Assessing the effects of a mixed spp. challenge on performance, intestinal integrity, and the gut microbiome of broiler chickens.

A mixed spp. challenge model was designed to assess the effects of challenge on broiler chicken performance, intestinal integrity, and the gut microbiome for future use to evaluate alternative strategies for controlling coccidiosis in broiler chickens. The experimental design involved broiler chickens divided into two groups: a control group (uninfected) and a positive control group, infected with (EA), (EM), and (ET).

and evaluation of chlorhexidine salts as potential alternatives to potassium dichromate for M6 oocyst preservation.

Introduction: Coccidiosis caused by the spp., an Apicomplexan protozoon, is a major intestinal disease that affects the poultry industry. Although most cases of coccidiosis are subclinical, infections impair bird health and decrease overall performance, which can result in compromised welfare and major economic losses.

Experimental Cyclic Heat Stress on Intestinal Permeability, Bone Mineralization, Leukocyte Proportions and Meat Quality in Broiler Chickens.

The goal of this research was to assess cyclic heat stress on gut permeability, bone mineralization, and meat quality in chickens. Two separate trials were directed. 320 day-of-hatch Cobb 500 male chicks were randomly assigned to four thermoneutral (TN) and four cyclic heat stress (HS) chambers with two pens each, providing eight replicates per treatment in each trial (n = 20 chicks/replicate).

Assessment of Essential Oils in a and Challenge Model to Induce Necrotic Enteritis in Broiler Chickens.

The objective of the present research was to evaluate dietary supplementation of essential oils from (LEO) on necrotic enteritis (NE). Chickens were randomly assigned to three groups. Group 1: negative control; Group 2: positive control challenged with (day 1), (day 18), and (CP, days 22-23); Group 3: dietary supplementation LEO and challenged.

Evaluation of Three Formulations of Essential Oils in Broiler Chickens under Cyclic Heat Stress.

The objective of the present research was to assess the dietary supplementation of three formulations of essential oils (EO) in chickens under heat stress (HS). Day-of-hatch Cobb 500 chicks ( = 500) were randomly distributed into four groups: 1. HS control + control diets; 2.
