“Nanjiang Yellow Sheep on the market now sells 20 yuan per catty. I would like to breed without fear of failure in technology. Can you help me?†On May 15, the reporter interviewed Wushan Miao Village, Gaoqiao Township, Nanjiang County. A farmer friend said urgently. The reporter Geng interviewed Jia Zhenggui, a livestock researcher of the Nanjiang County Animal Husbandry Bureau. Jia Zhenggui said that it is not difficult to keep Nanjiang Yellow Goat. It is important to grasp the following five points: The construction of Nanjiang Yellow Sheep in pen homes is relatively large, and it is generally advisable to raise 1 sheep per square meter. Lambs can be kept 3 to 4 per square meter. only. The sheep house should be built in sunny areas, leeward, dry and water sources, where grazing is convenient. The sheds are required to be located north to the north, cool in winter and cool in summer, well ventilated and well lit. The building area is 1.5 to 2 square meters for each kind of ram, and each of the reserved sheep, eliminated sheep and mutton is 0.6 to 0.8 square meters. The sheep house is preferably a house-style sheep house, preferably in a place with a slope of 25 degrees. Generally, the height of the bottom of the fence is 1 to 1.5 meters above the ground. The bottom of the fence is covered with bamboo or wooden sticks with a smooth flat hairless spike with a pitch of 1 to 1.5 centimeters. The total area of ​​the windows is no less than 1/15 of the area, and the south window should be large, accounting for 2/3 of the light passing area. The sheep house shall have supporting facilities such as troughs, grass racks, sinks, medicine baths, forage grass and fodder rooms, micro-reservoir pools, mother and child pens, species of ram pens, and sports fields. Grazing requires scientific planning to select grazing land. Grazing land generally requires drying, sunny, green grass and shrubs mixed, rich water, good water quality. According to the quality of pastoral land, if grasses and shrubs are more luxuriant, it usually takes 300 square meters of grass for an adult sheep year, and 600 square meters if it is not. Adhere to grazing. Grazing time is generally after 8 am, choose rich pasture, Xiangyang grazing plan to implement the rotation, generally every 1 week for a place, each pasture should generally rest and grazing half months before re-grazing. In doing so, it is beneficial to the growth of pasture on the one hand and beneficial to the control of pathogens on the other hand. Grazing grazing is the first step to be taken when grazing. That is, males and females are divided into lambs, bred sheep, adult sheep, and mutton sheep. Generally, about 100 are large groups, 50 are medium groups, and 30 are small groups. If breeding sheep, it should also be based on species of rams, basic ewes, reserve rams, mutton sheep and out of sheep groups, species of rams to Zhongqun is appropriate. Second, we must adopt flexible grazing. There are five kinds of flexible grazing: 1 The Gypsophila: The sheep are evenly distributed, and the sheep are allowed to feed freely without restriction, which is mostly used for the abundant grazing season and the hot summer season. 2 A whip: arrange the sheep into a horizontal team, and the grazing staff control the forward speed of the sheep one after the other to prevent dispersal and left behind on both sides, mostly in the first season of grass. 3 Waiting for the release: After the grazing clerk catches the sheep up to the road, they can take shortcuts to the end of the flock where they are scheduled to wait for herds to be grazing. They are mostly used in grassy or dry seasons. 4 Partition grazing: The grazing land is divided into a number of plots, and the grazing is played back in a certain order. This method is a good economic and practical method. 5 Holding and holding: It is mostly used in scattered pasture land. Differences in grazing in the four seasons: Spring: To prevent the sheep from running around and prevent pregnant ewes from abortion. Sooner or later, we should add some hay, so that we can achieve the grazing method of “going slowly, going uphill, staying in the middle, etc. and returning to the pastâ€. Summer: Keep sheep in the morning and at night. Let the sheep rest in the shade or in the house at noon; put the western slope in the morning and the east slope in the afternoon to prevent sun exposure and heavy rain. In the evening, when the herds in the sheep's house emit heat, they are rushed to the house. In the fall, the method of “grazing as usual with light rain, insisting on grazing with moderate rain, catching heavy grazing with heavy rain, and grazing immediately with rain stopped†and the method of setting up for a sunny day and a long day for farrowing. Winter: Choose sunny slopes and grazing in lower grazing areas, pay attention to keeping warm, keeping warm, and protecting fetuses. At the same time, regardless of the spring, summer, autumn and winter, 5 grams of salt per sheep should be placed on a clean slate to allow the sheep to feed freely. Doing a good drinking of water and drinking clean water, the sheep will not let you drink stagnant water, sewage. Feeding and lambs are fed with appropriate feeds. In the breeding season, when the rams are in the peak period of breeding, they must supplement the concentrates properly. The sheep must concentrate and fatten it within 2 months before slaughter. Generally, each sheep feeds 50 grams of soybeans and 250 grams of wheat bran every day to ensure its nutritional needs for growth and reproduction. Lamb feeding. (1) The newborn lamb should allow him to eat early and eat more colostrum (ie milk within 7 days after delivery). In the first month after birth, the lamb should be fed with regular milk, and many lambs should be artificially supplemented with milk, and 3 milk supplements should be maintained for 1 kg or more per day. (2) After the lamb was born for 10 days, it was bred with tender grass and mixed condiments and allowed to eat grass as early as possible. Start feeding at 20 days of age. The initial feeding should be soft, digestible, and feed containing high starch content. Do not feed high fat-containing feeds such as beans. Mixed concentrates generally require a protein content of not less than 20% and a crude fiber content of no more than 6%. (3) Grab the lamb movement and grazing. 10 days after birth, the ewes can be grazing from near to far away. (4) Grasp the weaning of the lamb. Lamb weaning period is generally 2 months old, weighing about 10 kilograms. Good male rams that are poorly developed and reserved for seeding can be appropriately prolonged. The timely mating of Nanjiang Huangyang can be used for mating at 4 months of age, so it is important to pay attention to the activities of the sheep and to find out that there are estrus ewes. The best breeding or artificial insemination should be performed in time. Lambs should be promptly weaned to promote estrus in the ewes. If necessary, triad hormones, human chorionic gonadotropins, and other drugs can be used for artificial aphrodisiac breeding to increase fecundity of the ewes. Disease prevention and epidemic prevention and disinfection. Each adult goat is injected with 3-5 ml of foot-and-mouth disease inactivated vaccine in deep muscles. After the first immunization, the vaccine is boosted again 3 to 4 weeks later. After that, it can be injected once every six months. Usually with 0.5% fire alkali solution or 15% -20% quicklime milk on the barn, venues, utensils and disinfection pools, such as regular disinfection, disinfection can be generally 1 to 2 times a week. Flocks should be kept out of contact with the population. In particular, each sheep farmer should not cross the door. Visitors must also be strictly quarantined for visits. Shepherds must not go to the affected area, and they must not go to the affected area for grazing. Disease prevention and control. Adhere to the principle of prevention, prevention and control. In summer and autumn, an ectoparasite is killed every month. In the winter, "three-joint seedlings" or "four-joint seedlings" were injected. Three days after the lambs were born, they were injected with Lamb Poultry or oxytetracycline at a dose of 10 to 15 mg per day for 3 consecutive days to reduce the incidence of disease. Control of nematodes (Pneumothorax), aphids, etc., and ectoparasites (aphids): can be controlled using the "Bergstar" series of highly effective and low-dose insecticide drugs produced by Beijing North Agriculture Luheng Technology Development Co., Ltd. Kg weight 0.3-0.4 mg. One dose is given once a week after the administration to consolidate the curative effect. For the prevention and control of schistosoma (mainly hepatic larvae and double worms): the effect of "liver cirrhosis" or thiophanate-imidazole is very good, and the drug is generally used. The amount is 0.1 to 0.5 mg/kg body weight, safe and effective.
