Cyclic Watering of Broiler Cockerels

Growth Performance and Carcass Quality of Layer Type Cockerels and Broiler Chicken

The aim of the study was to compare the growth performance and carcass quality of layer-type cockerels and broilers reared under identical conditions. A total of 180 one-day-old broiler male (BM), broiler female (BF) and brown layer male (LM) chicks were distributed into 9 floor pens in a completely randomized design, with 3 replicates of 20 birds per experimental unit. The body weights and fee...

Diet-induced thermogenesis and feed intake in poultry: broiler versus layer cockerels

Research with adult mammals has shown that the diet-induced thermogenesis (DIT) related to the oxidation of macronutrients has a negative feedback on feed intake (FI), depending on the nutrient considered: proteins are combusted first, then carbohydrates and finally fat, corresponding to their satiating ability. However, previous studies revealed no significant differences in DIT between broile...

Watering CanMEDS flowers

We expand on the discourse related to nature surrounding Canadian medical training and the CanMEDS flower. We advance the notion that a major contributor to burnout is the increasing complexity and segregation of not only the medical profession, but society as a whole, leading to choice overload and an overemphasis on complex, data driven, rational decision making. We then propose that the key ...

Glutamate ionotropic and metabotropic receptors affect feed intake in broiler cockerels

The role of 5-HT2A and 5-HT2C receptors on harmalineinduced eating behavior in 24-h food-deprived broiler cockerels

This study was designed to examine the effects of intracerebroventricular (ICV) injection of ketanserin(5-HT2a receptor antagonist) and SB242084 (5-HT2c receptor antagonist) on harmaline induced feeding anddrinking response in 24-h food-deprived (FD24) broiler cockerels. At first, guide cannula was surgicallyimplanted in the right lateral ventricle of chickens. In experiment 1, birds were injec...
