Effects of High Rice Diet on Growth Performance, Nutrients Apparent Digestibility, Nitrogen Metabolism, Blood Parameters and Rumen Fermentation in Growing Goats

This study was conducted to evaluate the effects of high rice grain diet on apparent nutrient digestibility, growth performance, nitrogen digestion, blood parameters and rumen fermentation in goats. Sixteen growing goats were divided into 2 groups and fed a normalconcentrate diet (NC, 55% concentrate of dry matter; n=8) or a high concentrate diet (HC, 90% concentrate of dry matter; n=8) for 5 wk. Growth performance, nutrients digestibility, nitrogen digestion, blood parameters and ruminal fermentation were measured. Total weight gain and average daily gain increased in the HC group (P
