Possible use of an indicator muscle in future breeding experiments in domestic fowl

Abstract: Domestic fowl were chosen for different body weights in descending order of size, viz. Tetra, Rhode Island Red/Light Sussex cross, White Leghorn and Bantam. The numbers and sizes of fibres in various muscles were determined by quantitative histology, and fibre number was also estimated by DNA measurement. In contrast to the situation in mammals, fibre size (diameter) was of greater importance than fibre number in determining muscle size. Biochemical measurement of DNA content in a muscle was not a reliable est… Show more

“…The Silky birds had the smallest muscles and these were associated with the smallest myofiber diameter of each type. Breed differences in muscle volume are mainly determined either by myofiber numbers (Mizuno & Hikami 1971) or by myofiber size (Prentis et al . 1984; Horak et al .…”

“…Silky birds had the smallest muscle and these were associated with myofibers of the smallest diameter. Muscle volumes that differ between breeds show variation either in myofiber numbers (Mizuno & Hikami 1971) or myofiber sizes (Prentis et al . 1984; Horak et al .…”

“…In chickens, selection for overall growth has been shown to induce greater muscle weight at the same age by increasing the fiber size and number (Rémignon et al, 1995;Burke and Henry, 1997;Scheuermann et al, 2004). However, according to Prentis et al (1984), fiber size was of greater importance than fiber number in determining muscle size. Moreover, it seems that broiler selection focused on improved breast yield led to wider and thicker P. major muscles essentially by increasing the diameter and length of fiber without significantly altering their number (Guernec et al, 2003).…”
