ABDOMINAL ULTRASONOGRAPHY IN THE ADULT HORSE. LITERATURE REVIEW AND OWN EXPERIENCES. PART 2

The study describes the principles and methods of equine two-dimensional abdominal ultrasonography. Beside the review of the literature, the authors also present their own experiences. They demonstrate the imaging technique, physiological findings and the most important pathological alterations by using figures and ultrasonograms. In the first part they discuss the ultrasonography of the gastrointestinal tract. In the second part they present the examination of the spleen, liver, kidneys, bladder, peritoneum and other abdominal organs.

ROLE OF SCINTIGRAPHY IN DIAGNOSING ORTHOPAEDIC INJURIES IN HORSES. PART 1

Scintigraphy plays an important role in diagnosing orthopaedic injuries in horses. The aim of this article in two parts is to give an overview about the procedure of equine scintigraphic examination and explain the value of scintigraphy in lameness and poor performance investigations. In Part 1 principles of nuclear medicine, equipment and other requirements for equine scintigraphic examination, process of image acquisition and principles of radiation safety are reviewed. Image interpretation, orthopaedic indications and common normal and abnormal findings will be discussed in Part 2.

POSTOPERATIVE COMPLICATIONS OF EQUINE COLIC SURGERIES AND CASE REPORT

The authors shortly summarize the most common complications of equine colic surgeries, as well as their alternatives in the prevention and therapy. From the acute and chronic postoperative complications the authors review the complications of the surgical site, ileus, endotoxaemia, thrombophlebitis, septic peritonitis, colitis, laminitis and gastric ulceration. In the second part of the article the authors present the colic surgery of a 9 years old mare with right dorsal displacement of the large colon, an upcoming small intestinal ileus on the 8th day and its postoperative care.

EXAMINATION OF DIFFERENCES OF CERTAIN METABOLIC BLOOD PARAMETERS IN PREGNANT AND NONPREGNANT DAIRY COWS

The aim of the study was to examine the relationship between the metabolic blood parameters and the effectivity of the first postpartum insemination and the ovarian activity of non-pregnant cows. Holstein Fresian cows (n=79) were investigated between the day 90th and 120th after calving. Based on early pregnancy check, progesterone testing and ultrasonic examination, cows were divided into 4 groups: repeat breeder, pregnant, open cycling and open, inactive corpus luteum (CL). To monitor the metabolic status, the samples were assayed for the level of serum alpha-tocopherol, retinol and beta-carotene, and plasma concentrations of glucose, urea, uric acid, NEFA and beta-hydroxybutyrate (BHB). The concentration of alfa-tocoferol, beta-carotene and NEFA was found higher in the samples of the repeat breeder and the open, inactive CL groups. The plasma concentration of urea and uric acid was significantly lower in the open, inactive CL group than in the other three. Significant difference was found between BHB plasma level of pregnant and repeat breeder groups. The correlation between the different parameters was also examined. Significant correlation was found between the serum concentration of alfa-tocoferol and beta-carotene. Positive mild correlations were found between the serum/plasma level of retinol and urea; uric acid and beta-carotene; and BHB and urea. Negative correlation was observed between the concentration of beta-carotene and urea; beta-carotene and BHB; and urea and glucose. Although the differences were statistically significant, the authors did not found physiological relationship between the metabolic serum or plasma parameters and the effectivity of the first postpartum insemination and the ovarian activity of non pregnant cows at 90–120 days after insemination.

CRITICAL POINTS IN THE CRYOPRESERVATION OF STALLION SEMEN – PILOT STUDY

There are several different methods for the cryopreservation of stallion spermatozoa, however, a generally accepted technology with quality standards does not exist. The cryopreservation process should be flexible enough from the point of view of individual differences of the stallions. The aims of the present pilot study were to assess the spermiogram of the stallions that were chosen for further experiments to have a baseline information about their semen quality and freezability, moreover, to find the critical points of the currently applied cryopreservation protocol in order to plan future experiments. The ejaculates of four Shagya-Arabian stallions were investigated in three repetitions. The most critical points of the semen processing protocol were the centrifugation, the equilibration and the freezing-thawing steps. In their future experiments they intend to try such alternatives of these steps which are less harmful for stallion spermatozoa.
