1 走质量型奶源发展之路的意义，随着世界畜牧业的迅速发展。乳业的发展水平已成为现代农业特别是畜牧业发展水平的重要标志。2000年世界奶业产值占农业总产值的20％。欧美及大洋洲发达国家奶业的发展历史悠久。生产力水平高。奶业产值一般占畜牧业总产值的30％左右。在国民经济中占有重要地位。中国的乳业产值只占农业总产值的3％。远远落后于世界平均水平。 相似文献

三、红豆草 红豆草又称驴食豆、驴喜豆和圣车轴草。原产于欧洲。是豆科红豆属多年生草本植物。在我国的许多地方有引种。栽培效果良好。试验表明。红豆草产量高。适口性好。易于栽培管理。营养物质含量高。是各种家畜喜食的优质牧草。被称为“牧草皇后”。红头草还具有较强的抗旱抗寒能力。一次种植可利用4～6年,且与其它豆科牧草相比。红豆草最大的特点是牲畜食后不得鼓胀病。 相似文献

香精油抗蜂螨作用的研究进展 总被引：2，自引：0，他引：2
香精油及其组分具有显著的抗螨效果。萜类化合物(主要是单萜)是香精油的主要成分。占总量的90％左右。研究者通过筛选试验测定了多种香精油及其一些组分的抗螨能力。大部分表现出良好的抗螨效果。但只有少部分在蜂群试验中表现出强抗螨能力。因此，有必要对此作进一步的研究。以达到最优化目标。同时联合其它防治手段，建立一套全面的害虫防治策略，实现蜂螨的最终控制。 相似文献

牙周病(periodontal disease, PD)是由细菌在牙齿表面聚集形成的牙菌斑和牙结石逐渐侵蚀牙周组织,引发周围组织炎症的一类疾病。根据疾病的发展进程,可分为齿龈炎与牙周炎2个阶段。在小动物临床疾病中牙周病尤为常见,世界范围内约有80%的成年犬患有该病。由于饲主对于犬的口腔保健意识薄弱且该疾病隐秘性较高,患犬就诊时往往已出现牙周支持组织不可逆的损伤,细菌及其毒力因子通过血液循环进入全身从而引发系统性疾病的风险大大提高。但目前犬牙周病的核心致病菌属、菌群失调的原因与发病机制尚不明确。因此,笔者基于高通量测序方法的病原学研究结果,分析与疾病发展相关的微生物群。同时,整合目前世界通用的最新犬牙周病临床诊断分级标准及犬牙周病的中西医防治方案,分析犬牙周病与全身系统性疾病之间的相关性,系统综述犬牙周病在国内外小动物临床领域的研究进展,以期为该类疾病的临床诊疗提供理论参考,推进兽医师在临床实践中更高效地开展该类疾病的诊疗工作,并为犬牙周病相关的临床研究提供思路。 相似文献

Complex interactions between Chlamydia pecorum infection, the immune response and disease exist in the koala. We used quantitative polymerase chain reaction to investigate the relationship between C. pecorum infectious load and ocular and urogenital tract disease. Chlamydia pecorum shedding was generally higher in animals with chronic, active disease than in animals with inactive disease. The absence of ocular disease was generally associated with low levels of shedding, but relatively high levels of shedding in the urogenital tract were detected in some koalas without clinical disease signs. These results suggest a complex disease pathogenesis and clinical course in C. pecorum-infected koalas. 相似文献

2011年秋季,浙江省淳安县的桑园大面积发生一种罕见的桑叶特大病斑病害。病叶呈现菌核病的典型症状:叶面形成灰褐色轮纹水渍状病斑,病斑随着病情发展以同心圆状向外延伸,颜色由里到外逐渐变深;叶背的灰色圆形病斑可见多个同心圆形绒毛状菌丝体和分生孢子。病斑与病斑外的部分组织以及病斑同心圆上的绒毛状组织于光学显微镜下可观察到菌丝体与分生孢子形态,病斑边缘组织块在PDA培养基上分离培养的病原菌都可观察到菌丝体形成的菌核。依据以上症状和病原真菌分离培养的形态特征,初步诊断该病为桑叶菌核病,病原为富克尔核盘菌[Sclerotinia fuckeliana(de Bary)Fuck.]。调查16个样点的480株桑树,株发病率为81.25%,叶发病率为37.63%,发病指数18.5。9～10月份气温24.4～18.7℃,多阴雨天,加之连片桑园通风透光能力较弱且相对湿度较大的环境条件,病原菌繁衍迅速,病害呈流行之势。尚未发现有明显抗性的桑树品种。 相似文献

BACKGROUND: Sinonasal disease is common in cats; chronic inflammatory disease and neoplasia are diagnosed most frequently. Radiographic and computed tomographic (CT) findings in nasal disease have been reported, although involvement of other cranial structures has not been fully described to our knowledge. HYPOTHESIS: We hypothesized that neoplastic or inflammatory obstruction of the auditory tube associated with sinonasal disease could result in CT evidence of effusive bulla disease in affected cats. ANIMALS: 46 cats with sinonasal disease, 18 control cats. METHODS: CT images acquired in cats with (n = 46) and without (n = 18) sinonasal disease were reviewed for evidence of concurrent bulla effusion. CT findings of soft tissue or fluid opacity within the tympanic bulla or thickening of the bone of the bullae were considered evidence of effusive bulla disease. RESULTS: The prevalence of bulla effusion in cats with sinonasal disease was 28% (13/46) and was significantly higher than that observed in cats without sinonasal disease (1/18, P = .043). CT findings that were found in association with effusive bulla disease included imaging features of sinusitis and nasopharyngeal disease. The most common neoplasm associated with bulla effusion was nasopharyngeal lymphoma. Bulla effusion was not observed in any cat with nasal carcinoma. CONCLUSIONS AND CLINICAL IMPORTANCE: Findings of this study suggest that auditory canal dysfunction may play a larger role in feline sinonasal disease than was previously recognized. The implications of these findings for management of cats with chronic inflammatory or neoplastic sinonasal disease require further investigation. 相似文献

It was the intent of this study to define which, if any, radiographic observations corresponded with specific causes of diffuse infiltrative small bowel disease and if radiographic findings could differentiate inflammatory disease from neoplastic disease and either of them from normal. Bowel spasticity, luminal narrowing, and thumbprinting tend to indicate the presence of tumor more often than inflammatory disease. Increased bowel gas in cats and barium adhesion in dogs and cats suggest that a component of enteritis is present. Decreased bowel gas in dogs is more often associated with obstructive disease, but is not helpful in differentiating diffuse inflammatory disease from diffuse neoplastic disease. While several observations that can foster differentiation of neoplastic from inflammatory disease were found, this study also indicated that the UGI lacks a high degree of predictive value other than to indicate the presence of infiltrative small bowel disease. 相似文献

OBJECTIVE: To evaluate the use of systemic disease signs for classifying severity of acute coliform mastitis in dairy cows. DESIGN: Prospective cohort study. ANIMALS: 144 dairy cows. PROCEDURE: Cows were examined at the time of initial identification of disease (time 0) and classified as having mild, moderate, or severe disease on the basis of rectal temperature, hydration status, rumen contraction rate, and attitude. A CBC and serum biochemical analyses were performed, and milk samples were submitted for bacterial culture at time 0 and 48 hours later. RESULTS: 69 cows were classified as having mild disease, 44 as having moderate disease, and 31 as having severe disease. Median WBC and neutrophil counts were significantly lower in cows with moderate or severe disease at time 0 than in cows with mild disease. Band neutrophil count was significantly higher at 48 hours and serum calcium concentration was significantly lower at time 0 and at 48 hours in cows with severe or moderate disease, compared with cows with mild disease. Twenty-eight, 51, and 77% of cows with mild, moderate, and severe disease, respectively, had > 100,000 colony-forming units/ml of milk at time 0. The odds that a cow with severe disease would die or be culled were 3.6 times the odds for a cow with moderate disease and 11.2 times the odds for a cow with mild disease. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that a classification scheme based on readily observable systemic disease signs can be used to classify disease severity in cows with acute coliform mastitis. 相似文献

蓝舌病为OIE规定的需通报疫病，我国将其列为一类动物疫病。该病已经给全球大部分流行地区造成巨大经济损失。我国于1979年首次证明该病存在，且在我国流行初期即造成大量易感动物死亡，给我国畜牧业带来了重大经济损失。但蓝舌病在我国仍属冷门研究方向，我国到底分离鉴定出多少个血清型的蓝舌病病毒，该病在我国的分布范围到底有多广？许多畜牧兽医工作者对这些问题并不是非常清楚。特别是在近年来鲜有蓝舌病引起动物发病死亡报道的前提下，人们对蓝舌病的重视程度进一步降低。本文对蓝舌病在全球的流行概况进行简要阐述，同时，对蓝舌病在我国40年的流行情况进行回顾，希望该病在我国能够得到足够的重视。 相似文献
