The abundant forage grass in spring and summer is a great opportunity for meat sheep to grazing. However, hot weather in summer can easily cause sheep to suffer heat stroke or cause other diseases. Therefore, farmers should adjust measures to local conditions and scientifically stocking them in order to achieve superior sheep breeding and rapid fattening.
First, to the sheep anthelmintic bath. Adult sheep and postpartum ewes can use the novel anthelmintic aforein (insect nemesis) to drive off the internal and external parasites before mid-May. Dosage: 50 kg body weight with 5 grams of insect star, mixed feed in the feed. Repeat dosing every 7 to 10 days. Lambs produced in the spring may be treated with nitrate-nitrogen powder, etc., according to their medicinal indications, where the epidemic of schistosomiasis is endemic.
Second, pay attention to sheep house reconstruction. The sheltered high-strip zone should be selected to maintain ventilation and facilitate the cleaning of excreta. The height of the sheep house should be kept at about 2 meters to achieve waterproof, ventilation and heat insulation. There must be a certain slope at the entrance, but it must be leveled so that the soles of the feet are plain when the sheep enters and exits.
Third, scientific grazing. Hot weather in summer, early grazing in the morning should be early to return, the general dew just dry to grazing. From 11pm to 3pm, the sheep are allowed to rest in the laps to graze. In the afternoon, they can graze at 7pm. In sunny weather, dry places should be selected for grazing; large hot days should be selected for grazing in the dark forest to prevent heat stroke.
Fourth, pay attention to salt water supply. When replenishing 1 to 2 batches of feed (dairy bran, cornmeal, bean cakes, etc., plus rice bran, and grasshopper) daily, the sheep are grazing every day as long as they drink 4 to 6 dilute brines. Do not allow the sheep to drink dead pond water, drain water, ditch water or let the sheep graze in moist and muddy places to rest, so as not to cause rheumatism.
Fifth, prevent wind and rain attacks. Thunderstorms are more frequent in summer, and once the flock is attacked, it is very easy to injure the body, catch a cold, and fall. Therefore, summer grazing should be avoided as much as possible. In rainy weather, when grazing, you can bring large pieces of fiber cloth that can hold the flock. The four corners are fastened on the roots of the big tree, and the middle is lifted with a thick wooden stick to allow the sheep to temporarily shelter from the rain. In addition, avoid lightning and thunder when grazing on steep slopes to prevent sheep from being hurt.
Six, pay attention to cooling body. Summer sheep can easily get angry. Therefore, it is very important to cool sheep every day to ensure the health of the sheep. After a long period of grazing, sheep often cause fatigue and sultry, and it is easy for the sheep's stomach to get sick. Don't rush into the sheepfold at noon to graze the flock. You can let the sheep cool down and drink under the shade of the trees. After grazing in the evening, the sheep can be kept in the shed for a period of time. Do not hurry to chase the sheep each time you are grazing and gathering. You should let the sheep walk slowly, move, and cool.
Seven, do a good job in environmental health. In summer, when the animals are hot and humid in the summer, the sheep's grazing returns and the range of activities becomes smaller, which may cause moisture and environmental problems in the pens, which may cause parasites. Therefore, attention should be paid to the environmental sanitation, ventilation, and moisture-proof of the sheep houses to keep the sheep houses clean. Dry and cool. Daily feeds and drinking water must be kept clean. Do not feed molds, spoilage, poisonous, and inclusions. Feeding utensils are often kept clean. Sheep farms and sports fields should be cleaned regularly and regularly disinfected.
Eight, prevention and treatment of diseases. Regular injections should be made. Injections should be taken seriously, and inventory should be made on a case-by-case basis. Always pay attention to the sheep's state of mind, appetite and feces when grazing. Pay special attention to the disease prevention and control of the lamb. General lambs should be given oxytetracycline 10 mg within 36 hours of birth, 2 times a day, even for 3 days, can reduce the incidence of disease. (1) timely injection of foot-and-mouth disease, goat pox and quadruple vaccine (Anthrax, fast-food, goat pox, sheep enterotoxemia). (2) Lamb dysentery. With sulfa 0.5 g, sodium bicarbonate 0.2 g, 1 oral, and even served 3 times, or penicillin 5 to 100,000 units, intramuscular injection twice daily. (3) Lamb pneumonia. Intravenous injection of 10% sulfadiazine sodium 5 ~ 10 ml, plus 25% glucose solution 20 ~ 30 ml. When an infectious disease or suspected infectious disease occurs, it should be immediately quarantined. The veterinarian should be observed and treated in a timely manner. The corpse of the dead and dead sheep must be properly handled, buried or burned, so that the source of the disease can be cut off, and the epidemic can be controlled and extinguished in time.
