1. Introduction
In the poultry industry, enteric bacterial pathogens pose a threat to intestinal health and can contribute to the transmission of zoonotic diseases [1,2], increased mortality in poultry flocks, reduced feed efficiency, decreased rate of body weight gain and, therefore, increase in total production costs [3,4]. Salmonella infection and necrotic enteritis (NE) produced by Clostridiu ...

Introduction
Distillers dried grains with solubles (DDGS) are by-products obtained during production of biofuels as renewable energy sources. During starch fermentation from cereal grains, ethanol and CO2 are produced; meanwhile, the remaining nutrients are concentrated in the DDGS fraction (Singh et al., 2005). Corn is the main cereal used in ethanol production in the United States; however, oth ...

INTRODUCTION
The continuous tendency to reduce the use of antibiotic growth promoters (AGP) in poultry production, due to social concern about generation of antibiotic-resistant bacteria, has resulted in the crucial necessity to find economically viable alternatives that can maintain optimal health and performance parameters under commercial conditions (1, 2). One possible substitute for AGP tha ...
