This study aimed to estimate genetic and phenotypic parameters for foaling interval (FI), age at first foaling (AFF), generation interval (GI), reproductive life (RL) and foaling date distribution in equines of four genetic groups: Brazilian Showjumper (BS), Thoroughbred (Th), Hanoverian (HAN) and No Defined Breed (NDB). Data collected from 1977 to 2002 was provided by a Brazilian Army herd. Models used for analyses included the fixed effects of month and year of foaling and measuring, age of dam, foal sex […]
Keywords: age at first foaling; foaling interval; genetic correlations; heritability
