This research was developed to estimate the energy values (TDN) of feeds, concentrate and roughage, through equations proposed by NRC (2001) and validate from the comparison among TDN values estimated by these equations and those observed in the total collection feces. Five concentrate feeds (wheat bran, soybean meal, corn ground, whole soybean and whole cotton seed) an five roughage feeds (brachiaria hay, corn silage, tifton haylage, elephant grass silage and elephantgrass) were evaluated by using 20 crossbred Holstein x Zebu […]
