This experiment was conducted to study the albumen quality of eggs from 60-wk-old hens fed 0 or 10 ppm supplemental vanadium (V) as influenced by storage conditions and length of storage time as well as the effect of V feeding and withdrawal on albumen quality over time. After hens were fed V for 23 d, eggs were collected and stored in the laying house at ambient temperature or in a cooler (15.5°C, 60% relative humidity) for 1, 3, 5, or 7 d. Eggs were then broken, and Haugh units (HU) were calculated. Hens fed V had poorer albumen quality than eggs from birds fed the control diet (62.5 vs. 72.1 HU, respectively). Eggs stored in the layer house had poorer albumen quality than those stored in the cooler (63.9 vs. 70.7 HU, respectively). Increasing storage time also had a detrimental effect on albumen quality. Quality declined more rapidly in eggs stored at ambient temperature than in the cooler, but it was not influenced by dietary V. Thus, there was no 3-way interaction as hypothesized.After 7 d of feeding hens 10 ppm V, their eggs had poorer albumen quality than eggs from hens fed the control diet. Time analysis indicated that the significant negative effect to albumen quality occurred in V-fed hens on d 1, 2, 5, and 12 of supplementation. When these hens were then switched to the control diet after 30 d of V supplementation, albumen quality continued to decline for 2 d but did not differ by d 6 from that of eggs from hens given the control diet. 相似文献

Objective: To provide information on the ingestion, and subsequent toxicity, of raw bread dough in dogs. Case summary: A report from the ASPCA animal poison control center (APCC) files of 3 cases of ingestion of raw bread dough by dogs. Clinical signs included vomiting, ataxia, blindness, hypothermia, and recumbency. All dogs were successfully treated for ethanol toxicosis. New information: Ingestion of bread dough can cause gastric obstruction, bloat, or ethanol toxicosis. The treatment of ethanol toxicosis, including decontamination, IV fluids, management of metabolic acidosis, and hypoglycemia is discussed. Yohimbine can be used in cases where the dog is comatose or has developed severe respiratory depression. 相似文献

William H. Adams DVM Robert L. Toal DVM MS Michael A. Breider DVM PhD 《Veterinary radiology & ultrasound》1991,32(2):60-62
A one year old female Siamese-Persian mixed breed cat in late third trimester of pregnancy was presented for anorexia and lethargy. Abdominal radiographs were normal. Abdominal ultrasound revealed markedly increased cortical and moderately increased medullary echogenicity of the maternal kidneys. Cortical echogenicity of all fetal kidneys were similarly increased in echogenicity. Premortem clinicopathologic and postmortem histopathologic findings were indicative of ethylene glycol nephrosis presumably secondary to antifreeze ingestion. 相似文献

A retrospective analysis of all adverse experience reports received by the Australian Pesticides and Veterinary Medicines Authority's Adverse Experience Reporting Program for veterinary medicines since 1995, showed that permethrin toxicity in cats usually occurred after the owner applied a canine permethrin-containing product, typically a spot-on. Cats are also at risk from grooming or being in direct contact with recently treated dogs. This paper reviews permethrin toxicosis and its treatment in cats, incorporating information from the Australian and selected overseas veterinary pharmacovigilance programs. 相似文献
