Abstract

Twenty four lambs were employed to evaluate digestibility of diets with sugar cane as the only roughage. in a factorial 2 x 3 disposition of treatments : sugar cane in natura or as silage, with 0.0%, 0.5% and 1.0% of urea. It was adopted a completely randonmized design, and digestion trial runned in metabolic cages. After a pre-experimental period of 21 days , faeces, feed and refuged were collected for 5 consecutive days, to analize dry matter, crude protein, crude fiber, non nitrogen extratives, eter extract, and neutral detergent fiber. Results of digestibility were better for sugar cane €œin natura€ than for silage, with especifically higher digestion coefficents (p<0.01) for dry matter and non nitrogen extractives . Crescent urea levels also showed higher dry matter and non nitrogen extractives digestibility results (p<0.05) when apllyed to sugar cane in natura than to sugar cane silage.
