بمصر. ABSTRACTMixed sex Japanese quail chicks (924) were reared in battery cages at the poultry production farm, Biological Applications Department, Nuclear Research Center, Atomic Energy Authority, Egypt. On day 15, they were weighed and randomly assigned into three main groups A, B and C, each of 132, 264 and 528 chicks, respectively. Each group was randomly divided into equal three cages of 1 m2 to obtain stocking densities of 44, 88 and 176 birds/m2, respectively. At 42 days of age, sera, gastrointestinal and male and female reproductive system samples were taken from Japanese quail chicks reared under three different stocking densities (44, 88 and 176 bird/m2). The obtained data clearly showed that increasing stocking density was associated with marked significant decrease in weight and length of the gastrointestinal tract as well as the length of the stomach as proportion to the gastrointestinal tract length. In addition, gastrointestinal tract weight as percent of body weight, esophagus weight as percent of gastrointestinal weight, duodenum length as percent of gastrointestinal length and small intestine weight as percent of gastrointestinal weight were significantly increased (P < 0.05) with increasing stocking density. Moreover, increasing stocking density induced morphological atrophy in the testes, ovaries and oviducts and this atrophy was associated with a sharp reduction in the testosterone and estradiol hormone levels in the sera. Significant reduction (P < 0.05) in blood AST and significant increase (P < 0.05) in serum total lipids were also observed.
