Two experiments were carried out to investigate the capacities of pigs for bulky feeds. In Expt 1 fifteen pigs were offered, from 12 to 25 kg live weight, ad lib. access to one of five feeds which were made by progressively diluting a high-quality feed with wheat bran. Intake initially increased, and then declined, as the proportion of wheat bran was increased. The pigs became better able to ac...

Background: Aflatoxins (AF’s) are secondary metabolites produced by certain species of fungi on grains and animal feeds. Because of serious impact of AF’s on health, they should be monitored closely in potentially hazardous foods and feeds. Method: In this study, AF’s in imported animal feeds including cereals, corn gluten and meals (pastes derived from the cotton, colza and sunflower seeds) f...

OBJECTIVE Contamination of feeds with pathogenic microflora and mycotoxins constitutes a serious threat both for animals and humans. The aim of the study was to determine the degree of risk of the occurrence of microscopic fungi, selected bacteria and mycotoxins from the trichothecene group in poultry feeds in western Poland. RESULTS In feed mixtures, the concentration of ergosterol (ERG), be...
