Effects of hay inclusion on intake, in vivo nutrient utilization and ruminal fermentation of goats fed spineless cactus ( Opuntia fícus-indica Mill) based diets

A study was conducted to determine the minimum level of tifton bermudagrass hay (TH) required to maximize cactus intake by buck goats without compromising nutrient utilization or ruminal fermentation. Five ruminally fistulated goats were used in a 5 × 5 Latin square experiment with 17-day periods. E...

Description
Summary:A study was conducted to determine the minimum level of tifton bermudagrass hay (TH) required to maximize cactus intake by buck goats without compromising nutrient utilization or ruminal fermentation. Five ruminally fistulated goats were used in a 5 × 5 Latin square experiment with 17-day periods. Experimental diets contained (g/kg dry matter (DM) basis) 765, 670, 572, 473 and 373 spineless cactus and 50, 150 250, 350, and 450 TH, respectively. Intake of DM increased quadratically (P
