Abstract:
BACKGROUND
Ascites is a metabolic disease that has negative effects on broiler chickens.
OBJECTIVES
This study was performed to investigate the effect of cold induced ascites on performance, meat quality and quantity indices and some blood indices of broiler chickens with cold induced ascites.
METHODS
Three hundred one-day-old female chicks (Ross 308) were used in a completely randomized design with two treatments of control (under normal temperature) and ascitic (under cold stress) with five replicates and 30 birds per each replicate.
RESULTS
The results showed that cold-induced ascites caused the lower performance, carcass weight and thigh and breast meat (P<0.05). Furthermore, ascites caused the increased anus temperature and thigh lightness (L) and redness (a) at day 42 of age (P<0.05). Cold induced ascites decreased the enzymes of glutathione peroxidase and superoxide dismutase, uric acid, albumen and malondihaldehyde in blood at day 42 of age (P<0.05). The higher blood hematocrit and hemoglobin were observed in ascetic birds (P<0.05).CONLUSIONS: In conclusion, cold induced ascites increase the meat lightness through the increased peroxidation and decreased antioxidants of the body. Moreover, ascites cause the higher anus temperature by increasing the body basal metabolism.
