Common ways to increase the milk production of dairy cows: First, select good breeds and choose hybrid cows with large size, fast growth, strong adaptability, and high production performance. Secondly, the supply of nutrients that are rich in protein and energy, such as nutrient balance, adequate green materials, supplemental feed supplements with appropriate amounts of additives, reasonable lengthening of the light hours, increased exercise, scientific milking, and careful management can also increase milk production. In addition to these basic measures, the following methods can also be used to increase milk production. First, feed fermented corn stalks. Feeding corn stalks to dairy cows after fermentation can significantly increase palatability and facilitate digestion and absorption, which can increase milk production by 10%. Second, feed honey pollen. Adding honey pollen to the cow's feed can increase milk production by more than 10%. Third, the summer and autumn night animal husbandry. During the hot summer and autumn seasons, changing to grazing in the night can increase the average daily milk production per cow by more than 500 grams. Fourth, deworming health care. After cows are born, thiabendazole is taken at 70 mg per kilogram of cow's body weight to drive out the parasites in the cows, which generally increases milk production by about 10%. Fifth, feed urea. Dissolve the urea in the water, then mix the feed with urea solution. Note that each cow should not exceed 80 grams per day, which can increase milk production by 15%. Six, feeding potatoes. The test confirmed that in the summer hot season, increasing the amount of potatoes to the lactating cows will help increase milk production. As the potato contains rich nutrition and strong palatability, it can enhance the appetite of dairy cows during the high temperature season and increase the feed intake of dairy cows, so as to ensure the nutritional requirements for milk production and weight gain of lactating dairy cows and play a role in cooling and cooling. And the effect of promoting milk, at the same time as the potato contains a large amount of starch, in the bovine body by the role of amylase, can be converted into a variety of nutrients for cattle weight gain and lactation. Seven, smell the smell of cattle. The researchers found that spraying cows with dairy cows with fragrant substances (such as fennel oil) can help cows get along better and increase their milk production. In the past, there was a common phenomenon of mutual biting, crowding and bumping among dairy cows, which caused the cows to be tense and disturbed, and the yield was greatly affected. After spraying with fennel oil, the cow's aggressiveness was greatly reduced, and the mood was relaxed, and the peace of mind was relaxed. Milk volume increased significantly. Eight, feed congee material. The palatability of the porridge material is good, which can increase the feed intake of the dairy cow, and it is beneficial to the digestion and absorption of the dairy cow, thereby greatly improving the effective utilization rate of the feed. The specific method is: first dilute the concentrate with water, and then pour boiling water, stirring 5-10 minutes to mix the fine material into a porridge. The feed water ratio is 1:10-15 in winter and 1:20-30 in summer. Feeding dairy cows using porridge methods generally increases milk production by more than 10%.
