Description

The invention relates to animal husbandry, namely to feeding highly productive cows in the most crucial period, namely during the first phase of lactation.

It is known, taken as an analogue of a premix for cows (options) according to the patent of the Russian Federation No. 2145479 dated 11.24.97, The specified premix contains succinic and folic acids, selenium, zinc, copper, cobalt, iodine, manganese, magnesium and vitamins D.

The disadvantage of the analogue is that it does not take into account the availability and assimilation of dietary energy, does not have a noticeable effect on the immune status of cows and does not improve the biochemical parameters of the blood.

Known, taken as a prototype ration, for high-yielding cows, calculated according to the norms given in the Reference manual "Norms and rations of feeding farm animals" edited by A.P. Kalashnikov and others - Moscow. 2003, pp. 42-53. The specified diet includes the following ingredients:

and contains:

The disadvantage of the prototype is that although this ration provides the needs of cows in gross energy, it does not take into account the availability and assimilation of the ration energy. Diet fats are known to oxidize and form peroxide compounds that negatively affect energy availability. In addition, this diet does not have a noticeable effect on the immune status of cows and does not improve the biochemical parameters of the blood.

The aim of the invention is to eliminate this disadvantage.

This goal is achieved by the fact that the energy feed additive to the daily ration of highly productive cows with an average live weight of 600-620 kg during the first phase of lactation, which lasts up to 100 days of lactation, and with a milk yield of 30-35 kg, according to the invention, characterized in that it contains 250 mg of dihydroquercetin, 500 mg of arabinogalactan and 0.5 kg of “protected” fat, which is introduced into the diet, which includes the following initial ingredients: alfalfa hay - 3.33 kg, hay - 14.37 kg, corn silage - 14.86 kg , corn - 1.29 kg, wheat - 0.34 kg, barley - 0.34 kg, sunflower meal - 1.32 kg, soybean meal - 1.76 kg, corn gluten 0.67 kg, hydrolytic yeast 0.44 kg, baking soda 0.20 kg, premix - 0.05 kg.

The inventive feed additive, which includes dihydroquercetin, destroys peroxide compounds of diet fats and increases the efficiency of their use by cows by 17-21%.

Arabinogalactan, which is a part of the claimed feed additive, increases the immune status of cows and improves the biochemical parameters of the blood of cows.

Comparative analysis of the proposed solution with known energy feed additives to diets for highly productive cows allows us to conclude that it meets the criterion "NOVELTY", since as a result of the patent information search, the proposed set of essential features of the invention was not found.

Comparison of the claimed technical solution with the known ones made it possible to identify signs that are not obvious to an average specialist in connection with the technical result achieved by the entire set of essential signs. This allows us to conclude that the proposed technical solution is in accordance with the criterion of "INVENTIVE LEVEL".

The claimed technical solution meets the criterion "INDUSTRIAL APPLICABILITY", since it can be used for feeding highly productive cows during the first phase of lactation.

The essence of the invention is illustrated by an example of a specific implementation.

In 2018, ZAO Kolos of the Tikhoretsk District of the Krasnodar Territory conducted a scientific and economic experiment on four groups of cows (8 heads in each group) of the black-and-white breed of the second calving with an average daily productivity of 16-18 kg. The groups were formed according to the principle of analogous pairs with an average live weight of 600-620 kg. The experiment was carried out according to the scheme shown in table 1.

The animals of the experimental group additionally included dihydroquercetin in the amount of 250 mg per head per day and 500 mg of arabinogalactan in the diet. For thorough mixing with the compound feed, dihydroquercetin and arabinogalactan were introduced through the premix.

In the control and experimental groups, the level of energy deficit reached 10-15% of the physiological norms of need. And for other nutrients, the level reached 100% of the norm.

The diet of the third group was balanced in all nutrients, including energy. At the same time, 100% of the energy requirement was provided by the introduction of "protected" fat (table 2).

Cows of the fourth group received the ration of the third group with the additional inclusion of dihydroquercetin in the amount of 250 mg and arabinogalactan - 500 mg, 0.5 kg of "protected" fat per head per day. The ration of feeding throughout the experiment corresponded to the generally accepted norms for high-yielding cows.

It was found in the experiment that cows in all groups showed high milk productivity. Average daily milk yield fluctuated in the range of 28.2-36.7 kg.

The relatively low productivity of cows in the control group is probably associated with an energy deficit (10% of the physiological requirements).

As a result of the experiment, it was found that the inclusion of dihydroquercetin and arabinogalactan in the diet of highly productive cows contributes to an increase in the energy use of the diet by 8.0-18.2%.

In addition, there was an improvement in the biochemical parameters of blood in the experimental groups: total protein by 9.6%, globulins by 12.4%, glucose by 23.0% and a decrease in ketone bodies in milk by 34.2%.

The data obtained allow us to note the positive effect of dihydroquercetin and arabinogalactan in the composition of mixed feed on the physiological state of cows.

Thus, the inclusion of dihydroquercetin, arabinogalactan and “protected” fat in the diets of high-yielding cows contributes to an increase in the energy use of the rations by 8.0-18.2%.
