Influence of different dietary calcium levels on the digestibility of Ca, Mg, and P in captive-born juvenile Galapagos giant tortoises (Geochelone nigra)
Abstract 10.1002/zoo.1035.abs Calcium (Ca) and phosphorus (P) are very important minerals in reptile nutrition, but many diets still are not balanced. To achieve optimal growth, including a healthy skeleton and a strong shell, a well-balanced supply with these minerals is prerequisite. The purpose of this study was to evaluate the digestibility of diets with different […]
Early growth and bone mineralization of the iguanid lizard, Sceloporus occidentalis in captivity: Is vitamin D3 supplementation or ultraviolet B irradiation necessary?
Abstract 10.1002/zoo.1430100504.abs The insectivorous, heliophilic iguanid lizard, Sceloporus occidentalis, was used in this study. Eight groups of field-collected juveniles were subjected to different doses of ultraviolet-B radiation or were fed crickets maintained on different diets with varying amounts of vitamin D3 and other nutrients. The crickets fed to all groups were dusted with calcium carbonate […]
The influence of a magnesium rich marine supplement on behaviour, salivary cortisol levels, and skin lesions in growing pigs exposed to acute stressors
Pigs in intensive production systems typically experience multiple acute stressors which can have a negative impact on their welfare. This study investigated whether a magnesium (Mg) rich marine extract (SUPPLEMENT) could reduce the negative effects of mixing and an out-of-feed event on pig welfare. At weaning (28 d) 448 piglets were assigned to either control […]
