Description

The invention relates to the field of agriculture and can be used in animal husbandry and is intended to increase milk productivity by enriching feed rations with protein components, vitamins and mineral elements.

Milk productivity is inextricably linked with the intensity of all types of metabolic processes. Only with optimal provision of plastic and biologically active compounds of the animal organism is the most complete manifestation of the genetic potential of productivity possible. Highly productive lactating cows in stressful conditions are not able to fully cover milk production due to nutrients in the feed, due to which muscle tissue proteins and minerals of their own body are partially consumed [1, 2].

Taking into account the above, there is a need to develop an optimal method for the combined use of extruded white lupine with pine needles, select effective doses for feeding them, and identify a correlation between the use of the proposed additive and the level of milk productivity.

A protein-mineral feed additive and a method for increasing milk productivity of cows are known [3].

A known method consists of introducing sapropel (0.84 kg), probiotic "Sakhabactisubtil" (10 ml), elements and microelements - iron (4 g), cobalt (50 mg), zinc (2 g), iodine (30 mg), copper (2.5 g), manganese (30 mg), vitamins A (100,000 IU), D3 (13,350 IU), E (100 mg), B1 (50 mg), amino acids - lysine (5 g) and methionine (2 g) into the daily diet of dairy cows for 3 months, contributing to the normalization of the physiological state of the experimental cows, an increase in milk productivity and fat content in milk by 0.22 l and 0.14%, respectively [3].

The method we chose as a prototype is labor-intensive, expensive, and not effective enough due to the fact that only two amino acids are used to normalize protein metabolism (protein biosynthesis requires many more, 10 of which are essential), as well as the expensive probiotic "Sakhabactisubtil".

The technical problem that the invention is aimed at solving is increasing milk productivity and milk quality of dairy cows.

The objective of the invention is to create a new, effective, easy-to-prepare protein-vitamin natural feed additive and to develop a method for increasing milk productivity during the winter stall period under stressful conditions of an industrial complex.

The technical result is achieved by morning feeding, in addition to the main diet, with a protein-vitamin supplement of extruded white lupine and crushed pine needles, in a ratio of 1000 g of white lupine and 200 g of pine needles, for 30 days in the amount of 2000 g of the above-mentioned supplement per head.

Extruded white lupine grain contains at least 38% protein, including 91% soluble, 4.5% fiber, 18% fat, the level of exchange energy is 340-360 kcal/100 g, which allows it to be used as a protein supplement in animal feed rations. It is known that at controlled temperature and humidity in the process of white lupine extrusion, thermal hydrolysis of lupine biopolymers occurs, which have protein and energy nutritional value, while a hydrophilic colloid is formed, protected by a hydrate shell. In this regard, the protein substances of lupine are not destroyed to amino acids, and amino acids are digested in the intestinal lobes. The nutritional composition of extruded white lupine is presented in Table 1 [4-6].

The content of vitamins in extruded white lupine and pine needles is presented in Table 2. [7-9].

The protein-vitamin feed supplement has the following ratio of components:

The method of increasing milk productivity of cows is characterized by the fact that in addition to the main diet, cows are fed a protein-vitamin feed additive made of extruded white lupine (ECL) and pine needles (XP) daily at 2000 g of the mixture. The research scheme is presented in Table 4.

The milk productivity indicators we obtained are presented in Table 5.

An analysis of the obtained results of the proposed method for increasing milk productivity relative to the beginning of the experiment showed that in the group that received a composition of extruded white lupine and crushed pine needles (in a ratio of 1000 g white lupine and 200 g pine needles for 30 days in an amount of 2000 g per head):

Average daily milk yield increased by 6.0 kg (41.4%);

Milk yield increased by 180.0 kg in 30 days;

Milk protein content increased by 7.5%;

Milk fat content increased by 98%;

SOMO increased by 30%;

The density increased by 3.2 kg/ ^m3 (1.9%).

Relative to the control group, the data changed as follows:

Average daily milk yield increased by 6.5 kg (46.4%);

Milk yield in 30 days increased by 195.0 kg;

Milk protein content increased by 17%;

Milk fat content increased by 62%;

SOMO increased by 9.1%;

The density increased by 0.67 kg/ ^m3 (1.9%).

The use of an additive made from extruded white lupine and pine needles allows us to recommend the proposed additive for use in feeding cows in stressful conditions of an industrial complex during the winter stall period to increase milk productivity due to the source of protein and vitamins from extruded white lupine and an additional amount of vitamins from pine needles.
