Urinary Calculi in Sheep

Four Japanese Black steers (16 months of age) were assigned to a 4 × 4 Latin square design to investigate the effect of graded levels of sweet-potato condensed distillers solubles (SCDS) in their diets on intake and urinary excretion of minerals. The four diets consisted of 0%, 10%, 20% and 30% (dry matter (DM) basis) SCDS, with SCDS replacing commercial concentrate (CC). Intake of K, Cl, S, P and Mg increased linearly with increasing SCDS content. Urinary pH increased linearly with increasing dietary SCDS content. SCDS feeding increased urinary K concentrations (linear and quadratic effects). Urinary concentrations of Cl increased linearly with increasing SCDS content. In contrast, urinary concentrations of Mg decreased with increasing SCDS content. Feeding of SCDS did not apparently affect urinary NH ,P, Na or Ca concentrations. These results suggest that high SCDS feeding is not a risk for crystallization of minerals leading to the formation of magnesium-phosphate type calculi: although SCDS contains large amounts of P and Mg, high SCDS feeding decreased the Mg concentration and did not affect the P concentration in urine. Additionally, high SCDS feeding had no apparent effects on plasma concentrations of Na, K, Cl, Ca or inorganic P.

“…No entanto, Lindley et al (1953) não observaram interferência da vitamina A na ocorrência de urolitíase em ovinos. Radostits et al (2010) citaram que um adequado consumo de vitamina A deve ser assegurado durante os períodos de seca e quando os animais forem alimentados para engorda com ração que contenha grãos.…”

RESUMO.A urolitíase é um processo patológico caracterizado pela presença de cálculos ou concreções no sistema urinário. De etiologia complexa e multifatorial, caracterizada pela formação de urólitos, que se alojam no trato urinário e preocupam à medida que determinam sua obstrução, passando a ser denominado de urolitíase obstrutiva. Os primeiros sinais clínicos manifestados pelos animais com urolitíase obstrutiva estão relacionados à dor. Objetivou-se com esse trabalho uma atualização sobre o quadro patológico de urolitíase obstrutiva em ovinos, abordando desde seu histórico, etiologia, epidemiologia, patogenia, sinais clínicos, diagnóstico, diagnóstico diferencial, tratamento, controle e prevenção. Palavras chave: obstrução, ovino, urolitíase Urolithiasis obstructive in sheep: ReviewABSTRACT. Urolithiasis is a disease process characterized by the presence of calculi or concretions in the urinary tract. Complex and multifactorial etiology, characterized by the formation of uroliths, that lodge in the urinary tract and care as they determine their obstruction, becoming known as urolithiasis. The first clinical signs in the animals with urolithiasis are related to pain. The objective of this work an update on the pathological picture of obstructive urolithiasis in sheep from addressing its history, etiology, epidemiology, pathogenesis, clinical signs, diagnosis, differential diagnosis, treatment, control and prevention.

“…Since the degree of ionization of phosphate to the trivalent phosphate ion in urine is very dependent on pH, the above finding suggests a positive correlation between calculus formation and the concentration of the trivalent phosphate ion. Increasing the dietary intake of phosphorus in general increases the output and concentration of phosphorus in urine (Elam, Ham & Dyer, 1959;Bushman, Emerick & Embry, 1965) and the incidence of calculus in ruminants given a calculogenic diet (Bell & Kirk, 1935;Lindley, Taysom, Ham & Schneider, 1953;Emerick & Embry, 1963). There is not, however, an absolute relationship between the concentration or the total amount of phosphorus in urine and the incidence of calculi.…”

Urolithiasis is not at present an important problem for the livestock industry in the United Kingdom, but the probable introduction of more intensive systems of management may change this position. The rapid fattening of male animals with high-energy diets predisposes to formation of phosphatic calculi and obstructive urolithiasis in the feed lot system of the USA and it is a form of this type of management which is most likely to be introduced to this country. For this reason, this review will be limited to the problem of phosphatic calculus formation, although other calculi, especially siliceous forms cause economic loss in extensive areas of the world.
