Kisspeptin Receptor Agonist (Ftm080) Increased Plasma Concentrations Of Luteinizing Hormone In Anestrous Ewes, Brian K. Whitlock, Kelly A. Chameroy, Rebecca R. Payton, Shinya Oishi, Nobutaka Fujii, Joseph A. Daniel

Kisspeptin (KP) and the KP receptor (Kiss1r) are integral to central regulation of the gonadotropic-axis. The demonstration that intravenous infusion of KP can stimulate gonadotropin secretion and ovulation in seasonally anestrous female sheep offers a means of manipulating the reproductive axis. However, KP may be of limited clinical use because of the short circulating half-life. Kiss1r agonists with increased half-life and similar efficacy to KP in vitro potentially may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. This study was designed to test and compare the effects of …


Effect Of Different Transport Temperatures On In Vitro Maturation Of Oocytes Collected From Frozen-Thawed Sheep Ovaries, Özen Banu Özdaş, Alper Baran, Muzaffer Taş, Ümüt Ci̇ri̇t, Kamber Demi̇r, Süleyman Bacinoğlu, Serhat Pabuccuoğlu, Kemal Ak Jan 2013

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the effects of 2 different transport temperatures on the in vitro maturation of oocytes collected from frozen-thawed sheep ovaries. Sheep ovaries were transferred into saline at temperatures of 4 °C and 32 °C. After the 2 experimental groups (A: fresh cortex, B: frozen-thawed cortex) were formed, each group was divided into 2 subgroups (group A1: 4 °C, group A2: 32 °C [control]; group B1: 4 °C, group B2: 32 °C). The cortexes were dissected into slices 1-3 mm thick and pieces of 0.5 cm2. For groups B1 and B2, 1-2 cortex pieces …


The Effect Of Selenized Yeast Supplementation On Some Performance Parameters In Sheep, Bogumila Pilarczyk, Agnieszka Tomza-Marciniak, Zbigniew Dobrzanski, Malgorzata Szewczuk, Tomasz Stankiewicz, Dariusz Gaczarzewicz, Wlodzimierz Lachowski Jan 2013

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to determine the levels of serum selenium in coarse-haired Pomeranian sheep and to evaluate the effect of the oral supplementation of selenized yeast on selected performance parameters in such sheep. The sheep were divided into 2 groups, with 53 ewes forming the experimental group and 34 ewes forming the control group. The concentration of serum selenium in all 87 sheep from the 2 groups was analyzed. The sheep in the experimental group received selenized yeast for the 3 days before and 3 days after mating (1 g preparation/animal daily, with 1 g of preparation …

Scrapie Cases In The Northern Cyprus, Aydin Gürel, Ahmet Gülçubuk, Nuri̇ Turan, Christopher Richard Helps, Hüseyi̇n Yilmaz

Turkish Journal of Veterinary & Animal Sciences

Scrapie is a fatal neurodegenerative disease affecting small ruminants that causes economic losses in many countries. It is categorized together with other fatal neurodegenerative diseases as a transmissible spongiform encephalopathy. The aim of this study was to investigate clinical cases and the cause of death in a flock of sheep from Northern Cyprus (Turkish Republic of Northern Cyprus) suspected of having scrapie. Brains from 4 sheep showing clinical signs of classical scrapie, out of a flock of 200 animals, were analyzed by histopathological examination and infective prion enzyme-linked immunosorbent assay (ELISA). The 4 affected sheep were 2-3 years of age …


Presence Of Mycoplasmas In The Respiratory System Of Small Ruminants Managed Under An Extensive Production System, Zinka Maksimovic, Christian De La Fe, Maid Rifatbegovic Jan 2013

Presence Of Mycoplasmas In The Respiratory System Of Small Ruminants Managed Under An Extensive Production System, Zinka Maksimovic, Christian De La Fe, Maid Rifatbegovic

Turkish Journal of Veterinary & Animal Sciences

The objective of this study was to investigate the presence of mycoplasmas in the respiratory system of sheep and goat populations managed under extensive production systems. Specific culture and polymerase chain reaction techniques were performed on a total of 88 lung tissue samples and 142 nasal swabs obtained from multiple herds in Bosnia and Herzegovina. A total of 29 samples (12.6%) were found to be positive for mycoplasmas. Mycoplasma ovipneumoniae was detected in the nasal swabs and lungs of affected sheep (n = 19) and in the lungs of asymptomatic goat kids (n = 2), while M. arginini (n = …
