this experiment was conducted to investigate the effects of using protexin, propionic acid growth promoters, and a blend of them on broilers performance. in a completely randomized design, three hundreds and twenty unsexed 1-d-old chicks were divided into four groups. dietary treatments were consisted of 1) control diet without any supplement, 2) the control diet + 0.01 % protexin, 3) the contr...

In 2006, the European Commission banned use of antibiotic promoters in animal feed. However, there is a new situation poultry disease where it necessary to study feed additives, which can overcome diseases that were previously controlled through addition antibiotics and antimicrobial growth Therefore, trehalose was investigated determine whether impacts performance pathogenic bacteria (C. jejun...

Recent outbreaks of food-borne diseases highlight the need for reducing bacterial pathogens in foods of animal origin. Animal enteric pathogens are a direct source for food contamination. The ban of antibiotics as growth promoters (AGPs) has been a challenge for animal nutrition increasing the need to find alternative methods to control and prevent pathogenic bacterial colonization. The modulat...

Simple, sensitive analytical methods are required for routine monitoring of banned substances, such as antibiotics that are added to animal feed to prevent disease and promote growth. This Application Note demonstrates the quantifi cation of two growth promoters, olaquindox and carbadox in animal feedstuff using the Agilent 1260 Infi nity Binary LC system. The 10x higher sensitivity of the 60 m...
