How to do a good job in nutrition regulation of dairy cows in high temperature season

<

Feeding green and juicy feed Green and juicy feed is rich in carbohydrates and water. It not only has good palatability, but also thirst-quenching, which is very beneficial to cool the sunstroke and relieve the heat stress of cows. Under the premise of ensuring adequate intake of dry matter, appropriate amounts of high-quality grass, carrots, wax gourds, watermelons, sweet potatoes, potatoes, etc., are beneficial for increasing the milk production of dairy cows and increasing milk fat percentage. Concentrated feed can be fed with some good feeds such as bran and soybean meal.

Feeding the congee material will change part of the concentrate feed to congee material. 1.5 kg of refined feed, 1.25-2.5 kg of carrots, 58 kg of water, and porridge-like, cool and pour on silage, can increase the amount of urine in the milk and take away more calories.

Feeding saltwater bran soup to cows to feed salt bran soup can increase appetite, ensure drinking water, regulate metabolism, and effectively control milk production. Every time a cow feeds 50 kilograms of water, 50 grams of salt and 1–1.5 kilograms of bran are fed 3 times a day.

Feeding mung bean soup mung bean soup has the effect of clearing heat, detoxifying, and cooling the body. Conditional farms (households) should give cows green bean soup in the summer. Use fresh green beans 1-1.5 kilograms, add 4-5 kilograms of water, boil for 1-2 hours, add 40 kilograms of clean drinking water, and give cows a Beverage Service once a day.

Supplemental sodium bicarbonate supplemented with sodium bicarbonate helps to maintain acid-base balance in dairy cows, and also helps digestion, which can increase the intake of dairy cows. The amount of sodium bicarbonate is generally 3.84% of concentrate, or 340 grams per day per cow. It works better with citric acid. When using sodium bicarbonate, the amount of salt should be properly reduced.

When heat stress is applied to the supplemental potassium chloride cows, the potassium output is significantly increased, resulting in a decrease in the amount of potassium in the blood, which must be supplemented with potassium. Potassium chloride can generally be added to cows drinking water or to food rations, in an amount of 60-80 grams per day per cow.

Vitamin C cows produce heat stress, vitamin C synthesis ability declines, but the demand has increased, so the hot summer should pay attention to vitamin supplements to cows in the heat stress process, vitamin C can also inhibit cow body temperature rise, promote appetite, Improve disease resistance. In the summer, 0.04%-0.06% vitamin C can be added to the cow's feed.

Vitamin E supplementation Vitamin E prevents the oxidation and destruction of fat in dairy cows, prevents the production of oxides in the body, prevents the oxidation of other vitamins, and promotes the absorption of vitamin A and vitamin D in the intestine. In summer, a normal amount of 3-5 times of vitamin E can be added to feed to reduce the risk of heat stress in dairy cows.
