Immunofluorescence microscopy in this study shows that GLUT-4 protein expression is fibre-type specific within a muscle. It is postulated that both fibre-type-dependent and fibre-type-independent factors affect GLUT-4 expression.

Improving estrus detection accuracy could improve sow conception rates,leading to higher production efficiency. Current observation-based estrusdetection practices are labor intensive and less accurate. Around estrus, bodytemperature and activity change. Therefore in this study a telemetric monitoringsystem …
