First, avoid blindness Since natural conditions have a long-lasting and extensive impact 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 will inevitably lead to different places. Breaking its coordination with the environment, it shows its inability to adapt to the new environment. Therefore, before introduction, the necessity and possibility of introduction must be carefully studied to avoid blindness. Second, enhance targeted 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 for species, understand in detail the main characteristics of the introduced varieties and whether they can adapt to the local natural conditions. To consider the introduction of varieties of production performance, economic value and breeding value. Third, the correct choice of species 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. Fourth, carefully selected 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 should also be paid to the pedigree review, paying attention to the level of productivity of the parents and siblings and preventing 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. V. Reasonable dispatch 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. Secondly, it is necessary to do a good job in all specific tasks before and after the dispatch, including the disinfection of vehicles, the organization of personnel, measures to prevent the heat (warming and keeping warm) on the way, and the feeding system. It is better to carry some feed from the origin to Feed on the way or when you first arrive in a new area. Sixth, carry out adaptive exercise The introduction of livestock and poultry in the initial feeding and management is the key to success. In feeding and management, measures such as tree planting, scaffolding, and changing the structure of livestock and poultry shall be adopted in accordance with the climate and breeding habits of the country of origin to create a good breeding and management condition; the adaptive training shall be strengthened so that the introduction of livestock and poultry gradually adapts to the local nature. surroundings. The type of diet and feeding system should be gradually transformed so that the introduction of livestock and poultry can be adapted to local conditions as soon as possible. Prevention of endemic and parasitic diseases, so that the introduction of livestock and poultry living in the local health.
