The purpose of the present experiments was to compare the effects of the intermittent lighting schedule (IL) consisting of repeated cycles of 1 h light (L):3 h darkness (D) with a nearly continuous lighting schedule 23L:1D (CL) on the performance of floor-reared male and female broiler chickens. In addition, N balance trials were performed on caged broilers in order to assess their efficiency o...

We describe a rare case of massive deep diving cervical ranula involving multiple tissue spaces and extending to the upper mediastinum. The unusual course of events following surgical excision of the submandibular gland is presented. A Computerized Tomography (CT) scan revealed t...
