Comparative use of four different marker systems for the estimation of digestibility and low food intake in a group of captive giraffes (Giraffa camelopardalis)
Abstract 10.1002/zoo.1031.abs In a feeding trial with four captive giraffes, nutrient digestibility was determined using four different marker systems. Although cobalt-ethylenediaminetetraacetic acid proved to have no utility as a digestibility marker in this study, reasonable values could be obtained using C36 n-alkane, acid detergent lignin, and acid insoluble ash as markers. A comparison of methods […]
The use of dosed and herbage n-alkanes as markers for the determination of digestive strategies of captive giraffes (Giraffa camelopardalis)
Abstract 10.1002/(SICI)1098-2361(1998)17:43.3.CO;2-0 Selected aspects of digestion in captive giraffes were investigated in two trials with a type of marker that is new for digestive studies in non-domestic species. N-Alkanes were used as internal and external markers. In Trial 1, diet composition, intake, and digestibility were directly measured and estimated with the marker. Six giraffes were […]
