How many catties of beans does the cow feed a day?

A Niu, with a daily milk production of 20kg, needs to eat 5kg of hay or crop straw, 20kg of green fodder or silage, 9kg of mixed concentrate, tubers or dregs 10kg, and the total dry matter 18kg.

How do cows produce more and better milk?

If cows want to produce more milk, they must first have excellent cow breeds, high-quality feed and scientific management. From the nutritional point of view of dairy cows, dairy farming should first pay attention to the ratio of concentrate to roughage in the diet structure. Coarse feed mainly meets the maintenance needs of dairy cows, and mixed concentrate and juicy feed mainly meet the milk production needs of dairy cows. If the quality of roughage is good, mixed concentrate can be put in the ratio of milk to feed of 2.5 ∶ 1, and if the quality of roughage is poor, mixed concentrate can be put in the ratio of milk to feed of 2.2 ∶ 1.

In order to ensure the stable and high yield of dairy cows, not only the ratio of milk to feed, but also the ratio of concentrate to coarse dry matter (45 ∶ 55 ~ 55 ∶ 45), the ratio of dry matter of Tibetan grass feed (50∶50) and the ratio of calcium to phosphorus (1.5 ∶ 1 ~ 2 ∶ 1) should be considered when formulating diets.

Judging from the current situation in China, the poor quality of roughage is mainly dairy farming, especially rural retail farming. It is a good way to improve the quality of roughage and popularize alfalfa feeding. Since alfalfa was introduced to Shanghai, Beijing and other places, the effect is obvious.

What are the suitable living environment and conditions for dairy cows?

Cows are generally cold-resistant and heat-resistant, and are particularly sensitive to the high temperature in summer and the cold wind in winter. The suitable environmental temperature for dairy cows is 5℃ ~ 2 1℃, the most suitable environmental temperature is 10℃ ~ 15℃, the tolerance range is-15℃ ~ 26℃, and the feed intake of dairy cows is lower than-15℃, especially higher than 20℃. Compared with 15℃, the milk yield decreased by 25% above 26℃. Above 35℃, the milk yield decreased by 50%.

The relative humidity of air should be 50% ~ 70%. When the relative humidity exceeds 75% in summer, the milk yield decreases obviously. When the wind reaches level 5 or above in winter, the milk yield decreases obviously.

Cows are quiet and don't like noisy environment. Strong noise will cause stress reaction in dairy cows, reduce milk production, or produce alcohol-positive milk with low acidity. Cows should be given enough rest time and quiet environment after eating to ensure normal rumination. Normal rumination is one of the signs of cow health. Cows like a clean and dry environment. Therefore, the floor of the barn should be cleaned and washed every time after going out of the trough, and the feces on the playground should be removed in time to keep it flat, dry and clean to prevent water accumulation.
