The aim of this study was to evaluate conception rate after sex determination and subsequent freezing of Day 7 (D7) bovine embryos and to compare it with transfer of fresh female embryos. High quality embryos obtained from superovulated donors were biopsied and the embryonic cells (5-10) were analysed by PCR using specific primers for the Y-chromosome determinant. Fresh embryos were blade biopsied (n = 172) and subsequently transferred (ET) ipsilaterally to synchronized recipients. Selected embryos (n= 112) were biopsied by cell aspiration and cryopreserved for later transfer. Sex determination was successfully completed in...

The aim of this study was to determine the most appropriate months for applying albendazole (ABZ; oral suspension dose 20 mg/kg body weight) to sheep naturally infected with Dicrocoelium dendriticum and kept at pasture, in order to reduce parasite egg shedding to a minimum, mainly during the cold months and, as a result, decrease pasture contamination by viable eggs. Five animal groups (G), homogeneous as regards the number of eggs per gram (EPG) in faeces, were established. The treatment months were: G1, November and January; G2, November and February; G3, November and April; G4, January; and G5 (control), April. Ten samplings (S1-S10) were...

Anatomical variations of the thoracic duct course are common in humans and domestic animals. They are important in thoracic surgery and in application of surgical techniques in experimental animals. The pig is a frequently used animal model due to numerous similarities between human and porcine anatomy and physiology. We revealed the position of the cisterna chyli, and the origin, course and termination of the thoracic duct by fine dissection on fifteen Yorkshire pig carcasses. The pigs were 2.5 months old with a body mass range from 10 to 15 kg. In this study we present our macroscopic observations. The cisterna chyli and thoracic duct had a common...

A case of intramedullary ependymoma in a young dog is reported. A two year old dog was presented with paralysis of the forelimbs. At myelographic examination, an intramedullary pattern, blocking the progression of contrast medium, was observed. At necropsy, a 3 × 2 cm white-greyish mass was found extending from the 3rd to 5th lumbar levels. At cytological and histological examination, the mass was highly cellular and was comprised of ovoid cells with indistinct borders, elongated eosinophilic cytoplasm and round to oval vesicular nuclei. Cytoplasmic processes formed a fibrillar network wherein true rosettes and many pseudorosettes...
Bone-conducted brainstem auditory evoked response in a dog with total bilateral ear canal ablation: a case report

The bone-conducted brainstem auditory evoked response test was performed in an eight-year-old dog with total bilateral ear canal ablation. It was found that 12 months after bilateral surgical ablation of the external acoustic meatus the dog still maintained its hearing function due to the mechanism of acoustic bone conduction.
