“…Considering the Holstein breed in Brazil, heritability estimates for the test-day milk yield, adjusted with the Legendre polynomials, Wilmink, Ali & Schaeffer under RRM range from .11 to .31 (Cobuci et al, 2004;Cobuci et al, 2006;Araújo et al, 2006;Costa et al, 2008;Biassus, Cobuci, & Costa, 2011). These results are in agreement with heritability results observed in studies with Holsteins from other countries, ranging from 0.08 to 0.23 (Hahammi et al, 2008;Silvestre, Petim-Batista, & Colaço, 2006;Strabel & Misztal, 1999).…”
