Sweating in the guanaco (Lama guanicoe)

Journal of Thermal Biology, 2001
Sweat glands are present all over the skin, where sweat production varies from 4.98 to 73.36gm(-2)h(-1) of skin. Ambient temperatures between 20 and 33 degrees C are the main stimuli for activation of sweat glands, generating a heat loss ranging from 11.9 to 37% of standing basal metabolic rate.

Seroprevalence of Neospora caninum in Camelids of the New and Old World: A Global Systematic Review and Meta-Analysis. [PDF]

Vet Med Sci
Based on the present systematic review and meta‑analysis, the pooled prevalence of N. caninum in camelids was 10% (95% CI: 7%–12%) with significant heterogeneity (I2 = 93.75%, p < 0.0001). The highest rate was detected in Old World camelids, 14% (95% CI: 10%–19%), indicating that this group is more susceptible to N. caninum exposure.
