Chromic oxide was used as inert marker and incorporated into diets @1% of the feed to determine digestibility of ingredients (Hussain et al., 2011).
Fecal excretion was estimated using chromic oxide (Burns, Pond, & Fisher, 1994), calculated based on the ratio of the amount of indicator supplied and its concentration in faeces:
At the end of the trial, all feces were freeze-dried for a complete chemical analysis to determine the apparent digestibility coefficient, measuring the concentration of chromic oxide following Furukawa & Tsukahara (1966) modified by Olvera-Novoa & Olivera-Castillo (1999) as follow: ADC dry matter (%) = 100 - [([Cr.sub.2][O.sub.3] in feed / %[Cr.sub.2][O.sub.3] in feces) x 100]; ADC nutrients (%) = 100-100[(%[Cr.sub.2][O.sub.3] in feed / %[Cr.sub.2][O.sub.3] in feces) x (% nutrient in feces / % nutrient in feed)].
Chromic oxide and acid-insoluble ash as faecal markers in digestibility studies with young growing pigs.
Apparent digestibility of nutrients (%) = 100 - 100 x [percent chromic oxide in diet x percent nutrient in feces / percent chromic oxide in feces x percent nutrient in diet].
In other words, in the presence of NaCl (Figure 9), Cr is lost from the surface as volatile chromic chloride and the oxidation rate to replace the normal chromic oxide film will increase [8].

ADCs for energy were measured indirectly using 0.1% of chromic oxide (Cr2O3) as an inert marker.

Chromium (VI) is used and/or released in the occupational setting of a number of major industries, especially chrome ore smelting, electroplating and chromic oxide and tanning salts production.
