The Potential of Guanidino Acetic Acid to Reduce the Occurrence and Severity of Broiler Muscle Myopathies
Published: July 14, 2021
Summary
INTRODUCTION Genetic selection in poultry has progressed continuously since the early 1960s, resulting in faster growth rates and higher meat production (Havenstein et al., 2003a,b). Over the past 60 years, body weight gain has increased fourfold from 1957 to 2005 with a simultaneous 50% reduction in feed conversion ratio and 79% higher Pectoralis major yield in males and 85% in females (...

Thank you so much Edgar Orlando Oviedo-Rondón and Hernan Alejandro Córdova-Noboa for this comprehensive article, which clearly shows the mode of action of guanidinoacetic acid in mitigating wooden breast incidence and severity.
Interestingly, it was found that the percentage reduction of breast muscle creatine was 17% in wooden breast affected muscle and 4% in white stripping compared to normal pectoral muscle. In addition, the percentage reduction of glycogen in the muscles affected by wooden breast was 31%, and 26% lower in muscles affected by white stripping than in normal meat. It is worth noting that GAA supplementation not only increase breast muscle creatine but also maintains the glycogen content in pectoral muscle, which underline the importance of the energy buffering system of creatine-phosphocreatine and its association with breast muscle glycogen, which regulates the glycolytic pathway of breast muscle and reduce muscle damage (Khalil et al., 2021).
