Background: Feeding behavior is regulated by a complex network which interacts via diverse signals from central and peripheral tissues. It is known dopaminergic and glutamatergic systems have crucial role on food intake regulation but scarce reports exist on their interaction in appetite regulation in broilers. OBJECTIVES: The present study was designed to examine the role of glutamatergic syst...

The effects of organic and inorganic sources and concentration (0 and 0.3 mg per kg of diet) of Selenium (Se) on growth performance, blood biochemical and immune system were evaluated in broiler chickens. Chickens were fed corn-soy-based diets formulated to 8 dietary treatments containing no added Se (negative control), negative control plus yeast (positive control), and 6 diets had 0.3 mg/kg o...

This paper describes the experimental study of a behavioural barrier consisting bubble curtain placed near an ecological river water intake, aiming to assess curtain’s influence on velocity field flowing in intake proximity. The scientific novelty is given by solution operating tandem with dedicated generator used for avoiding fish entrapment. present research based run-of-river without dam riv...
