Abstract
Avaliaram-se os efeitos dos níveis de ácido linoléico na dieta de matrizes pesadas, de 27 a 40 semanas de idade, sobre o peso e composição dos ovos, porcentagem de eclosão, peso do pinto, porcentagem de saco vitelino em relação ao peso do pinto e composição de ácidos graxos da gema. Os tratamentos foram definidos pelo nível de ácido linoléico na dieta. O peso dos ovos e a composição de ácidos linoléico na gema foram mais altos com a inclusão de 1,93% de ácido linoléico que a de 1,48% (59,5g vs 59,0g e 19,5% vs 15,5%, respectivamente). Não houve diferença entre os tratamentos quanto às porcentagens de gema, albúmen, casca, saco vitelino, eclosão e peso do pinto.Keywords
