“…But at the same time shearing of their fleece gave them an opportunity to balance their body temperature better than the unshorn counterparts. A similar result have been reported by Heath et al (2001) who have reported that whole body shearing of alpacas could have a beneficial effect on thermoregulation in a hot environment. And also, Pennisi et al (2004) reported that shearing reduces heat stress in dairy sheep.…”

The aim of this study was to analyze the effects of shearing on the individual behaviors and rectal temperature profile during the day at hot environment in Awassi lambs. Twenty Awassi male lambs were randomly allocated into shorn (n = 10) and unshorn (n = 10) groups (28.8 ± 0.7 and 29.9 ± 0.7 kg, respectively) and were kept indoor during the experiment. The physiological and behavioral response variables measured were rectal temperature, standing, lying, feeding, ruminating, drinking, locomotor activity, and elimination. The effect of day, time of day, and all interactions on rectal temperature were found significant (P < 0.001). The effect of shearing on the rectal temperatures of lambs was tend to be significant (P = 0.06). Overall, unshorn lambs showed more frequencies of locomotor activity (P < 0.05) and there was a tendency of less standing behavior (P = 0.08) when compared to the lambs in shorn group. The difference of the other behaviors was not significant (P > 0.05). Within the observation hours, there was a tendency of difference for behavioral frequencies between groups especially early in the day and late at night (P = 0.07). But during the day, the difference of behavior type between groups was highly significant at 1300 and 1600 hours (P < 0.01 and P < 0.001, respectively). The findings of the current study showed that the behavior of shorn lambs changed with the changing of environmental heat and showed more behavioral differences at 1300 hours but they tend to cope with heat stress better than unshorn lambs in a hot environment when their rectal temperatures were compared.

“…This phenomenon is consistent in multiple species (equids, llamas, dogs) and occurs because of the insulating properties of the hair coat. Readings after hair coat removal maybe elevated because they are representative of the actual skin temperature 22,23,51–54 . Our study design was based on a previous dog study that found normalization of skin temperature 1 hour after clipping 54 .…”

“…Our study design was based on a previous dog study that found normalization of skin temperature 1 hour after clipping 54 . It is unknown if the thermographic pattern and changes in the temperature scale found in dogs after clipping the hair coat would show continued cooling after 24 hours as reported in llamas 53 . The impact of the length and thickness of the hair coat on the thermographic pattern and temperature scale remains unknown.…”

“…12 In another study, whole-body sheared alpacas had a lower body temperature compared with nonsheared alpacas, and thermography of the scrotum and medial thighs revealed lower surface temperatures in sheared alpacas. 13 At the time of shearing, the feet and teeth should be examined and trimmed as needed. Camelids have a toenail around a soft footpad, rather than a hoof, and this toenail should be trimmed flush with the soft pad using small shear-type foot-trimming Fig.1.…”

The area of herd health is particularly important when considering camelid operations because of the high frequency of travel for exhibition, breeding, and boarding. This article outlines the considerations for routine husbandry, facility and animal maintenance, and infectious disease control in the form of biosecurity, vaccination, and health testing that should be included in any farm's herd-health plan. Veterinary input into the design of programs for biosecurity and infectious disease prevention is critical and requires an active veterinary client-patient relationship with identification of the goals of the operation. Risk assessments should be made based on farm activities and should be the foundation for herd-health program design.
