Fiber digestibility and nitrogen requirements of blue duikers (Cephalophus monticola)
Abstract 10.1002/zoo.10025.abs We examined the energy and protein requirements, and the fiber and protein digestive capacity, of a small African ruminant, the blue duiker (Cephalophus monticola), by conducting a series of complete balance digestion trials with three captive male blue duikers feeding on fruits, leaves, forbs, grass, and pelleted diets ranging from 9.4% to 49% […]
Nitrogen requirements of white-lipped peccary (Mammalia, Tayassuidae)
A study was conducted to determine the protein requirement of the white-lipped peccary (Tayassu pecari) performing a nitrogen (N) balance digestion trial. In a 4 × 4 Latin square design, four adult captive male peccaries were fed four isoenergetic diets containing four different levels of N (13.3, 19.2, 28.7, and 37.1 g N/kg dry matter). After 15 days of […]
Effect of concentrates restriction on feed consumption, diet digestibility, and nitrogen utilization in captive Asian elephants (Elephas maximus)
In order to study the effect of concentrates restriction on feed consumption, diet digestibility, and utilization of nitrogen in captive Asian elephants (Elephas maximus), two feeding trials were conducted on three juveniles, four sub-adults, and three adults. During trial I, the conventional zoo diets of juveniles, sub-adults, and adult contained 22, 17, and 16% of […]
