Avaliou-se o desempenho da progênie de matrizes de corte que consumiram aflatoxinas e glucomananos esterificados como adsorvente por quatro ou oito semanas. Foram conduzidos dois experimentos no período de 1 a 21 dias de idade. Em cada estudo foram utilizados 160 machos de 1 dia provenientes de matrizes alimentadas com dietas contendo aflatoxinas e adsorvente. Em ambos os ensaios, foi adotado um delineamento experimental inteiramente casualizado para avaliação de cinco dietas (tratamentos), cada uma avaliada com quatro repetições de oito […]
