Aim. The purpose of this study was to determine ultrasonographic measures of the dorsal subarachnoid space depth in healthy Amiata donkey foals, in order to obtain a range of values to be used as references. Material and methods. The dorsal subarachnoid space depth was recorded in ten Amiata donkey foals at 1 day (T1), 4 (T4) days and 7 (T7) days of life measuring the distance between the dura mater and the dorsal portion of the pia mater in a cross-sectional just cranial to the wings of atlas. The probe was rotated and the longitudinal scan was visualized, then measurements were taken just caudal to the occipital bone at the level of the cisterna magna. Average and standard deviation were calculated. Skeweness-Kurtosis test was applied to verify data distribution. Analysis of variance was applied to verify differences among measurements at different time points. Results. Cross sectional measurements were 0.64±0.05 cm at T1, 0.62±0.07 cm at T4 and 0.65±0.06 cm at T7, while longitudinal measurements were 0.60±0.07 cm at T1, 0.61±0.06 cm at T4 and 0.65±0.05 cm at T7. No differences in dorsal subarachnoid space death were observed at the different times of evaluation. Discussion and conclusions. A correlation between cerebro-spinal fluid (CSF) pressure and ultrasound measurements at the dorsal subarachnoid space depth has been recently reported in the equine foal. This measurement can be considered a safe, reliable and not invasive method to evaluate equine foals with neurologic signs in the perinatal period and to assess indirectly the increase of CSF pressure. The present paper provides an interval range to be used as references also in Amiata donkey foals, as already suggested in equine foals.

Abstract
Aim. The purpose of this study was to determine ultrasonographic measures of the dorsal subarachnoid space depth in healthy Amiata donkey foals, in order to obtain a range of values to be used as references. Material and methods. The dorsal subarachnoid space depth was recorded in ten Amiata donkey foals at 1 day (T1), 4 (T4) days and 7 (T7) days of life measuring the distance between the dura mater and the dorsal portion of the pia mater in a cross-sectional just cranial to the wings of atlas. The probe was rotated and the longitudinal scan was visualized, then measurements were taken just caudal to the occipital bone at the level of the cisterna magna. Average and standard deviation were calculated. Skeweness-Kurtosis test was applied to verify data distribution. Analysis of variance was applied to verify differences among measurements at different time points. Results. Cross sectional measurements were 0.64±0.05 cm at T1, 0.62±0.07 cm at T4 and 0.65±0.06 cm at T7, while longitudinal measurements were 0.60±0.07 cm at T1, 0.61±0.06 cm at T4 and 0.65±0.05 cm at T7.
