The most suitable growth temperature for dairy cows is 4-24°C. High summer temperatures are also a season for the proliferation of microorganisms. Grasses are difficult to keep fresh, and silage and hay are susceptible to mold deterioration. Dairy cows are prone to mold poisoning or other digestive diseases. Therefore, it is said that summer cows are difficult to keep. However, as long as the measures are in place, cows can still be raised in summer. 1. Adjusting house temperature When the summer temperature is high, you must first open the barn door and window to increase the air flow in the house; secondly, use well water to wash the manger, ditch and walls; third, install an electric fan to evacuate the cows. The distance between the cattle bed is not less than 120 cm, and the cattle body is directly showered to absorb body heat and cool off. 2. Attention to lowering the humidity The cowshed must be kept dry, with no accumulation of water, and the ventilation in the house should be good, so that the relative humidity of the cowhouse and calf is controlled below 80%. 3. Adjust dietary nutrition The green feed and concentrate feed for dairy cows in summer should be “less and more refinedâ€, that is, the energy, crude protein and other nutrients in the feed should be more, but it should not be too high, and there must be a certain amount of Crude fiber. The amount of feed for summer concentrates will increase by 20% over the usual period. If soybean cakes are fed normally, they will account for 20% of concentrate feed and increase to 25%-30% in the summer. 4. Improve the feeding method to properly increase the number of feeding, or increase the night feeding, or condiment to congee, so as to make up for the lack of eating due to high temperature anorexia and increase milk production. 5. Filling enough cool drinking cows to drink enough water will reduce appetite, not only affect the milk production, but also to make the mucous membranes dry cows, reducing the cow's resistance to disease. Insufficient drinking water for a long time can cause metabolic disorders in dairy cows and even cause death in severe cases. Milk cows can drink 3-5 times the daily amount of milk, and it is better to let cows drink water freely in summer. 6. To build shelter shade In the hot summer days, in order to avoid direct sunlight, the cows can be raised or rested in the shelter. The ideal pergola is long, short, north and south, single slope top, south lower north, high shed 2.8-3 meters, surrounded by good ventilation, the formation of air draft convection in the house to reduce the temperature of the cowhouse. You can also put calves in the shade. 7. Doing a good job in sanitation In summer, due to the high temperature, the growth and reproduction of pathogenic microorganisms are also relatively active. Therefore, we should do a good job in environmental sanitation and strengthen prevention and treatment of epidemics. Before feeding and milking, wash the body of cows with cold water. For individual cows that are afraid of heat, rinse the cow's head and chest with cold water. This will not only reduce the body temperature of the cow, but also keep the body clean. Simultaneously, the feces should be promptly removed. The cowshed is sterilized once a week with 5% of susu or 2% sodium hydroxide solution, and some straw ash or lime powder can also be used to disinfect, deodorize, and remove moisture. To reduce the incidence of the disease. 8. Preventing mosquitoes and mosquitoes from interfering with summer. Mosquitoes and other pests are prone to breeding, biting cows, and disturbing the rest of dairy cows. They are extremely detrimental to the milk production of dairy cows and can also spread diseases. The cowshed can be sprayed with insecticide-flies liquid to eliminate mosquitoes and flies and provide a comfortable living environment for cattle.
