Application of the Chromic Oxide Indicator Method to Balance Studies with Growing Chickens

Alimentary Canal: Anatomy, Regulation of Feeding, and Motility

“…Radiography may also be used, and via this technique, the rate of passage from the mouth through specific portions of the tract can be observed. In chickens and turkeys, markers first appear in the excreta within about 2-2.5 hr, and most of the marker from a marked meal can be recovered within 24 hr (Dansky and Hill, 1952;Tuckey et al, 1958); however, a marker can be detected in the cecal excreta of turkeys for up to 72 hrs after feeding (Duke et al, 1968). Using radioactive barium, Imabayashi et al (1956) found that about half of the label was excreted from chickens within 4-5 hr.…”

A Survey of Recent Advances in Poultry Physiology

“…However, I should like to point out some of the newer techniques which may accelerate work in this field. Several workers have reported on the use of chromic oxide as a marker for use in studies on rate of passage of food through the alimentary tract, and balance and digestion studies of birds (Dansky and Hill, 1952;and Mueller, 1956). Also new surgical techniques on the separation and exteriorizing of the anus and ureters of birds, which represent marked improvements over older techniques, have been reported by Imabayashi, Kametaka and Hatano (1956) and Dixon and Wilkinson (1957).…”
