Abstract: The objective of this study investigate and compare the protein fraction of scheme CNCPS and chemical composition of seeds and pulps from White Grape Pomace (WGP) and Red Grape Pomace (RGP) origin as conventional feed in ruminants. The data was analyzed by using SAS 9.1 in completely randomized design. Comparison between the general compositions of both whole GPs, reveals important significant differences in ADF (p<0.05) and protein (p<0.05) values but chemical composition had non-significant difference (NDF, EE, OM, DM) in whole GPs (p>0.01). WGP seeds had higher CP (p<0.05) and ADF (p<0.05) than RGP seeds but RGP seeds had higher NDF (p<0.01) than RGP seeds but chemical composition had non-significant difference (EE, OM, DM) in whole GPs (p<0.05). Chemical analysis of GP pulp is remarkably similar with the notable exception of a lower level of ADF (p<0.01) and CP (p<0.05) in RGP pulp which had lower than WGP pulp. Nevertheless, chemical composition had non-significant difference (EE, OM, DM) in GPs pulp (p<0.05). Protein fractions A, B2 and B3 GPs had non-significant difference (p<0.05) but WGP had B1 lower (p<0.05) and B3 higher (p<0.01) than RGP (19.70, 13.40 and 28.06, 9.77 (CP%), respectively). WGP seeds had higher (p<0.01) C than RGP seeds (19.23 and 15.14 (CP%). Although, RGP seeds had higher (p<0.01) B2 than WGP seeds (10.70 and 4.33). WGP pulp had higher C (p<0.05) and B3 (p<0.05) than RGP pulp (19.34, 19.23 and 12.07, 15.14, respectively). Results showed that high proportion protein WGP and RGP is non-available for ruminant.
