Annotation.
When feeding cattle, including cows, the bulk of the ration consists of bulky feeds. High-quality hay, haylage, wheat, and barley straw, which contain large amounts of fiber, are among the bulk foods used to feed cows. For example, high-quality hay harvested at the beginning of the flowering phase and prepared for consumption has a very close nutritional value to natural hay. Hay is usually rich in high-nutrient proteins, easily digestible carbohydrates, vitamins and minerals, and can be added to large rations.
Silage is the most convenient and cheapest form of feed for dairy cows when they are fed in a stationary condition. The essence of silage is the reduction of organic acids and the acidity (pH) of the silage mass -3.0-4.2 as a result of digestion of carbohydrates in silage. The nutritional value of silage and its aromatic properties depend mainly on the type of silage and silage technology.
Nutrients in the diet of dairy cows such as beets, carrots, potatoes, Jerusalem artichokes are a source of easily digestible carbohydrates, are very well consumed by animals, along with a positive effect on digestive processes improves milk secretion.
In addition, the group of concentrated foods includes grains of cereals and legumes, bran, sorghum, shrot and others. Concentrated foods store large amounts of protein, easily digestible carbohydrates, fats, minerals and vitamins. These nutrients are consumed with great appetite by dairy cows, however, as the market price of these nutrients is much higher, they are usually balanced with different nutrient components in order to increase the nutritional content and enrich them with biologically active substances. is added to the ration for the purpose. It should be noted that the addition of concentrates to mixed feeds is much more effective.
In order to use nutrients efficiently, it is best to prepare them before eating. To do this, a complete dietary mixture is prepared in crushed form, which meets the needs of cows for nutrients, minerals and biologically active substances. This mixture is easy to prepare and distribute by mechanization and is called full ration, monorail or mono-food.
The nutrients of the above-named groups, if their quality is high enough, are the nutritional value necessary to ensure that the health, reproductive functions and productivity of the animals are maintained to a certain extent, biologically. allows you to balance the rations of dairy cows on the active ingredients.
Providing cows with protein and minerals stored in these feeds, feeding them a multi-component diet, the consistent distribution of various physiologically important nutrients, leads to an increase in their physiological processes and productivity.
