April 24, 2017, Tucker, GA – The U.S. Poultry Foundation announced the completion of a funded research project at the University of Delaware in Newark, Delaware, in which researchers report a potential cause of wooden breast lesion in broilers. The “woody breast” condition has long confused producers and processors, and research has been ongoing to find an explanation for the condition.

The research project is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing.

Dr. Benham Abasht and colleagues at the Univ. of Delaware found that the early lesions of the condition could be found in the breast tissue of one-week old broilers, and the first stage of the condition involves inflammation of the veins in the breast tissue and accumulation of lipid around the affected veins. The study went onto say that this condition was followed over time by muscle cell death and replacement by fibrous and fatty tissue. Genetic analyses also indicated that there was dysfunction in lipid metabolism in affected birds. This new understanding that inflammation of veins is the likely cause of wooden breast lesions in broilers will provide important direction for future research on this condition. READ MORE
