Determination of the Gastrointestinal Passage Rate Using Dexa Technology and Barium Sulfate As a Marker in Japanese Quails

The objective of this study was to characterize the dynamics food passage in gastrointestinal tract (GIT) Japanese quail. A randomized design used with four treatments and experimental units one bird each, nine which were measured time. ingredients albumin, starch, cellulose, soybean oil. Suspensions containing barium sulfate saline prepared, except for For each bird, 2.5 mL suspension administered directly crop. Dual-energy absorptiometry (DEXA) quantify food. birds sedated maintained under inhalation anesthesia during scan. Measurements taken at intervals 0.5, 1, 2, 4, 6, 8, 10, 12, 24 h. variables identified time, first quality, average time variable. Based on these results, may show differences dynamic passing quail GIT. duration attempt 32 min, ranging from 21 44 min. value choice close 10.8 h varied according ingredient 8.45-12.16 Among variables, oil presented values ​​that denote a fast GIT, while albumin slower passage. GIT quails varies chemical composition ingredients.
