Forty Valle del Belice ewes, clinically healthy and well-fed, were divided into two groups of twenty subjects each. Twenty ewes were left unshorn as a control group (Group A) and twenty ewes were shorn (Group B). After the blood collection by means of jugular venipuncture, some haematochemical parameters were assessed for each subject in the following experimental conditions: before shearing, 1st, 15th, 30th, 45th, 60th and 75th day after shearing. We studied the course of the following haematochemical parameters: concentrations of glucose, beta-hydroxybutyrate, NEFA, triglycerides, total cholesterol, total proteins, urea and creatinine. There were significant differences in beta-hydroxybutyrate, NEFA, total proteins and urea concentrations. The studied variables were significantly influenced by the time. These results suggest that shearing induces adaptive metabolic responses in ewes and exposure to elevated ambient temperature induces modifications of some haematochemical parameters.
