Microbiological studies of feed and faeces of fatteners fed mixtures containing naked oat and permutite

摘要

Quantitative and qualitative microbiological studies of feed mixtures and faeces of fatteners with body weight approximately 70 kg receiving complete mixtures: group I (control) - 55 percent barley, II - 55 percent naked oat, III - 55 percent nakedoat + 3 percent permutite were conducted. All mixtures were supplemented with the same protein concentrate for fatteners. It was found that feeding the fatteners with mixtures containing naked oat had a favourable effect on the composition of the faecalmicroflora, with increased participation of Lactobacillus spp. bacteria. The addition of permutite did not visibly affect the composition of the microflora and the observed differences between the groups can be attributed to the species of cereal in thefeed mixture, with naked oat being far more favourable than barley. The addition of permutite seems to have a beneficial effect on the condition of the faecal matter of these animals, which contained a larger number of Saccharomyces spp. cells.
