Small Tail Han sheep new method of breeding two strokes
Small-tailed Han sheep are excellent sheep breeds for both flesh and wool. The seed sources are mainly distributed in Liangshan, Dongping and surrounding cities and counties in the western part of Shandong Province. It is praised by the industry experts as "the Chinese national treasure" and "the world's rarest sheep." It adapts to strong, rough feeding, large body (150-200 kg of adult rams), more lambs (2 to 4 lambs per baby, more than 7 lambs), high efficiency (an adult ew Yuan above). In recent years, most of the domestic cities, counties, Central Asia, Western Europe, Oceania and other countries have introduced breeding and feedback. Gastric lavage and fertilizer are new methods developed by the two farms that have successfully developed the small-tail sheep in recent years by the farm of the farmer in the Cangshan County, Shandong Province. It is convenient, practical and economical. It is very beneficial to its growth, reducing the cost of raising and increasing the efficiency of breeding. (A) small stomach Han sheep in feeding, it is difficult to avoid eating "pollution" drink "scale", so that the small tail Han sheep suffering from parasitic diseases, diarrhea or other diseases, is not conducive to normal growth, and even death. Therefore, gastric lavage at regular intervals (alternate January) helps prevent diseases and health. The method is to eat enough salt for small tailed sheep. Each time a sheep can eat about 0.2 kilograms, more than 0.4 kilograms more than the amount of food intake and weight are positively correlated. After 2 to 3 hours of dying, when physiological thirst, drink into gastric lavage water (that is, warm water or cool water, according to sheep's happiness, irritability and may be). Points to Note: (1) The time to eat salt should be selected in the morning when fasting. (2) Do not use diseased sheep to prevent injury to the stomach and spleen and kidneys. (3) The amount of gastric lavage should be sufficient. Each sheep should be no less than 10 kilograms. In order to make the sheep drink more, some wheat bran, corn flour or other light concentrates may be sprinkled in an appropriate amount. (4) Some farmers in more than one hundred trials across the country are skeptical of the breeders, simplifying the method of dissolving salt directly in the water to wash the stomach. The effect is not stable and it is inconvenient to promote it. (5) 15 to 20 minutes after drinking, chase the sheep for slaughter activities, promote its acceleration of blood circulation, wash up the body's "turbidity", "wash" the internal environment, increase the amount of excretion. To achieve the purpose of disease prevention and health. (2) For the use of small-tailed Han sheep (mothers), suitable fertilizers should maintain the functional capacity of their reproductive system in order to be able to reproduce quickly, multiply and multiply. Sheep's fat, too much muscle, hoop pressure fallopian tube, unfavorable egg discharge, pregnancy and implantation; too thin, small uterus, inadequate storage, impede the development of young fetus, the formation of aberrant fat, stillbirth, reduce the reproductive rate. Therefore, it is necessary to make the fat lean and apply proper fertilizer. The method was to breed the ewes 45 days later and then quickly finish fattening for 15 days. After that, the raw material was drastically reduced, the raw material was suddenly increased, more water was consumed, and nutrition was reduced. To promote the ecstatic physiological phenomenon of the euchaemia, the reproductive system is active, and the estrus can be established as early as possible, and the breeding can be improved. Points to Note: (1) The fertilizer season should be in spring, summer and autumn. Not suitable in winter, it will hinder the growth of the ewes and affect the breeding efficiency in the following year. (2) Suitable fertilizer time should not be too long, limited to one week. (3) Non-disease, weak, disabled, and inferior sheep are suitable for fertility. (4) The method of applying fertilizer is slightly different in different regions. (1) Grazing areas such as the northeast and northwest can appropriately increase the amount of concentrate and reduce the amount of ewes. (2) In North China, East China, and other areas, generally combined with half of the nutrients contained in the fine and coarse materials can be fed. (3) Central China, South China and other areas can reduce the amount of concentrate and increase the amount of ewes exercise.
