纳米蒙脱石在乳仔猪养殖中的应用 总被引：3，自引：0，他引：3
蒙脱石在乳仔猪的养殖中的应用越来越广泛，如治疗乳仔猪腹泻、代替氧化锌抗腹泻、仔猪护理、饲料脱霉和脱重金属。纳米蒙脱石对乳仔猪的腹泻有明显的治疗和控制作用，尤其对乳仔猪的红痢、黄痢、白痢等效果突出，可以完全替代氧化锌等高锌高铜添加剂，彻底解决饲料高锌高铜问题；纳米蒙脱石还可以用于仔猪护理，对皮肤、消化道及呼吸系统等无毒、无害、无刺激性，如涂抹在脐带还可使脐带迅速干燥，在去势、断尾后直接涂于伤口，可有效地消毒、止血；纳米蒙脱石添加到饲料中可对饲料中黄曲霉毒素B1等有害霉菌有明显的吸附脱出作用。 相似文献

药物饲料的现状和应用无抗生素饲料控制仔猪腹泻 总被引：1，自引：0，他引：1
由于具有防病、治病、促进动物生长、提高饲料转化率等功效，抗生素作为饲料添加剂在畜禽养殖业生产中被普遍使用。然而部分养殖企业不遵守抗生素使用的有关规定，抗生素持续使用使病原茵产生较强的耐药性，不但危害人民的身体健康，而且还影响养殖业的健康发展。无抗生素饲料可从仔猪营养方面着手，通过添加柠檬酸、酶制剂、益生素、氧化锌、纳米蒙脱石等措施控制仔猪腹泻。 相似文献

仔猪腹泻(Piglet diarrhea)又称仔猪拉稀或仔猪下痢,是养猪生产中最常见的问题,不管在集约化大型养猪场还是小型养猪专业户都普遍存在。仔猪腹泻可导致仔猪生长发育受阻、死亡率增加、饲料报酬降低等,给养猪生产带来巨大的经济损失。引起仔猪腹泻的病因主要有传染性因素和非传染性因素。本文主要对仔猪腹泻的防治措施进行了概括和分析,希望对仔猪腹泻的防治有所帮助。 相似文献

Companion animal rehabilitation, a collaborative practice of physical therapy and veterinary medicine, can only demonstrate the effectiveness of its theories, techniques, interventions, and modalities through evidence-based practice, utilizing standardized, reliable, and valid outcome measures, correlated with objective diagnostic data. This essay examines existing and potential objective outcome measures utilized in companion animal rehabilitation and physical therapy regarding pain, vital signs, body condition and composition, range of motion, muscle strength, inflammation, functional mobility, and gait. Discussion is included of the traditional disablement model and the evolution of the physical therapy diagnosis, prognosis, and plan of care. 相似文献

Chemistry tests were conducted on serum from young Beagle dogs in order to deter mine the effect of age on these parameters. Blood was collected at regular intervals from 25 normal Beagle puppies (13 males and 12 females) at ages ranging from 2 weeks to 12 months. Serum chemistry profiles, protein electrophoresis and radioimmunoassays for thyroxine and triiodothyronine were included. Rapidly changing age related differences were observed in several parameters. Urea nitrogen, cholesterol, triglycerides, lactate dehydrogenase, thyroxine, glucose, gamma glutamyl transpeptidase, and total bilirubin values were elevated early in life, and decreased during the first 6 to 8 weeks, while alanine aminotransferase activity was low initially and increased during this period. Lactate dehydrogenase, thyroxine, gamma glutamyl transpeptidase, total bilirubin and alanine aminotransferase attained stability by 3 months, but the remaining parameters showed slight changes subsequently, gradually approaching adult values. More gradual age related changes were observed in other parameters. These included alkaline phosphatase, inorganic phosphorus and calcium values, which were higher in younger dogs, and creatinine, aspartate aminotransferase and total protein values, which were lower in younger dogs. Creatinine and aspartate aminotransferase values were stable by approximately 6 months; alkaline phosphatase, inorganic phosphorus, calcium and total protein values continued to change gradually up to 1 year. 相似文献

OBJECTIVE: To determine the changes in Ca, P, Mg, Na, K, S, Cu, Fe and Zn concentrations of milk during the lactation in pasture-fed Thoroughbred mares and then calculate the dietary mineral requirements of the sucking foal and the lactating mare. PROCEDURE: Milk was sampled on days 1, 3, 7, 14, 21, 28 and at various times between 55 to 65, 85 to 95 and 135 to 150 days after parturition from 21 pasture-fed mares. The concentrations of macro- and micro-elements in the milk were determined by inductively coupled plasma emission spectrometry. RESULTS: Concentrations (mg/L) of these elements were highest in colostrum (Mg 302, Na 561, K 955, S 1035, Cu 0.76, Fe 0.79 and Zn 5.5) except for Ca (1245) and P (895), which where highest on day 7. The mean milk mineral element concentrations (mg/L) over days 55 to 150 were Ca 843, P 543, Mg 47, Na 120, K 590, S 219, Cu 0.19, Fe 0.34 and Zn 2.1. The mean plasma element concentrations (mg/L) over the same period were Ca 120, P 77.1, Mg 17.0, Na 3110, K 168, S 983, Cu 1.1, Fe 1.5 and Zn 0.49. Concentration gradients between plasma and milk were observed and, in the case of Ca, P, Mg, K and Zn, their concentrations in milk were greater than those in plasma, while a reverse situation was observed for Na, S, Cu and Fe. CONCLUSION: With the exception of Ca and P, the highest concentrations of mineral elements were observed in the colostrum. The nursing foal should have access to good pasture or creep feed, because the intakes of Ca, P and Cu from milk may be less than optimum to meet the daily mineral element requirements. 相似文献

Reference values were established for some haematological and serum biochemical constituents in Bactrian camels (Camelus bactrianus) in China. The contents of seven trace elements in the blood, hair, liver, kidney, heart, spleen, lung, cerebrum, cerebellum, rib, ovary, pancreas and gluteal muscle of Bactrian camels were also measured. Some of these values are reported for the first time for Bactrian camels in China. Most haematological and serum biochemical values were similar to those of cattle, yaks, sheep and dromedary camels, but the mean serum albumin concentration and the albumim/globulin ratio were significantly higher than those in other ruminants and the mean thyroxine concentration was half that in dromedary camels. The liver contained the highest concentrations of copper, zinc, manganese and iron, and the renal cortex contained the highest concentration of selenium. The concentrations of selenium, cobalt, zinc, manganese and molybdenum in the tissues were within the reference ranges for other ruminants, but the mean iron and copper concentrations in the liver were significantly higher than those in other ruminants. 相似文献

Radiographs of the stifles of 6 species of 34 large, non-domestic cats were reviewed foremost for the presence of meniscal ossicles and then for the presence of the other potential four sesamoids. The animals in the review included 12 lions, 7 tigers, 7 cougars, 3 leopards, 3 bobcats, and 2 jaguars. Fluoroscopy, arthrography, computed tomography, necropsy, and histology were also used to evaluate the stifles of one tiger after euthanasia. Ossicles were found in the region of the cranial horn of the medial meniscus in most of the lions, tigers, leopards, and jaguars. These ossicles were found in half of the cougars but in none of the bobcats. Among the large, non-domestic cats, meniscal ossicles had been reported previously only in Bengal tigers. The lions, tigers, and leopards having meniscal ossicles appeared to have a lateral but often not a medial fabella of the gastrocnemius muscle, an observation previously unreported. Popliteal sesamoids and patellas were present in all the skeletally mature cats. 相似文献

肉仔鸡可消化色氨酸需求参数研究 总被引：6，自引：0，他引：6
通过研究日粮中色氨酸水平对肉仔鸡生长性能、氮平衡及血清尿素氮含量的影响，探讨不同生长阶段不同性别肉仔鸡色氨酸的需求参数。试验期８周。结果表明：日粮中色氨酸达到适宜水平时，肉鸡的平均日增重增加（Ｐ＜０．０５）、料肉比降低（Ｐ＜０．０５）、血清尿素氮（ＢＵＮ）含量下降（Ｐ＜０．０５）；色氨酸水平过高则不能继续改善其生产性能，甚至造成负效应。在３～６周龄及６～８周龄阶段，公鸡色氨酸需求参数高于母鸡。日粮色氨酸水平对肉鸡的氮沉积率无显著影响（Ｐ＞０．０５），不同性别肉鸡的氮沉积率无显著差别（Ｐ＞０．０５）。根据各项指标的测定结果，建议在０～３周龄，肉鸡色氨酸需求参数为０．２１％；在３～６周龄，公鸡色氨酸需求参数为０．２０％，母鸡为０．１８％；在６～８周龄阶段，公鸡色氨酸需求参数为０．１８％，母鸡为０．１６％。采用去盲肠成年种公鸡测定基础日粮（玉米—玉米蛋白粉）中色氨酸的消化率，并计算出不同性别肉鸡可消化色氨酸需求参数。 相似文献
