In summer, the weather is hot and the temperature is high, especially in the “three volts†days. If sheep are poorly reared and managed, sheep are prone to heat stroke. In addition, the hot weather, the sheep's appetite is often not good, easy to fall out. Therefore, it is very important to do a good job of feeding and managing sheep in summer.
First, the construction of housing. When building a sheep house, it is best to face southwards. It is necessary to ensure that the fences are spacious and well-ventilated. Pergola or trees are shaded to avoid overheating of the environment. The materials selected for the roof insulation are better and the insulation properties are better. It is advisable to add cooling facilities (such as fans, shading nets, sprayers, water spray equipment, etc.), and to increase artificial cooling at noon to evening hours to ensure air convection. The sheep house is equipped with screen doors and screens to prevent mosquitoes from entering the flies and keep the sheep house clean and dry.
Second, reduce the breeding density. In the hot summer season, sheep should be kept at a reasonable rearing density. It is advisable to have an area of ​​about 2.5 square meters per sheep.
Third, timely shearing. The physiological characteristics of the sheep are relatively cold and heat-sensitive, so timely shearing is very important for the protection against heat of the sheep. Due to the great climate differences in China's sheep-raising area, the shearing time is not the same. For example, sheep are fed in Hebei, and it is best to cut wool in April-May when the climate is stable. Fine wool sheep and semi-fine wool sheep only cut 1 spring fur each year; coarse wool sheep also need to cut 1 autumn fur in August-September. If you do not consider the use of wool, sheep that have been sheared in the spring can be sheared again before July 25th, which has a huge effect on the prevention of sheep's heatstroke.
Fourth, adjust the feeding time. Early and late feeding is performed before 7 o'clock in the morning and after 6 o'clock in the afternoon.
Fifth, increase feed nutrition. Use forage grasses with good palatability and high nutritional value to feed green and blue juicy feeds; adjust diet formulas to ensure proper nutrition and increase energy and protein levels in the diet; supply sufficient cool drinking water; meanwhile pay attention to supplements A certain concentration of feed, with particular attention to the addition of trace minerals and vitamins. The newly weaned lambs and pregnant ewes need nutritional supplements.
Sixth, prevent diseases. Do a good job of sheep house disinfection, eliminate mosquitoes and flies, and prevent flies and mosquitoes from affecting sheep rest. Forage grass with green, to avoid eating too much high moisture content of the sheep and diarrhea and bloating, feeding should use hay, when feeding, first fed hay after feeding grass. Lambs can be treated with antibiotics such as gentamicin.
After the heat stroke, put the diseased sheep in a cool and ventilated place, and apply cold water to the head or enema with cool water; rehydration and rehydration, while intravenous injection of physiological saline or sugar water 500 to 1 000 ml. Excited sheep can be intravenously injected with 2 ml of Jinglingling. If necessary, they can take cool and stomachic medicines such as gentian, rhubarb, artificial salt and peppermint water.
Seven, pay attention to transport time. Avoid transporting sheep in the hot summer or long distances. If you really need to transport, you must avoid high temperature, choose to transport at night, but also pay attention to cooling.
