Mycotoxins are pervasive and dangerous fungal metabolites in feedstuffs formed in the field pre-harvest and under sub-optimal storage conditions post-harvest. Consumed by livestock and poultry, they can reduce performance and alter metabolism, possibly causing pathological states-mycotoxicoses-in both animals and humans. Mycotoxin contamination can result from a range of mycotoxin-producing fungi depending upon the feedstuff source,…
Žive ćelije kvasca su široko rasprostranjene u prirodi, a u ljudskoj upotrebi su nekoliko hiljada godina. Obično se vezuju za pravljenje vina, piva, fermentirano povrće ili umake, kao i za pekarske proizvode. Žive ćelije kvasca se klasifikuju kao jednoćelijski sojevi kvasca i nisu stalni stanovnici u organizmima domaćih životinja. Ipak, izolovane su iz digestivnog trakta…
Because of their pH-reducing and antimicrobial effects, gut acidifiers appear to offer promise as substitutes for antimicrobial growth promoters where the use of the latter is banned or severely restricted. In a recent case study, the use of a gut acidifier improved eggshell quality in a broiler breeder flock. Antibiotic growth promoters (AGP) have been…
