Aggressive behaviour traits predict physiological stress responses in Nile tilapia (Oreochromis niloticus)
This study tested whether aggressive behaviour can predict individual variation in stress responses of Nile tilapia Oreochromis niloticus.We used a mirror test to measure tendency to aggressive behaviour, and calculated the attack frequency and time until the first attack (latency) for each fish. One day later, we measured plasma cortisol and glucose, and two days […]
Effects of Dietary Physical Form and Carbohydrate Profile on Captive Giraffe
The effects of altering physical form and carbohydrate profile of giraffe diets were evaluated using six non-lactating adult female giraffe in a modified reversal study. Dietary treatments consisted of a supplement ration composed of commonly fed commercial concentrates (GF) and an experimental supplement (EF) containing greater concentrations of sugars and soluble fiber and lesser concentrations […]
