EFFECT OF DIFFERENT DIETARY CALCIUM AND PHOSPHORUS RATIO ON URINARY SYSTEM AND INCIDENCE OF GOUT IN BROILER CHICKS (Pages : 19 - 23)

An experiment was conducted evaluate the effects of different dietary calcium and phosphorus ratio on urinary system and incidence of gout in broiler chicks on One hundred and twenty healthy broiler chicks that were selected and randomly divided into three groups as group A, B and C in which group A was control. The different groups were given three experimental ration containing calcium and phosphorus ratio as 1.50:0.5 (control), 2.50:0.5 and 3.5:0.5 were given for group A, B and C respectively for 28 days of experimental period. The biological parameters like serum calcium and phosphorus concentrations, FCR, kidney: body weight ratio was studied. Pathological examination of urinary system, pericardium, liver and visceral organ surfaces were performed. Chicks fed with high dietary calcium and phosphorus ratio showed hypercalcaemia, hypophosphataemia and increase incidence of visceral gout. In treatment groups the FCR and mean kidney: body weight ratio was higher. The ureters also showed occlusion and distention. The kidneys showing gross pathological lesions revealed common histopathological changes in glomeruli, tubular cells and interlobular veins. In general the urinary system of the treated birds, displayed inflammatory lesions, showing abnormalities of colour, size, shape and texture of kidneys and ureters. The rate of uric acid, urea, total protein, albumin, creatinine, calcium and alkaline phosphatase had meaningful changes compared control with group (p<0.05). Deposition of urates in kidney, on heart serous surfaces, liver, mesenteric and peritoneum were displayed in treatment group.Download
