First, manage the sheep house: In the summer, the sheep house should do the work of cooling the sun. If the sheep shed is a flat tile roof, white lime can be brushed or sunshades can be placed on it; air convection windows can be found at the bottom of the south and north walls of sheep sheds; the awning canopy can be installed on the sun-facing side of the sheep house. In addition, the sheep house should also be equipped with screen doors, screens, to prevent the entry of flies and mosquitoes. Whether it is a flat raising method or an elevated method of raising sheep, in order to prevent the waste of forage grass, it is necessary to set a feed trough.
Second, increase the intake of food: Increased intake is to ensure the good sensation of the sheep, especially in the hot summer season, because the sheep's feed intake decreased, increasing the number of feeding, it has become the main method to reduce and prevent heat stress. If the intake of the sheep is hindered, the high nutrient concentration of the feed does not guarantee the health of the sheep and normal production.
Third, enhance nutrition: In the summer, it is necessary to strengthen the nutrition of the sheep, increase the nutrient concentration of the diet, and properly supplement the mineral bricks to further enhance the sheep's resistance to the high temperature environment. In adult sheep, 200 grams of supplemental concentrate is provided each day; the newly weaned lamb is replenished with about 100 grams of concentrate every day. For each hundred grams of concentrate, the cakes should account for 25%. If adding cotton cakes or cakes, they must be detoxified: soaked in water for 24 hours and rinsed with fresh water.
Fourth, feeding good forage: In the summer, sheep should be selected for good palatability, high nutritional value of pasture (such as green bean stalks, alfalfa, etc.), especially the lambs weaned and pregnant ewes need to pay attention to this point. Feeding forage should be dry and green, and hay is the best choice for hay, hawthorn vines and peanuts. When feeding, feed grass after feeding hay to prevent sheep from eating too much and overeating pasture with high water content. Produce diarrhea and bloating disease. In addition, do not feed with mildewed forage grass feed.
Fifth, grazing night feeding: For grazing sheep, to implement early and late grazing, before 9 o'clock in the morning, the sheep must return to rest; after 5 o'clock in the afternoon to go out grazing. In the summer, the best night feeding is implemented. The feeding time should be about 10 o'clock in the evening. It is not good for the sheep to rest and digest when it is too late. Pay attention not only to the amount of feed but also to the quality.
Sixth, increase water to make up salt: summer is a hot season, should keep the sheep's water basin constantly clean water, let the sheep drink freely. Add 0.2 grams of salt per kilogram of body weight to maintain the body's acid-base balance.
VII. Summer cooling: In summer, especially in summer cooling work, pay attention to the shade, avoid direct sunlight, while taking shearing, strengthen ventilation, in order to facilitate the heat of the sheep's body surface.
8. Resting and increasing resistance: In the summer, it is necessary to create a stable environment and playground environment suitable for sheep to rest, so that the sheep can maintain the physiological function of the body only in a high-temperature environment, enhance the resistance, and maintain normal production.
Nine, pest prevention and deworming:
1 immunization. In the pregnant ewes 20-30 days before and 10-20 days before the onset of labor in the hind leg subcutaneous injection of two lambs dysentery formaldehyde vaccine 2 to 3 ml, can prevent lamb dysentery. Sheep who have not been injected with the W (foot-and-mouth disease) vaccine or the sheeppox vaccine must be recharged.
2 regularly deworming. After entering the summer, the goats are injected with avermectin, 0.02 ml per kilogram of body weight to drive off the parasites in the body and the other, and a regular injection of mutated anaerobic disease.
Ten, prevention and treatment of diseases:
1 Prevent diarrhea. When sheep are diarrhea, they can be treated with oral gentamicin on an empty stomach in the morning. Two 80,000 units of gentamicin can be used for 2 days.
2 Prevention of sheep sores. When a sore occurs, the wound is washed with 0.1% to 0.2% potassium permanganate solution and then coated with 2% gentian violet, sulfoglycerol, 50% oxytetracycline ointment or penicillin, nitrofurazone ointment, etc., once or twice a day. Usually use less hard feed to prevent wound infections, and timely isolation of diseased sheep found. Shelters and utensils are disinfected with 2% caustic soda or 10% lime milk or 20% of planted grey water.
3 summer anti-black disease. When a sheep has a black blight, it is necessary to move the sheep's collar to Gaozao, and use the serum against Clostridium novyi early to prevent subcutaneous or intramuscular injection of 10 to 15 ml. For the disease-stricken goats, 800-160,000 units of penicillin were intramuscularly injected twice a day; intravenous or intramuscular injections of Clostridium novyi clostridial serum, each 50-80 ml, were used twice.
