Avoid blindness. Because of the long-lasting and widespread impact of natural conditions on species characteristics, any breed of livestock and poultry has established a highly adaptive relationship with the natural conditions of its place of origin. When they leave the country of origin as a thoroughbred, they may emerge as off-site. Unsuitable for the new environment. Therefore, before introduction, the necessity and possibility of introduction must be carefully studied to avoid blindness. Increased targeting. It is necessary to comprehensively consider the local economic and social development and people’s living standards, introduce targeted livestock and poultry breeds, and in accordance with the regional planning requirements of species, understand in detail the main characteristics of the introduced varieties and whether they adapt to the local natural conditions. Consider the introduction of varieties of production performance, economic value and breeding value. Choose the correct variety. Adaptability of livestock and poultry is a compound trait. Although it is not an economic trait in itself, it can directly affect productivity. Varieties that have a long history of cultivation and a wide distribution area generally have strong and extensive adaptability. The latitude, altitude, climate, and feeding and management of local and country of origin are not far apart, introduction is usually easy to succeed; if the environmental conditions are quite different, special attention should be paid to domestication measures after introduction. Some varieties have long been affected by certain ecological conditions (such as climate, dryness and humidity, vegetation, etc.) to form certain special adaptability, and special attention should be paid when introducing them. In general, it is easier to introduce cold regions from hot regions than from cold regions. In addition, some species lack resistance to certain parasitic diseases or infectious diseases. Once introduced into new areas, they are susceptible to infection and cause massive deaths. Therefore, when introducing, we must not only consider the differences in the environmental conditions of origin and place of introduction, but also consider whether or not we can provide appropriate cultivation conditions for the introduced varieties. Be careful about introducing individuals. In the selection of individuals when introducing livestock and poultry, besides paying attention to the characteristics of the varieties, it is better to pick healthy, normal and underage young livestock and poultry, because such individuals have strong plasticity and are easy to adapt to the new environment. Special attention must be paid to the pedigree review, to the parental and compatriots' productivity, and to prevent the introduction of harmful genes and inherited diseases. In general, it is not appropriate to introduce kinship among individuals, and it is best to use veterinary livestock and poultry from different strains. If technical conditions permit, it is also possible to introduce frozen semen of fine-bred broilers or embryos of good female animals and breeding eggs of good mother birds. Reasonable transportation. Minimizing unpleasant stimuli and reducing stress response in the process of dispatch and transportation is an important measure to increase the survival rate of introduced livestock and poultry. First of all, we should select the appropriate season for transport. The best introduction time is in the season with little difference in climate between the two places. If warm areas lead to cold areas, it is advisable to transport them in summer, and from cold areas to warm areas, it is better to transport them in winter. So that livestock and poultry can gradually adapt to changes in the climate. Secondly, we must effectively strengthen the quarantine system for livestock and poultry, and strictly quarantine them before and after transport. After the species of livestock and poultry have arrived at their destinations, isolation observations shall be carried out to prevent the introduction of infectious diseases and parasitic diseases at the place of origin into the place of introduction. At the same time, it is necessary to do a good job in the specific tasks before and after the dispatch, including the disinfection of vehicles, the organization of people, the measures to prevent the heat and cool down on the way (cold-proof and warm-keeping), and the feeding system, etc. It is advisable to carry some feed from the origin to provide Feed on the way or at the beginning of the new area.
