A comparison of physical examination and clinicopathologic parameters between sheared and nonsheared alpacas (Lama pacos).

摘要: The purpose of this study was to determine the physiological changes associated with chronic heat stress in sheared versus nonsheared alpacas. Fourteen intact male adult alpacas were randomly assigned one two groups: Group S within 2 cm their skin; NS not sheared. These animals maintained from June through August east central Alabama. Data collected morning, every weeks, included vital signs, body weight, condition score, complete blood counts, serum chemistries and electrolytes, whole selenium, plasma cortisol. groups contrasted using repeated measures analysis variance, pertinent correlations weather parameters calculated.
