摘要

The intake of the ration (CR), dry matter (CMS), metabolizable energy (CEM), ether extract (CEE), crude protein (CPB), neutral detergent fibre (CFDN), acid detergent fibre (CFDA), organic matter (CMO), and also total weight gain (GPT), diary weight gain (GPD), feed conversion (CA) and feed efficiency (EA), were determinates to evaluate the effect of the inclusion of elephant-grass hay (FCE) in complete rations. Twenty seven goats of breed Saanen were used (15 males no castrated and 12 females) in the phase of growing phase, with 118 days of age and medium alive weight of 15.35 kg, fed with diets containing 30, 45 and 60% of inclusion of elephant-grass hay, distributed in entirely randomized design in factorial scheme 3×2 (three treatments and two sexes), being five males and four females for treatment. For CEM and CEE, there was a decreasing lineal effect with the increase in the levels of inclusion of FCE. Though, for CFDN and CFDA the behaviour was increase linearly. GPT presented significant effect for the effect sex (P<.01). It was verified that as the fibre levels went increasing, GPT went decreasing. The inclusion of hay of Grass-elephant in diets for goats in the growing phase, it didn't influence the intake of dry matter for the males. The level of inclusion of hay of Grass-elephant of 60% provided a better relationship cost/benefice for the males in growing phase, while for the females the level of 45% would be the most suitable.
