Resumo: | The experiment was conducted at Centro Nacional de Pesquisas de Caprinos, Sobral, CE, Brazil, to find out possible causes of urolithiasis and plan prophylactic measures. Eight castrated bucks, divided in two equal groups (T1 and T2), were submitted to a diet of 59.5 g/day of corn meal and 40 g/day of cottonseed cake with ad libitum supplementation of elephant grass (Pennisetum purpureum, Schum.) for 180 days under confinement. The bucks in T2 also recieved 0.5g of ammnonium chlorate per 100 g of ration. Seven bucks (87,5%), three T1 and four T2, showed urolithiasis. The first symptoms appeared after 92 days, but major part of animals showed symptoms around 120 days of the experimentation. Urine pH of T1 and T2 were comparable. Blood-serum examination of affected animals revealed a high concentration of magnesium and phosphorus. The post-mortem demonstrated presence of calculi in bladder, ureters and urethra. The calculi were composed of phosphates of ammonia, calcium and magnesium. The amount of ammonium chlorate used in the rations as a possible prophylaxis did not reduce the incidence of urolithiasis. The formation of calculi, therefore, may be due to a complexity of causes, such as composition of rations, confinament, and early castration or a combination of these factors. |

Oito caprinos machos, castrados, confinados durante 180 dias, com uma dieta alimentar contendo capim-elefante (Pennisetum purpureum Schum.) ad libitum, 59,5 g/dia de milho, 40 g/dia de torta de algodão e 0,5 g/dia de sal comum, foram divididos em dois grupos, T1 e T2. O grupo T 2 recebeu 0,5 g/100 g ração/dia/animal de cloreto de amônio na ração. Sete caprinos (87,5%), três de T 1 e quatro de T 2 , apresentaram urolitíase. Os primeiros sintomas apareceram aos 92 dias; a média foi de 120 dias após o início do experimento. Não houve diferença no pH da urina dos grupos T 1 e T2. O exame de sangue revelou, nos animais afetados, alta concentração sérica de magnésio e fósforo. Post mortem foram encontrados cálculos na bexiga, ureteres e uretra. O exame químico destes revelou fosfato de amônio, cálcio e magnésio. A quantidade de cloreto de amónio utilizada na ração, como profilático, não diminuiu a incidência de urólitos. Atribuiu- se a formação dos cálculos a um complexo de causas: dieta, estabulação e castração precoce, ou à combinação destes fatores.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraUnanian, Maria MarinaRosa, Janete SantaSilva, A.
