Systemic histiocytosis was diagnosed at post mortem examination in a three-year-old Bernese mountain dog born in the United Kingdom. The dog presented with a progressive nodular skin disease, chemosis and periocular swelling occurring over six months. It was unresponsive to topical corticosteroids, antibiotics and oral azathioprine. Elective euthanasia was performed. Post mortem examination revealed extensive histiocytic infiltration of the skin, subcutis and skeletal muscles, particularly of the head. 相似文献

Effect of monensin, estradiol controlled release implants and supplement on performance in grazing steers 总被引:1,自引:0,他引:1

Five trials in five locations in the United States involving 512 steers were conducted to evaluate the effect of monensin [200 mg/d in .9 kg of supplement (Ru mensin )] and estradiol-controlled release implants ( Compudose ) administered alone and in combination on average daily gain (ADG) in steers on pasture. The effect of energy supplementation on rate of gain was also evaluated in these same trials. The initial weight of steers averaged 250 kg and the average duration of the five trials was 124 d. Estradiol-controlled release implants increased ADG by 15.6% (.095 kg/d; P less than .0001) and monensin increased ADG by 8.1% (.054 kg/d; P less than .05). The combination of estradiol-controlled release implant and monensin increased ADG by 27.4% (.168 kg/d). Treatment responses were additive relative to ADG response, with no interaction observed between the treatments. Nine-tenths kilograms of an energy supplement/d increased ADG by 12.4% (.073 kg/d; P less than .01). 相似文献

Pony Club is one of the leading junior equestrian organisations in the world, and was established to teach young people the many aspects of horsemanship. The aim of this study was to gain an understanding of the health and performance of Pony Club horses from the perspective of their owners. In-depth interviews were conducted with Pony Club members at two sites in Australia, and topics relating to participants' background with horses, horse attributes valued by participants, horse health and performance, and Pony Club-related matters. The in-depth interviews were taped, transcribed and analysed, by describing the themes and issues recorded in the dialogue and conducting cross-case analysis (finding similarities and dissimilarities between participants with respect to each of the above-mentioned topics). A total of 32 interviews were conducted. The participants' background with horses varied greatly. The horse attributes valued by > or =59% of participants included temperament, size, ability and suitability for riders. A range of issues relating to health and performance were important to > or =53% of participants, including horse temperament, nutrition, internal parasites, lameness and foot-care, and colic. Soundness and preventive health measures were rarely mentioned (< or =16% of participants). Friends or knowledgeable horse people were identified as the first point of contact for horse-health matters, and veterinarians were only used as a last resort or for serious problems. Members of Pony Club learned about their horses by trial and error. Optimal performance was described as a horse that was willing to do as the rider asked. Poor performance was usually the result of the horse misbehaving, and could include a resistance to rider commands, pigrooting and bucking. 相似文献

Three 8-week-old kittens were presented with a history of acute, generalized weakness and severe fever. One cat was dead upon presentation, and necropsy findings were supportive of a group G Streptococcus spp. septicemia. During their clinical courses, two of the three kittens developed a progressive, marked swelling of one or more limbs. One moribund and severely hypothermic cat was euthanized a few hours after presentation, and necropsy was also supportive of a group G Streptococcus spp. septicemia. One kitten recovered. Group G streptococcal toxic shock-like syndrome was suspected because of the fulminant progression of the septicemia. 相似文献
