Methodische Untersuchungen zur ilealen Flußmessung mittels großlumiger Darmkanülen beim Schwein

Abstract

A special operation method and intestinal cannulae were developed for the ascertainment of the ileal nutrient digestibility of roughage and root crops. The presented method has proved reliable over a period of 2 years. The possibility of ascertaining the chyme flow directly (by total collection) or indirectly (with an inert marker) is described. The reduction of the expenditure of labour by cutting down the collecting period is suggested for routine studies.

Technical note: a technique for inserting a T-cannula into the distal ileum of pregnant sows.

“…Surgical procedures for inserting a T-cannula into the distal ileum of young pigs (Walker et al, 1986;Li et al, 1993) and growing pigs (Furuya et al, 1974;Decuypere et al, 1977;Gargallo and Zimmermann, 1980;Kesting et al, 1986) have been described. Likewise, ileal cannulation of nonpregnant, breedingage gilts has been reported (Hamilton et al, 1985;Mroz and Tarkowski, 1991).…”
