Los datos sobre la composicion de alimentos, se obtuvieron de la libreria tropical del CNCPS [52] y de tablas de composicion de alimentos del NRC [44] para valores de total de nutrimentos digestibles (TND), fibra detergente neutro (FDN) y fibra detergente neutro efectiva (FDNe), de los ingredientes que no se encontraron en la primera fuente.

Subsequently, the protein fractionation was calculated for the five fractions (A, B1, B2, B3, and C) by the CNCPS system (SNIFFEN et al.
O CNCPS considera digestibilidades verdadeiras de 100, 100, 80 e 0% para as fracoes nitrogenadas [B.
There are two systems of protein pools currently in use in dairy nutrition: the dairy NRC system and the CNCPS 4.
Many trials indicated that the CNCPS fractions closely correlated with some indices of rumen fermentation, including the duodenal flow of microbial N (Offner and Sauvant, 2004) and the in situ undegraded dietary protein (UDP) for ruminants (Shannak et al.

The estimates of weight gain as a function of metabolizable energy intake, calculated (crossbred males with 340 kg BW) according to the CNCPS (2003), were similar to the observed weight gains (Tables 4 and 5).
