How much milk does a cow give a day, and what does the milk yield depend on?
The man domesticated a cow about 12 thousand years ago. The ancestor of our burrs is a wild tour, a strong, ungulate animal, with black, shaggy hair and a white stripe along the back. Their area was Europe, Asia, some regions of Africa. Males of tours were used by people as draft power during construction and digging, and their females gave milk. However, he only had enough to feed his own cubs. Discovering its nutritional value and taste, people have learned to give out tourists.
With the course of time, their appearance began to change. Individuals grew larger, due to the fact that they began to feed better and stopped using for hard work. The physiological characteristics of the cow udders have also changed. From generation to generation milking of cows led to the fact that their udders "tuned" to the continuous production of milk. In ancient times, hardly anyone thought about how much milk a cow gives a day.
The man has worked hard to breed different breeds of this remarkable animal. There are breeds of cows adapted to life in different climatic conditions: in the mountains, in the severe northern climate and in the steppe. They are furry and smooth, black and white, high and not very much. Whatever the cow, its main purpose is to give milk.
When cows have milk
As in all mammals, the prolactin hormone contributes to the production of milk, respectively, the mother's milk appears after the birth of the baby. Milk is formed in the body of the cow so that the calf can feed. Each emptying of the mammary gland causes its subsequent filling. Once the extrusion ceases, the appearance of milk stops. The average milk yield per cow per day in this case can be sharply reduced.
In nature, this is exactly what happens. The calf grows, loses the need for milk, and it eventually disappears. However, man has learned to artificially support the "production" of milk by regular milking.
How much milk gives a cow per day, largely depends on proper care for it. It's not just daily grazing and milking. In summer and winter, the cow needs to be cleaned, washed, and hoofed. In the summer it can be completely bathed. The stall must also be kept clean. Not every cow will lie on a dirty mat. Most likely, in this case, the burenka will stay up all night on its feet, and in the morning give milk less than usual.
For convenience in the floor of the stall you can break through a groove, where you can throw down manure. From there it is easier to collect and take out of the cowshed. Such a groove should be located in the side opposite to the feeder. The cattle should be lighted and not too large to keep the heat there in the winter. Before leaving the wet nurse to the winter stall, the feeder, the leash, the floor in the stable and other "cow" utensils, it is desirable to disinfect. Do not allow drafts.
Proper feeding of dairy cow
The popular saying goes: "It is good to feed cattle - it's expensive, it's bad to feed - ruin". Feeding cattle is the most expensive "moment" in its content. In a day, depending on the physiological characteristics, the burenka can eat up to 70 kilograms of various foods. If the cow is undernourished, the milk yield will drop by half, the animal will lose a lot of weight. The quality and volume of food directly affect how much milk a cow produces per day.
In the pasture period, the cow basically eats grass. But her diet should be supplemented with other types of feed to improve the quality and quantity of milk. The winter menu of the cow, designed for one day, should consist of the following products:
- Hay or spring straw is 7-8 kg.
- Sugar beet, Jerusalem artichoke or potatoes - 10-15 kg.
- Feed carrot - 2 kg.
- Wheat bran - 5-6 kg.
- Cake, meal - 1-2 kg.
- Food waste, bread - up to 8 kg.
- Salt - 100 g.
- Oats, corn - up to 7 kg.
It's important for the owners to remember that the cow is a kind and intelligent animal. She feels how she is treated and feels kindness. Of course, nutrition plays an important role in the productivity of the animal, but a good attitude has a significant effect on how much milk a cow produces per day.
Milk yield in cows, or how much a cow gives milk
A young ladybird a day gives about 9-10 liters of milk. With age, "milk" increases. Its peak reaches to the fifth-sixth calving and can reach 12-14 liters per day. However, there are borenki-record holders, the daily yield of which reaches 20 liters. Based on this figure, you can calculate how many liters of milk a cow can give per year. On average, this figure ranges from 4 to 5 thousand liters.
In summer, when there is a lot of fresh grass, the productivity of milk increases, in winter it, accordingly, becomes less.
Dairy breeds of cows
Assessing the "milk" of a cow, it is necessary to take into account its age, the quality of nutrition, the breed, the productivity of its mother or other relatives. The most dairy breeds in our country are:
- red steppe;
- black and motley;
- red and motley.
