May and plasma LH concentrations were analyzed and compared by ANOVA and t-­test. Plasma LH concentrations were high and did not differ between groups during the breeding season (Nov-­Feb; SAR: 2.00 ± 0.34; C: 1.88 ± 0.16; ISO: 1.67 ± 0.51 ng/ml). In contrast, from Mar to May, LH plasma concentration decreased to very low levels in the C and ISO groups (1.30 ± 0.20 and 0.48 ± 0.04 ng/ml, respectively)

ciation between pregnancy rate and other ultrasound characteristics of the reproductive tract during estrus was observed in this study (p > 0.05). In conclusion, follicle size is positively associated with pregnancy rate of dairy cows in estrus. However, other ultrasonographic findings of the uterus including intrauterine fluid did not show any association with pregnancy rates.

Nanotechnology has allowed sperm selection in human, bull and boars but its effect on freezability is not yet reported. In our study we aimed to use magnetic iron oxide nanoparticles (np) coated with annexin-­V, silica magnetite and pisum sativum agglutinin obtained from Clemente Associates on goat sperm and analysed the effects on sperm parameters after thawing. We used different concentra-

The cauda epididymis is a good sperm source in case of an unexpected decease or castration. We aimed to elucidate if canine epididymal sperm is better preserved at 4°C within the epididymis or in an extender. Testicles were retrieved after neutering and one epididymis was dissected and cooled for 24 h and the other was flushed, sperm were extended in CaniPlus Chill® at 100 × 106 sperm/ ml and preserved at 4°C. After 24 h of cooling, the other epididymis was flushed and processed as the former. Samples when then centrifuged, and the obtained pellet was resuspended at 100 × 106 sperm/ ml in CaniPlus Freeze® medium. Sperm were packed in 0.5 ml straws, cooled at 4°C (1 h) exposed to LN2 vapors for 20 min and plunged in liquid LN2. Sperm quality was evaluated after thawing (37°C for 1 min). Total motility (TM) was estimated with a CASA system, while

A total of 9 semen samples were collected and extended with Tris-­based extender. Samples were then divided into 3 groups; (1) control (2) 1 μg/ml and (3) 10 μg/ml np selection. Samples in control group were directly placed in 0.25 French straws, equilibrated for 1.5 h, frozen and stored in liquid nitrogen. In groups 2 and 3, samples were treated with 1 or 10 μg/ml of nanoparticles, then processed and stored as the samples in control group. After thawing, the samples were analysed using SCA, CASA. The np treated groups were significantly different from the control group in VCL and VAP (p
