Use experience of coniferous and phytogenic feed additives in treatment and prevention of eimeriosis in calves

The purpose of the research is to determine the therapeutic and prophylactic efficacy of long-acting coniferous and phytogenic feed additives against eimeriosis in calves under traditional rearing conditions.Materials and methods. Eimeriosis of calves aged 50 to 60 days was analyzed on a livestock farm in the Kirovo-Chepetsk District of the Kirov Region from April to May 2023. Coniferous and phytogenic feed additives “Coniferous and phytogenic immune modulator for baby calves” and "Coniferous and salicylic feed additive" (LLC STC Khiminvest) were used as treatment and prevention drugs. To diagnose eimeriosis in calves and monitor the treatment effectiveness, we performed clinical observations, thermometry, and coprological surveys pursuant to GOST 25383-82 as housed by the Diagnostic Laboratory of Veterinary Parasitology of the VSATU.Results and discussion. The “coniferous and phytogenic immune modulator for baby calves” was found to have 100% therapeutic and prophylactic effectiveness against Eimeria bovis and E. ellipsoidalis dwelling in calves during the motherbonded rearing. The “coniferous and salicylic feed additive” showed a 100% positive effect against E. ellipsoidalis. Due to eating qualities, both feed additives were well eaten by animals and helped to improve diarrhea symptoms.
