USPOULTRY announces the completion of a funded research project at the University of Arkansas in Fayetteville, Arkansas, that shows the nutritional effects of coccidiosis vaccination. The research was made possible in part by an endowing Foundation gift from Simmons Foods and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A summary of the completed project is shown below. A complete report may be obtained by going to USPOULTRY’s website, The project summary is as follows.

Project #700: Optimizing Amino Acid Digestibility and Energy Values Used in Feed Formulations for Broilers Vaccinated for the Control of Coccidiosis
(Dr. Samuel Rochell and Dr. Juan Latorre, University of Arkansas, Fayetteville, Arkansas)


Dr. Samuel Rochell and Dr. Juan Latorre at the University of Arkansas recently completed a research project where they studied the effects on nutrient digestibility of the use of live coccidiosis vaccines in broilers. They found that the most significant effect was the decrease in digestibility of lipids in the diets. These findings indicate possible dietary changes that could enhance performance of broilers when given live coccidiosis vaccines.
