Morphological changes of the intestinal mucosa of broilers and layers as affected by fasting before sample collection
The present study aimed at evaluating the histo-morphological changes resulting from different fasting periods before the collection of tissue samples in different segments of the small intestine (duodenum, jejunum and ileum) of 7-d-old male chicks of a broiler and a layer strain. A completely rando...
