Abstract

A trial to verify the most adequate level of ramie in the diet of lactating goats was performed. Eight crossbred anglonubian x alpine goats at the same lactating stage were used, in a 4x4 latin square design, testing the substitution of the elephant-grass cv. Guaçu, with levels of 0,34,66 and 100% in terms of the dry matter (DM) of the roughage. the higher use of ramie in the diet, the lower the liveweight gain (P< 0.01). The milk yield followed a quadratic regression equation (P< 0.05) begining with 13.56kg (without ramie) increasing up to 15.59 kg/period, at the level of 57% of ramie in the roughage. The same kind of response (P< 0.01) was observed for CP intake. The maximum level of DM intake occured with 84% and for CF with only 25% of ramie in the roughage. The level of crude energy intake did not vary significantly (P= 0.0513) but followed the same shape observed for CP. Fat, CP and milk total solids, as well as pH and N-NH4 in ruminal liquid were not influenced (P> 0.05) by ramie levels. The diet with 66% of ramie resulted in an increase of 14.9% in milk production in relation to treatment control.
