IntroductionThe chicken gastrointestinal tract (GIT) harbors a very diverse microbiota, dominated by Bacteria, that influences health and growth performance of chicken. A healthy microbiota provides nutrients to the host and promotes competitive exclusion [1]. The composition of the GIT microbiota differs according to diet, age and genotype of hosts as well as the portion of the intestinal tract, ...

1. IntroductionFor more than 50 years, antibiotic growth promoters (AGPs) have been used in agricultural animal production as a means to increase growth performance through maintained animal health and improved feed efficiency [1]. During the last decades, global concern about development and transference of antimicrobial resistance from animal to human strains is rising [2]. The benefits of AGPs ...

Previous studies showed that inclusion of polyphenol-rich plant extracts in feed improves performance in ruminants, but the effect may vary depending on the dosage used. It has been shown that polyphenols modify the digestive process through modulation of gastrointestinal microbiota and bypass of protein digestion. The rumen houses a highly complex microbiota which is able to convert indigestible ...

Phytogenic compounds, probiotics and organic acids are used in broiler feeds as an option to AGPs due to their ability to emulate properties of antibiotics. This study’s goal was to compare a field AGP (virginiamycin 100 g/MT) program (T1) with two antibiotic free programs: Lactococcusbased probiotic+yeast MOS+a blend of Italian Chestnut-C/Argentine Quebracho-Q bioactive ex ...

1. Introduction The demand for poultry products has grown exponentially in recent decades and it is estimated that production will reach 130 million tons of chicken meat in 2020, when it will become the most consumed animal meat in the world [1]. Among traditional livestock species, poultry are the most efficient feed converters, with a feed conversion ratio in the range of 1.6–2.0. The main ...

The importance of the microbiota in the gastrointestinal tract of animals is recognized to have an important role in host health and productivity. In this study, we sought to assess and characterize the microbiota in the feces of poultry chickens from several farms of 2 different integrators in the same geographical region of South America. These companies were changing AGP program to an AGP-free ...
