The influence of para-aminobenzoic acid vitamin on the leucocytes and their phagocytic activity in blood of rabbits of "silver" breed in the period of autumn

The purpose of the research was to study quantitative structure of leukocytes and their phagocytic activity and also to differentiate leucocytes blood count of rabbits of experimental and control groups in an autumn season at using paraaminobenzoic acid. The research problem was to estimate the effect from the impact of para-aminobenzoic acid on an organism of rabbits at autumn period of a year. During the research 20 rabbits at the age of 2.5-3 months were divided into control and experimental groups up to 10 heads in each. The rabbits were held on a rabbit farm in the village of Kamarchaga in cages in the open air. The diet of feeding of all animals met feeding standards, but the animals of experimental group in addition received para-aminobenzoic acid vitamin 1 time a day within 10 days in morning feeding numbering 10 mg on 1 kg of live weight. On the 11-th day after the addition into a diet of feeding of paraaminobenzoic acid in blood of rabbits of control and experimental groups the quantity of leukocytes was counted, the calculation of leukocyte formula was made and phagocytic the activity of leukocytes of blood was defined...
