<p><strong>Abstract.</strong> The aim of this study was to evaluate the effects premating ewe weight and age on reproductive performance, lamb growth survival in Central Anatolian Merino (CAM) sheep. <br><br> trial included 4935 ewes 5548 lambs from 23 breeder flocks Eskişehir Province. live weights (LWs) ages were recorded 1 week before mating season. number born, fertility rate, multiple birth rate (MBR), (SR) at days 75 120 determined. LW found be important...
Cryoprotectants are known to have protective effects against cryodamage spermatozoa. In this study, the cryoprotective of two cryoprotectants (glycerol, ethylene glycol) and cryoprotectants/trehalose combinations on frozen-thawed ram spermatozoa were investigated at ultrastructural level. For purpose, ejaculates collected from Konya Merino rams pooled diluted with a tris-based extender containing additives, including 5% glycerol, 3% glycerol +60 mM trehalose, 1.5% +100 glycol, glycol...
Abstract The aim of this study was to evaluate the effects transfer side, location, cervix score, type and diameter corpus luteum (CL) during embryo on pregnancy rates in beef heifers. Progesterone‐based synchronization superovulation protocol were applied Simmental cows used as donors ( n = 168). Uterine flushings performed day 7 following artificial insemination. Obtained Code I (excellent or good) II (fair) quality embryos transferred recipient heifers 561). During transfer, side (right...
The purpose of the present study was to assess effects ellagic acid and ebselen on sperm oxidative stress parameters during liquid preservation ram semen.In this experimental study, sixty ejaculates from six mature Merino rams were used. In experiment 1, diluted in base extender contained at 0 (control), 0.5, 2 mM. 2, 10, 20, 40 μM added extender. Sperm motility, viability, mitochondrial membrane potential, DNA integrity, lipid peroxidation (LPO), antioxidant potential (AOP), total...
Freeze-thawing process negatively affects ram spermatozoa in terms of sperm quality, DNA integrity and antioxidant defence system. Thus, supplementation during freeze-thawing is suggested to improve parameters.The aim this study was determine the effects fetuin trehalose added into semen extender on parameters, antioxidant-related gene expressions process, low glycerol concentration.Semen samples collected from six mature rams were pooled splitted equal aliquots diluted with a tris-based...
Background: The hair goat of Anatolia is a breed that has adapted to rugged and mountainous areas known be very resistant diseases. As the world faces problem climate change, we believe knowing hematological characteristics goats will provide great benefits for breeding. Objectives: This study was performed determine possible differences in blood parameters adult (male female) during out breeding season. Methods: For this purpose, samples were taken from clinically healthy male female (n=36,...
Sperm cryopreservation has been widely used in the field of reproductive biotechnology. It applies to certain males economic and scientific values, including livestock breeds or endangered animal species. The development a semen extender with low cryoprotectant concentration an appropriate amount trehalose boron can prevent deterioration sperm parameters.The main goal this study is establish suitable ram model, by examining different combinations high (5%) (3%) glycerol concentrations (to...
MicroRNA (miRNA) plays an important role in the control of gene expression and is implied many biological functions, including embryo implantation development. The aim was to assess plasma miRNA profiles during peri-implantation ascertain potential candidate markers for early pregnancy diagnosis ovine plasma. samples were obtained from a total 24 ewes on days 12 (pre-implantation; P12, n = 4), 16 (implantation; P16, 4) 22 (post-implantation; P22, after mating, their corresponding (Pre-C;...
Abstract The most significant focal points of the embryo transfer technology are as follows: selection donors, response selected donor to superovulation protocol and obtained number transferable embryos. For this purpose, it is suggested that can be done by anti‐Müllerian hormone (AMH) levels, production evaluated. AMH secreted granulosa cells primordial, pre‐antral antral follicles below 4 mm in ovary, independent FSH. Therefore, aim study was investigate relationship between serum levels...
In the present study, it was aimed to investigate effect of lactation status, days in milk (DIM), follicle stimulating hormone (FSH) dose, and repeated superstimulations on superovulation response embryo yield Simmental cattle. 193 breed cattle (lactating, nonlactating, heifer) were used as donors, which 149 superovulated only once other 44 for 3 times. Progesterone-based estrus synchronization protocol applied donors. Starting from day 7, FSH given intramuscularly donors decreasing doses...
This study aimed to determine the effect of flunixin meglumine treatment during and after transfer in vivo produced embryos Angus (cows) Holstein (cows heifers) breeds cattle on pregnancy rate. cows were used as donors study. A double dose prostaglandin F2α was administered recipient animals for synchronization. Uterine flushing performed day 7 artificial insemination. total 295 transferable obtained. These transferred (n = 85), heifers 80) 130). After transfer, these divided into three...
Öz: Çalışmada, Akkaraman koyunlarda Flushing + Koç etkisi ya da farklı dozlarda gebe kısrak serum gonadotropini (PMSG) uygulamalarının kuzu verimi üzerine araştırıldı.Bu amaçla 124 baş koyun, çalışmanın başlangıcında rastgele beş gruba ayrıldı.Bu grupları, PMSG300 (n=25), PMSG500 (n=24) ve PMSG700 Etkisi (n=25) Kontrol grupları oluşturdu.PMSG gruplarında östrüsler vagina içi 20 mg fluorogestone acetate içeren sünger (12 gün süreyle) ile senkronize edildi süngerlerin çıkarılmasından 24 saat...
In this study, the aim was to obtain pregnancy following synchronization and increase profitability in ewes that did not become pregnant during breeding season after at least 3 matings. Nonpregnant Middle Anatolian Merino (n = 117) were given a progesterone sponge for 9 days. At time of removal, received 250 IU mare serum gonadotropin (PMSG) + 125 µg prostaglandin F2α (PGF2α). Two days later, they injected with either human chorionic (hCG) (Group I, n 48) or gonadotropin-releasing hormone...
The aim of this study was to investigate the efficacy different short term synchronization protocols on estrus and pregnancy rates in merino ewes that had not become pregnant after at least three matings during breeding season. Three were used as follows: Group I: Ewes (n=30) inserted intravaginal progesterone sponge (florogestan asetate; 30 mg) for 6 days plus PGF2α (125 μg, i.m.) time removal, II: (40) treated same group 1 eCG (250 IU, III: (n=38) only injected with other two groups....
Small ruminants bring unproductive pastures to the economy with products such as meat and milk. Although management of Hair goats is difficult compared that sheep, they make better use than sheep. The birth rate high, but multiple quite low. This study aimed determine relationship between antioxidant paraoxonase-1 (PON-1), offspring yield in goats. In second week September, 100 females were randomly selected blood samples taken 15 days before introduction male herd from both males females....
