| OCA16. Annotation of the output in English | The aim of the study was to assess the effect of the addition of humic substances (HS) in combination with urea on pH, ammonia content, concentrations of total volatile fatty acids (VFAs), protozoa population, amylolytic and cellulolytic activity in the rumen of sheep. The basic daily ration consisted of grass hay, cereal grains and the addition of 10 g of urea. Humic substances were applied at a dose of 20 g/day per animal in the experimental group on day 2–18. The results revealed that HS increased ammonia concentration, while the total VFAs concentrations, pH values of rumen fluid as weel as amylolytic and cellulolytic activity were not changed. Results suggest humic substances addition with urea as a non-protein dietary nitrogen source may improve nitrogen retention in the rumen, but there was no impact on VFAs production. The feed intake of HS with urea had significantly positive effects on the protozoal population in rumen fluid. |
