PEREIRA, E.S. et al. Energetic value from by-product of the brazil agroindustria. Arch. zootec. [online]. 2009, vol.58, n.223, pp.455-458. ISSN 1885-4494.

It was evaluated the carbohydrate and protein fractions of cashew, passion fruit, melon, Bixa orellana, pineapple and acerola by-products; it was estimated and valided the energy value of the feeds from the NRC (2001). The carbohydrate and protein fractions and TDN values changed substantially between by-products. It was concluded that the analysis of the carbohydrate and protein fractions of by-products must be laboratory routine. The observed and predict TDN values of the feeds by NRC (2001) equations were similar, being appropriate for estimating the energy value of the feeds.

Palabras clave : Cashew; Passion fruit; Melon; Bixa orellana; Pineapple; Acerola.
