The effect of treating nonlinted whole Pima cottonseeds (WCS) with heat, NaOH, or their
combination on digestive tract digestibility in dairy cows, was studied using the mobile dacron bag
technique. NaOH treatment increased ruminal DM disappearance from WCS. For DM there was an
interaction, between heat treatment and incubation time. Interactions of NaOH x heat and heat
x incubation time were found for ruminal CP disappearance. Heat treatment decreased ruminal CP
disappearance. With WCS which was heat-treated in the presence of NaOH, ruminal CP
disappearance decreased. NaOH and heat treatments of WCS, respectively, increased and decreased
intestinal DM disappearance. These respective treatments also increased and decreased intestinal CP
disappearance. NaOH and heat treatments of WCS, respectively, increased and decreased total tract
DM and CP disappearance. It was concluded that a combination of NaOH and heat treatments may
protect nonlinted WCS from excessive ruminal CP degradation and deliver more nutrients to the
intestine.
