The aim of this study was to establish the influence of shearing in dairy sheep during summer season. Several physiological and haematological parameters, which are closely related to thermoregulatory potential, have been investigated with the purpose to assess shearing influence on thermoregulation. Forty dairy sheep, clinically healthy and well-fed, were used. They were divided into two group...

Some occupational health and safety hazards associated with sheep shearing are related to shearing shed design. One aspect is the floor of the catching pen, from which sheep are caught and dragged to the shearing workstation. Floors can be constructed from various materials, and may be level or gently sloping. An experiment was conducted using eight experienced shearers as participants to measu...

A quantitative trait loci (QTL) analysis of wool traits from experimental half-sib data of Merino sheep is presented. A total of 617 animals distributed in 10 families were genotyped for 36 microsatellite markers on four ovine chromosomes OAR1, OAR3, OAR4 and OAR11. The markers covering OAR3 and OAR11 were densely spaced, at an average distance of 2.8 and 1.2 cM, respectively. Body weight and w...

Alopecia is a frequent complication of cyclophosphamide therapy (13). This side effect has been proposed as a convenient means of defleecing sheep in areas in which mechanical shearing is not available (7). During a study of the metabolism of cyclophosphamide in sheep (3,4), a number of related compounds were prepared as potential metabolites and as model compounds to aid interpretation of spec...

The aim of this research was to investigate how growth hormone (GH) cortisol and some haematochemical parameters could be modified by the stress caused by the stages of shearing in Sarda breed sheep. Five groups of 10 sheep each were formed. Group A, only separated from the flock; Group B, only tied; Group C, both tied and shorn (animals in these three groups were ewe lambs shorn for the first ...
