To investigate whether AFC and circulating AMH could predict follicle development and oocyte quality during the prepubertal period we used 40-day-old ewe lambs with high, intermediate and low AFC (≥30, 16–29 and ≤15 follicles respectively). The analysis of the response to the exogenous FSH ovarian reserve test showed a positive correlation between AFC, AMH plasma levels, total follicle number and the number of large follicles (≥3 mm) grown after exogenous FSH administration. The incorporation of abattoir-derived oocytes collected from ovaries with different AFC in an in vitro embryo production system showed that a high AFC can predict oocyte quality in prepubertal ovaries, reflecting an ovarian status suitable for follicular development. The histological quantification of the ovarian reserve evidenced that AFC was not predictive ...

Fine needle aspiration cytology (FNAC) is a fast and inexpensive technique well-tolerated by animals. Few reports have shown how difficult cytological diagnosis of CMT is and how difficult benign or malignant tumours are to classify using FNAC. Cytological diagnosis has often been inconclusive in veterinary pathology. In the diagnosis of human breast cancer, FNAC efficacy is beyond doubt due to its high specificity. In this preliminary study, our aim is to evaluate the efficacy of NHSBSP classification, applied to CMT. Secondly, we wish to test the usefulness of H&H stain in FNAC for CMT diagnosis. 75 FNAC specimens, from 41 dogs with mammary tumours were examined. 72/75 underwent the NHSBSP classification Histological examination of the tumours was performed in each case for comparison purposes. All the CMTs fell under the five categories: C1 (3 cases), C2 (7 cases), C3 (38 cases), C4 (15 cases), C5 (9 cases). A...
