A. Mendoza, Y. Acosta
The effect of supplementation with high-moisture corn grain silage or a commercial concentrate on intake and milk production in dairy cows was evaluated. Forty cows grazing on improved pastures were assigned to five treatments according to a randomized complete block design for 9 weeks: no supplementation, supplementation with 3 or 6 kg (as fed) of high-moisture corn grain silage, supplementation with 3 or 6 kg (as fed) of a commercial concentrate. Although pasture intake decreased with increasing level of supplementation, total nutrient intake was higher. A higher milk, solids yield, and weight gain was observed with increasing level of supplementation. No effect of type of supplement or interaction between these two factors was detected. Supplementation of grazing cows resulted in a better performance, but type of supplement had no relevant effect on the animal´s response.
评价了饲粮中添加高水分玉米青贮或商品精料对奶牛采食量和产奶量的影响。在改良草场放牧的40头奶牛,按照随机完全区组设计,分为5个处理,连续9周:不添加、添加3或6 kg(饲料)高水分玉米青贮、添加3或6 kg(饲料)商品精料。饲粮采食量随饲粮添加水平的增加而降低,但总养分采食量较高。随着添加水平的增加,观察到更高的牛奶,固体产量和体重增加。没有发现补充剂类型的影响或这两个因素之间的相互作用。放牧奶牛的生产性能较好,但添加类型对动物的反应无相关影响。

espanolLa vacunacion es una herramienta ampliamente utilizada en medicina veterinaria para la prevencion de determinadas patologias infecciosas en animales de compania. Debido a la necesidad de unificar conocimientos cientificos y recomendaciones sobre su uso, se elaboro esta guia con pautas basadas en la epidemiologia de las enfermedades en Uruguay y la disponibilidad de vacunas comerciales para su implementacion. Las vacunas de pequenos animales se dividen en esenciales y opcionales. Las esenciales previenen enfermedades de distribucion mundial potencialmente mortales y deben ser administradas a todos los animales, apuntando a lograr una inmunidad poblacional. Las vacunas opcionales deben ser administradas a los animales cuya area geografica, medio ambiente o estilo de vida los exponga a enfermedades especificas. Existen varios factores que pueden interferir con la inmunizacion activa, entre ellos se encuentra los anticuerpos maternales en cachorros, las parasitosis concomitantes, el uso de ciertos farmacos y la senescencia del sistema inmune. Las vacunas son productos biologicos seguros, pero no estan exentos de provocar reacciones adversas en el organismo en situaciones muy particulares, siendo generalmente ademas autolimitantes. En esta guia se proponen diferentes planes de vacunacion para los animales de compania segun su edad, asi como se establecen pautas para la vacunacion en refugios de animales. La misma se realizo considerando las ultimas recomendaciones internacionales, apoyandose en el conocimiento cientifico disponible y la realidad del Uruguay en cuanto a la epidemiologia de las enfermedades.

Due to the need of unifying scientific knowledge and recommendations on its use, this guide was developed with guidelines based on the ep-idemiology of diseases in Uruguay and the availability of com-mercial vaccines for its implementation. Small animal vaccines are divided into core and non-core. The core vaccines prevent from worldwide distributed life-threatening diseases and must be administered to all animals, aiming to achieve herd immuni-ty. Non-core vaccines should be administered to animals whose geographic area, environment or lifestyle, exposes them to spe-cific diseases. There are several factors that could interfere with active immunization, including maternal antibodies in puppies, concomitant parasitosis, the use of certain drugs and senescence of the immune system.

The aim was to compare the performance of the students admitted in 2014, 2015 and 2016 and studied Physiology in the corresponding semester (3rd semester of the Veterinary career). For approving the courses during 2015 the students only required to assist to the practical lectures (1st and 2nd year); in 2016 to go into evaluations (1st year) but only assistance (2nd year); and in 2017 evaluation by tests (1st and 2nd year). The proportion of students who approved the course decreased from 2015 to 2016 (P <0.0001) and increased in 2017 not achieving values form 2016 (P <0.0001). The proportion of students who exonerated was similar in 2015 and 2016, increased in 2017 (2017 vs 2015: P <0.0008 and P <0.0001, 2017 vs 2016: P <0.0001 and P = 0.03 for the proportions of those who assisted and those who approved the course respectively). The proportion of students who approved the exam by December and the qualification obtained was greater in 2017 and 2016 than in 2015 (P <0.0001 for the proportion, P <0.00001 and P = 0.0014 for the qualification). The time required to approve decreased from 2015 to 2016 (P <0.01), being similar in 2017. The exam qualification was greater in 2017 and 2016 than in 2015, without differences between 2017 and 2016. When requirements increased since the students began the first-year courses their performance was better.
目的是比较2014年,2015年和2016年入学的学生在相应学期(兽医职业第三学期)学习生理学的表现。对于2015年的课程审批,学生只需要协助实践讲座(第一年和第二年);2016年进入评估阶段(第一年),但只提供援助(第二年);并于2017年通过测试进行评估(第一年和第二年)。认可该课程的学生比例从2015年到2016年有所下降(P <0.0001), 2017年有所增加,但未达到2016年的水平(P <0.0001)。2015年和2016年被免罪的学生比例相似,2017年有所增加(2017年与2015年:P <0.0008和P <0.0001, 2017年与2016年:P <0.0001和P = 0.03,分别为协助和批准课程的学生比例)。2017年和2016年12月前通过考试并获得资格的学生比例均高于2015年(比例P <0.0001,资格P <0.00001, P = 0.0014)。审批所需时间从2015年到2016年减少(P <0.01),与2017年相似。2017年和2016年的考试资格高于2015年,2017年和2016年没有差异。当学生开始第一年的课程后要求增加时,他们的表现会更好。

espanolEl herpesvirus bovino 4 (BoHV-4) es un gammaherpesvirus dis-tribuido mundialmente. Se ha aislado tanto de animales sanos como enfermos con afecciones respiratorias, vulvovaginitis, mastitis, abortos y endometritis. Realiza infeccion latente en ce-lulas monociticas y del sistema nervioso periferico y/o central. La baja eficiencia reproductiva es un problema identificado en la ganaderia uruguaya. Los agentes virales con impacto repro-ductivo identificados en el pais incluyen el virus de la rinotra-queitis infecciosa bovina (herpesvirus bovino 1, BoHV-1) y el virus de la diarrea viral bovina (BVDV). Teniendo en cuenta que paises de la region han puesto en evidencia la presencia de BoHV-4 y la posible relacion de este virus con problemas reproductivos, el objetivo de este estudio fue explorar la pre-sencia de BoHV-4 en rodeos de bovinos lecheros de Uruguay. Se utilizo ELISA comercial para detectar anticuerpos especifi-cos contra BoHV-1, BoHV-4 y BVDV y PCR para confirmar la presencia de ADN de BoHV-4, realizando posteriormente la secuenciacion genetica. Se utilizaron 597 muestras de sue-ro de vacas Holando de los departamentos de Florida, Duraz-no y Tacuarembo. Del total, 195 (32,7%) tuvieron anticuerpos para BoHV-4, 285 (47,7%) para BoHV-1 y 564 (94,4%) para BVDV. Se detecto el ADN de BoHV-4 en 13/17 muestras. El alineamiento del arbol filogenetico demostro un alto nivel de identidad (97,2%) entre las cepas uruguayas y de otros pai-ses. Esta representa la primera comunicacion de la detecci-on de BoHV-4 en Uruguay. Estudios futuros deben evaluar la diseminacion del virus en la poblacion bovina y su eventual impacto en la salud y produccion ganadera nacional. EnglishBovine herpesvirus type 4 (BoHV-4) is a gammaherpesvirus worldwide distributed. It has been isolated in healthy and un-healthy animals with respiratory infections, vulvovaginitis, mastitis, abortions and endometritis. The persistent infection of BoHV-4 happens in monocytic cells and tissues that are part of peripherical and/or central nervous system. The reduced re-productive efficiency and the low index of procreation are the main problems in the Uruguayan breeding cattle. Reproduc-tive tract infections include two main viruses identified in the country, infectious bovine rhinotracheitis (IBR) virus (bovine herpesvirus type 1, BoHV-1) and bovine viral diarrhea vi-rus (BVDV). In some countries of the region have been evi-denced the presence of BoHV-4 and your possible relationship with reproductive problems. Thus, the main aim of this study is to detect the presence of BoHV-4 in Uruguayan dairy herds. Commercial ELISA were used to detected BoHV-4, BoHV-1 and BVDV antibodies. PCR was used to detect the presence of BoHV-4 DNA and the products were confirmed by Sanger sequencing. Were used 597 samples of Holstein cattle from Florida, Durazno and Tacuarembo provinces. A total of 195 (32.7%) were positive to BoHV-4, 285 (47.7%) to BoHV-1 and 564 (94.4%) to BVDV antibodies. To BoHV-4 DNA,
西班牙牛疱疹病毒4 (BoHV-4)是一种分布在世界各地的γ疱疹病毒。它已从患有呼吸道疾病、外阴阴道炎、乳腺炎、流产和子宫内膜炎的健康和患病动物中分离出来。它在单核细胞细胞和周围和/或中枢神经系统中进行潜伏感染。繁殖效率低是乌拉圭畜牧业的一个问题。在该国发现的具有生殖影响的病毒包括传染性牛鼻干酪病毒(牛疱疹病毒1,BoHV-1)和牛病毒性腹泻病毒(BVDV)。BoHV-4是一种具有传染性的病毒,在乌拉圭的奶牛中很常见,但在其他国家,BoHV-4是一种具有传染性的病毒,在乌拉圭的奶牛中很常见。采用商业ELISA检测BoHV-1、BoHV-4和BVDV特异性抗体,PCR确认BoHV-4 dna的存在,然后进行基因测序。在本研究中,我们使用了来自佛罗里达、杜拉兹-诺和塔夸雷博省的597头牛的血清样本。其中195人(32.7%)有BoHV-4抗体,285人(47.7%)有BoHV-1抗体,564人(94.4%)有BVDV抗体。在13/17份样本中检测到BoHV-4 dna。系统发育树排列显示乌拉圭菌株与其他亲本菌株具有较高的同源性(97.2%)。这是乌拉圭首次检测到BoHV-4。该病毒在牛体内的传播及其对国民健康和牲畜生产的潜在影响应在未来的研究中进行评估。英国牛疱疹病毒4型(BoHV-4)是一种分布在世界各地的γ疱疹病毒。= =地理= =根据美国人口普查,这个县的面积为,其中土地面积为。= = = = BoHV-4 = = = = BoHV-4是BoHV-4的一种变体,BoHV-4是BoHV-4的一种变体,BoHV-4是BoHV-4的一种变体。再生产效率降低和繁殖指数低是乌拉圭牛的主要问题。生殖道感染包括在该国发现的两种主要病毒,传染性牛鼻气管炎(IBR)病毒(牛疱疹病毒1型,BoHV-1)和牛病毒性腹泻病毒(BVDV)。在本区域一些国家,BoHV-4的存在及其可能与生殖问题的关系已得到证实。因此,本研究的主要目的是检测乌拉圭奶牛群中BoHV-4的存在。商用ELISA检测BoHV-4、BoHV-1和BVDV抗体。= =地理= =根据美国人口普查,这个县的面积为。= =地理= =根据美国人口普查局的数据,该县总面积为,其中土地和(1.5%)水。BoHV-4阳性195例(32.7%),BoHV-1阳性285例(47.7%),BVDV阳性564例(94.4%)。To BoHV-4 DNA, 13 samples of 17积极。在乌拉圭和世界范围内,系统发育分析的排列显示出高度的相似性(97.2%)。这是乌拉圭首次诊断BoHV-4的存在。今后的研究必须评估病毒在牛群中的传播及其对健康乳品和全国牛奶生产的可能影响。

Bovine trichomoniasis is a venereal disease caused by Tritrichomonas foetus. It is responsible for economic losses worldwide, causing mainly infertility and abortion in cows and heifers. The diagnosis of this disease is mainly based on microbiological culture and on molecular testing. In Uruguay the parasite has not been reported since 2005. The aim of this study is to report the detection of T. foetus by PCR in preputial smegma from bulls from dairy and beef Uruguayan farms. A total of 310 smegma samples, 121 from dairy-production-bulls and 189 from meat-production-bulls, were sampled. Animals came from 56 farms distributed within 12 different departments of Uruguay. While the PCR analysis of preputial smegma identified 2.25% (7/310) positive for T. foetus, no culture-positive samples were detected. The parasite was detected in 5% (6/121) of the sampled bulls for dairy production, these six animals were from the same dairy farm.  Tritrichomonas foetus was only detected in one out of 189 animals from beef production. This study showed that 3.4% (1/29) and 3.1% (1/32) of beef and dairy farms respectively, were positive for T. foetus infection. PCR is advantageous over culture; therefore, it is an efficient and quick method for the detection of T. foetus in preputial samples. The results of this work suggest that the parasite detection may be underestimated due to the use of only culture-based diagnostics.
牛毛滴虫病是由毛滴虫引起的一种性病。它在世界范围内造成经济损失,主要造成母牛和小母牛不孕和流产。本病的诊断主要依靠微生物培养和分子检测。在乌拉圭,这种寄生虫自2005年以来就没有报道过。本研究的目的是报告用聚合酶链反应(PCR)在乌拉圭奶牛和牛肉农场的公牛包皮包皮中检测到T.胎儿。总共采集了310个包皮垢样本,其中121个来自产奶公牛,189个来自产肉公牛。动物来自分布在乌拉圭12个不同省的56个农场。包皮包皮凝集膜PCR检测发现2.25% (7/310)T.胎儿阳性,未发现培养阳性样本。在奶牛生产公牛中,有5%(6/121)被检出寄生虫,这6头牛来自同一奶牛场。产牛肉的189只动物中,只有1只被检测出有胎毛滴虫。结果表明,牛场和奶牛场分别有3.4%(1/29)和3.1%(1/32)的牛场和奶牛场的T.胎儿感染呈阳性。PCR优于培养;因此,它是一种高效、快速的包皮样品中胎儿弓形虫的检测方法。这项工作的结果表明,由于只使用基于培养的诊断方法,寄生虫检测可能被低估。

Hemangiosarcomas are tumors derived from the vascular endothelium and can occur in any vascularized surface of the organism, although the primary presentation at the mediastinal level is not frequent. We introduce the case of a 7-year-old male crossbreed dog that died suddenly after a single episode of vomiting. At necropsy the animal presented serous-bloody fluid in the abdominal cavity, hepatomegaly and splenomegaly. Disorders in the thoracic cavity included hydropericardium and hydrothorax with serous-bloody appearance. The main macroscopic finding was a mass without anatomical continuity with the heart, rested on the right atrium; and related to the mediastinum immediately cranial to the heart. The histopathological diagnosis was capillary hemangiosarcoma, concluding that the cause of death was due by the cardiovascular disorders that this mass caused by compression of the cardiac basis. Although mediastinal hemangiosarcoma is a rare tumor, it must be included in the differential diagnosis of causes of pleural effusion, pericardial effusion and those disorders associated with cardiac pathologies that cause cardiac tamponade. This is the second case report of a primary mediastinal hemangiosarcoma, and in our knowledge the first directly associated with the sudden death of the patient.
血管肉瘤是源自血管内皮的肿瘤,可发生在机体任何血管化的表面,尽管主要表现在纵隔水平并不常见。我们介绍的情况下,一个7岁的雄性杂交狗,突然死亡后单一发作呕吐。动物尸检显示腹腔浆液血性液体,肝脾肿大。胸腔疾病包括心包积液和胸腔积液,并伴有浆液血性。主要的宏观发现是一个与心脏没有解剖连续性的肿块,位于右心房;并与纵隔相连,直接与心脏相连。组织病理学诊断为毛细血管肉瘤,结论是由于心血管疾病引起的死亡,这种肿块是由心脏基底受压引起的。虽然纵隔血管肉瘤是一种罕见的肿瘤,但在胸膜积液、心包积液以及与心脏病变相关的导致心脏填塞的疾病的病因鉴别诊断中必须包括它。这是第二例原发性纵隔血管肉瘤的病例报告,据我们所知,这是第一例与患者猝死直接相关的病例。

Enzootic bovine leukosis is the main virosis that affects dairy cattle in Uruguay. The subclinical infection causes importants dysfunctions in the immune system impacting directly in the animal health. The aim of this study was to evaluate the immune response of Holstein heifers with positive serology against Leukosis bovine virus (BLV) when they were ordinary immunized against Clostridium perfringens. It was evaluated a seropositive group to BLV animals (n=29) and other seronegative group (n=19) during twelve months. The animals recived three immunizations with a commercial polyvalent vaccine against several Clostridios (days 0, 30, 173). Blood samples were taken in days 0, 30, 60, 90, 180 y 360 post vaccination and then the humoral immune response was analyzed through the use of the ELISA technique to quantify total antibodies against C. perfringens toxins alfa, beta and epsilon. Besides it was in vitro analyzed the amount of neutralizing antibodies against epsilon toxin using the reference technique, seroneutralization. The results demonstrated a low response of neutralizing antibodies to epsilon toxin by SN technique showing no correlation with the results obtained by the commercial ELISA kit. Total antibodies response evaluated using commercial ELISA Kit was variable according to the studied toxoid. No significant differences were found in the immune response against Clostridium perfringens vaccination between BLV seropositive and seronegative animals using the techniques mentioned. The commercial ELISA kit use to analyze the response to vaccination against Clostridiosis, must be discussed and analyzed according to the results of this work.
牛地方性白血病是影响乌拉圭奶牛的主要病毒病。亚临床感染导致免疫系统功能严重失调,直接影响动物健康。本研究旨在评价血清学阳性的荷斯坦小母牛对产气荚膜梭菌普通免疫后对牛白血病病毒(BLV)的免疫反应。对BLV血清阳性组(n=29)和其他血清阴性组(n=19)进行为期12个月的评估。动物接受了针对几种梭状芽孢杆菌的商业多价疫苗的三次免疫(第0、30、173天)。接种后第0、30、60、90、180和360天采血,采用ELISA技术定量测定产气荚膜荚膜原毒素α、β和epsilon的总抗体,分析体液免疫应答。此外,采用参考技术血清中和法,体外分析了epsilon毒素中和抗体的数量。结果表明,SN技术中和抗体对epsilon毒素的反应较低,与商用ELISA试剂盒的结果无相关性。使用商用ELISA试剂盒评估的总抗体反应根据所研究的类毒素而变化。使用上述技术,BLV血清阳性和血清阴性动物对产气荚膜梭菌疫苗的免疫应答无显著差异。用于分析梭菌病疫苗接种反应的商用ELISA试剂盒,必须根据本工作的结果进行讨论和分析。

Respiratory diseases are a major health problem due to the high morbidity and mortality rates, with great economic losses. The aim of this study was to determine the frequency of antibodies against the main viral etiological agents related to bronchopneumonia in cattle (bovine viral diarrhea virus, bovine herpesvirus type-1 and bovine respiratory syncytial virus), searching for associations between these agents and the clinical signs observed. We studied 63 calves from two herds from Sao Paulo, Brazil. After physical examination, the calves were divided into healthy calves and calves with respiratory disease. Serum was obtained for subsequent detection of antibodies by viral neutralization. The association between clinical signs and serological findings was studied. Antibodies against bovine viral diarrhea virus, bovine herpesvirus type-1 and bovine respiratory syncytial virus were detected in 57.10%, 66.70% and 93.70% of the samples. A higher frequency of antibodies against bovine viral diarrhea virus was observed in animals with serous / mucous nasal discharge (P = 0.01). The dehydrated animals (P = 0.008) and those with a rectal temperature above 39.5 oC (P = 0.03) presented a higher frequency of antibodies against the bovine respiratory syncytial virus. The present work presented results superior to those found in studies in farms with extensive system, confirming the importance of management in the transmission of microorganisms.
呼吸系统疾病发病率高、死亡率高,是严重的健康问题,造成巨大的经济损失。本研究的目的是测定与牛支气管肺炎相关的主要病毒病原(牛病毒性腹泻病毒、牛疱疹病毒1型和牛呼吸道合胞病毒)的抗体频率,寻找这些病原体与所观察到的临床症状之间的联系。我们研究了来自巴西圣保罗两个兽群的63头小牛。体检后将犊牛分为健康犊牛和呼吸道疾病犊牛。获得血清,随后用病毒中和法检测抗体。研究了临床症状与血清学结果之间的关系。牛病毒性腹泻病毒抗体阳性率为57.10%,牛1型疱疹病毒抗体阳性率为66.70%,牛呼吸道合胞病毒抗体阳性率为93.70%。牛病毒性腹泻病毒抗体在有浆液/粘液鼻分泌物的动物中出现的频率较高(P = 0.01)。脱水动物(P = 0.008)和直肠温度高于39.5℃的动物(P = 0.03)出现牛呼吸道合胞病毒抗体的频率较高。本研究的结果优于在系统广泛的农场进行的研究,证实了管理在微生物传播中的重要性。
