One hundred and fifty goats were diagnosed as having proven gangrenous mastitis. The disease was categorized into early, intermediate and late stages. Gangrenous mastitis in goats is typified by a sudden onset, dark hyperemia, and edema with progressive discoloration of the distal part of the udder. The disease affected lactating goats but not the dry ones. Coagulase positive Staphylococcus aureus was isolated from 60% of composite and half milk samples obtained from the diseased goats. The histopathological changes mainly comprised proliferation of connective tissue, thrombosis and necrosis involving a group of lobules. Treatment of the early and intermediate stages of the disease was successful through the administration of systemic and intramammary terramycin together with diuretics and topical antiseptic cream. The late stage of the disease was successfully treated only through surgery. 相似文献

The study was carried out in a flock consisting of 110 goats. Nine species of coccidia were found: Eimeria christenseni, E. arloingi, E. jolchijev, E. ninakohlyakimovae, E. alijevi, E. apsheronica, E. caprina, E. caprovina and E. hirci. Eighty-one percent of adults and 100% of kids were infected. Number of oocysts per gram of feces in kids ranged form 1200 to 202000. Clinical symptoms in about 50% of kids were observed. Toltrazuril (Baycox, Bayer), 20 mg/kg of body weight was highly efficacious in therapy of goat coccidiosis. 相似文献

The development of a dog:goat species of Sarcocystis was studied experimentally in goats. Schizogony in vascular endothelium at 18 and 19 days after infection was associated with-pyrexia, anaemia, anorexia, depression and death. Clinical signswere dose-related and doses of 6 × 105 or more sporocysts were fatal. Muscle invasion took place before 34 days. At 129 days, sarcocysts were infective for dogs and the life cycle was completed. Sporocysts of this dog:goat species were not infective for sheep. 相似文献

复合营养舔砖对马头山羊饲用效果研究 总被引：2，自引：0，他引：2
在马头山羊中心产区选择７个试验点共４５个试验场（户）的２６９５只马头山羊进行了复合营养舔砖的补饲试验，结果表明，补饲了复合营养舔砖的羊，毛色和膘情较对照组明显改观，增重速度比对照组提高３８．２９％（Ｐ〈０．０１），平均每只试验羊每天比对照羊净增纯收入０．１５２元，每吨舔砖可产生直接经济效益２．４万元。 相似文献

The epidemiology of trypanosomiasis in a tsetse-infested range area of Kenya was studied for 2 years in various breeds of sheep and goats. Observations, including infection rates, PCV, temperature and weight loss indicated that the exotic breeds were more susceptible to natural trypanosomal infection than the indigenous breeds and that the infection may be severely debilitating and in many cases fatal. Observations of tsetse numbers and rainfall in the grazing area during the first year showed that there was a significant correlation between tsetse numbers and rainfall of the previous month. The increase in tsetse numbers, which occurred one month after substantial rainfall, was followed by an increase in the prevalence of trypanosomiasis in the animals. However, during the second year when rainfall was low there was no correlation between tsetse numbers and rainfall. It was concluded that the seasonal incidence of trypanosomiasis and the possible trypanotolerance of the indigenous breeds are important factors to be considered when initiating a small stock improvement programme for trypanosomiasis-endemic areas. 相似文献

Results of blood coagulation and hematologic studies on 6 goats, each tested 3 times, were compared to the values seen in persons. Special blood platelet studies were done on an additional goat. Blood coagulation values in the goats and in persons were similar, with these exceptions: In the goat, activated partial thromboplastin time was shorter and thrombin time was longer; one-stage assays of factors V, VIII, and IX were very high, and platelets aggregated poorly epinephrine and ristocetin. Both platelets and erythrocytes were small. On scanning electron microscopy, the erythrocytes appeared as flat disks or triangles, occasionally having a dimpled center, compared to the deeply dimpled doughnut shape of the larger human erythrocytes. Osmotic fragility of these small erythrocytes was greater than that of their human counterparts. By transmission electron microscopy of ultrathin sections of goat buffy coat, platelets had fine structures similar to those of human platelets. Unlike in human platelets, most of the dense bodies in goat platelets were surrounded by clear vacuoles. Biochemical studies showed higher than human levels of phosphorus, chloride, sodium, alkaline phosphatase, and serum glutamic oxaloacetic transaminase. 相似文献
