Description

The invention relates to animal husbandry, specifically to methods for growing and fattening gobies.

One of the urgent problems of the agro-industrial complex is to increase the production of meat, including beef, as the most complete food product, as well as improving its quality.

The standards for growing and fattening young cattle should take into account the need of animals for metabolic energy, dry matter, crude protein, carbohydrates, fats and macro- and microelements and vitamins [1].

In recent years, selenium-containing preparations have been used in animal husbandry, including sodium selenite, DAFS-25 (diacetophenonyl selenide) [2].

Due to the increased toxicity of sodium selenite, organic selenium compounds, for example DAFS-25, are used, as they are less toxic and more accessible to animals. The drug DAFS-25 is introduced into the feed of gobies at the rate of up to 4 mg / kg of feed (for selenium). Putting selenium into the diet helps to intensify the metabolism, slows down lipid peroxidation, and prevents a number of diseases, including associated with selenium deficiency.

A method for fattening gobies is described, which involves introducing the selenorganic preparation DAFS-25 into the general diet at the rate of 3.75 mg of selenium per 1 kg of feed [3]. Gobies were fed up to the age of 15 months. At the same time, the indicators of the effectiveness of fattening in the experimental groups increased in comparison with the control (without entering DAFS-25 into the diet):

- the digestibility coefficient increased on dry matter of the feed by 2.34%, nitrogen-free extractive substances (BEM) - by 3.53%;

- live weight of gobies increased by 4.4%;

- yield of steam carcass at slaughter by 0.8%;

- the output of meat of the highest and first grade by 2.0%;

- dry matter content in meat by 0.69%, incl. protein by 0.07%, fat by 0.58%.

The disadvantages of the method:

- relatively low indicators of the efficiency of growing and fattening of calves, meat quality.

The purpose of the invention is to increase the efficiency of growing and fattening gobies and meat quality. This goal is achieved by the fact that when growing and fattening gobies, a selenorganic preparation “Selenopyran” was introduced into their general diet at the rate of 3.4-3.8 mg of selenium per 1 kg of feed.

"Selenopyran" (9-phenyl-symmetric-octahydroselenoxanthene) - a crystalline substance, approved for use in a number of diseases in veterinary medicine (Temporary instruction on the use of "Selenopyran" for animal husbandry, approved by the deputy head of the department of animal husbandry and breeding 22.07.1997)

"Selenopyran" contains 24% selenium, the drug does not have an unpleasant odor as in the case of using DAFS-25, less toxic. The introduction of the preparation “Selenopyran” into the diet of gobies makes it possible to increase the digestibility of nutrients, the increase in animal mass, the indicators of slaughter and meat quality.

Example.

By the method of pair-analogues, two groups of gobies of Aberdeen-Angus breed of 20 animals each were formed. The experiment was carried out in ZAO Krasnodonskoye of the Volgograd region. The animals of the control group were fed a general diet, the animals of the experimental group were fed a general diet + preparation "Selenopyran" at the rate of 3.7 mg selenium per 1 kg of feed with concentrated feed for a period of 8 to 15 months. Digestibility, gain in live weight, and meat quality after slaughter were taken into account. Digestibility was determined by the chemical composition of feed, feces and urine in the balance experiments according to the "Norms and diets of feeding farm animals" edited by A. Kalashnikov. et al. M .: IPA, 1985.

The results of the experiment are shown in tables.

Table 1 The digestibility rate of nutrients,% Indicators Control group Experienced group Dry matter 65.89 69.34 Bev 73.87 77.64

From the data of Table 1 it can be seen that the digestibility coefficients increased for dry matter by - 3.45%, for BeV - 3.77%.

The live weight of animals increased to 435.59 kg from 416.76 kg, i.e. 18.83 kg or 4.5%.

table 2 Indicators of control slaughter of gobies Indicators Control group Experienced group Weight of fresh carcass, kg 220.42 235.43 Mascara yield,% 55.59 56.42

According to table 2, the calves of the experimental group exceeded the calves of the control group in terms of carcass yield by 0.83%.

Table 3 Varietal composition of pulp of carcasses of gobies Indicators Control group Experienced group Pulp mass, kg 175.05 190.62 Top grade, kg 24.05 26.74 % 13.74 14.03 First grade, kg 95.48 107.24 % 54.54 56.26 Second grade, kg 55.52 56.64 % 31.72 29.71

From table 3 it is seen that in the carcasses of gobies of the experimental group there was more meat of the highest and first grade compared to the control group by 2.55%.

Table 4 The chemical composition of the pulp of carcasses of gobies,% Indicators Control group Experienced group Moisture 68.08 65.21 Dry matter, incl. 31.92 34.79 protein 18.19 18.87 fat 12.76 14.84 ash 0.97 1,08

The meat of the gobies of the experimental group contained 2.87% more dry matter, 0.68% protein, and 2.08% fat.

Table 5 The biological value of the pulp of carcasses of gobies (average sample) Indicators Control group Experienced group Tryptophan, mg% 386.32 391.57 Oxyproline, mg% 98.67 95.81

As can be seen from the data in Table 5, the biological value of the pulp of carcasses of gobies of the experimental group is higher than that of the gobies of the control group.

Table 6 Technological properties of the longest back muscle Indicators Control group Experienced group pH 5.81 5.83 Water retention,% 60.78 62.34 Digestibility,% 34.90 32.75 KTP (culinary and technological indicator) 1.74 1.90

The meat of the gobies of the experimental group had a higher KTP - by 0.16%.

Reducing the flow rate of "Selenopyran" below the proposed leads to a deterioration in the efficiency of bull calf feeding, excess is economically unprofitable.

Thus, introducing into the diet of bull-calves “Selenopyrana” at the rate of 3.7 mg selenium per 1 kg of feed allows to increase the digestibility of feed nutrients, the mass of gobies, slaughter and meat quality.
