Huizache (Acacia farnesiana (L.) Willd. ) is a wild species commonly distributed in Jalisco and other states of Mexico, which may be used as forage. A study was performed on the fruit of huizache (husk and seed) in both, untreated samples and samples with pre-extraction of tannin, for the determi nation of chemical proximal analysis (QPA ), aminoacid profile, and in situ degradability, in fistulated pelibuey sheep specimens. Tannins were evaluated using the ALCA method and the Stiasny number technique. QPA analysis showed high protein content in raw seeds of 23,0%, higher than husk content
