Efficacy of Bio-Zinc medicinal preparation in treating cattle with Rusterholtz ulcer

Abstract

The issue of treating cattle with Rusterholz ulcer is discussed. The study involved Holstein-Friesian cows at the age from 2 to 4 years with body weight of 400-500 kg with hooves affected by Rusterholz ulcer. The animals were selected from one physiological group - the dairy herd. The efficacy of the combined liniment based on beech tar and Bio-Zinc product in a dose of 0.2 mL kg was studied. When comparing clinical data to evaluate the efficacy of using various treatment regimens against Rusterholz ulcer, it was found that wound healing with the use of the combined liniment and Bio-Zinc was more intensive. The greatest therapeutic efficacy was observed when treating the cows of the second trial group using the combined liniment and Bio-Zinc at a dose of 0.2 mL kg; the efficacy made 100%. Recovery occurred on the day 17.8 ± 0.80 which was earlier than in the control and first trial groups by 12.4 and 5.0 days, respectively. When evaluating the clinical signs, positive dynamics was observed in all trial groups. This was expressed in the appearance of appetite and rumination, easier standing up from the lying position, increasing active hours, and the absence of lameness. Milk yields were the highest in the second trial group where the treatment regimen with combined liniment and bottle-feeding with Bio-Zinc was used; the milk yields reached 40.04 ± 0.41 L (p < 0.001) which was higher than that in the control and first trial groups by 9.14 and 2.46 L, respectively.
