Development and Evaluation of a Commercial Direct-Fed Microbial (Zymospore) on the Fecal Microbiome and Growth Performance of Broiler Chickens under Experimental Challenge Conditions.

Direct-fed microbials (DFM) are added to broiler chicken diets in order to promote the proliferation of beneficial intestinal bacterial populations, which may lead to gains in performance efficiency and, potentially, reduce the level of enteric pathogens in the broiler chickens. The selection and laboratory evaluation of strains as well as the experimental trial results of a novel -based commercial DFM product are described. Fifteen wild-type strains were characterized and assayed for their enzyme production capability, spore resistance to pH, salinity, and temperature, and ability to inhibit the growth of and spp.

Laying hens fed mycotoxin-contaminated feed produced by Fusarium fungi (T-2 toxin and fumonisin B1) and Saccharomyces cerevisiae lysate: Impacts on poultry health, productive efficiency, and egg quality.

Mycotoxins represent substantial challenges to the farming industry. These include toxins produced by Fusarium fungi, particularly trichothecenes (toxin T-2) and fumonisin (FB). In the present study, we determined the effects of addition on Saccharomyces cerevisiae lysate (SCL) added to feed contaminated with T-2 and FB in terms of health, productive efficiency, and egg laying quality.

Correlation between intestinal health and coccidiosis prevalence in broilers in Brazilian agroindustries.

Coccidiosis is caused by protozoa of the genus Eimeria. These are intracellular parasites of enterocytes that rupture the host cell, causing lesions in the intestinal mucosa. The lesions caused by Eimeria reduce nutrient absorption capacity, negatively affecting productive gains in broilers, and representing a gateway for other enteropathogens.
