Extract

Lactodynamographic analysis is commonly employed to evaluate the clotting aptitude of milk (Frentz, 1965; Tarodo de la Fuente et al. 1969). The individual lactodynamographic response can therefore be used in selection as a quantitative trait. The aim of this work was to estimate either the biological repeatability of the lactodynamographic response or the repeatability of the analytical method itself.
