Description

Description of the invention

The useful model belongs to the field of animal husbandry, in particular to the feeding of farm animals, namely to 2 ways of increasing the productivity of fattening cattle and improving the quality of their products in conditions of a lack of deficient trace elements in feed and can be implemented in cattle farms of various forms of ownership aimed at beef production.

The well-known "Method of increasing the productivity and quality of products of fattening livestock" (patent of Ukraine

Мо33994А), which consists in the fact that feeding experimental bulls with a mixture of cobalt methionate (0.05 mg/kg 70 live weight) and iodine (0.05 mg/kg live weight) contributed to an increase in their average daily growth by 33.690, an improvement in the chemical composition of meat and increasing its calorie content by 5,395.

However, with the help of the known method, it is possible to eliminate the deficiency of only 2 microelements (cobalt and iodine), while the lack of other microelements causes inhibition of the full manifestation of the genetic potential of fattening cattle. 12 Also known is the "Method of increasing the productivity of fattening steers and improving the quality of their products" (patent of Ukraine for a utility model Mo42578А|.

The method includes the use of a mixture of chelated compounds of trace elements cobalt, iron, selenium, copper, iodine with the amino acid methionine to eliminate the lack of microelements by adding to the diet. The disadvantage of the method is its insufficient efficiency, since the biochemical processes occurring in the body are not taken into account.

The closest in essence to the method that is claimed is "Method of correction of metabolism and increase of productivity of fattening bulls in conditions of micronutrient deficiency" | patent of Ukraine Mo53285А1.

The method includes introducing into the diets of fattening animals a mixture of chelated compounds of trace elements copper, iron, manganese, cobalt with the amino acid cysteine. The method ensures the normalization of metabolic processes in the body of fattening cattle and increases their productivity in conditions of micronutrient deficiency by 47.3905. with

The disadvantage of the known method is insufficient effect of the mixture of cysteines of microelements on the quality of the obtained products.

The method proposed by us eliminates the shortcomings of the closest analogue and ensures high meat productivity of fattening cattle while simultaneously obtaining beef with a better chemical composition, biological value and physical and sanitary properties compared to the known method. "Her

The useful model is based on the task of creating an effective method of increasing the productivity of fattening cattle in conditions of micronutrient deficiency and improving the quality of beef, available for use in cattle fattening farms with different forms of ownership. "AND

The technical result is achieved by adding sodium humates to the mixture of chelated salts of microelements with cysteine in the following ratio of components in the composition of the mixture in mg/kg of live weight per day: - iron cysteinate - 0.01-0.03; cobalt cysteinate - 0.005-0.015; copper cysteinate - 0.01-0.03; manganese cyteinate - 0.01-0.03 and sodium humate 300-500. The mixture is dissolved in water, mixed with basic fodder, and fed to cattle during the fattening period. "

This form of introduction of a mixture of trace elements with sodium humate into the ration ensures an increase in productivity, contributes to the improvement of biosynthetic processes in the animal body due to better assimilation of nutrients in the ration, improves the chemical composition and physicochemical properties of meat, as it contributes

With" the additional intake of deficient microelements in the body of fattening cattle, which indicates the correction of their metabolism in conditions of lack of deficient microelements.

Sodium humate introduced into the feed of fattening cattle has a positive effect on the growth and development of rumen microflora, promotes the synthesis of biologically active substances, in particular vitamins, amino acids, which take an active part in the synthesis of meat proteins. "" The introduction of cysteines of microelements into the diet of fattening animals ensures increased productivity, improvement of biosynthetic processes in the animal's body due to better assimilation of cysteines compared to other salts of microelements. "iz" 20 The simultaneous administration of sodium humate with a mixture of cysteines of microelements provides optimal conditions for the growth and development of ruminal microorganisms, and also promotes the biosynthesis of biologically active substances by them, which, in turn, have a positive effect on the metabolism in the body of fattening cattle and, in particular, , on the quality of their products.

The technical solution (Kravtsiv R.Y., Paska M.3. "Method of correcting metabolism and increasing the productivity of 29 fattening bulls in conditions of micronutrient deficiency" patent of Ukraine Мо53285А 7 А2ЗК1/16) contains the largest number of essential features common to the declared solution: - elimination of trace element deficiency in the diets of fattening cattle by adding to their diets during the period of fattening a mixture of trace elements iron, cobalt, copper, manganese in the form of their chelates with the amino acid cysteine.

The implementation of the declared useful model is carried out as follows: 1. Determine the supply of microelements (copper, iron, cobalt, manganese) to the animals of this farm. For this purpose, feed and blood tests are conducted to determine the content of microelements. 2. Calculate the need for a separate trace element according to the following formula: n - KAMmADyaT

P - the need for trace elements; because K is the number of varin;

M - live weight of animals;

D - dose of trace elements in mg/kg of live weight;

T - duration of feeding in days.

Chelated compounds of microelements with the amino acid cysteine, weighed according to the calculations, are mixed well with the addition of sodium humate in a dose of 300-50Omg/kg of body weight, dissolved in water, and fed to animals with fodder during the fattening period.

The effectiveness of the proposed method and its advantage over the known (closest analogue) is confirmed by examples of specific implementation. 70 Example 1

As a result of preliminary studies, low content of certain trace elements, namely: iron, copper, cobalt, manganese, was found in the feed of Halychyna LLC of the Zhovkiv district of the Lviv region. The data of these studies are shown in Table 1.
