Abstract

FIELD: animal science.

SUBSTANCE: it is necessary to introduce perorally an alcohol-honey extract of walnuts of milk-wax maturity at adding glycine and flower pollen. The preparation should be introduced 5 d before and after the impact of stress factors 30 min before feeding per 10-15 ml/animal daily. As a result of applying the suggested preparation the body weight losses in animals are decreased considerably, the body weight gain is increased along with the quantity and quality of animal production.

EFFECT: higher efficiency of prophylaxis and correction.

Description

The invention relates to the field of animal husbandry and can be used for technological stresses arising during the cultivation, rearing and fattening of young cattle.

The sensitivity of livestock to the effects of technological stresses can be reduced by using tranquilizers (aminosine, chlorpromazine, triftazine, phenozepam, etc.) that contribute to general sedation, eliminate affective reactions that reduce anxiety, anxiety [1]. However, the main disadvantage when using it is the high cost, the short duration of their action, the possibility of accumulation of these substances or their decomposition products in the animal’s body, as well as low efficiency.

A promising way to reduce the negative impact of stress factors is the use of adaptogens - substances that can increase the natural general nonspecific resistance to stress, optimizing the physiological processes inherent in the animal organism, due to its general tonic effect.

Known plant adaptogen heracond [2], which is an alfalfa extract with the addition of trace elements. Erakond contains humic substances, amino acids, monosaccharides and has a balanced composition of trace elements. It was established that the heracond is a phytopreparation with adaptogenic properties, providing activation of the body's protective functions to the adverse effects of technological stresses, which is reflected in the normalization of the physiological status of slaughtered livestock and the reduction in meat productivity losses.

The disadvantage of this method is the high cost of the Heraclea due to the complexity of its manufacture and low efficiency.

Known plant adaptogen - licorice root powder, which is fed to animals with feed in an amount of 3 g per kg of live weight per day (about 1 kg per head per day) 8 days before transportation [3].

The disadvantage of this method is low efficiency and a large number of adaptogen used.

The technical result is the search for an effective way to reduce the negative impact of technological stresses on the animal organism during the period of cultivation, rearing, feeding and transportation.

This is achieved by using an adaptogen of plant origin - an alcohol-honey extract of walnuts with milk-wax ripeness with the addition of glycine and flower pollen (hereinafter the drug). The drug is administered orally to animals 5 days before and after exposure to stress factors (formation of groups, changing places of detention, weighing, veterinary processing, castration) 30 minutes before feeding, 10-15 ml per head per day.

The drug - the strongest adaptogen, immunomodulator - significantly enhances the anti-stress protection of the animal organism, acting by the mechanisms of a natural tranquilizer and antidepressant. The proposed range of the amount of drug administered is optimal to achieve the desired therapeutic effect.

Example.

To test the effectiveness of the drug to reduce the effects of technological stresses in young cattle, 36 calves at the age of 1 month were selected according to the principle of analogs and divided into two groups: experimental and control, 18 animals each. Calves of the experimental group 5 days before and after exposure to stress factors were orally administered 12 ml of the drug per head per day, 30 minutes before meals. Calves of the control group were fed, along with feed, licorice root powder in the amount of 3 g per kg of live weight per day for 8 days before exposure to stress factors.

Studies have shown that with the addition of drugs in calves, the stress state significantly decreased, although it was not completely removed. In particular, during the formation of the groups (and this is also due to a change in the conditions of detention), the decrease in the growth rate amounted to 12.3% in the control group and 5.8% in the experimental group.

Castration at the age of 6 months had the most significant effect on the growth rate of young animals, as a result of which the average daily growth in the control group decreased by 339 g (35.3%), and in the experimental group by 265 g (26.7%). The research results are shown in table 1.

After castration in animals of both compared groups, the morphological and biochemical composition of blood noticeably changed, but to a greater extent this was observed in control young animals. Thus, the content of red blood cells in calves of the control group increased by 12.9%, and the experimental - by 3.9%, white blood cells - by 10.2% and 3.2%, respectively, hemoglobin - by 5.2% and 1.7% , total protein - by 5.6% and 1.9%.

The results of hematological studies are presented in table 2.

The use of the drug significantly reduces the effects of technological stresses on young cattle during the period of growing, growing and fattening.
