Oocytes are exposed to various stressors during in vitro maturation (IVM). Antioxidant supplementation IVM can mitigate oxidative stress. We investigated the effects of supplementing medium with novel flavonoid-enriched antioxidant nanoformulations, namely, EMD-300® and EMP3-H200®, on oocyte analyzed expression stress, apoptosis, pluripotency genes buffalo. Cumulus complexes (COCs) obtained from buffalo ovaries were matured supplemented either or EMP3-H200® at 0.5% 1.0% for 22 h. Following...

Oocyte cryopreservation is valuable way of preserving the female germ line. Vitrification immature ovine oocytes decreased levels both maturation promoting factor (MPF) and mitogen-activated protein kinase (MAPK) in metaphase II (MII) after IVM. Our aims were 1) to evaluate effects vitrification GV-oocytes on spindle assembly, MPF/MAP kinases activities, preimplantation development following IVM IVF, 2) elucidate impact caffeine supplementation during quality vitrified/warmed GV-oocytes....

Camels (416 pregnant, 118 non-involuted post partum and 730 non-pregnant) were examined mortem. Large follicles (greater than 10 mm), small (5-10 mm) non-functional ovaries observed in 144 (20.7%), 127 (18.3%) 424 (61.0%) respectively out of 695 normal non-pregnant organs. Season did not exert any significant influence on the frequency these groups. Recently formed regressing CL after sterile mating occasionally seen. Corpora albicantia (3-15 most frequent structures organs parous camels as...

Summary The penis and prepuce of 14 mature camels aged 5 to 15 years were examined. Serial sections in the root, body free end made illustrate morphology this organ. It is suggested that type camel an intermediate form between cavernous fibroelastic varieties. Histological examination a cross-section glans revealed presence complete ring cartilage. Zusammenfassung Der Penis und das Präputium des einhöckerigen Kamels (Camelus dromedarius) von erwachsenen Kamelen im Alter 5–15 Jahren wurden...

Contents The reproductive records of 256 Arabian mares between 1922 and 1982 inclusive were analysed. length gestation (mean 332.1 ± 3.3 days, range 300–371 days) was significantly influenced by month foaling (p < 0.01), but not sequence or sex the foal. average interval to foal heat 7.6 0.1 days. Most periods (76.3%) occurred 6 8 days after foaling. Foaling rate higher 0.05) for bred on 9–11 (44%) than those 5–8 (33%) post‐foaling. Oestrus throughout year less frequent in summer spring...

Various techniques such as AI and ET have been reported to improve reproductive efficiency genetic potential in camelids. In vitro fertilization the development of IVP embryos are considered an alternative for improvement this species. This study investigated effects different sperm cell concentrations (1, 2, 3 4 × 106 mL–1), capacitating materials (5 mM caffeine, 10 μg mL–1 heparin, mg theophylline, 1 calcium ionophore A23178 heparin + 5 caffeine), post-slaughter epididymal flushing time...

Contents: Post‐mortem examination of 1048 nonpregnant genital organs female camels revealed gross abnormalities in 22 (2.1%). Ovarian included bilateral hypoplasia (0.1%), ovarian teratomas (0.4%) and follicular cysts (0.9%). Segmental aplasia the cervix with cystic dilation uterine horns was noted 8 specimens (0.8%). Out 467 pregnant examined left hydrosalpinx observed one organ . Inhalt: Genitale Anomalien beim weiblichen Dromedar (camelus dromedarius). Eine Schlachthofstudie Bei einer...

Contents: The current study was conducted on the accessory genital glands of 117 mature (4.5 to over 15 years) one‐humped male camels collected from main Cairo abattoir a peroid one year. weight showed consistent increase with age up 10.5–15 years, where maximum 4.24, 16.07 and 4.90 gm for ampullae, prostate bulbo‐urethral galnds recorded. overall average weights were 3.85,14.12 4.49 these respectively. On other hand, seasonal variations in highly significant (P < 0.01) ampullae 0.05)...

Vitrification of immature oocytes at the germinal vesicle (GV) stage is important to preserve female gametes. The standard formula for vitrification solutions has long been a debate. Herein, we investigated effect presence or absence trehalose in solution on viability, vitro maturation (IVM) rates, and development vitrified/warmed dromedary camel oocytes. Cumulus oocyte complexes (COCs) obtained slaughter from ovaries mature she-camels were randomly allocated into three groups; namely,...
