Description

The invention relates to agriculture, in particular to a method for increasing the productivity of calves.

Increasing the productivity of farm animals is one of the primary tasks at the present stage of development of society. This involves rational feeding and the use of biologically active substances that activate digestive and metabolic processes in the animal’s body, facilitating the conversion of feed nutrients into an digestible form.

Currently, adaptogens of plant origin are often used to prevent various stresses in animal husbandry. The most famous of them are Echinacea purpurea, ginseng, golden root, etc. (Gotovsky D. G., 2013).

There is a known method of increasing the growth rate of newborn calves based on the use of a mixture of extracts of Leuzea safflower and stinging nettle. Inclusion in the diet of 14-day-old calves for 14 days once a day, 30 minutes before feeding, of a mixture of extracts of Leuzea safflower at a dose of 0.125 mg/kg live weight of the calf and stinging nettle at a dose of 7.0 mg/kg live weight of the calf provides an increase live weight by 4.6% (Zubova T.V., Grachev S.Yu., 2021).

Introduction into the body of young horses of the Oryol trotting breed
in combination with the drug Sedimin intramuscularly and a phytobiotic feed additive based on Echinacea purpurea extract with feed causes a significant increase in the average daily increase in body weight by 20.8-75.0%, this also causes an increase in the blood of one-year-old young horses of the Oryol trotting breed compared to the control: the number of erythrocytes - by 7.6-36.2%, hemoglobin - by 4.6-12.4%, leukocytes - by 1.0-15.6%, total protein content by 0.8-10.1% ( Dyadichkina T.V., 2018).

It is proposed to feed laying quails under production conditions during the laying period with selenium in the form of the drug “Selenium East” at a dose of 125 g/t of feed and iodine in the form of the drug “Yoddar-Zn” at a dose of 62.5 g/t of feed. The composition of the feed additive with the preparations makes it possible to increase the gross yield of eggs by 5.6%, egg production for initial and average laying hens by 4.7%, the intensity of egg laying by 3.6% and reduce feed costs by 5.3% (Bagno O.A. , Alekseeva A.I., 2015).

A feed composition for animals, especially poultry, has been developed containing benzoic acid in combination with a mixture of at least two active compounds selected from the group consisting of thymol, eugenol and piperine (Frechner Marko, Gadient Martin, 2008).

Premix for laying hens, containing vitamins, macro- and microelements, a balanced complex of amino acids, additionally contains iodine in organic form in the form of the feed additive "Fukolam S" in the amount of 35 g per 1 kg of premix and selenium in organic form in the form of the drug "Sel" -Plex" in the amount of 0.051 g per 1 kg of premix (Naumova L.I., Ovchinnikova N.A., 2019).

Patent RU 2780229, publ., was chosen as the closest analogue. 09/21/2022, there is a known method for increasing the productive qualities of young cattle, which involves introducing into the main diet of animals an extract of Echinacea purpurea, obtained using water-ethanol extraction at a dose of 4.0 g per head per day.

The disadvantages of the presented preparations are: the complexity and labor-intensive process of feeding extracts and micronutrients to animals, the insufficiently high productivity and safety of farm animals.

The technical result of the present invention is to increase the productive qualities of calves by enriching the basic diet of animals with a phytogenic feed additive based on extracts of medicinal plants in combination with the Albit BIO feed additive.

A phytogenic feed additive based on extracts of medicinal plants Echinacea purpurea and Leuzea safflower was obtained by water-ethanol extraction followed by low-temperature vacuum drying according to patents RU 2724531, RU 2739625.

The active ingredients of the phytogenic feed additive are the following biologically active substances: alkaloids (1.30%), flavonoids (2.12%), lignins (17.5%), tannins (5.20%), coumarins (2.54%). ), ascorbic acid (40%), inulin (3.5%), organic acids (1.2%).

The feed additive "Albit BIO" is a product of microbiological synthesis: lysed biomass (autolysate) of the soil saprophytic fungus Cephaliophora , enriched with selenium, iodine, magnesium, calcium and other auxiliary microelements.

The method is carried out as follows

For young cattle from 3 months of age, a phytogenic feed additive based on Leuzea safflower extract at a dose of 5 g per head per day, Echinacea purpurea extract at a dose of 4 g per head per day, and the drug " Albit BIO" for 10 days at a dose of 5 ml per head.

Execution example

Experimental studies were carried out at Lebedi LLC, Promyshlennovsky district, on young calves of the black-and-white breed.

From the beginning of the main period of the experiment (from 3 months of age), the housing and feeding conditions for the groups were the same, but the animals of the experimental groups were given various drugs and extracts in addition to the main diet according to the experimental scheme (Table 1). The main diet on the farm was wheat bran.

Table 1 – Scheme of scientific and economic experience

Group Number, goals Method and dose of administration of drugs and extracts Control 10 Basic diet (BR) Experienced 10 (OR) + Leuzea safflower extract ( Rhaponticum carthamoides ) at a dose of 5 g per head per day + Echinacea purpurea extract at a dose of 4 g per head per day + Albit BIO at a dose of 5 ml per head for 10 days

The research results are presented in Table 2.

Table 2 – Growth rate of young cattle, M±m

Index Group Control Experienced Number of animals, goal 10 10 Duration of experiment, days 90 90 Live weight at 90 days of age, kg 77.6±2.82 76.9±2.18 Live weight at the end of the experiment, kg 155.0±2.90 160.1±1.98 Average daily increase, g 860±9.82 924±9.89 Gross gain, kg 77.4 83.2

Thus, the average live weight at the end of the experiment was higher in the experimental group by 3.3% (P>0.05). The average daily increase was higher in the experimental group by 7.4% (P>0.05) compared to the control.

Thus, based on the above, we can conclude that feeding a phytogenic feed additive based on extracts of Echinacea purpurea and Leuzea safflower at a dose of 4 and 5 g, respectively, per head per day in combination with the drug "Albit BIO" at a dose of 5 ml per head within 10 days it has a positive effect on the productive qualities of calves.
