This work aimed to evaluate female lineage broilers for halothane sensitivity and for their susceptibility to the subsequent development of PSE meat. The halothane test was carried out in an anesthetic chamber with 3.0% halothane. The unconscious birds were examined for leg muscle rigidity. If one or both legs became extended and rigid, the birds were classified as halothane sensitive (HAL+), while unresponsive birds were classified as halothane negative (HAL-). The results showed that of 298 birds aged 42 days old, 95.6% were HAL- and 4.4% were HAL+. A sample of pectoralis major muscle was collected from HAL- (n=105) and HAL+ (n=13) birds. The pH and breast fillet color were determined at 4ºC, 24 hours post-mortem. Interestingly, only 2.5% of HAL+ birds displayed PSE meat characteristics compared to 12.7% of HAL- individuals. The halothane test demonstrated that female lineage broilers displayed very little sensitivity towards halothane, indicating that the development of PSE meat is related to other environmental factors.

The pectoralis major is a widely used muscle in reconstruction surgery for replacement soft tissue defects of a head, neck, thorax, upper limbs and restoration of muscle active function. The peculiarities of anatomy of the pectoralis major makes it possible to divide the muscle into several segments with their own innervations and supply and use them independently from each other. This article describes the anatomy of the pectoralis major and the opportunity for clinical applications of different segments of this muscle. The authors demonstrate the result of the restoration of shoulder and elbow flexion in a patient with arthrogryposis due to simultaneous transfer of the proximal part of pectoralis major to the anterior part of the deltoid muscle and the distal part of pectoralis major to the biceps with good functional results. The article will be useful for plastic surgeons, orthopedic surgeons and physiotherapists.
