<正>目前,肉用犬在我国的饲养越来越普遍,所用公犬大多数为体型较大的圣伯纳犬、藏獒、高加索犬等品种。由于公母犬之间体型差异太大,以及犬择偶性较强,影响了肉用犬的繁殖。为了提高肉用犬的受胎率和繁殖率,笔者进行了36例犬的人工授精试验, 相似文献

獒本杂交犬繁育性能研究 总被引：1，自引：1，他引：0
通过对獒本杂交犬与当地土种犬发情时间、配种时间、产活仔数、幼犬初生重等的对比研究,发现獒本杂交犬发情时间集中在9~11月份,发情受胎率与母犬年龄及养殖条件有关,常规养殖下3~4岁獒本杂交母犬发情率为100%,2~4岁獒本杂交母犬受胎率达到100%。獒本杂交犬产仔力和哺乳性能等繁育性能指标明显高于本地土种犬,1~5岁龄杂交母犬的平均活产仔数显著高于当地土种犬(P(0.05);仔犬平均初生重显著高于当地土种犬(P(0.05);仔犬断奶平均个体体重显著高于当地土种犬(P(0.01);仔犬断奶平均窝重显著高于当地土种犬(P(0.05);幼犬断奶成活数比土种犬高14.3%。 相似文献

Osteosarcoma of the patella was diagnosed by biopsy in a 9-year-old, male dog of mixed breeding. The dog was originally examined because of intermittent lameness of the left hindlimb; there were minimal palpable abnormalities of the stifle. After the diagnosis, the owner refused further treatment for the dog. The dog was reexamined 13 months later because of a marked swelling of the stifle. The dog was euthanatized and necropsy findings confirmed the diagnosis. 相似文献

A 9-year-old golden retriever dog was evaluated for polyuria, polydipsia, weight loss, and elevated serum thyroxine. Targeted questioning revealed that the dog was coprophagic and routinely ingested the feces of a dog that was treated with twice-daily levothyroxine. Clinical signs resolved and serum thyroxine decreased to normal levels in the affected dog with prevention of coprophagy. 相似文献

Exposure to marijuana was believed to be responsible for clinical signs consistent with allergic inhalant dermatitis in a dog. The dog had facial and pedal pruritus associated with bilateral ocular discharge. Clinical signs resolved when the dog was kenneled, but returned when the dog was returned to its home. The results of intradermal skin testing, using a standard tray of 51 inhalant extracts, did not adequately account for the dog's clinical signs. Later, the owners indicated that previous residents of the owners' home had cultivated marijuana intensively inside and outside of the home. Intradermal skin testing with a source of marijuana pollen extract was performed, yielding a positive reaction in the dog and a negative reaction in another dog without clinical or historical evidence of allergic inhalant dermatitis. The affected dog was treated successfully and exclusively by hyposensitization with marijuana pollen extract. 相似文献

In most European countries, registration and identification of dogs is compulsory. In Italy, the national dog registry is composed of regional dog registries. Although dog registries have been established for many years, the issue related to completeness of data has not been addressed so far. The objective of this study was twofold: first to assess the completeness of data of the dog registry through telephone interview of a sample of dog owners drawn from the dog registry, then to estimate the total owned dog population in 4 boroughs of Rome. For the second objective, a capture–recapture method was applied using data from the dog registry and data from a face-to-face questionnaire submitted to people waiting in the sitting room of 5 points of access for booking and payment of primary and specialist care. Different scenarios are proposed to verify the assumptions of the estimation procedure and potential biases are discussed. The completeness of data of the dog registry was 88.9% (95% CI: 85.8–91.9%) and the owned-dog population was estimated at 26,244 dogs (95% CI: 24,110–28,383). The dog registry is an important source of information especially when it is properly updated and completeness of data is known. 相似文献

通过提取猪、犬旋毛虫成虫抗原，制备成虫油佐剂免疫原，在小鼠体内进行同源特异性免疫试验和交叉免疫试验。试验得到猪旋毛虫成虫抗原同源免疫减虫率为５５．８０％，其对犬旋毛虫的交叉免疫减虫率是３５．１１％；犬旋毛虫成虫抗原同源免疫的减虫率为３９．００％，其对猪旋毛虫的交叉免疫减虫率是２４．９６％。试验结果揭示，猪、犬旋毛虫成虫具有一定的免疫原性，其交叉免疫减虫率低于同源特异性免疫。猪旋毛虫成虫抗原对犬旋毛虫的交叉免疫与犬旋毛虫自身的同源特异性免疫差异不显著。 相似文献

Intestinal malabsorption and cryptosporidiosis in an adult dog 总被引：2，自引：0，他引：2
C E Greene G J Jacobs D Prickett 《Journal of the American Veterinary Medical Association》1990,197(3):365-367
Chronic intestinal cryptosporidiosis was diagnosed as the cause of chronic diarrhea and weight loss in an adult dog without obvious signs of immunosuppression. Results of tests for digestive function suggested that the dog had impaired intestinal absorption or bacterial overgrowth. The nutrient malabsorption might have resulted in or have been caused by the cryptosporidiosis. Temporary clinical improvement without reduction in fecal oocyst concentration was noticed following treatment with clindamycin. The dog was euthanatized. At necropsy, the dog was found to have chronic lymphoplasmacytic enteritis and cryptosporidiosis. A veterinary student that worked in the ward where the dog was kept developed cryptosporidal diarrhea. 相似文献

Chylous ascites was diagnosed in 3 dogs. Mesenteric lymphangiography was performed in 2 dogs and helped delineate abnormalities of the lymphatic system. The cause of chylous ascites in each dog appeared to be different. In 1 dog, a ruptured mesenteric lymphatic was identified at surgery. Evidence of abdominal lymphatic obstruction was found in another dog. Chylous ascites in the third dog appeared to be a complication of mesenteric lymphangiography for chylothorax. 相似文献
