临床上引起鸡眼炎的病因有多种，有细菌性的疾病，病毒病，也有营养缺乏病和氨气刺激及寄生虫病等。鸡眼炎的主要表现为眼结膜发炎，角膜发炎，角化或溃疡，眼睑和眼部肿胀，流浆液性、粘液性，甚至脓性分泌物乃至造成失明。现结合临床实践经验，将一些引起鸡眼炎的疾病介绍如下。1.传染性鼻炎：病原为副鸡嗜血杆菌，各种年龄的鸡均可感染。典型症状是初期流稀薄鼻液，逐渐浓稠，有臭味，变干后成为淡黄色鼻痂，附着于鼻孔内外，使呼吸不畅。眼结膜发炎，流泪，眼睑肿胀，脸和肉髯肿胀。剖检可见：鼻腔和窦急性卡他性炎症，粘膜充血，潮红肿… 相似文献

无论转山拜寺，都意在追求一种圆满。马年里，世上的所有神与仙都会聚集到冈仁波齐来，此时转山，不仅是朝拜冈仁波齐的山神，也包括其他诸神，所以功德更大。天上飞着鸟，山中有各种动物……它们其实就是诸位神灵的化身或使者。 相似文献

在我们饲料行业，国有企业的状况、国有企业的生存和发展问题，是目前人们关注的一个焦点。因此，“九六话题”开栏第一篇，就来谈谈这件事。春节前，全国饲料工业办公室、中国饲料工业协会召开了“饲料工业国有大中型企业深化改革研讨会”。从这次研讨会上提供的情况看，目前国有饲料企业，在数量上、在固定资产总量上、在总产量、总产值上，仍居于主体地位，发挥着主导作用。但是，近三年来，企业的数量、产量、产值，在全国饲料行业中所占比重逐年下降，而且，效益明显滑坡，面临重重困难。在困境中，国有饲料企业没有坐以待毙，而是在奋… 相似文献

廖建平蜂友是湘永煤矿的退休工人，我大约在10年前认识他，那时，他40多岁，在车站门前义务蜂疗。我刚退休，以蜂会友，便去他那里闲聊。第一次交谈，他有一句话感动了我，他说：“养蜂就要学蜂，一生勤奋，一生奉献。”经过10多年的交往和了解，我认为，他就有点像蜜蜂。 相似文献

人们常说美国是猫狗的天堂，其实，它不仅仅是宠物的天堂，也是一切野生动物的天堂，野生动物与人和睦相处的情景十分感人。８年前，我初入美国的第一个清晨，朦胧中听见叽叽喳喳的麻雀声和呱哇呱哇的乌鸦啼叫，虽然经历了 １０多个小时的长途飞行加上时差正需睡眼，可我睡意全消，跃身下床，“哇！”院子里有好多乌鸦、麻雀和我叫不上名字的小鸟，我已有４０多年没见过这样多的鸟儿了。住地后面依山，前面是片草地，群乌欢鸣，让人振 奋。野兔在草地上蹦蹦跳 跳，松鼠更有意思，沿 树枝窜上跳下，甚 至到院里觅食毫不胆怯。在野外、在公园… 相似文献

一、本地土鸡。这类鸡虽然个体小，生长慢，但其肉味好、市价高，很受城乡消费者的喜爱。据市场调查，近几年，本地土鸡的出售价格一般都是大型肉鸡的两倍。土鸡虽然每只需4个多月才能育成，饲料报酬不及大型肉鸡，但每只土鸡一般都有7至8元的利润。如湖北省大悟县二郎乡一家立体养殖场，1999年养本地土鸡2160元，育成1900只，收入46550元，获利2.6万元。 二、白壳蛋鸡。早在5年前，鸡蛋市场就出现一种新趋势，消费者偏爱白壳蛋，使白壳蛋的价格略高于褐壳蛋，而且白壳蛋鸡的总产量高于褐壳蛋鸡，饲料消耗较少，料蛋比稍低。白壳蛋照蛋也… 相似文献

养殖蜗牛有较好的经济效益，具有资金周转快、用料少、饲养条件低，风险小的优点，根据蜗牛的习性，饲养蜗牛一般有3种方法：（一）露天养殖。农村可利用农田，按照养殖规模确定面积，然后进行翻耕，将土整细，周围植上阔叶树遮阴，四周用网拦住防止蜗牛外逃。城镇可利用平顶房的屋顶，垫上10厘米以上松土，周围种几株葡萄，搭上架遮阳，四周照样用网栏住，此种养殖方式的好处在于，空气新鲜，湿度好，蜗牛生长快，发病少。但要注意3点：（1）天旱时应及时洒水，保持土壤湿润。（2）雨水多时要及时排水。（3）注意天敌与野兽的危害，家中养… 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献

OBJECTIVE: To determine whether serum concentrations of biomarkers of skeletal metabolism can, in conjunction with radiographic evaluation, indicate severity of osteochondrosis in developing horses. ANIMALS: 43 Dutch Warmblood foals with varying severity of osteochondrosis. PROCEDURE: 24 foals were monitored for 5 months and 19 foals were monitored for 11 months. Monthly radiographs of femoropatellar-femorotibial and tibio-tarsal joints were graded for osteochondral abnormalities. Serial blood samples were assayed for 8 cartilage and bone biomarkers. At the end of the monitoring period, foals were examined for macroscopic osteochondrosis lesions. RESULTS: Temporal relationships were evident between certain serum biomarkers and osteochondrosis severity in foals during their first year. Biomarkers of collagen degradation (collagenase-generated neoepitopes of type-II collagen fragments, type-I and -II collagen fragments [COL2-3/4C(short)], and cross-linked telopeptide fragments of type-I collagen) and bone mineralization (osteocalcin) were positive indicators of osteochondrosis severity at 5 months of age. In foals with lesions at 11 months of age, osteochondrosis severity correlated negatively with COL2-3/4C(short) and osteocalcin and positively with C-propeptide of type-II procollagen (CPII), a collagen synthesis marker. Radiographic grading of osteochondrosis lesions significantly correlated with macroscopic osteochondrosis severity score at both ages and was strongest when combined with osteocalcin at 5 months and CPII at 11 months. CONCLUSIONS AND CLINICAL RELEVANCE: The ability of serum biomarkers to indicate osteochondrosis severity appears to depend on stage of disease and is strengthened with radiography. In older foals with more permanent lesions, osteochondrosis severity is significantly related to biomarker concentrations of decreased bone formation and increased cartilage synthesis. 相似文献
