일반농장과 동물복지농장 닭의 혈액 내 gas, 생화학인자, 호르몬 농도 및 근육 내 스트레스 반응인자 비교 (Comparison of Blood Gas, Biochemical Factors, and Hormone Concentrations, and Muscle Stress Response Factors of Chickens in General Farms and Animal Welfare Farms)

초록

It is generally recognized that high stocking density can increase the risk of immune dysfunction and reduction in productivity cause of elevated stress in broiler farm. The domestic livestock industry is implementing a certification system for animal welfare and livestock farms to reduce the problem of dense breeding. This study compared broiler from the general farm and animal welfare farm to confirm the effectiveness of animal welfare farms against stress. Gas concentrations in a farm of general and animal welfare farms were analyzed, blood (n=10) of the 28-day-old broiler was collected, the partial pressure of the gas in the blood was analyzed using whole blood, and biochemical factors and hormones were analyzed using the serum. Glycogen and L-lactate are analyzed using ELISA kit on finely pulverized muscles (n=10). CO2 and NH3 levels in the farm were significantly higher in general farm. Partial carbon dioxide tension (PCO2) in blood was significantly higher and partial oxygen tension (PO2) was significantly lower in the general farm. Creatinine (CREA), glucose (GLU), aspartateaminotransferase(AST), and creatinekinase (CK) in the blood were significantly higher in the general farm, and total protein (TP) and globulin (GLOB) were significantly higher in animal welfare farm. Blood corticosterone and norepinephrine were significantly higher in general farm and epinephrine was significantly higher in animal welfare farm. These results imply that animal welfare farm provides a stress-reduced breeding environment.
