The impact of rapid on-site evaluation (ROSE) on thyroid aspirates has been a matter extensive debate. In the current study, authors reviewed all fine-needle aspiration biopsies (FNABs) performed in their service recent years to evaluate ROSE final adequacy and diagnostic rates.All ultrasound-guided FNABs between July 2015 2017 were included retrospectively. was by experienced cytopathologists, with production Romanowsky-stained slides for immediate evaluation. When not performed, total 3...
Context In vivo embryo production, also called multiple ovulation and transfer, can accelerate genetic gain, thus improve animal production. However, there are issues limiting a wider use of this biotechnology in sheep livestock. Aims This study aimed to determine (1) whether previous response superovulation (SOV) be used as criterion select ewes for (2) the intensity SOV (number corpora lutea, CL) affect recovery rate, (3) number CL quantified by colour Doppler ultrasonography calculate...
The present study evaluated the effect of four ovarian stimulation protocols on follicular population and molecular status cumulus-oocyte complexes (COCs). Twelve Santa Inês ewes (in a cross-over design) received 80 or 120mg FSH alone in multiple-dose (MD80 MD120) regimen combination with 300IU equine chorionic gonadotrophin (eCG) one-shot (OS80 OS120) protocol. population, COC recovery rate, mean COCs per ewe rate brilliant Cresyl blue-positive (BCB+) were similar among treatments (P>0.05)....
This study was designed to investigate the effect of early weaning and concentrate supplementation on performance metabolic profile lambs in four production systems pasture: suckling not supplemented until slaughter; with creep feeding weaned slaughter. Performance assessed by average daily gain (ADG) body condition score (BCS) measurements. Metabolic delineated measuring serum albumin, urea, creatinine, cholesterol, glucose aspartate aminotransferase. Weaning reduced ADG 92 g/d for were 113...
The study aimed to evaluate the effectiveness of combining two injectable progesterone (iP4) formulas for estrous synchronization in ewes and compare it with traditional intravaginal devices. Additionally, assessed whether inclusion GnRH enhances reproductive outcomes iP4 treatment. Two experiments were conducted. In first experiment, 20 Santa Inês divided into groups: one group received devices, other combined long-acting short-acting iP4. second 30 Corriedale GnRH, without GnRH. Estrous,...
(1) Background: Leptospirosis, mainly determined by strains belonging to serogroup Sejroe, has a direct impact on the reproductive efficiency of ruminants, such as sheep. In Brazil, Leptospira santarosai serovar Guaricura, known be able chronically colonize uterine environment, is special note. Although vaccination minimizes effects acute disease, whether or not it can protect from renal colonization remains controversial, and its genital tract are unknown. this context, present study aims...
This study evaluated the cervical transposition method as a tool to select ewes for embryo collection by transcervical route. Adult Santa Inês (n = 50) received Day 0 protocol superovulation treatments. The cervix test was performed both at oestrus and time. latter preceded hormonal dilation. sensitivity, specificity, positive predictive value, negative value accuracy were 85.7%, 66.6%, 66.6% 80.0%, respectively. kappa index yielded moderate score (κ 0.52). In conclusion, high sensitivity...
Abstract The aim of this work was to determine whether a cervical dilation protocol (CDP) composed only oxytocin can be used perform transcervical (non‐surgical) embryo transfer in sheep (NSET) without affecting the viability corpus luteum (CL). Likewise, we evaluated transposing test with Hegar dilator (CT test), performed at oestrous time, could screen ewes for NSET (greater or lower chances transpose cervix). For that, and ovulation synchronization 25 Santa Inês induce dioestrous...
Information on the impact of hormonal protocols for cervical dilation quality ovine embryos is scarce.To compare after protocol, ewes (n = 64) were allocated into either a treated group (100 μg estradiol benzoate intravenous and 0.12 mg cloprostenol intramuscularly, 12 hours before embryo collection plus 100 iu oxytocin 15 minutes procedure) or control (saline). Luteal function was analysed using ultrasonography P4 measurement. Some collected frozen/thawed gene expression, others cultured in...
