Body condition scores (BCS) and/or body weights (BWT) are often used as visual or tactile management tools to evaluate and improve reproductive competency in pasture-managed small ruminant animals. This study was designed relationships between BCS, BWT traits (number born alive weaned, litter size, birth weaning weights) 16 purebred Kiko, 11 Boer 7 Kiko x crossbred meat goat dams that were semi...
