Measuring Digestibility
نویسندگان
چکیده
As the aquaculture industry becomes increasingly conscious of costs and benefits, it is searching for more “functional” feeds, many of which are augmented with key ingredients and compounds that promote animal growth and survival. In addition, plant proteins are increasingly used as alternatives to proteins from animal sources. The optimum production of feedstuffs with optimum dry matter conversion of feed to weight depends largely on ingredient quality and nutrient availability for the species in question. The determination of digestibility of major nutrients is one of the main steps in the evaluation of their bioavailability for a given species.

The use of chromic oxide as a marker for measuring small intestinal digestibility in cannulated dogs.
Small intestinal digestibility can be measured by comparing feed with effluent collected from an ileal T-cannula. Nevertheless, a nondigestible, nonabsorbable marker, such as chromic oxide (Cr2O3), must be included in the diet because simple T-cannulae do not divert chyme completely. This study was conducted to evaluate the excretion pattern of Cr2O3 in cannulated dogs because the kinetics of C...
متن کاملEstimation of Total Tract Apparent Digestibility of Nutrients in Three Annual Summer Forages Using Two Different Digestibility Markers
A study was performed to: 1) compare total tract digestibility of nutrients for three annual summer forages: Mulato II (hybrid Brachiaria); “Tifleaf 3” Pearl Millet (Pennisetum glaucum); and “Hay Day” Sorghum sudan (Sorghum bicolor) and 2) determine the efficacy of two digestibility markers: titanium dioxide (TiO2) and chromic oxide (Cr2O3) used with a fecal sample collection protocol of either...
متن کاملThe apparent intestinal synthesis of carotene by sheep.
During an investigation into certain aspects of the carotene metabolism of ruminants, it was desired to obtain an indication of the effect of the composition of the feed on the availability of carotene to the animals. The most convenient method of measuring approximately the carotene absorption appeared to be by determining its apparent digestibility using the ordinary digestibility-trial techn...
متن کاملInterpretation of Forage Analysis Reports
Forage analyses are a valuable tool for determining the economic value of forages and for formulating efficient and profitable rations. To be useful, forage analyses must be determined accurately and interpreted correctly. The sample submitted must truly represent the feed being analyzed and the forage analyses must provide information that is relevant. There are reliable and repeatable methods...
متن کاملDigestible Amino Acids: Determination and Use
For a dietary amino acid to be retained in tissue protein in an animal, the amino acid needs to be ingested by the animal and absorbed from the intestinal tract. While the absorption of amino acids is a concept that can easily be defined, it is difficult to measure. Instead, the digestibility of amino acids is measured. Digestibility is defined as the difference between the amount of a certain ...
