Application of «Lithosorbs» to goats for treatment of udder

Abstract

The aim of the study was to investigate the effect of «Lithosorb» on the sanitary quality of goat's milk. For the experiment, four groups of dairy goats were formed by 5 goats in each. During the week, 2 times a day after milking, «Lithosorb» (zeolite activated by silver nanoparticles) with different ointment bases (for the first group of goats were pork fat, for the second one – peach oil, the third – vaseline oil, the fourth – vaseline). The external use of «Lithosorb» with different ointment bases caused a toxic effect on the mammary gland of goats, which led to increase of bacterial contamination and the somatic cells count in milk. The somatic cells count in the goat's milk of the first group slightly increased, and in the second, third and fourth groups increased by 1,7, 2,5 and 5,6 times respectively. Bacterial contamination of goat milk increased in the first group by almost 4,8 times, in the third group – by 2,8 times, in the fourth group – by 7 times, and only in the second group it decreased by 2 times.
