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

Chinese horse industry is in the early stage of transition from traditional horse industry to modern horse industry. Scientific feed formula is of great practical significance to the development of modern horse industry. In this paper, the horse feed formula model based on the goal programming was constructed by analyzing and researching the horse's daily nutrition demand and the component elements of feed formula model. The formula optimized the horse's various nutrients, including dry matter, digestible energy, crude protein, calcium and phosphorus, ensured that the number of nutrients, quality and the proportion of their daily needs, and took into account the cost of feed also. Two different types of horses, race horse and riding horse were used to describe the design process for horse feed formulations based on different feed standards, and the effectiveness of the feed formula model was verified at the same time. The study would provide some reference value for the study of horse feed formula model.  相似文献

A horse whose serum reacted equivocally in the agar gel immunodiffusion (AGID) test for equine infectious anemia was studied over a 3-year period. The horse remained afebrile and virus was detected in only 1 of 6 horse inoculation tests. The intensity of AGID test reactions increased temporarily following this evidence for virus. Although the AGID test reaction was equivocal and 5 of the 6 transmission attempts failed, the 1 successful transmission proved the horse was infected.  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

Nuclear scintigraphy was used to evaluate healing of third metacarpal bone (MC III) fractures in 2 horses (horses 1 and 2) and a third metatarsal bone fracture in 1 horse (horse 3) after stabilization of each fracture with 2 broad dynamic compression plates. In horse 1, the fracture had uniform uptake of 99mTc methylene diphosphonate on days 1, 15, and 30 after surgery. The fracture healed, and the horse was discharged from the clinic on day 52. In horse 2, a 6-cm photopenic region (ie, area of low radioactivity) was seen over the diaphysis of MC III on day 3. The region persisted and became more distinct by day 32. The diaphysis of MC III sequestered, and horse 2 was euthanatized on day 44. In horse 3, vascularity was seen bridging the fracture on day 5, with a 3-cm photopenic region over the dorsal diaphysis of the third metatarsal bone. By days 18 and 32, uptake of 99mTc methylene diphosphonate in the region had increased, indicating vascularization of the site. the fracture healed, and horse 3 was discharged from the clinic on day 47. Our findings indicated that serial nuclear scintigraphy can be used to evaluate fracture vascularization after surgery in horses.  相似文献

Serological survey of Rhodococcus equi infection in horses in Hokkaido was performed using ELISA. Of 2,879 horse sera, 318 (11.0%) gave antibody-positive (OD greater than or equal to 0.3) reactions. The antibody-positive rate of female was significantly higher (p less than 0.01) than that of male, and no statistical difference between Anglo-Arab and thoroughbred was detected in the antibody-positive rate. The maximum antibody-positive rate (27.1%) was shown at 14 years of age. The antibody-positive rates on the 160 farms were found to vary widely from 0 to 78.9%. A significant difference (p less than 0.01) in the antibody-positive rate was detected among horse farms. It was elucidated that 100 (62.5%) out of 160 horse farms had an antibody-positive horse. These results indicate that R. equi was widespread on horse farms, and the level of environmental contamination with R. equi differed among horse farms.  相似文献

The sudden death of two horses was attributed to the rapid and acute development of pulmonary aspergillosis. One horse was making excellent postoperative progress after a jejunal resection and anastomosis for intestinal adhesions. The other horse was being treated routinely for equine protozoal myeloencephalitis (EPM). Signs of fever and an increased respiratory rate were detected shortly before death in the first horse, but no premonitory clinical signs characteristic of pulmonary infection were detected in the horse being treated for EPM. Both horses developed rapidly debilitating, acute pulmonary mycosis and died unexpectedly.  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

Australia has the world's largest population of wild equids and equine influenza (EI) was confirmed on several properties in New South Wales (NSW) close to uncontrolled areas of land during the 2007 outbreak. Likelihood and risk management assessments were carried out to determine the risk of EI infection of the wild horse populations. The likelihood of spread to the wild horse population was determined to be extremely low, but the likelihood of spread from an established wild horse reservoir back to domestic horses was considered high. The most effective mechanism of control was determined to be prevention of the spread of EI into the wild horse population through a vaccination buffer zone between EI infection foci and known wild horse populations.  相似文献

In this study, a structured survey questionnaire was used to determine consumers' preferences and behavior with regard to horse meat at a horse meat restaurant located in Jeju, Korea, from October 1 to December 24, 2005. The questionnaire employed in this study consisted of 20 questions designed to characterize six general attributes: horse meat sensory property, physical appearance, health condition, origin, price, and other attributes. Of the 1370 questionnaires distributed, 1126 completed questionnaires were retained based on the completeness of the answers, representing an 82.2% response rate. Two issues were investigated that might facilitate the search for ways to improve horse meat production and marketing programs in Korea. The first step was to determine certain important factors, called principal components, which enabled the researchers to understand the needs of horse meat consumers via principal component analysis. The second step was to define consumer segments with regard to their preferences for horse meat, which was accomplished via cluster analysis. The results of the current study showed that health condition, price, origin, and leanness were the most critical physical attributes affecting the preferences of horse meat consumers. Four segments of consumers, with different demands for horse meat attributes, were identified: origin‐sensitive consumers, price‐sensitive consumers, quality and safety‐sensitive consumers, and non‐specific consumers. Significant differences existed among segments of consumers in terms of age, nature of work, frequency of consumption, and general level of acceptability of horse meat.  相似文献

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

Encephalitis associated with Borrelia burgdorferi infection in a horse   总被引：1，自引：0，他引：1  
Infection with Borrelia burgdorferi was associated with encephalitis in a horse. The horse lived in an area of Wisconsin endemic for B burgdorferi infection. Borrelia burgdorferi was isolated from the brain, but rabies virus was not detected in the brain. Serum obtained from the horse had a B burgdorferi antibody titer of 1:2,048, but was negative for antibodies to eastern and western encephalomyelitis.  相似文献

Intramuscular desmoid tumors (musculoaponeurotic fibromatosis) were discovered in two young adult horses. The tumor in one horse was in the lateral cervical musculature, and that in the second horse occurred in the pectoral musculature. Histopathologic features were similar in both horses and included proliferation of fibroblasts and cells expressing muscle actin (myofibroblasts), with extensive dissecting fibrosis within muscle. These features are similar to those of desmoid tumors in humans, particularly those also known as musculoaponeurotic fibromatosis. Dissection of these lesions revealed a single central (horse No. 1) or multiple central (horse No. 2) fluid-filled cavities with associated sterile inflammation. The presence of these cavities supports the hypothesis that equine desmoid tumors are traumatic in origin, possibly occurring at sites of injections or bursal rupture. Surgical excision of the tumor in horse No. 1 was apparently curative, but the extent of the tumor in horse No. 2 precluded surgical excision.  相似文献

Chronic lymphocytic leukemia (CLL) was diagnosed in two horses: an 18-year-old Quarter Horse gelding that was examined because of edema of the prepuce and ventral abdomen; and a 20-year-old mixed breed gelding that was referred because of lymphocytosis, ventral edema, and weight loss. The first horse had enlarged peripheral lymph nodes and cool nonpainful pitting edema of the ventral abdomen and prepuce. The second horse had enlarged peripheral lymph nodes, cool nonpainful pitting edema of the ventral thorax and cranial ventral abdomen, and a 3/5 holosystolic heart murmur. The diagnosis of CLL was based on increased blood lymphocyte counts and infiltration of marrow and other tissues by lymphocytes. In horse 1, the lymphocytosis persisted for 2 months between initial examination and death. The results of flow cytometric analysis on blood lymphocytes using anti-lymphocyte antibodies suggested that horse 1 had T-cell CLL, and horse 2 had B-cell CLL. In addition, the second horse had a monoclonal gammopathy (IgG), with light-chain proteinuria.  相似文献
