Duck introduction matters needing attention
The introduction should be based on the needs of the production or breeding work, determine the type of species, at the same time to examine the economic value of the cited species. As far as possible, the introduction of fine varieties that have been expanded in the country can avoid certain drawbacks introduced from abroad. Before introduction, we must first understand the technical data of the introduced varieties, and have sufficient understanding of the introduced varieties' production performance and feed nutrient requirements. If they are purebreds, they should have appearance characteristics, breeding history, genetic stability, feeding and management characteristics and disease resistance. For introduction after reference.
2. Pay attention to the adaptability of imported varieties
The selected introduced species should be able to adapt to the local climate and environmental conditions. Each species is formed under specific environmental conditions and has special adaptability to the place of origin. After being introduced into a new area, if the environmental conditions in the new area differ greatly from the origin, the introduction will not be successful. Therefore, the introduction must first consider the differences between the local conditions and the conditions of origin; secondly, consider whether Provide suitable environmental conditions for the introduction of varieties. Thoughtful, introduction can be successful.
3. Introduction channels should be formal
Introducing from a regular duck farm can ensure the quality of ducklings.
4. Must be strictly quarantine
It must not be introduced from the diseased area to prevent disease during introduction. The animals should be kept strictly isolated before entering the market, and they can enter the site only after they are confirmed to be free of disease.
5. Must be prepared in advance
Such as housing, feeding equipment, feed and utensils, etc. should be prepared, the breeder should provide technical training.
6. Note the introduction method
(1) The number of varieties introduced for the first time should not be too much. After the introduction, the performance of 1 to 2 production cycles should be observed first. When confirming that the introduction effect is good, the number of introduced seeds should be appropriately increased to expand breeding.
(2) When introduced, young birds that are healthy, have normal development, are free of inherited diseases, and are underage should be introduced because they have strong plasticity and are easy to adapt to the environment.
(3) Pay attention to the introduction season. The best choice for introduction is in the season when the climate of the two places is not so different, so that the introduced individuals gradually adapt to the changes in the climate. Introduced from the cold zone to the tropics and introduced in the fall, the introduction from the tropics to cold regions is best introduced in late spring and early summer.
(4) Do a good job of organizing transportation organization, avoiding the affected area, and shorten the transportation time as much as possible. If the transportation time is too long, it is necessary to prepare for drinking and feeding on the way to reduce the loss on the way.
Plant extracts refer to substances extracted or processed from plants (all or a part of plants) using appropriate solvents or methods, and can be used in the pharmaceutical industry, food industry, daily chemical industry and other industries.
There is a conceptual overlap between plant extracts and herbal extracts. The raw materials of plant extracts in my country are mainly derived from Chinese herbal medicines, so domestic plant extracts can also be called Chinese medicine extracts to some extent.
