Extract

Cooperia punctata is the most prevalent intestinal parasite in young bovines in Brazil (Lima, 1998). The site of fixation of C. punctata is the upper part of the small intestine (Bailey, 1949), also the site of dietary phosphorus (P) absorption (Schröder et al, 1995), and the damage caused in the intestinal epithelium could interfere with P metabolism (Bown et al, 1989). The aim of the present experiment was to evaluate the P kinetics by using 32P isotopic dilution technique in calves submitted to single and trickle infection by C. punctata.
