The effect of Phytostimplus on blood biochemical parameters, average daily growth and disease resistance of calves

The purpose of the research is to study the effect of the Phytostimplus supplement on the clinical and physiological status, average daily growth and viability of calves during the dairy growing period. The phytobiotic contained an extract from three herbs (safflower rhaponticum, crowned sickle, viscose meadowsweet) and lactic acid microorganisms dried lyophilically. The work was carried out in 2023. The experiment involved calves of the Holstein breed, starting at the age of 2 days. Experimental and control groups of 10 heads each were formed. In the control group, the calves were kept on a regular diet, without the use of any drugs. The additive was soldered to calves of the experimental group at a dose of 30.0 ml / head per day after preliminary dilution in water. The duration of the experiment was 2 months. Thirty days after the start of the experiment, the albumin in the calves of the experimental and control groups exceeded the reference values by 17.8–18.1 %. In both groups of calves, α-globulin decreased in comparison with the physiological norm by 3.3–4.1 %, γ-globulin – by 6.0–6.2 %. A decrease of β-globulin by 5.5 % was observed in animals in the experiment. The rest of the studied blood parameters of calves (urea, zinc sulfate test) in both groups were within the normal range and did not differ significantly. By the end of the experiments, the total protein in the calves in the experiment exceeded the indicator in the control by 30 %, albumin – by 8.1 %, γ-globulin – by 4.9 %, while there was a decrease in α-globulin by 8.6 %, β-globulin – by 4.4 %. The studied parameters did not exceed the limits of the physiological norm. The duration of treatment of enteritis in calves in the experimental groups turned out to be less than in the control with Phytostimplus by 0.7±0.2 days. The safety of animals by the end of the experiments was 100 %. The average daily increase in live weight of calves after the use of phytobiotics for 60 days exceeded that in the control by 4.9 %.
