Among the natural ecological factors, temperature is the most important ecological factor for sheep, which directly or indirectly affects the performance and production performance of sheep. When the ambient temperature is too high or too low, the body temperature of the sheep begins to rise or fall, and eventually heats up or freezes. When the summer temperature is high, the feed intake of the sheep is reduced, and even the feeding is stopped, and the sheep tend to fall off. Especially at high temperatures at noon, there is often a phenomenon of wheezing, the body temperature rises, the heart rate increases, the respiratory rate increases, and heat stroke and even death occur. Therefore, the author suggests taking the following six measures to ensure that the flock is safe in summer and prevent it from falling out.
Heatstroke prevention
Summer should be done to prevent heatstroke and cool down, often remove the weeds around the sheep house, open air convection windows at the bottom of the south and north walls of the sheep house, strengthen ventilation; set the sunshade on the sunny side of the sheep house to avoid direct sunlight; if the sheep house is flat tile roof You can brush white lime or cover the sunshade; increase the green area around the sheep house and improve the microclimate.
Strengthen nutrition
Regardless of the cold season in winter and spring or the hot season in summer and autumn, it is necessary to strengthen nutrition, increase the nutrient concentration of the diet, and further enhance the sheep's resistance to high temperature environment.
Feeding high-quality forages Choose forages with good palatability and high nutritional value, such as green bean stalks and alfalfa. Especially the newly weaned lambs and pregnant ewes need to pay more attention to this.
Supplemental concentrate
Adult sheep feed about 200 grams of concentrate per day; freshly weaned lambs feed about 100 grams of concentrate per day. In every 100 grams of concentrate, the cake should account for 25%. If it is added to cotton cake or cake, it needs to be detoxified. Method: Soak in water for 24 hours, then rinse with water.
Feeding salt
0.2 grams per kilogram of body weight to maintain the body's acid-base balance.
Increase drinking water
During the hot season, ensure that the drinking water is adequate and cool, so that the sheep can drink freely and inhibit the temperature rise of the sheep.
Increase intake
Increasing feeding is to ensure the good sensation of the sheep, especially in the hot summer and autumn seasons, because the sheep's feed intake decreases, increasing the number of feeding, it becomes the main method to reduce and prevent heat stress. If the feeding of the sheep is blocked, the higher the nutrient concentration of the feed does not guarantee the health of the sheep and the normal production. Also, don't feed on the bad forage.
Suitable management
Feeding or grazing in the morning and evening to adjust the feeding time, feeding in the morning and evening when it is cool, try to avoid feeding at noon. Or the implementation of early release and returning to grazing, before 9 o'clock in the morning, the sheep must go to rest, go out to graze after 5 o'clock in the afternoon, try to avoid the noon time grazing.
Night feeding
This material should not only have the quantity but also the quality. The feeding time should be around 10 o'clock in the evening. It is not good for the sheep to rest and digest.
Setting the trough
Whether it is a flat or elevated method of raising sheep, in order to maximize the feeding of the forage to the sheep and to prevent the waste of forage, a trough must be provided.
Forage grass with green
In order to prevent the sheep from eating and eating excessively high moisture, the diarrhea and bloating diseases are caused by the grazing and bloating. The hay should be matched with green hay, hawthorn vine and peanut vine. When feeding, feed the hay first. Feed the grass.
Shearing can be done to help the heat dissipation of the sheep's body surface.
Keep the house
Clean the feces at least 2 times to 3 times a day, disinfect 3 times to 4 times a month, and do a good job of eliminating mosquitoes and flies.
Guaranteed rest
It is to create a circle environment and a sports field environment suitable for sheep rest, so that the sheep can maintain the physiological functions of the body in a high temperature environment, enhance the resistance and maintain normal production.
Prevention and treatment of diseases In the summer, while doing the above five managements, it is also necessary to strengthen the epidemic prevention work to prevent the sheep disease from being a mass or local epidemic.
Regular deworming
In summer, the sheep were injected with avermectin at a rate of 0.02 ml per kilogram to remove parasites from outside the body.
Prevention and treatment of diarrhea
When the sheep is diarrhea, you can take 2 80,000 units of gentamicin in the morning on an empty stomach, and even take 2 days.
Vaccination
Sheep that have not been injected with W vaccine or sheep pox vaccine must be refilled with vaccine.
