The high temperatures in summer bring serious threats to the production of dairy cows. Therefore, it is necessary to grasp the feeding and management of dairy cows during the high temperature season.
I. Feeding of dairy cows in high-temperature and low-rain season
1. Because of the drought, the pasture is not growing well and the nutrition that cows normally take on forage grass is not satisfied. Therefore, it is necessary to break the conventional feeding amount when feeding, and appropriately increase the amount of concentrate feed, the growth rate is about 10% to meet the normal growth and production needs of dairy cows;
2. Appropriately reduce the amount of energy feed (decrease by 8%) and increase the amount of protein feed (increase by 5%). Due to the poor palatability of hot dairy cows and the large amount of leftovers, it is advisable to change part of the concentrates to feed once at lower temperatures at night.
3. Appropriately add sodium bicarbonate (Sudoda) 50-80 g/day in the dairy cow diet to adjust the pH in the rumen.
4, pay attention to calcium, phosphorus supplements. Normal amount: 50 to 100 grams daily. Feeding concentrated feed can be appropriately reduced.
5. In the summer, the cow's skin evaporates more and the loss of sodium is greater. When feeding, attention should be paid to the amount of salt, which is normally about 100 g/day. 6. In the summer, the preparation of dairy concentrates should be carried out half an hour before feeding to prevent rancidity and reduced palatability.
7, take free drinking water, drinking water should be clean.
8. After the dairy cows in pastoral areas return to animal husbandry, they should pay attention to the supplementation of roughage, and add hay, corn stalks, and silage that have no mildew. In order to increase the palatability of dairy cows, it is best to spray salt water on the green hay. The corn stalks are best crushed and chopped.
9. When high-yield bovine concentrates are supplemented, the most difficult part is the addition of energy feeds. If it is too high, it may cause diarrhea. If the low-calorie cows are gradually thin, it is best to add 50 to 100 grams of brown sugar daily, especially in summer. .
Second, the management of dairy cows during the heat and rainy season
1. Grazing cows in pastoral areas. Morning: Early Grazing and Early Grazing; In the afternoon: late, pastoral, and late return. No matter whether it is large or small cattle must be herded. In view of the drought, pastures are growing poorly. In order to meet the normal feed intake of dairy cows, it is recommended that small groups be grazing.
2, scrub cattle body. The cattle body should be brushed frequently. When washing the cattle body, the outdoor temperature should be above 20°C, the water temperature should be around 15°C, and the washing sequence should be from front to back and from top to bottom.
3. Pergola should be built in the stadium to require high ground, good ventilation, and direct sunlight to reduce the burden on the cow's high temperature.
4, pay attention to eliminate mosquitoes and flies, to ensure the normal rest of the cows, killing mosquitoes and drugs is best to use high-efficiency, low-toxicity drugs. Do not use raw smoke.
5. When the temperature is high, the cattle bed is washed with cold water, which can reduce the temperature and increase the humidity of the barn.
6. It is best for cows in normal weather to be outside. In case of abnormal weather, the cows must enter. There is no scientific justification for the saying that "sunshine drying horses".
7, to do a good job of cow deworming: cows are best to repellent three times a year, the current best anthelmintic drug is insect buprofen with albendazole.
8, observe the cow's spirit, appetite, digestion, lactation, etc., found that the condition early diagnosis and treatment.
