Objective: The present study aimed to investigate the effect of ovarian laterality on pregnancy outcomes and foal sex, explore role age parity in determining ovulation side Arabian mares. Materials Methods: Material-Methods: Data were collected from 358 mares over a five-year period, during which 885 estrus cycles monitored. was determined using ultrasonography, confirmed days 14, 28, 45 post ovulation. categorized into four groups as 3-8, 9-13, 14-17, ≥ 18 years. Results: evenly distributed...
The aim of this study was to identify the effects adding quercetin (Q) Tris extender in order levels oxidative stress bull sperm after freeze thawing. Ejaculates were collected via artificial vagina from Holstein bulls. Semen divided into five tools and diluted a final concentration 15 × 10
Prediction of male fertility with in vitro semen quality parameters remains a challenge for the bull industry. Fluorescein staining and computer-assisted analysis (CASA) ensure kinetically proper functionally objective results to improve spermatological parameter control. Therefore, we aimed examine CASA kinetic fluorescein cryopreserved its relationship fertility. A total 90 frozen straws from 5 Simmental bulls were evaluated. After was thawed, motility, parameters, insemination doses...
The objective of this study was to determine effects supplementing Tris-based semen extenders with either cholesterol-loaded cyclodextrin (CLC) or 7-dehydrocholesterol loaded (7-DCLC) plus trehalose (T) for cryopreservation ram semen. Semen collected an artificial vagina from five Merino rams (2-3 years age) during the non-breeding season. Ejaculates were pooled, divided into eight equal portions, diluted a standard extender containing: no additive (control); T (50 mM); mM) + 1.5, 2.5 3.5 mg...
The objective was to determine effects of gallic acid (GA) and carnosic (CA), present in carob pods rosemary extract respectively, on frozen-thawed ram spermatozoa. Thirty ejaculates were collected from five Merino rams, pooled, diluted Tris-based extender divided into equal portions containing: 0.05 or 2 mM GA; 0.2 CA; no additive (control). Extended semen equilibrated at +4°C, loaded straws, held 5 cm above liquid nitrogen for 12 min then plunged. Computer-aided sperm analysis used assess...
The aim of the study is to evaluate effectiveness thermographic monitoring, using temperature changes perianal and perivulvar areas for determination estrus in Anatolian Shepherd bitches. Fifteen bitches were used study. Blood vaginal smear samples collected monitoring carried out starting from proestrus early diestrus. Also, external signs investigated. Smear evaluated by light microscopy after Diff-Quik staining method superficial keratinized cells determined as percentage (S + KS%)....
Artificial insemination protocols depend on efficient behavioral estrus detection and time in Angora goat. Therefore, we aim to determine the accuracy of an scoring system goats with different PMSG doses during breeding season. Does (n: 260) were randomly divided into three groups: group-1 93), group-2 85) group-3 82). All animals received intravaginal sponge day 0 for 11 days, insertion 150 μg prostaglandin F2Α was administered. Pregnant mare's serum gonadotropin injected 300, 400 500 IU...
This study aimed to investigate the effectiveness of using red pine bark tree extract (P; Pinus brutia Ten) as a TRIS extender in an attempt prevent oxidative stress bull spermatozoa after freezing. Semen specimens were obtained from Simmental bulls via artificial vagina and pooled. They separated into five diluted with Tris consisting P (200, 100, 50 25 µg/ml) free (control; C) up final concentration 16 × 106 per straw. All equilibrated for period 4 hr at temperature 4°C, following which...
Contents Male reproductive parameters are often used for the functional examination and evaluation of predicted genetic values future aspects. However, these traits relatively reliable until measurable effects expressed on desired traits. Therefore, we aimed to associate single nucleotide polymorphism ( SNP ) genotype investigated characteristics loci. A total 46 male dogs divided into three age groups (I ≤ 3 years, n = 19; II 4–6 years; 19, III ≥7 8). The testis, scrotum body weight, libido...
This study aims to investigate the effect of catechin (CT), green tea extract, as a supplement Tris extender on semen quality parameters in frozen-thawed bull sperm.Ejaculates were taken with artificial vagina from Holstein bulls and divided equal five aliquots, diluted containing different amounts CT (5, 10, 25 50 μg/mL) no-additive (control).All samples equilibrated at 4°C for 4 h frozen using digital freezing machine.Post-thawed sperm motility kinetic determined analyser...
The overall purpose of this study was to describe a method semen collection via trans-rectal digital massage (TDM) and carry out related fertility trial in Angora goat. Sixteen bucks (ranging 1–4 years) 28 nulliparous does (1–2 were used study. Semen samples collected from 85.71% the multiple attempts (18/21). mean values volume, pH, mass motility, total concentration, viability, abnormal spermatozoa rate ejaculation time 0.64 ± 0.09 ml, 6.3 0.21, 2.7 0.34, 58.18 5.1%, 3.68 0.31 × 109/ml,...
The identification of various substances in seminal plasma has opened the way to study their functionality. It was aimed identify electrophoretic protein profile (EPP) and biochemical parameters (BP) (SP) as predictors semen quality fertility stallion. Forty-six ejaculates from 7 fertile stallions, aged between 6-26 years, were collected May July 117 mares used obtain data. For each ejaculate, volume, sperm motility, concentration determined samples perform one- -dimensional electrophoresis...
The aim of this study was to estimate the frequency physiological and pathological reproductive conditions in female Italian Mediterranean Buffaloes.Female animals (n=444), ranging from 3 14 years age were monitored by ultrasonography (USG).A total 7319 USG images collected analyzed for pregnancy status, fetal sexing, gynecological measurements pathologies.While rate determined as 38.75% ovarium-genital canal disorders 11.71%; most common pathologies nonpregnant are defined ovarian cystic...
