The influence of drugs with a synergistic mixture of phencides on the intensity of invasion, morphological blood parameters and leukocyte formula in chicken eimeriosis mixed with colibacillosis

Abstract

In this work, we studied the synergistic preparations phencid and phencid premix prepared by us in doses of 288 mg/kg and 1000 mg/kg to the feed, which reduce the intensity of invasion by almost 4-5 times and their use at the above doses does not negatively affect the morphological parameters and the leukocyte formula of the blood of birds. Considering the relevance, these drugs can be used for the prevention and treatment of these diseases. For this purpose, birds were experimentally infected simultaneously with pathogens of Eimeria and Escherichiosis. As a result, it was found that the tested drugs reduce the intensity of invasion by 4-5 times and do not have a negative effect on the morphological composition of the blood and the leukocyte formula.
