Abstract

Muscle alterations in broiler breast meat as Wooden Breast and White Striping have been investigated in different areas of expertise to find out the etiology or to decrease the incidence. Research involving additives supplementation and nutritional strategies showed a possible decrease in incidence, but it is important to note the consequences in broiler performance. Estimated heritability for White Striping defect was low to moderate, considering different ways to analyze the breast alterations scores and statistical methodologies. In Brazil, until 2019, carcass affected by Wooden Breast was condemned in the slaughterhouse, especially extreme severe degree. A recent decree published by governmental institution oriented to stop condemnation and oriented the destination of these meat, depending on severity degree of muscle alteration. This regulation is important to reduce the economic losses by poultry industries however, the occurrence of muscle defects will not stop. The measurement of the impact on processing and performance industries is still understood and need to be monitored by poultry companies. More studies about the impact of breast myopathies on economic losses considering this new scenario need to be available.

Keywords: Broiler, condemnation, white striping and wooden breast.
