Description

Analysis of the dynamics of milk production of cows during the year shows extremely unstable results. As it turned out, a decrease in milk productivity occurs for two main reasons:

1) hypoglycemia in cows with high milk yields,

2) the unsatisfactory quality of the silo, especially in the spring.

The first reason is specific for highly dairy cows and is greatly exacerbated by various kinds of stress. An increase in blood glucose can be achieved in various ways, including using the “Method for optimizing the composition of the diet for cattle and pigs by introducing regulatory substances” proposed by the authors (Priority on application No. 2010141195). In accordance with this method, preservation of milk productivity under stress is achieved by introducing polysaccharides - oligofructose and inulin, sorbitol in combination with easily digestible carbohydrates (fast) - glucose, fructose, maltose and phospholipids into the diet. Nevertheless, studies are being conducted in the world aimed at constantly improving the way to increase blood glucose. The authors found that the essential oils of anise, cinnamon and cloves, taken in certain proportions, have the ability to enhance milk productivity, including by relieving hypoglycemia.

The second reason is the unsatisfactory quality of the silo. Silage is the main source of digestible fiber and protein. By spring, the most important nutrient for the growth of cicatricial microflora - amino acids - is leaving the silo mass. These free amino acids are formed as a result of hydrolysis of grass proteins (mainly legumes) by lactic acid microorganisms. However, during storage of the silo, free amino acids and peptides are utilized by extraneous microflora, and the silo no longer has stimulating properties with respect to scar microflora. So there is a "feed stress", i.e. with a change in silage, milk production is significantly reduced.

The authors found that yeast hydrolysates (acidic, enzymatic), as well as soy hydrolysates and milk protein hydrolysates obtained by hydrolysis of lactic acid bacteria Lactobacillus acidofillum, have the ability to restore scarring-stimulating function of silage and prevent the onset of “feed stress”. The proposed method of stabilizing milk productivity under conditions of “feed stress” involves the use of a combination of polysaccharides — oligofructose, inulin, sorbitol and easily digestible carbohydrates — fructose, glucose, maltose, phospholipids, essential oils — cinnamon, cloves and anise with soy and yeast hydrolysates in one product. Thus, the proposed method involves the use of a product with a composition of the following composition:

- oligofructose - 100-200 g

- inulin or arabinogalactan - 200-300 g

- sorbitol - 200-300 g

- easily digestible carbohydrates - glucose, fructose, maltose - 100-200 g

- phospholipids - 150-250 g

- anise oil - 5-10 g, cinnamon oil - 2.5-5 g, clove oil - 2.5-5.0 g, yeast hydrolyzate - 100-200 g, soy hydrolyzate - 100-200 g.

The found ratio of components in the proposed composition of substances allows us to solve an extremely important problem - the elimination of "feed stress" in relation to one of the most significant sources of carbon and protein - silage. As tests have shown, a new product with the above composition allows to obtain stable milk yield while reducing the quality of the silo in the conditions of its long-term storage. The following are examples of the method in cattle farms.

Example 1

Farm "Kalozhitsy" of the Leningrad region, April 2010. The cows in the crib were given 10 kg of feed (feed / forage) and 20 kg of silage. In the control group (50 goals), a decrease in milk productivity was observed compared with the period from February to March. It was found that the observed decline in milk productivity is associated with a decrease in the content of digestible protein. The product obtained by the proposed method of the following composition was introduced into the diet of the experimental group for 3 months:

- oligofructose - 100 g

- inulin - 200 g

- sorbitol - 200 g

- easily digestible carbohydrates - glucose, fructose, maltose - 100 g

- phospholipids - 150 g

- anise oil - 5 g / kg, cinnamon oil - 2.5 g / kg, clove oil - 2.5 g / kg, yeast hydrolyzate - 100 g, soy hydrolyzate - 100 g. Dosage - 100 g / head. day. The test results are shown in table 1.

Table 1 The test results of the proposed composition for stabilizing milk production Milking in the control group Milking in the control group Milking in the experimental group Milking in the experimental group March-February 2010 April 2010 March-February 2010 April 2010 l / goal l / goal l / goal l / goal thirty 27 32 33 Blood Glucose (Mmol / L) 2,5 1,2 3,1 4.3

From the data of Table 1 it can be seen that the control group of animals under conditions of “feed stress” reduced milk yield, while in the experimental group, which included the product of the proposed composition, the milk yield of the cows remained stable and even increased slightly. It is important that in the experimental group there is no hypoglycemia, which indicates the normalization of metabolic processes.

Example 2

The farm "Agrotechnics" of the Leningrad region. The control group - 100 animals received the usual diet - 8-10 kg of concentrates and 25 kg of silage per day. In the diet of the experimental group (100 goals) for 3 months the product was introduced according to the proposed method of the following composition:

- oligofructose - 200 g

- inulin - 300 g

- sorbitol - 300 g

- easily digestible carbohydrates - glucose, fructose, maltose - 200 g

- phospholipids - 250 g

- anise oil - 10 g / kg, cinnamon oil - 5 g / kg, clove oil - 5 g / kg, yeast hydrolyzate - 200 g / kg, soy hydrolyzate - 200 g / kg. In May, a change in the silo pit occurred, and the new silo did not match for a number of parameters, including by the content of digestible protein. Milk productivity of cows in the control group decreased by 2 l / day. At the same time, in the experimental group (increased milk productivity) did not observe a decrease in milk productivity.

Dosage - 100 g goals / day.

The test data are presented in table.2.

As can be seen from the data in table 2, the proposed method provides stabilization of milk yield in a situation where the quality of the silo is unsatisfactory. Moreover, under these conditions, a high level of glucose in the blood is achieved, which also contributes to an increase in the level of milk yield, since milk lactose is formed from the glucose present in the blood. With hypoglycemia, milk synthesis is reduced. Thus, a combination of several factors important for the formation of milk:

- oligofructose - 100-200 g

- inulin - 200-300 g

- sorbitol - 200-300 g

- easily digestible carbohydrates - glucose, fructose, maltose - 100-200 g

- phospholipids - 150-250 g,

as well as essential oils and amino acid hydrolysates in one product, it solves the problem of stabilizing milk productivity in cows under conditions of “feed stress”.

Example 3

The farm "Agrotechnics" of the Leningrad region. The control group - 50 goals received the usual diet - 8-10 kg of concentrates and 25 kg of silage. In the diet of the experimental group - 50 goals for 3 months introduced the product according to the proposed method of the following composition:

- oligofructose - 100-200 g

- arabinogalactan - 200-300 g

- sorbitol - 200-300 g

- easily digest carbohydrates - glucose, fructose, maltose - 100-200 g

- phospholipids - 150-250 g

- anise oil - 10 g / kg, cinnamon oil - 5 g / kg, clove oil - 5 g / kg, yeast hydrolyzate - 200 g / kg, soy hydrolyzate - 200 g / kg. At the end of May, a change in the silo pit occurred, and the new silo did not match for a number of parameters, including by the content of digestible protein. The milk productivity of cows in the control group decreased by 2.3 l / day. At the same time, in the experimental group did not observe a decrease in milk productivity.

The test data are presented in table.3.

As can be seen from the data in table 3, the proposed method provides stabilization of milk yield in a situation where the quality of the silo is unsatisfactory. Moreover, under these conditions, a high level of glucose in the blood is achieved, which also contributes to an increase in the level of milk yield, since milk lactose is formed from the glucose present in the blood.

- phospholipids - 150-250 g,

as well as essential oils and amino acid hydrolysates in one product, it solves the problem of stabilizing milk productivity in cows under conditions of “feed stress”.
