Abstract Twelve crossberd rams (Ovis aries L ), 17 months old, were assigned to a completely randomized digestion trial with two treatments to evaluate apparent digestibility of cunhâ hay (Clitoria ternatea L.) harvested at two different stages: A) 60 days and B) 90 days of maturity. Digestibility coefficients of dry matter, crude fiber and ether extract, as well total digestible nutrients (TDN), were higher for the hay harvested at 90 days. However, digestibility of nitrogen free extract was better for the 60-day hay, whereas crude protein digestibility did not differ between treatments. It was concluded that Cunhâ can be harvested at 90 days of growth. Foram utilizados doze ovinos mestiços, machos inteiros, com idade média de 17 meses, em ensaio de digestibilidade aparente, segundo delineamento inteiramente casualizado, com dois tratamentos para avaliar-se o feno de Cunhã (Clitoria ternatea L.) cortados com A) 60 dias B) 90 dias de idade vegetativa. Os resultados deste ensaio permitiram concluir que os coeficientes de digestibilidade da matéria seca, fibra bruta, extrato etéreo e o teor de N.D.T. (nutrientes digestíveis totais) foram mais elevados para o feno cortado aos 90 dias, porém a digestibilidade dos extrativos não nitrogenados foi melhor para o feno de 60 dias, enquanto que a digestibilidade da proteína foi semelhante para os dois fenos. Concluiu-se que a Cunhã cortada aos 90 dias de crescimento continua a fornecer feno de boa qualidade.
