Due to the gradual cold weather, grasses decreased, grass quality deteriorated, and nutrition decreased. Many farmer-raised sheep become skinny. In order to protect the sheep, the following key points should be grasped.
Reasonable grazing
After entering the winter, some cold-tolerant plants can be used to feed the sheep. After the ice on these plants is dissolved and sun dried, the sheep will be grazing immediately. At night, try to return late at night and do not rest at noon so that the sheep can eat and eat well. Grazing land should be selected on the slopes, creeks and other places where the terrain is low and the leewards are sunny. The rain and snow temperatures are low, try not to grazing and reduce sheep movements to reduce physical energy consumption.
Adequate forage
Each adult sheep has 400 kg of hay reserves in the winter and hay reserves can be used to store a variety of crop straws and feed herds with silage, micro-storage, dry powder wet mixing and other methods. At the same time, according to the number of sheep in the fall, 2 acres to 3 acres of high quality and high yield of clover, ryegrass and radish, to the sheep to do the winter feed to ensure that the sheep have sufficient high-quality fresh grass feeding in the withered period.
Reasonable grouping
After winter, according to the sheep's age, sex, physique, etc., the sheep are grouped rationally, and a group of sheep with similar body condition and strength are grouped together and reared in groups so as to take care of the weak lambs. In the winter, the flock should be maintained in good weather and grazing plus supplementary feeding methods. Rain and snow weather must be maintained throughout the day. For the poor quality, long-term empty and low performance sheep should be eliminated in time, fattening market.
keep warm
In winter, the sheep consume more heat, so we must keep warm. After winter, it is necessary to thoroughly inspect the pens, such as the walls, especially the walls in the north, so that they can be repaired and made airtight. The ventilation holes around the sheep pen should be blocked in time so that the temperature in the circle can reach 10°C or more.
Timely feeding
In winter, the weather is cold, the grass is rough, and the flock has many difficulties. In particular, pregnant ewes not only need nutrients themselves, but also the fetus needs nutrition to grow and develop. Grazing alone can not meet the nutritional needs of the sheep. The only measure is to feed the sheep with some corn, wheat, radish, etc. supplements. In winter and spring, it is necessary to properly match with forage grass, and supply it twice in the morning and evening. In the feeding of forage grasses, the method of combining first and later green varieties, and feeding fewer meals and adding them in a timely manner ensures that the sheep have sufficient, palatable, and more comprehensive feed for forage grasses. In terms of feeding amount, the amount of hay on the day should account for 6% to 8% of their own weight, and the amount of green fresh grass should account for more than 20% of their own weight. In order to increase the amount of feed, regular spraying of brackish water on forage grass can be used to make the sheep The belly is full of belly all day. In order to improve the fattening effect, 1%~2% of body weight can be supplemented with fine material. The formula is the proportion of fine material per 100 jins: 64 pounds of corn, 15 pounds of fried beans or cakes, 18 pounds of wheat bran, and salt 1 kg, 1 kg of urea, and 1 kg of Twelve Almighty Additives. Crush and mix evenly, and feed quantitatively every night. There must also be sufficient clean drinking water for the sheep. In this way, the average monthly weight gain of mutton sheep can reach 12 pounds or more, and the maximum weight can be more than 20 pounds.
Do a good job of prevention
While paying attention to keeping the sheep's house clean and dry, it is necessary to do a good job of preventing the epidemic of the sheep by triple inactivated vaccines such as sheep pox, sheep contagious pleuropneumonia, sheep epidemic disease, delirium, and enterotoxemia. Second, we must do a good job of the parasites in the flock. Insecticides can be administered by oral immunization with 12.5 mg to 25 mg per gram of body weight or levamisole and 10 mg per kilos of body weight per kilogram of body weight. Once every 7 days, the insecticide can be used to achieve an ideal insect repellent effect.
Due to people's concerns about health, plant products from natural sources have also received widespread attention. Natural plant tea cuts are products made by direct shearing, crushing, and other physical processing of pure plants. The product retains all the original characteristics of the plant, and the properties of the product are better packaged and can be easily transported to different places.
At the same time, the active ingredients of the product are not damaged. It is widely used in functional tea and other fields. Common products are: astragalus cut, burdock cut,etc.
