It is well known that horse breeding in Bulgaria is a cultural heritage in Bulgaria, dating from prehistoric and historic times. Until now, molecular data on Bulgarian horses from the plain regions of the country were not available. Therefore, for the first time, we have collected genetic information about some modern horse breeds from the plain regions in Bulgaria. A total of 50 horses originating from different families from two different breeds were investigated: the first one was the Pleven horse (n = 11, breeding in the Danubian Plain), and the second one was the East Bulgarian horse breed (n = 39, Shumen district). These breeds were genotyped according to the mitochondrial D-loop region. The results showed that the Pleven horse particularly carries the European haplogroup L (45.45%), followed by the Middle East haplogroup C (27.27%). In contrast to the Pleven horse, the East Bulgarian horse breed revealed almost equal frequencies of the European specific haplogroup L (33.33%) and the Central Asiatic haplogroup Q (35.90%). Analyses of these two horse breeds revealed a specific genetic profile, but it is obvious that the East Bulgarian horse showed an unusual, mixed profile—a massive admixture with the Asiatic-type haplogroup Q and a high haplogroup diversity. In conclusion, the differences in genetic structure of the two plain horse breeds may be explained with the various horse breeds involved in their formation. 相似文献

OBJECTIVE: To evaluate risk factors associated with development of catheter-associated jugular thrombophlebitis in hospitalized horses. DESIGN: Retrospective case-control study. ANIMALS: 50 horses with thrombophlebitis and 100 control horses. PROCEDURE: Medical records from 1993 through 1998 were searched for horses with thrombophlebitis. Horses that were hospitalized for at least 5 days, had an i.v. catheter placed in a jugular vein (other than for solely anesthetic purposes), and had no evidence of thrombophlebitis during admission or hospitalization were chosen as controls. Signalment, history, clinicopathologic findings, primary illness, and treatment were obtained from the medical records. Data were analyzed by use of logistic regression to perform univariate and multivariate analyses. RESULTS: For a horse with endotoxemia, the odds of developing thrombophlebitis were 18 times those for a similar horse without endotoxemia. For a horse with salmonellosis, the odds of developing thrombophlebitis were 68 times those for a similar horse without salmonellosis. For a horse with hypoproteinemia, the odds of developing thrombophlebitis were almost 5 times those for a similar horse without hypoproteinemia. For a horse in the medicine section, the odds of developing thrombophlebitis were 16 times those for a similar horse in the surgery section. For a horse with large intestinal dise, the odds of developing thrombophlebitis were 4 times those for a similar horse without large intestinal disease. For a horse receiving antidiarrheal or antiulcerative medications, the odds of developing thrombophlebitis were 31 times those for a similar horse not receiving these medications. CONCLUSIONS AND CLINICAL RELEVANCE: Results indicated that patient factors, including large intestinal disease, hypoproteinemia, salmonellosis, and endotoxemia, were associated with development of catheter-associated thrombophlebitis in horses. 相似文献

Trials were performed to investigate in which way mechanical and/or thermal treatment of horse beans would have an effect on the harmful components that were shown to be present in horse beans. In the course of these trials amino acids from heat-treated horse beans (variety Fribo) were analyzed for their true digestibility. Apart from heat-treated horse beans the investigation included undecorticated and decorticated beans and a mixture of horse beans with spring barley. 相似文献

In mammal circulation, ferritin-binding proteins (FBPs) are thought to be involved in
clearance of circulating ferritin after complex formation with it through
receptor-mediated uptake. However, there is no report on fetal FBP in fetal circulation.
Although iron concentrations of fetal horse plasma were higher than those of adult horse
plasma, plasma ferritin concentrations and ferritin-binding activities were found to be
significantly lower in fetus than in adult. FBPs were purified from fetal or adult horse
plasma on horse spleen ferritin-Sepharose 4B affinity column. Partially affinity-purified
fetal horse plasma FBPs were mainly separated into 65 and 41 kDa bands in addition to
minor bands with higher molecular masses ranged from 102 to 140 kDa on SDS-PAGE under
reducing condition. The adult horse plasma FBPs were separated into 74, 54 and 28 kDa
bands, and the 74 and 54 kDa bands reacted with antibodies specific for horse IgM and IgG
heavy chains, respectively, by immunoblotting analyses. On the other hand, no antibodies
to horse immunoglobulin classes detected any bands in fetal horse plasma FBPs. The
affinity-purified adult and fetal horse plasma FBPs did not contain fibrinogen as a plasma
specific FBP, probably due to its lower affinity to the ligand ferritin. These results
demonstrate the presence of FBPs which are different from adult horse plasma FBPs
including anti-ferritin autoantibodies in fetal plasma. 相似文献

A horse was presented for soft palate thermocautery and surgical advancement of the larynx under general anaesthesia, following a history of respiratory noise and poor athletic performance. Physical examination prior to surgery was unremarkable. The horse was anaesthetised and a 20 mm cuffed endotracheal tube (ETT) used to intubate the trachea via the right nostril. The cuff was deflated at the end of the procedure and the tube secured in place around the head of the horse for the recovery. The horse was assisted to standing and during this process the end of the nasotracheal tube broke and was observed hanging from the head collar. The remainder of the tube was aspirated into the trachea of the horse. The remaining length of endotracheal tube was removed using a modified endoscopic technique. The horse recovered with no further problems. An unusual complication of a nasotracheal tube left in situ for recovery in a horse is reported and possible reasons for this complication are discussed. 相似文献

An acepromazine (ACP) hapten was synthesised, coupled to bovine serum albumin and injected into a horse to produce antibodies to the drug. A competitive ELISA was developed whereby ACP attached to the solid phase via lysozyme competed with free ACP present in phosphate buffered saline, horse serum or horse urine for limiting amounts of antibody. The assay could detect the presence of ACP and, or, some of its metabolites in horse urine for at least 25 hours after intravenous injection of 0.1 mg kg-1 ACP maleate, but because of non-specific interference, horse serum could not be used. As little as 0.24 micrograms ml-1 ACP or its metabolites could be detected. The level of detection and the ease of performance of the assay make it an attractive alternative to the more complex methods currently available for the screening of horse urine samples at horse races, shows and sales. 相似文献

Active skin tests were carried out on a horse with sweet itch using extracts of various biting insects and the resulting reactions compared with those produced when rabbit anti-human IgE was injected intradermally into a normal horse. The horse with sweet itch produced a large reaction to an extract of Culicoides which was similar to those produced by anti-human IgE. Absorption of serum from an allergic horse with anti-human IgE reduced its ability to sensitize skin of a normal horse to challenge with the extract of Culicoides. Passive transfer of allergic horse serum to guinea-pig skin gave significant reactions when challenged after a latent period of 4 h but not after 24 h. 相似文献

The practice of horse rugging has important implications for horse welfare and performance, but in Australia, rugging practices have not been properly documented. The objective of this study was to obtain an understanding of Australian horse rugging practices. An online survey reviewed the management of 2659 Australian horses over 12 months. Of the reported horses a total of 84.8% were rugged, although most owners (69.5%) indicated that they were unsure whether horses needed to be rugged at all. Rugging was felt by 59.8% of owners to be a requirement for horses in competition. Riding and competition were significantly associated with the use of rugs. Nearly all respondents (89.0%) felt that ‘over-rugging’ was a concern. However, 4.8% of owners would use up to 4 rugs at any one time on their horse and 21.4% of horses were still rugged in temperatures above 20°C in Australia. Many Australian horse owners (42.8%) also believe that horses feel cold if they are not rugged. Anthropomorphism when it comes to rugging horses cannot be justified as the horse has a much wider thermoneutral zone (TNZ) than humans. Australian climate, owner opinions, equestrian discipline and whether a horse is used for riding influence Australian horse rugging practices. However, current practices are based on limited available research and are not necessarily to the benefit of the horse. The major limitation was that the survey likely attracted respondents who are interested in the topic creating a self-selection bias. 相似文献

Factors to consider when deciding on a surgical approach to explore the abdomen of a horse include facilities and equipment available, experience of the surgeon, temperament of the horse and the necessity for cosmesis. An approach performed with the horse standing may be necessary when anaesthesia or recovery from anaesthesia is considered risky or when the owner imposes a financial limitation that does not allow surgery to be performed with the horse anaesthetised. Approaches performed with the horse standing include the flank and colpotomy approaches. Each approach has benefits and risks inherent to it. 相似文献
