of the roof to prevent direct sunlight and storms from hitting the breeding pigs, and the tarpaulins on both sides of the carriage should be hung for ventilation and cooling; winter canvas should be hung over the front of the carriage to keep the wind warm. Prepare some electrolyte solution, use powdered milk, use the powder on the road to feed the pigs, stop at the right time during the transportation, check the pigs without disease, and prepare a spare car for a large amount of transportation so as to avoid the failure of the pig transporter. Too long to cause unnecessary losses 3.9 Pigs should be constantly observed, and if there are abnormalities such as shortness of breath and elevated body temperature, take effective measures, injectable antibiotics and antipyretic injections, and use Lower water flushing pigs cool down, and ear tip bleeding therapy may be used if necessary.

Things to Do After 4 Kinds of Pigs Have Been Present 4.1 Newly introduced breeding pigs should first be kept in isolation quarters instead of directly into the pig farm production area, because doing so is very likely to bring new diseases or the same strains caused by different strains. disease. 5. After the two pigs arrive at the destination, they immediately sterilize the ground around the unloading platform, vehicles, pigs and unloading vehicles. Then the sires are unloaded and bred in groups according to size and male and female. The breeding pigs with injuries and prolapse should be immediately separated. Billing column feeding, and timely treatment and treatment. 4.3 First provide the pigs with drinking water. After 6-12 hours of rest, feed a small amount of feed. From the second day onwards, gradually increase the amount of feed. After 5 days, resume normal feed. In the first two weeks after the arrival of the breeding pig, due to fatigue and environmental changes, the body's resistance to the disease will be reduced, feeding and management should pay attention to minimize stress, can be added to the feed antibiotics (tiamulin available 50mg/kg , chlortetracycline 150mg/kg) and a variety of vitamins to restore the pigs to their normal state as soon as possible. 4.4 Isolation and Observation: After the breeding pigs are on the farm, they must be kept in the isolation house for 30-45 days for strict quarantine. In particular, attention should be paid to such diseases as Brucella and pseudorabies (PR), and blood must be collected and tested by the relevant veterinary quarantine department to confirm that there are no bacterial infections and viral wild virus infections, and to monitor antibodies such as swine fever and foot-and-mouth disease. 4.5 All kinds of vaccine such as swine fever shall be vaccinated in accordance with the immunization procedure for the first time since the arrival of the breeding pigs. The 7-month-old replacement pigs may be given some immunizations for reproductive disorders, such as parvovirus, type B. Encephalitis vaccine, etc. 4.6 Breeding pigs In the isolation period, after vaccination with various vaccines, a total deworming can be carried out using either doramycin (such as Pfizer "killing") or long-acting ivermectin (such as Tengjun "Kenway". The broad-spectrum insect repellent such as ")" was injected subcutaneously to repel insects so that they could fully develop their growth potential. After the isolation period is over, the body of the batch of pigs is disinfected, and then transferred to the production area for normal production.
