Summer dairy cows pay attention to what?

The suitable temperature for dairy cows is 10°C~20°C. In summer, the temperature is high and humid, which may cause the appetite of dairy cows to decrease, the spirit is not working, and the milk yield decreases. Strengthening feeding and management can reduce the degree of heat stress and maintain the stable and high yield of dairy cows in the summer.
1. Use cooling facilities to increase the air circulation in the barn. For the semi-enclosed barn, doors and windows and wind screens should be opened to increase ventilation. For open cowsheds, ventilation facilities or electric fans can be installed if conditions permit, which can reduce the temperature in the house by 2°C to 3°C and accelerate the heat dissipation of the cattle body.
Install mist spray facilities. Spray the cow's head and bosom with cold water mist to reduce the temperature of the bovine body, but it should be noted that the water spray should generally be carried out in the mid-day when it is hot. The time should not be too long and the frequency should not be too frequent, otherwise it will lead to humidity inside the house. Large, causing cows to heat difficult. Normally, the cowshed should be kept dry and free of water. The relative humidity should be kept below 80%.
2. Improve the feeding method Adjust the feeding time, feeding early or late (before 7 o'clock in the morning or after 9 o'clock in the evening).
Appropriately increase feeding times and increase night feeding. It is recommended that the amount of feed should account for more than 60% of the ration in the evening in the summer. This can compensate for the lack of feed intake due to high temperature anorexia.
3. Improve dietary nutrient concentration and adjust the composition of dietary feed ingredients. The first is to adjust the ratio of fine to coarse in the diet, that is, to increase the proportion of concentrates and reduce the amount of coarse feed. Note that the maximum proportion of concentrate should not exceed 60%. The second is to adjust the feed ingredients for the diet, reduce the amount of general feed, increase the quality of feed such as whole-grain cottonseed, soybean, high-quality herbage, whole plant silage, etc. The pre-lactation and high-yield dairy cows should also be added with fatty acid calcium, amino acids, etc. Rumen feed varieties.
Rumen buffer is used. Due to the increase in the proportion of concentrates in the summer diet, the diet should be supplemented with 0.75% to 1.5% sodium bicarbonate (baking soda) or 0.35% to 0.40% magnesium oxide, which is beneficial to the rumen for nutrients. Digestion and absorption.
Add heat stress relief substances. An additional supply of potassium, sodium, and magnesium is needed in the diet. For each cow diet, 30 to 50 grams of potassium carbonate, 60 to 100 grams of magnesium sulfate, and 120 to 160 grams of salt can be added.
Since heat stress increases the consumption of vitamin A in dairy cows, the amount of vitamin A in the diet should be doubled in summer.
4. Ensure clean drinking water In the summer, the amount of water consumed by lactating cows can be supplied 3 to 5 times the amount of milk produced. Always clean the sink, regularly sterilize, replace drinking water, keep it fresh and cool, and let the cows drink freely.
5. Strengthen hygiene management and disinfection More mosquitoes and flies in the summer, spray the bovine body and surrounding environment regularly with aerosol insecticide to eliminate mosquitoes and flies. To remove excrement in time, keep the barn and playground clean and dry. Disinfect once a week with 5% of suzhou children or 2% caustic soda solution, you can also often disinfect the cowshed with lime powder to deodorize and dehumidify and reduce the occurrence of summer diseases.
