[HTML][HTML] The accuracy of seven mathematical functions in modeling dairy cattle lactation curves based on test-day records from varying sample schemes
AM Silvestre, F Petim-Batista, J Colaço - Journal of dairy science, 2006 - Elsevier
Daily milk yield over the course of the lactation follows a curvilinear pattern, so a suitable
function is required to model this curve. In this study, 7 functions (Wood, Wilmink, Ali and …
