The objectives of this paper were estimate the energy values of feeds through equations proposed by NRC, from feed composition present in data base of “Brazilian Tables of Feed Composition for Cattle” and of a trial that used sheep, and validate those equations from observed values of TDN, digestible fractions of NDF (DNDF), crude protein (DCP), ether extract (DEE) and nonfiber carbohydrates (DNFC), that were obtained on Brazilian Scientific literature through in vivo experiments at maintenance level. The procedure to […]
