    Hoof pathologies are among the most widespread orthopedic disorders in dairy cattle and are a major contributor to reduced animal welfare and productivity. The present study investigated the prevalence, clinical presentation, and treatment outcomes of the most common hoof lesions – digital dermatitis (Mortellaro’s disease), Rusterholz ulcers, purulent pododermatitis, and interdigital dermatitis – across multiple dairy farms in Ukraine. Clinical examinations and therapeutic procedures were performed on more than 9,800 cows from 7 farms during 2022–2023. Diagnosis was conducted during scheduled functional hoof trimming using an orthopedic crush and was confirmed based on lesion morphology, presence of exudate, odor, and pain response. A locally formulated topical powder composed of copper sulfate, zinc oxide, iodoform, and potassium permanganate was applied to purulent –necrotic lesions and compared with a control treatment using a commercial chemi-spray. Therapeutic efficacy was evaluated by lesion healing dynamics and locomotion scores (AHDB system) on days 3, 14, 21, and 45. Digital dermatitis was identified as the predominant lesion, accounting for 50–66% of all diagnosed hoof disorders. The locally formulated powder showed markedly superior therapeutic performance relative to the chemi-spray, accelerating tissue repair and improving locomotion, with full recovery achieved in 86.7–100% of treated cows, depending on farm and lesion type. These findings confirm the persistently high prevalence of hoof diseases in dairy herds and demonstrate the clinical advantage of an affordable, locally prepared treatment formulation. Routine functional trimming, early lesion detection, and evidence-based local therapy remain critical components of effective lameness management in modern dairy production systems

    The spreading of cattle gastro-intestinal tract helminthoses on farms of Poltava region
    (2025) Latukhin, O.; Kruchynenko, O. V.; Кручиненко, Олег Вікторович
    Parasitic diseases of the ruminants’ gastro-intestinal tract are widespread all over the world, particularly in Ukraine, causing considerable economic losses to livestock farms. Invasive pathogens infest animals of all age groups and often create mixed invasions, which have complex interconnections with the host’s organism. Among cattle gastro-intestinal tract helminthoses, digestive tract strongylidoses and dicrocoeliasis are the most wide spread. The purpose of the paper was to study the spreading and peculiarities of the cattle gastro-intestinal tract helminthoses’ development on the farms of Poltava region. The material for the research was the reporting documentation of the Main Department of State Food Consumer Service in Poltava region as to epizootic situation concerning cattle helminthoses. Own coproovoscopic studies were conducted in the laboratory of the Department of Parasitology and Veterinary-Sanitary Expert Examination of Poltava State Agrarian University and on individual farms in Poltava region. The composition of the invasions’ causal agents parasitizing the cattle's gastrointestinal tract was determined, as well as the degree of their infestation and the peculiarities of helminthoses’ development. The statistical data show the considerable spreading of gastrointestinal tract paramphistomatoses, dicrocoeliasis, and strongyles among the cattle. It has been demonstrated by the conducted research that helminthic fauna is represented by Dicrocoelium dendriticum (Rudolphi, 1819), Paramphistomum genus, Fasciola hepatica Linnaeus, 1758 and the nematodes of Strongylida, Trichuris genus and Toxocara vitulorum (Goeze, 1782). According to the conducted study results, it was shown that the average prevalence of infection in animals with the pathogens of gastro-intestinal tract helminthoses made 47.3 % (207/438). The highest EI indicators in the examined animals were in case of the digestive tract stongyles’ (14.15 %) and dicrocoelia (8.44 %) parasitizing. The highest intensity indicators were observed in case of the digestive tract strongyles’ (283.3±41.15 eggs/g of feces) and dicrocoelia (27.5±4.1 eggs/g of feces) parasitizing. It was revealed that two-component infections prevailed over three-component ones
