  The colorimetric method of Schürch and co-workers for the determination of chromium has been modified by measurement of color density at mµ.

The l h collection was intended to serve as a periodic grab sampling for camels on the range. This requires that the chromic oxide be excreted in the faeces uniformly and be completely by: 3. The chromic oxide method is suitable for digestibility and balance trials with dogs. The apparent digestibility of crude protein and ether extract was greater in 4 dogs aged 8 years or more than in 4 aged 7 months.-D. by: Results of a balance study in which chromic oxide and crude fibre were used in diets for laying hens are presented; there was good agreement between the 2 markers. Feed and droppings from turkey poults kept in batteries were analysed and showed that the mean recovery of crude fibre in the droppings was % of that eaten (range to %).

McGinnis, A. J., and Kastin R., b, Comparison of gravimetric and chromic oxide methods for measuring percentage utilization and consumption of food by phytophagous insects, J. Insect Physiol. – CrossRef Google Scholar.   1. Introduction. Chromic oxide is the most commonly used external digestibility marker in site and extent of digestion trials with ruminants. Titgemeyer () reported that 90 of flow studies published in the J. Anim. Sci. between and used Cr 2 O 3 as their digestibility marker. However, there are several problems associated with Cr 2 O 3, including concerns over potential.   Indigestible markers are commonly used in animal nutrition studies to calculate digestibility coefficients, with chromic oxide, titanium dioxide, and acid insoluble ash being the most common in swine research [].Physiological aspects associated with gastric emptying or rate of passage are complex and affected by a variety of factors [2, 3].Rate of passage can be affected by BW [], feed . The effectiveness of the external marker yttrium oxide (Y 2 O 3) and sampling period for determining the apparent digestibility (AD) of minerals and trace elements within Atlantic salmon feeds were m oxide was compared at inclusions of , , 1 and 10 g kg −1 wet weight of the feeds. Samples were analysed for a range of mineral and trace elements via inductively coupled.

Fecal output of dry cows was measured with total fecal collections and was also estimated with the chromic oxide dilution technique. in range nutrition studies of cattle ranges from to. A series of experiments was designed to evaluate inert markers employed in studies of ileal and faecal apparent digestibilities of nitrogen and amino acids in pigs fitted with simple ‘T’ piece cannulas. Trial 1 assessed the palatability of diets containing (a) 5 g chromic oxide/kg, (b) 1 and (c) 5.   Chromic oxide is used as an inert marker to measure apparent digestibility of feeds in insects, terrestrial, and aquatic animals. Quantitative determination of chromic oxide content in the sample requires the oxidation of water insoluble trivalent chromic oxide to its water-soluble hexavalent form. The two commonly used oxidizing agents are 70% perchloric acid or a mixture of sodium . Studies on intestinal digestion in the sheep - Volume 23 Issue 1 - J. C MacRae, D. G.
