Description

The invention relates to agricultural production, in particular to livestock, and can be used to reduce the loss of meat products under technological stresses, for example pre-slaughter preparation of young cattle.

It is known that under technological stresses that arise during the period of rearing, fattening and sale of young animals, up to 30% of meat production is lost (1). Therefore, in practice, various pharmacological tranquilizers, thyreostatic drugs, antioxidants, antibiotics, organosilicon compounds, and others are used to reduce the stress on the animal organism (2,3). However, in most cases, they have a short-lived effect, are scarce and expensive.

It is known that fodogrizin is used as an agent for the prevention of transport stress in animals (2).

It is effective only in case of feed stress and therefore has not been widely used as an anti-stress drug.

The essence of the invention lies in the fact that for the first time as a tool for the prevention of transport stress in young cattle, the biological product "Lactobifadol" is used a month before exposure to the stress factor at a dose of 100-200 mg / kg body weight per day.

Lactobifadol is a veterinary preparation made from living bacteria of the species B.adolescentis and L.acidophilum, it synthesizes B vitamins, biotin, vitamins K, C and others in the body, and is currently used exclusively for the prevention and treatment of gastrointestinal diseases ( 4). It is used for the first time as an anti-stress drug.

Concrete example

In Klyuchevoe JSC, Orenburg Region, 35 calves of the Simmental breed were selected, of which seven groups were formed by the principle of analogues - control and six experimental. The difference was that, in contrast to the control animals of the I, II, III, IV, V experimental groups, a month before slaughter, probiotic lactobifadol was additionally fed in the amount of 50, 100, 150, 200, 250 mg / kg of live weight, respectively, and VI - biopreparation of foddergrizin at a dose of 12,000 units per head per day. The conditions of detention, the general level of feeding and the dietary structure of the experimental young animals of all groups were identical. The animals were on the feedlot. They were transported to the meat processing plant on specially equipped vehicles. Transportation distance 110 km.

Feeding animals with lactobifadol helped to reduce the loss of live weight during transportation by an average of 32 kg or 11.9%. If in the control group they were 26.9 kg, then in the experimental group - on average 23.7 kg. The indicators to reduce the loss of meat products during transport stress using the biological product Lactobifadol are presented in table. 1.

The smallest losses of cultivated products were observed in young animals of the II, IV and especially III groups. In particular, in the latter they amounted to 22.5 kg (5.12%), while in the control - 26.9 kg (6.14%), in the first one - 24.6 (5.63%), in II - 22.9 (5.21%), in IV - 23.0 (5.25%), in V - 24.6 (5.64%) and in VI - 24.4 kg (5.57 %), that is, when feeding bulls of the test drug at a dose of 150 mg / kg, the decrease in live weight during the transportation period was more significant than in other groups.

For the period of pre-slaughter 24-hour fasting, the loss of live weight in the control group was 17.8 kg or 4.33% of the initial level, whereas in the experimental group it was on average 15.2 kg or 3.68%. And in this case, the smallest they were in the III experimental group - 14.7 kg (3.52%).

The total loss of live weight during the pre-slaughter period (transportation and fasting) in the control group amounted to 44.7 kg or 10.20% of the removable weight, and in the experimental group, on average 38.9 kg (8.89%). Abbreviation

loss of live weight when feeding lactobifadol at a dose of 50 mg / kg was 4.9 kg (1.08%), 100 - 6.8 (1.57%), 150-7.5 (1.74%), 200- 6.3 (1.44%), 250-4.4 (0.96%), fodogrizin at a dose of 12,000 units - 4.8 kg (1.09%).

Feeding the experimental young of lactobifadol, and in the VI group of fodder grisin, allowed to increase the mass of carcass and internal fat in animals of I, II, III, IV, V and VI of the experimental groups, respectively, by 5.3 (2.5%), 2.0 (0, 9%), 8.3 kg (3.9%), 3.0 (1.0%), 5.3 (2.5%), 4.5 kg (2.1%), and at 0, 7 (6.1%), 0.3 (2.5%), 0.6 (5.2%), 0.2 (1.7%), 0.5 (4.3%), 0, 6 kg (5.2%).

In terms of slaughter yield, control animals were inferior to young animals of the first experimental group by 0.76%, II by 0.47%, III by 0.95%, IV by 0.68%, V by 0.44% and VI experimental - by 0.29%.

In the bull-calves of the experimental groups, especially II and III, there were also a smaller number of confiscations during the processing of carcasses, which indicates their better slaughter preparation.

The research results showed that the stress state caused by transportation has some effect on hematological parameters, characterizing the stress of the body. The morphological and biochemical composition of blood is given in table. 2.

After transportation, in the gobies of the control group, the blood erythrocyte content increased by 9.9%, white blood cells - by 7.5%, hemoglobin - by 7.0%, total protein - by 3.4%, lipids - by 7.6%, sugar - by 23.7%. This indicates both an increase in stress loads of protein, lipid and carbohydrate metabolism, as well as dehydration (moisture loss) of the body. The latter is confirmed by an increase in blood hematocrit by 7.87%.

The normalization of the physiological state in animals under the influence of transport stress on them was facilitated by the feeding of the test drug. Moreover, the smallest change in the blood composition of gobies was observed in the III experimental group, young animals of which received in addition to the diet 150 mg / kg of live weight of the probiotic lactobifadol. In this case, we can only talk about a tendency toward an increase in hematological parameters when exposed to vehicle

stress factor, since the difference between the initial level and after the transportation of animals was statistically unreliable. A somewhat similar change in blood composition was observed in young animals of the II and IV experimental groups, although in this case the difference before and after transportation was more noticeable.

The positive effect of lactobifadol on the animal’s body is more pronounced compared to the analogue and is explained by the fact that it exhibits pronounced antagonism in the gastrointestinal tract against pathogenic and conditionally pathogenic microbes, thereby creating a favorable environment for the development of necessary organisms, enhances enzymatic activity, and also metabolism, synthesizes B vitamins, vitamins K and C, biotin, increasing the overall immunological system of the body and its resistance to stress factors.

The use of lactobifadol as an anti-stress drug is economically beneficial. Moreover, the greatest effect is achieved when feeding animals a dose of 150 mg / kg of live weight. Additional profit in this case is an average of 206 rubles. per animal, while at 100 mg / kg - 170 rubles., 200 mg / kg - 40 rubles., and when feeding core-moghrizin - 154 rubles.

Thus, the use of Lactobifadol as a means of preventing transport stress in young cattle helps to normalize the physiological state of the body, reduce the loss of meat products, as evidenced by the results of hematological studies and the results of control slaughter, respectively. Moreover, the highest rates are achieved when using this drug in a dose of 100-200 mg / kg body weight per day.
