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.

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.
