High-yielding cows need to feed 80 kg to 100 kg of feed per day (about 20 kg to 25 kg of dry matter) to meet their physiological needs. High-yield dairy cows generally have a daily milk production of more than 30 kg, and a milk production period of more than 6000 kg. Because high-yielding cows want to squeeze out a lot of milk, they need a lot of nutrients.
Due to the digestion and absorption of nutrients in these feeds, not only the digestive organs work hard, but also the metabolic function of the whole organism is also enhanced. Therefore, cows must be physically strong to adapt to these physiological functions.
The diet of high-yield dairy cows requires a complete distribution of nutrients, rich in feed, good quality, and easy to digest and absorb. The diet is generally based on high quality hay, silage, roots and green succulent feed, with appropriate concentrate added. Because the green and juicy feed is not only good in palatability, but also promotes the full secretion of digestive juice, thereby improving the utilization efficiency of other feeds. Practice has proved that high-yield and stable production cannot be based on the addition of concentrates. Only by adding the concentrates on the basis of increasing the coarse materials can the full effect of the concentrate be fully utilized.
The diet of high-yielding dairy cows must not only ensure the quantity, but also ensure the quality. The feed should include various amino acids such as lysine, tryptophan and arginine which are necessary for the formation of milk. In other words, the higher the full price of protein in the diet of high-yielding dairy cows, the better the effect on increasing milk production. Moreover, the more appropriate the proportion of coarse materials, succulent feed and concentrate in the diet, the better the quality, and the more appropriate the proportion of mineral supplements, the higher the yield and the higher the yield.
High-yielding dairy cows should increase the number of feeds they consume each day, so they should increase the number of feedings, usually more than 4 times a day. Drinking water should have automatic drinking fountains. If there is no automatic drinking fountain, the number of drinking water should be more than 5 times a day.
In the daily management work, you must do it every day in the morning and afternoon. Let the cows do the proper outdoor exercise every day.
