Ultrasonic Characteristics of Physiological Structures on Bovine Ovaries

摘要: The use of diagnostic ultrasonography in veterinary medicine general (23), and especially for the assessment bovine genital tract ovarian structures (7,6,13,22), is not yet widespread, but increasing rapidly. topography which cannot be visualized as easily as, example, mare, main reason why this technique so widespread cows. ovaries tips uterine horns are always easy to reach with ultrasound transducer via rectum, vagina or abdominal wall. Ultrasonography may necessary when rectal palpation well hormone analysis do give desired information about normal pathological activity. Visualization rectum can us extra follicle population, presence functional corpora lutea, follicular luteinized cysts, haematomas ovaries, responses hormonal treatment (1,25) abnormalities region. Other applications cows besides study include early pregnancy diagnosis (1,4,7,12,16,24,26), check age, sex and/or viability fetus, aspiration oocytes, so-called “ovum pick-up” (15). scanning reliability was first reported by Pierson et al. (11,13) Quirk (18). Changes growth patterns follicles aid (daily) have also been studied (22).
