Abstract
T
he The current study is designed to investigate the impact of overcrowding alone and overcrowding with a Green Tea extract, on various physiological aspects of Japanese quails. To achieve that a total of 45 six-weeks-old male quails were used and divided into three main groups, the first control group was bred under normal conditions with a stocking density of (15 birds/1m2), while the second group which had 15 birds divided into three replicates (3*5) and subjected to an abnormal stocking density of (75 birds/1m2), the third group also had 15 birds divided into three replicates (3*5) and also subjected to a same abnormal stocking (75 birds/1m2) but supplemented with a Green Tea water extract as a drinking water. The breeding continued for 30 days before conducting a several analysis included body weight, liver weight, and numerous serum and blood parameters as well as liver functions. The results revealed a negative effect of overcrowding on lymphocytes, body weight, total protein, albumin, and globulin, as well as many hematological parameters (Hb, PCV, RBCc, WBCc, and MCHC). Other parameters were increased in the overcrowding state, like heterophil, basophil, liver weight, ALT, AST, MCV, and NCH. While the treatment with green tea extract increased each lymphocyte, basophil, neutrophil, and monocyte, it also elevated the values of body weight, total protein, globulin, and the majority of hematological parameters (Hb, PCV, RBCc, WBCc, MCHC); others were decreased, like heterophil, ALT, MCV, and MCH.
