Abstract

AIM

To establish the prevalence and factors influencing the prevalence and severity of gastric ulceration in racehorses in New Zealand.

METHODS

Horses (n=171) in active training for racing by trainers (n=24) located throughout New Zealand were examined using gastroscopy during 2003 and 2004. Images of the examination were recorded and reviewed, and an ordinal grade based on the severity of gastric ulceration present was assigned, using the grading system proposed by the Equine Gastric Ulcer Council (EGUC). Information about the horses such as age, breed, sex, stabling, time at pasture, pasture quality, and presence of clinical signs consistent with equine gastric ulcer syndrome (EGUS) was recorded.

RESULTS

Of the 171 horses in the study, 133 (78%) were Thoroughbreds and 38 (22%) were Standardbreds. Evidence of gastric ulceration was present in 151 (88.3%) of these. Prevalence of ulceration was higher at the lesser curvature (LC) and greater curvature (GC) of the stomach than at the saccus caecus (SC; p<0.01), and ulceration was more severe at the LC than at either the GC (p=0.02) or the SC (p<0.001). The prevalence of ulceration did not differ between the two breeds (p=0.51) or between horses of differing ages (p=0.56). Gastric ulceration was evident in 125/141 (89%) horses kept at pasture for at least 4 h/day, in all 13 (100%) horses kept at pasture full time, and in 16/17 (94%) horses stabled full time. Prevalence and severity of ulceration did not differ between horses stabled full time, kept at pasture for part of the day or kept at pasture full time (p=0.33 and 0.13, respectively), and for horses grazed on pasture severity of ulceration did not vary significantly with the quality of the pasture (p=0.12). Neither prevalence (p=0.26) nor severity (p=0.49) of gastric ulceration varied significantly with duration of training.

CONCLUSIONS

The prevalence of gastric ulceration in racehorses in New Zealand is similar to that reported elsewhere for horses in active training for racing. Access to pasture for some or all of the day did not appear to be protective.

摘要

目的

确定新西兰赛马胃溃疡的患病率以及影响其患病率和严重程度的因素。

方法

2003年至2004年期间，对新西兰各地24名驯马师训练的171匹现役赛马进行了胃镜检查。记录并复查检查图像，根据存在的胃溃疡严重程度，采用马胃溃疡委员会（EGUC）提出的分级系统进行分级。记录有关马匹的信息，如年龄、品种、性别、厩养情况、在牧场的时间、牧场质量以及是否存在与马胃溃疡综合征（EGUS）一致的临床症状。

结果

研究中的171匹马中，133匹（78%）为纯种马，38匹（22%）为标准马。其中151匹（88.3%）有胃溃疡迹象。胃小弯（LC）和胃大弯（GC）处的溃疡患病率高于盲囊（SC）处（p<0.01），且LC处的溃疡比GC处（p=0.02）或SC处（p<0.001）更严重。两个品种之间的溃疡患病率无差异（p=0.51），不同年龄的马之间也无差异（p=0.56）。每天在牧场至少停留4小时的141匹马中有125匹（89%）、全天都在牧场的13匹马全部（100%）以及全天厩养的17匹马中有16匹（94%）有明显的胃溃疡。全天厩养、部分时间在牧场或全天在牧场的马之间，溃疡的患病率和严重程度无差异（分别为p=0.33和0.13），在牧场放牧的马，溃疡严重程度与牧场质量无显著差异（p=0.12）。胃溃疡的患病率（p=0.26）和严重程度（p=0.49）均与训练时长无显著差异。
