What problems should be paid attention to in the introduction of sheep?

(agricultural get Rich Network) what problems should be paid attention to in sheep introduction? -1 adaptation of climatic environment the producing area of small-tailed Han sheep, ─, is located in the Yellow River impact plain, 500m above sea level, with a suitable climate, with an annual average temperature of 13.6 ℃, an absolute maximum temperature of 40 ℃, an absolute minimum temperature of-18 ℃, an annual precipitation of 749mm and a frost-free period of 206 days. Because of its specific climatic environment, the adaptability of climatic environment must be considered in introduction. Xiao Yongli reported that the climate in the south is generally hot and humid, and it is often difficult for small-tailed Han sheep to adapt in hot summers. in addition, in case of rainy and wet weather, rough hair is easily contaminated and wet is not easy to dry. it often leads to diet, elevated body temperature, cough and other cold symptoms, but also easy to cause acariasis, spread sheep, difficult to cure. In this case, the incidence of small-tailed Han sheep is frequent, often acute, short course of disease, difficult to cure and high mortality. Small-tailed Han sheep showed good ecological adaptability in the southern alpine region (Bijie, Guizhou). According to many regional reports on the introduction of small-tailed Han sheep, small-tailed Han sheep can adapt well even in some high altitude areas (1800-2940m), but these reports often adopt suitable feeding methods and give them adequate nutrition. Therefore, in the introduction, we must consider whether the local climatic environment is suitable for raising small-tailed Han sheep, do not introduce blindly. -- 2 after the introduction areas and the quality of the species caused small-tailed Han sheep fever throughout the country, a considerable number of governments, collectives, individuals, as well as many enterprises and institutions all over the country went to Shandong and other producing areas to compete for introduction. As a result, the number of improved varieties in producing areas has been greatly reduced, and the supply falls short of demand. In this case, some individuals and collectives, motivated by interests, bought sheep from outside the producing areas many times and hybrid sheep pretended to be good breeds of small-tailed Han sheep for sale, and even individual people bought back the hybrid offspring of the introduced breeds in the introduced areas for sale. some people use other breeds of sheep to pretend to be small-tailed Han sheep, resulting in a mixture of good and bad small-tailed Han sheep. Therefore, in many areas, after introduction, it is found that the production performance of the bought sheep is far from the introduction or report. Therefore, the introduction must be from the place of origin or from a relatively close area with high quality germplasm. In the introduction, it is necessary to have a certain understanding of the appearance characteristics of small-tailed Han sheep, so as to avoid the introduction of other breeds of secondary sheep. At the same time, it should be introduced from the small-tailed Han sheep breeding farm or through the local animal husbandry management department. (3) the reasonable feeding method after introduction is rich in forage resources and superior feeding conditions in Shandong, Henan and other small-tailed Han sheep producing areas. Small-tailed Han sheep are scattered in farm households, adopting house feeding and semi-house feeding, and the grazing distance is short. And often, when farmers are working in the fields, they tie the small-tailed Han sheep to graze in the fields and bring them back when they are finished. Breeder sheep are generally raised by house feeding. However, after introduction, many areas did not take into account the way of feeding in the place of origin, but changed to the way of grazing. Small-tailed Han sheep have a serious phenomenon of "running green" when grazing, often taking a bite, looking at it, running a few steps, and eating another bite. In this state, all the nutritional energy of the body is consumed by "exercise". The origin of small-tailed Han sheep is plain, and after grazing is adopted after introduction in many mountainous areas, small-tailed Han sheep are not good at climbing hillsides because of their high legs, so grazing on the hillside is very easy to slip. It can be seen that the inadaptability of feeding methods has greatly affected the production performance of small-tailed Han sheep. Therefore, a reasonable feeding method must be adopted after introduction, and it is suggested that house feeding or semi-house feeding should be adopted. house feeding and short-distance grazing can be combined organically in areas with conditions, and house feeding must be adopted in mountainous areas. to avoid losses caused by unreasonable feeding methods. -- 4 the intensity of organization and management after introduction is not enough and utilization is insufficient in many introduction areas, only pay attention to introduction, but ignore the organization and management after introduction, lax management, weak measures, less follow-up investment, lack of necessary guidance, resulting in low utilization rate of sheep after introduction. This factor is mentioned in many reports about the poor effect of small-tailed Han sheep after introduction. It can be seen that the importance of the follow-up management work after introduction. Therefore, after the introduction of the collective organization, we must strengthen the organization and management, through a series of effective measures, organize farmers to raise scientifically and make rational use, so as to achieve the desired purpose of introduction. In a word, there are many problems that should be paid attention to in the introduction of small-tailed Han sheep, which are discussed in this paper. In the recent period, the small-tailed Han sheep entered the stage of sustainable development. At present, domestic mutton sheep are popular, and mutton sheep production is carried out in many areas through the introduction of small-tailed Han sheep. I hope this paper can provide reference for the majority of introduction households. -- pass by, pass by.. Don't miss it.-- look.-- pass by, pass by.
