Introduction: Foot quality is essential to the horse’s movement. The barefoot approach favours the animal’s welfare. Environment and selection determine hoof characteristics. Material and Methods: Hoof characteristics of eight Anglo-Arabian (AA) and nine Haflinger (HA) horses were studied. After a preliminary visual analysis of feet, nail samples were collected after trimming for physico-chemical analysis. The parameters were submitted to analysis of variance. A principal component analysis and a Pearson correlation were used to compare mineral contents. Results: The hooves of both breeds were healthy and solid. The hooves of HA horses were longer than those of AA horses (14.90 ±0.30 cm vs 13.10 ±0.60 cm), while the AA hoof was harder than the HA hoof both in the wall (74.55 ±2.95 H vs 60.18 ±2.67 H) and sole (67.00 ±5.87 H vs 43.0 ±4.76 H). In comparison with the sole, the AA hoof wall also had a lower moisture percentage (12.56 ±0.67% vs 20.64 ±0.76%), while crude protein and ash contents were similar in both regions. The AA hoof showed a higher Se content, while the HA hoof had a higher level of macroelements. The negative correlations of K with Cu, Fe, Ni, Pb, and Zn in the AA hoof may indicate osmoregulation activity. Conclusion: The hoof morphology of AA and HA horses met the literature parameters for mesomorphic horses. Both breeds had healthy and well-conformed hooves, useful for sport and recreation activities.

Several physiological variables related to salinity acclimation in Liza abu were examined, using oxygen consumption rate and glucose level as an indication of osmoregulatory energetic. l~'reshwater acclimated I.. aim were transferred to two salinity (7 and 15 g/L) oxygen consumption rates. glucose levels and plasma ion concentrations (Na i. K’) were measured after three days of transfer to higher salinity. Plasma ion concentrations were elevated after transfer. Blood glucose level increased after transfer to salinity 7 g/L while its level decreased in salinity 15 g/L compared to its level in freshwater. Oxygen consumption rate increased one and half time of that in freshwater but no significant difference were noticed in oxygen consumption rates between fish in both salinities (7 and 15 g/L) .'l'he amount of metabolic energy consumed during salinity acclimation were also determined. The result showed that the physiological changes associated with salinity acclimation impose a significant short - term energetic cost.
