Haemonchus contortus provoca grandes prejuízos à ovinocultura. Visando reduzir a utilização de ovinos hospedeiros e produzir estágios parasitários em larga escala, um protocolo para o cultivo in vitro por 42 dias de larvas de terceiro estádio de H. contortus foi realizado em meio Eagle, modificado por Dulbecco (DMEM). No cultivo sem células, as lar...

Archived formalin fixed paraffin-embedded (FFPE) tissues are powerful tools in medicine, capable of harboring diagnostic and genetic answers to challenging clinical questions. Successful utilization of DNA derived from FFPE samples is dependent upon repairing DNA damage generated from the fixation process. Methods to repair FFPE DNA have been succe...

In this study, we aimed to position the Hungarian Merino among other Merino-derived sheep breeds, explore the characteristics of our sampled animals' genetic similarity network within the breed, and highlight single nucleotide polymorphisms (SNPs) associated with daily weight-gain. Hungarian Merino (n = 138) was genotyped on Ovine SNP50 Bead Chip (...
Vegetation management on solar farms can be accomplished through targeted grazing with sheep. To the authors’ knowledge, no research has been conducted to date on sheep grazing behavior on solar farms, yet such research is crucial to inform grazing management practices for contract grazers on solar farms. The objectives of this study were to invest...

To evaluate the molybdenum (Mo)-induced changes of intestinal morphology and the relationship of intestinal tight junction (TJ) proteins expression and intestinal barrier function, a total of 20 healthy sheep were randomly divided into five groups of four: 0, 5, 10, 20, and 50 mg/kg BW/day Na2MoO4·2H2O were administrated in five groups named contro...

The study aimed to detect Francisella tularensis (F. tularensis) in water samples and to investigate the seroreactivity of sheep to tularemia in endemic areas where human tularemia cases have been reported in Ankara, Turkey. For the isolation of F. tularensis, 50 water samples were collected from rural areas of 5 regions of Ankara (Turkey) and sele...

Respiratory sinus arrhythmia (RSA) provides a quantitative evaluation of 'vagal tone' and may be used for pain and stress assessment in livestock. The aim was to quantify the magnitude of RSA in cows and sheep. In 7 cows and 4 sheep standing at rest we measured the 3-lead electrocardiogram (ECG) together with the pneumogram, to identify inspiration...

This study investigated the effectiveness of different doses of estradiol benzoate (EB) to promote cervical relaxation and their effects on luteal function and outcomes of non-surgical embryo recovery (NSER) in sheep. Multiparous (MULT) and nulliparous (NULL) crossbred Lacaune X Santa Inês ewes were superovulated and naturally bred. Seven days afte...
The presented work deals with levels and distribution of bisphenol A (BPA) in the edible tissues of a large food-producing animal species. An experimental animal study included 14 young Istrian pramenka rams (Ovis aries), of which seven were exposed for 64 days to a low dietary dose of BPA at 25 µg/kg b.w./day, and seven served as a control group. ...

The agent of scrapie is resistant to most chemical and physical methods of inactivation. Prions bind to soils, metals, and various materials and persist in the environment confounding the control of prion diseases. Most methods of prion inactivation require severe conditions such as prolong exposure to sodium hypochlorite or autoclaving, which may ...
