奶牛腐蹄病的中西药治疗

正牛腐蹄病是影响养牛场生产的重要疾病之一,在我国各地都表现出较高的发病率。舍饲牛群中发病率高者可达到30%~40%。腐蹄病的发生不仅影响产奶和运动,严重者常导致淘汰。该病主要是因牛栏过度潮湿,蹄部长期被粪尿浸渍角质软化,感染坏死杆菌,促成蹄间腐     

奶牛腐蹄病的防治

奶牛腐蹄病是以蹄部真皮或角质层腐败,蹄间皮肤及深层组织腐败化脓、发出恶臭气味为特征的局部坏死性炎症。在规模养牛场和散养户中均有较高的发病率。腐蹄病不仅影响产奶和运动,严重者可导致淘汰,是阻碍奶牛业发展的重要疾病之一,不可忽视。     

牛羊腐蹄病的防治方法

<正> 牛、羊腐蹄病是以蹄底、蹄叉角质腐烂分解为特征的一种蹄部疾病,它主要是由于厩舍泥泞不洁、长期于低洼沼泽地带放牧,或因蛋白质、维生素饲料不足,致使蹄角质生长发育不良,腐败菌或其它杂菌趁机侵入感染,特别是在蹄部发生外伤时,如不及时处理或处理不当,更易引起本病。牛、羊发生腐蹄病时,蹄角质崩解,趾间皮肤潮红肿胀,知觉过敏,频频举患肢、呈现跛行,严重时,跛行加重,行走困难,不能放牧,导     

浅析牛腐蹄病病因与防治

正牛腐蹄病是一种较为常见的高接触性传染病,为了使牛群饲养人员在牛群饲养的过程中减少牛腐蹄病的发生,保护饲养人员的利益,因此,对牛腐蹄病的病因进行分析,并加以预防是非常有必要的。1牛腐蹄病的症状当牛患有牛腐蹄病后,患病牛会出现食欲减退、体温升高的情况,在针对牛群观察时,会发现患病牛不喜站立,经常出现躺卧的情况。当饲养员使牛站立时,牛会出现患病蹄不愿意着地或出现将患病蹄抬起的行为,在牛行走时出现较为明显的跛行,四蹄受力不均匀,在针对患病牛的病蹄进行检查的过程中,牛的病蹄角质较为完整,对病牛牛蹄叩击或按压时,患病牛经常由于疼痛而挣扎或鸣叫,用刀扩创后,会发现牛蹄蹄底出现小孔或大洞,洞中含有乌黑恶臭的脓水,在病牛牛蹄趾间也可找到溃疡面,病牛创面经常附着有坏死物。出现蹄壳脱落、蹄趾皮肤肿胀溃烂的情况。

An Epidemiological Study of Foot Rot in Pastured Cattle

Using 12 years of data from the common grazing areas at Store Vildmose on the incidence of foot rot in cattle, it was shown that the disease incidence varied significantly between the sections in which the animals were grazing. Differences also existed between breeds in their foot rot incidence. Extraordinarily wet summers were noted to influence foot rot in cattle, and a possible effect of soil pH was also observed.Key words: foot rot, cattle, incidence, epidemiology, breed differences, climatic factors, lameness     

Identification of geographic factors associated with early spread of foot-and-mouth disease

OBJECTIVE: To explore whether early analysis of spatial data may result in identification of variables associated with epidemic spread of foot and mouth disease. SAMPLE POPULATION: 37 farms with infected cattle (ie, case farms) reported within the first 6 days of the 2001 Uruguayan foot-and-mouth disease epidemic. PROCEDURE: A georeferenced database was created and retrospective analysis was performed on case farm location in relation to farm density, cattle density, farm type (ie, beef vs dairy cattle production), road density, case farm distance to the nearest road, farm size, farm ownership, and day of infection. Mean or median results of 1 to 3 day versus 4 to 6 day spatial data were compared. Spatial-temporal associations were investigated by correlation analysis. RESULTS: Comparison of mean or median values between the first 3 days and days 4 to 6 of the epidemic and results of correlation analysis indicated a significant increase in road density, cattle density, and dairy cattle production and a significant decrease in farm size and case farm distance to the nearest road that developed over time. A route that linked most case farms by the shortest possible distance and also considered significantly associated variables was created. It included 86.1% of all case farms reported by 60 days into the epidemic. CONCLUSIONS AND CLINICAL RELEVANCE: Epidemic direction can be assessed on the basis of road density and other spatial variables as early as 6 days into an epidemic. Epidemic control areas may be more effectively identified if local and regional georeferenced data are considered.

Herd and individual animal risks associated with bovine tuberculosis skin test positivity in cattle in herds in south west England

The aim of this study was to investigate the cattle—exposure factors associated with the risk of a bovine animal reacting to a bovine tuberculosis (bTB) skin test at a whole herd test. There were 148 study farms enrolled. These were located in six counties of the south west of England in an area considered endemic for bovine tuberculosis (bTB): 24% were restocked after foot and mouth disease (FMD) in 2001; all farms were located within the Randomised Badger Culling Trial (RBCT) area. Data on cattle on these farms were sourced from the bTB Vetnet database from 1996 to 2004 and from the British Cattle Movement Scheme database. Individual animal records were created that included data on whether or not an animal became a reactor at a full-herd bTB test between 1 June 2001 and 19 August 2004, their prior exposure to cattle with bTB (defined by presence at a bTB test where at least one reactor was detected), whether the animal was homebred, the farm history of bTB and the farm restocking status. Data from 144 farms were used, 4 farms had no data.Cattle were more likely to react to the bTB skin test when they had been present at a previous bTB herd test (or tests) where other cattle had reacted to the skin test. This positively correlated with age and the number of bTB tests an animal had had. Cattle on restocked farms were less likely to react to the skin test compared with cattle on continuously stocked farms. These results highlight the likely importance of exposure to infected cattle at a previous test as a source of infection to cattle that subsequently became reactors and suggest that there was a lower risk of exposure to bTB to cattle in newly formed herds.     

Nonrespiratory diseases of stocker cattle.

Bovine respiratory disease is the most common health issue affecting stocker cattle. There are several nonrespiratory diseases that affect stockers. The more common diseases include rumen tympany, infectious bovine keratoconjunctivitis, coccidiosis, photosensitization, and foot rot. Accurate diagnosis, early treatment, and incorporating appropriate preventive measures can assist cattle production.     

Risk factors for local spread of foot-and-mouth disease, 2010 epidemic in Japan

To provide a basis for effective foot-and-mouth disease (FMD) prevention measures, factors associated with local spread were investigated in this study using data of the 2010 FMD epidemic in Japan. Thirty-eight local clusters within a 500-m radius from source farms were selected. In the clusters with pig source farms, more neighboring farms were infected in a short time compared with the clusters with cattle source farms. The influence of distance and wind upon local spread did not show a significant difference between infected and noninfected neighboring farms. Large-size pig farms posed a greater risk of inducing local spread; the odds ratio with reference to small-size cattle farms was 16.73. Middle-size and large-size cattle farms had a greater risk of infection; odds ratios with reference to small-size cattle farms were 15.65 and 25.52, respectively. The present results are useful for understanding features of local spread and prioritizing farms for control measures.     

坏死杆菌白细胞毒素作为腐蹄病亚单位疫苗候选抗原的研究前景

腐蹄病（foot rot）是侵害反刍动物趾间皮肤及深层软组织为主的,严重影响奶牛生产性能和产奶质量的一种常见疾病。由于传统的灭活菌苗具有免疫效果差、副反应严重及大量生产困难等缺点,使腐蹄病基因工程疫苗的研究成为热点。笔者对坏死杆菌白细胞毒素作为腐蹄病亚单位疫苗候选抗原研究的最新进展进行综述,希望为腐蹄病亚单位疫苗的研究提供参考。
