Farmers should strictly control the key links when introducing livestock and poultry improved varieties

In recent years, with the rapid development of the husbandry industry, farmers have deeply realized that excellent livestock and poultry breeds are the fundamental guarantee for improving production performance and product quality and increasing economic efficiency. Therefore, many farmers have actively introduced fine varieties throughout the country, although some breeders have indeed played an important role in improving the performance of the herd, improving hybrid breeds, and increasing economic efficiency. However, some farmers have introduced There is a certain degree of blindness in the varieties, and it is not a good seed but a bad seed. It not only can not play the role of a good seed and create a good economic benefit, but also introduces the disease, causing serious economic losses to the aquaculture industry. To this end, based on years of introduction of practical experience and lessons, we propose that in the introduction of improved varieties, we must pay attention to the key points for the majority of farmers to learn from. The main problems of introduction are that some farmers do not pay attention to the local natural conditions, so that the introduced varieties do not adapt to the local climate, water and soil, and feeding conditions. As a result, the varieties cannot increase production. Some farmers are blindly affected by market speculation. The promotion of fake advertisements in the media was deceived. As a result, the products were sold out of the market and they had to be eliminated, transferred or closed. The economy suffered losses. Some breeders lacked the knowledge of thoroughbred identification, and they were not returned by good breeds but by hybrids or old people. Species, even breeding animals; some farmers ignore the inspection of the disease, do not pay attention to the local livestock and poultry immunization, epidemic prevalence, quarantine conditions, buy back livestock and poultry breeds with incubation period and recessive infectious diseases, and The occurrence of endemic diseases has brought huge economic losses to the breeding industry. The introduction of improved varieties should strictly focus on identifying aspects of the appearance characteristics, age, production performance, hybridization effects, and economic value of the introduced varieties. The introduction of varieties depends on whether the body shape, coat color, mouth and gender have the appearance characteristics of the varieties. When purchasing expensive livestock such as dairy cows, a pastor with practical experience should be employed to check the reproductive organs and reproductive performance. To view the file genealogy and related licenses. When introducing improved varieties from the regular fine-farming farms, it is necessary to check whether there is a “Production Permit for Breeding of Livestock and Poultry and Poultry” issued by the provincial or provincial animal husbandry authority. This is the original farm or expanded farm or commodity farm; whether there are breeds of livestock and poultry, production records, etc. Archives information; whether there is an “operational license” issued by the industrial and commercial department, and consulting and verification of the animal husbandry and industry and commerce departments at the introduction. When introducing varieties into collection and distribution areas, look for ear tags and ear numbers, and whether there are transaction certificates issued by rural and local livestock departments and livestock photos (property rights certificates) that are carried with you. Pay attention to the adaptability of the introduced varieties. To understand the introduced species in the local climate, soil and water, feeding conditions of growth and development and reproduction. It is necessary to compare with the local environment and feeding conditions, and whether it can adapt to the local climate and feeding conditions after repatriation. Strictly carry out inspection of the disease. First, when introducing from a regular breeding farm, in addition to seeing whether there are ear tags and immunization certificates, it is necessary to see whether there is an Animal Epidemic Prevention Certificate, various epidemic quarantine data and relevant routine immunizations. The second is to put a good inspection on the disease, according to national regulations on bovine tuberculosis, Brucella, Porcine ear disease, porcine parvovirus, pseudorabies, bird flu and other infectious diseases for serological testing, found that positive can not be introduced. The third is to see whether there is immune certification and immune ear tag from the introduction of the distribution center. Fourth, attention should be paid to the observation of the presence or absence of clinical symptoms of the disease. Fifth, after bringing the variety back to the farm, we must keep it for 30 days after isolation and observe the absence of epidemic disease, and then raise it according to the routine. During the period of isolation observation, quarantine and necessary immunizations should be conducted for the major diseases. It depends on the market development prospects. Before the introduction, it is necessary to go to the local animal husbandry department and consult with the experts. The variety is currently forecasted and evaluated in domestic and foreign markets. In short, when introducing improved varieties, it is necessary to grasp the knowledge of some introductions. It is necessary to base itself on local and scientific predictions. Only in this way can we fully exert the role of improved varieties.
