Effect of Type of Hay and Concentrate Level in Intake and Digestibility in Diets for Goats

The aim of this study was to evaluate the effect of the level of hay and concentrate on total hay intake and supplied already, the additive/substitutive effect and total apparent digestibility of the diet intake in diets for goats. Experiment I: diets: Alfalfa hay (A1), Alfalfa hay + corn (0.5% LW/day) (A2), + 1% LW/day (A3), + 1.5% LW/day (A4). Experiment II: diets: Natural grassland hay (CN) (R1), hay CN + corn (0.5% LW/day) (R2), hay CN + corn (1% of LW/day) (R3), + 1.5% of LW/day) (R4). Intake, ratio forage/concentrate and total apparent digestibility were calculated. Experiment I: There were no effects (p> 0.05) on the CMST for the corn tested levels and recorded a linear decrease (p 0.05) on the CMSF, CTFDN and CTFDA is observed. The F/C and CTPB differ (p <0.05) among all the diets tested. The DTAIVMS increases linearly (p
