Análisis Microbiológico, Patológico Y Determinaciones De Microelementos en Vicuñas Afectadas Con "Caspa".

“…La posible asociación de deficiencia de zinc e hiperqueratosis tampoco puede descartarse, pero es necesario mencionar ciertas discrepancias alrededor de posible relación de deficiencia de zinc e hiperqueratosis idiopática en llamas y alpacas (Foster et al, 2007), dado que las concentraciones de zinc en llamas y alpacas son menores a lo reportado en ovejas y vacas. Asimismo, las lesiones dérmicas en el 25% de animales con bajas concentraciones de zinc, ocurren principalmente alrededor de la nariz y orejas (Clauss et al, 2004), lesiones no observadas en los animales estudiados.…”

Cutaneous candidiasis infection in two alpacas

“…In a study by Clauss and others in 2004, skin lesions associated with zinc deficiency were more common in alpacas with darker fleeces (Clauss and others 2004). Authors postulated that the increased demand for zinc to maintain a darker fleece creates a higher relative mineral metabolism (Clauss and others 2004). Interestingly both alpacas in this case report had dark fleeces.…”

“…Reported normal reference ranges for serum and plasma zinc concentrations in camelids are widely variable (Clauss and others 2004, Van Saun 2009). Specifically for alpacas, normal serum and plasma zinc concentrations are lower than that of llamas, sheep, cattle and goats (Clauss and others 2004, Krametter-Froetscher and others 2005, Judson and others 2011).…”

Ichthyosis in a Nigerian Dwarf Goat

“…The keratinization defect in alpacas 22) is primarily orthokeratotic. The measurement of serum or blood concentrations of zinc cannot reliably separate affected animals from normals 3,4,14,24) . The dermatosis responds completely and rapidly to zinc (eg.…”
