First, increase the suitable temperature of the cows in the Sherwin Cow is 8°C-16°C. In this range, the cow's metabolic rate and heat production are at the lowest level. The performance is: low feed consumption and low incidence. If the temperature of the barn is below 0°C, the cattle will emit a lot of energy to maintain body temperature. Therefore, the doors and windows and wall joints on the west and the north side of the cowshed should be tightly closed to prevent thieves from invading; the doors and windows on the sunny side should be hung. In addition, cows should not spend more than 6 hours during the day in the stadium. It is best to have 3 hours of activity in the morning and afternoon.
Second, adjust the barn humidity After the cows all enter the pens, pay attention to keep the ventilation in the barn, the humidity can not be too large. The relative humidity should not exceed 55%. If the humidity is too high, there will be a strong external stimulus to the cow, which will affect its milk production. In severe cases, it will also infect some fungal diseases. At the same time, it is necessary to remove urine in time and keep the house clean and dry.
Third, feed should be diversified should adjust the feed ratio in a timely manner, and strive to diversify. In the supply of concentrate feed, the protein feed will remain unchanged, and the supply of corn will increase by 20% to 50%. In the aspect of roughage, it is best to feed silage, microbiological feed, or brewer's grains instead of summer and autumn. Green Juicy Feed:
Fourth, drinking water must be warmed unheated tap water and well water, easy to freeze in winter, cows often lead to indigestion after drinking, thereby inducing digestive tract diseases. According to reports, drinking milk at 8.5°C in winter cows is about 8% higher than drinking water at 1.5°C. The suitable temperature for dairy cows to drink in winter is: 12°C-14°C for cows, 15°C-16°C for dairy cows, and 35°C-38°C for calves.
5. The appropriate amount of supplemental calcium, phosphorus and salt can be added to the cow's feed with appropriate amounts of calcium and phosphorus. Generally, it can feed 5-15g per day. Urea is an effective measure of protein supplementation and can be fed on a diet. Generally, calves of more than 6 months of age are fed 30-60g daily, shelf cattle are fed 70-90g daily, and adult cows are fed about 150g on a daily basis. However, urea is poor in palatability, and it can be mixed with 1% of the concentrate and fed with grass. It is not advisable to drink water within half an hour after feeding. In addition, depending on the size of the cow's body weight and the amount of milk produced, 50-100g of salt should be provided daily.
6. Brushing the body of the cow to brush the body of the cow can not only keep the cow clean, but also promote the skin's blood circulation and metabolism, help regulate body temperature and enhance disease resistance. Therefore, brush twice a day, morning and evening, 3-6 minutes each time, you must thoroughly brush all parts of the body. In addition, it is necessary to regularly sterilize cowsheds and sports grounds and vaccinate them according to the epidemic prevention procedures. Early treatment of the disease is found to ensure the health of dairy cows and ensure the prolific milk production.
VII. Grasping dairy cows is usually “summer with spring and winter with autumnâ€. Winter mating and pregnancy can avoid hot summer calving and help dairy cows achieve high yields. Therefore, dairy farmers should seize the golden opportunity in the winter to do a good job of breeding cows, increase the rate of quaternization, and lay a good foundation for the successful birth and healthy growth of new calves.
