Nutritional value of goat diets was determined in the State of Puebla, Southern Mexico in a tropical semi-deciduos forest during the fall months (September-December), using esophageally fistulated goats, grazing under herding conditions, along with a band of intact goats. Goats were also divided in three groups to evaluate the nutritional contribution and effects of two feed supplements. A third group served as a control without access to any kind of feed supplement (T3). The composition of feed supplements was as follows: Supplement T1) Sugar cane 71 percent, polished rice groats 15 percent, molasses 13.7 percent and urea 0.3 percent. Supplement T2) Same ingredients, but only sugar cane plant tops (71 percent). Fistula samples were analyzed using conventional analytical procedures with the following results: CP (percent) 13.9, 13.6 and 14.2; DE (Mcal/kg) 2.3, 2.4 and 2.3; ME (Mcal/kg) 1.9, 2.0 and 1.9; NDF (percent) 43.1, 45.5 and 46.6; ADF (percent) 33.4, 37.8 and 35.2; OMIVD (percent) 52.6, 51.0 and 50.8. Through total fecal collection, daily intake was also estimated, determining rumen fermentation patterns, using rumen fistulated goats in order to evaluate the effects of sugar cane supplementation. Organic matter daily intake was 7.4 g/kg of live weight; 8.4 g/kg of live weight and 7.0 g/kg of live weight for the goats consuming Supplement A, Supplement B and without supplement, respectively. Regarding the rumen, concentration of fatty acids, no significant differences were detected between the supplement groups of goats and control
