The aim of the present study was to assess the effect of storage time at +4 °C on haematological profile in goat (n = 25) and sheep (n = 25). After collection, blood samples were immediately analyzed and then divided into four aliquots that were stored at 4 °C and tested at 24 h (T1), 48 h (T2), 72 h (T3), and 1 wk (T4), respectively. One-way repeated-measures analysis of variance (ANOVA) was used to determine statistically significant effect of storage conditions both in goats and in sheep. Our results showed that among the two species studied, goats showed highest blood stability after refrigeration at +4 °C. In goats, all hematological parameters, except PLT, showed no significant changes during all days of monitoring with respect to basal values (T0). In sheep, no significantly effect of storage time on RBC and WBC levels were found, whereas the other hematological parameters change significantly over the time. Our findings suggest that the blood storage time reported for goat may not be applied to sheep’s blood, which underscore the differences between these two species that are erroneously considered similar. © 2016, Agricultural Institute of Canada.

The aim of this study was to evaluate Pb and Cu accumulation in muscle and skin samples of red fox (Vulpes vulpes) from Sicily, for monitoring of environmental metals pollution. Metals determination, carried out by atomic absorption spectrophotometer (AAS), showed the presence of Pb and Cu in all samples analyzed. Pb concentrations were similar in muscle (0.04±0.009. mg/kg) and skin (0.03±0.004. mg/kg) samples, while Cu levels resulted higher in muscle (1.842±0.178. mg/kg) than in skin (1.22±0.151. mg/kg). In addition, a comparative analysis of Pb and Cu concentrations was carried out among samples from different areas of Sicily and between female and male, young and old, immature and mature foxes. Metals content found in all muscle and skin samples demonstrates that V. vulpes could be a valid "sentinel" species of rural and suburban areas to study the environmental metals pollution and the habitat quality. © 2012 Elsevier Inc.
