The objective of the study was to evaluate the usefulness of haptoglobin (Hp) determination as an index in the monitoring of sheep welfare and health status in the pre- and post-slaughter period. The research results indicate a strict correlation between concentration of ovine serum haptoglobin and the presence and severity of pathological lesions visualised in the internal organs at the post-mortem examination. The Hp assay in live sheep prior to transportation to a slaughterhouse allows identifying the animals with subclinical infections. Thus, the Hp index may be used for an assessment into the state of the sheep's health in the pre-slaughter period by the veterinary inspection and as a safety measure of food of animal origin. Besides, a serum haptoglobin content established in sheep intended for slaughter may aid in the evaluation of the animal welfare at transportation and body condition after it as well as in the period following the 48 h rest time before slaughter.
Ultrasonography is a noninvasive diagnostic tool used to image size, shape, parenchyma and vascularization of various body organs. Unfortunately, the ultrasonographic image is characterized by a low contrast due to similar acoustic properties of the soft tissue. The Doppler mode provides information about blood flow, but is incapable of imaging small vessels and capillaries because of their low blood flow velocity (1 mm/s). However, a possibility to increase the effectiveness of ultrasonographic diagnostics exists, thanks to intravenous ultrasound contrast agents (UCAs) consisted of gas microbubbles. The purpose of this review paper is to characterize specific imaging techniques necessary to conduct a contrast-enhanced liver examination and indications for CEUS as an alternative diagnostic method.
Relative performance of students by gender in public examinations was assessed using questionnaires and standardized test on one hundred and eighty students from some selected urban centered schools in Benue State. Casual comparative design and correlation design were used and the results showed that socio-economic status of parents affects the performance of their children/wards (students), and there is no significance difference in the level of performance between boys and girls in public examinations. Parent should be enlightened through seminars and workshops on the importance of educating themselves and their children/ward. Governments, nongovernmental organization (NGO’S) and individuals should establish more schools for more education of both sexes. These were the suggestions advanced.
