牛消化系统疾病的病因与治疗

消化系统疾病属于牛只饲养过程中多发疾病类型,发病情况错综复杂,不同的病情有不同的治疗方式,治疗不当容易耽误疾病治疗,甚至导致牛只死亡。本文分析了牛食道梗塞、牛前胃迟缓和牛急性胃扩张等消化系统疾病的发病原因,并针对性提出了治疗措施,提升疾病治疗效率,降低牛只饲养风险,切实保障牧民利益。     

牛消化系统疾病发病原因及治疗

近年来,我国肉牛养殖数量不断增加,养殖规模不断扩大。消化系统疾病是养牛过程中极易发生的一类疾病,如果预防不当、治疗不及时极容易造成养殖户巨大的经济损失。1牛急性胃扩张1.1发病原因牛急性胃扩张是养牛过程中较为常见的一种消化系统疾病,该病的发生主要是由于牛只在饮食过程中,养殖人员没有严格控制其食量,导致其过度饮食,与此同时牛只进食速度过快,导致其胃部急性扩张。从机理方面来看,该病主要是由于牛只所食入过量的饲料无法在短时间内充分消化,导致其在胃中聚集,从而引发牛只胃壁扩张。牛急性胃扩张的发生会导致牛只神经功能紊乱,进而影响牛只正常的消化功能。     

牛胃肠炎病的诊治和预防

<正>牛胃肠炎病是牛饲养过程中发病率较高的一种疾病,炎症集中于牛胃肠黏膜、胃部和胃肠深层组织等,患病后如果病牛得不到及时、有效的治疗,不仅会对牛只正常生长和发育造成不良影响,降低牛只生产性能,甚至会直接导致牛只死亡,严重影响牛场的养殖效益。因此,在牛养殖过程中需要详细了解牛胃肠病的发病隐患、诊治方法和预防措施等,尽可能地降低疾病影响,保证养殖效益。     

牛副流行性感冒的防控措施

牛副流行性感冒疾病是牛养殖过程中一种常见的呼吸道传染性疾病,主要会导致牛只出现呼吸道感染、体温升高、咳嗽以及肺炎等症状,严重降低了牛只的生产性能和健康状况,阻碍了牛只养殖产业的科学发展。牛副流行性感冒主要由3型牛副流感病毒(BPIV3)所导致,在牛只的发病初期合理使用抗生素可以获得良好的治疗效果。本文将对牛养殖过程中牛副流行性感冒疾病出现的诊断措施以及相关的防治措施进行介绍,旨在为牛只的健康养殖带来帮助。     

牛消化系统疾病的诊断及治疗

我国的牛养殖业开始向着集约化和规模化的发展,但只关注牛群的数量和产量,忽视了对疫病的防控和治疗工作,加之受到寄生虫、饲养管理和人为等因素的影响,导致牛患病的概率增加,尤其是有消化系统方面的疾病越来越多,病情复杂,导致牛只死亡。为此,应该分析有消化系统方面疾病发生的原因,结合不同的消化系统疾病采取不同的治疗方式。本文主要阐述了牛消化系统疾病的病因,具体论述了治疗该疾病的措施。     

牛消化系统疾病的治疗措施

随着养殖规模的不断扩大,养牛过程中疾病的发病率也在不断上升,尤其是牛消化系统疾病,发病率可达60%。如果处理不及时,其死亡率也很高,给养殖户造成巨大的经济损失。牛消化系统疾病的临床症状各不相同。正确认识牛的疾病,及时采取预防措施尤为重要。     

牛病毒性腹泻的准确诊断及预防

牛病毒性腹泻/黏膜病是由牛病毒性腹泻病毒引起的一类重要的传染性疾病,给养牛业造成了严重的经济损失。其不仅可以产生多种临床症状,并且能降低感染牛只的免疫力,从而继发感染其它病原,大大增加了牛只的发病率及死亡率,持续性感染牛只可能并不表现明显的临床症状,但却是重要的病毒传播源,为疫病防控带来很大困难。针对以上问题,就牛病毒性腹泻病毒的流行、感染后所表现的临床类型、处理方法及防控要点进行综述,希望能为该病的防控提供科学的技术支持。     

牛消化系统疾病的病因分析与治疗措施

牛消化系统疾病是一种高发的内科疾病,对牛的正常生长会产生非常重要的负面影响,虽然消化系统疾病不会传染其它健康牛类,但是在牛患病后会影响牛正常的生长发育,甚至会使牛的繁殖能力受到影响,牛消化系统疾病也会导致牛体重减少.因此为减少对养殖户的经济损失,本文对牛消化系统的常见疾病进行分析,并总结治疗方式,帮助养殖户能够及时的预...     

牛瘤胃酸中毒的综合防治

牛瘤胃酸中毒是当前养牛过程中非常常见的一种胃部疾病。如果在日常的饲养过程中,牛只在极短的时间内食入了过多容易被发酵的碳水化合物类饲料,这些饲料会导致大量的乳酸在牛瘤胃内生成,进而导致牛的乳酸中毒。该病通常发病较急,会在极短的时间内导致牛只出现严重的全身症状,是一种死亡率较高的疾病。     

牛消化系统疾病的病因与治疗方法

牛常见消化系统疾病有牛瘤胃臌气、瘤胃积食、前胃弛缓、胃肠炎,对牛的生长健康有非常严重的影响的主要症状和病因养殖人员应加强对牛常见消化系统疾病的了解,平时注意疾病的预防和治疗,尽量降低牛消化系统疾病造成的经济损失。     

牛口蹄疫病防治

牛口蹄疫是国家一类重特大传染性疾病,会严重威胁地区牛养殖产业的安全,给养殖户带来巨大经济损失,降低牛养殖产业的生产效益。再加上牛口蹄疫是一种人畜共患病,疾病传播流行中,如果没有做好个体防护很易造成病毒,向人扩散蔓延,威胁周边居民的生命财产安全。在充分掌握牛口蹄疫病发生现状的基础上,需要进行认真细致的分析,构建针对性的防控措施,降低疾病发生流行造成的危害。在充分掌握新宾县牛口蹄疫发生现状的基础上,对牛口蹄疫疾病的诊断和提出防治措施。     

牛传染性鼻气管炎防治措施

牛传染性鼻气管炎是由疱疹病毒感染引发的一种急性传染性疾病,临床上以呼吸道黏膜出现严重水肿、充血、坏死、形成浅表性溃疡病灶为主要特征。根据发病部位的不同,主要表现为阴道炎、结膜炎、脑膜炎、流产等其他病症,因此该类疾病属于一病因引发的多病症的传染性疾病。临床上牛传染性鼻气管炎只发生于牛,不会发生于其他动物,病毒的传播流行具有专一性。近年,随牛养殖业的不断向前发展,传染性鼻气管炎的发生率呈现逐渐升高趋势,虽然造成的死亡率较低,但是会严重影响牛群正常生长发育,甚至会造成繁殖母牛严重流产,使繁殖母牛的利用年限极大缩短,引发严重的繁殖障碍。该文主要论述牛传染性鼻气管炎的诊断和防治措施。     

Osteochondrosis in cattle.

Osteochondrosis is a poorly understood condition that affects many species, including cattle. Its incidence is not fully appreciated in the cattle industry for many reasons. Most of the reports show a male, purebred predilection, but this may simply be a result of the typical population for which medical attention is sought. With the increasing value of female breeding stock, a less skewed distribution of the disease will most likely result. Distribution of lesions is similar to that in the horse, with the stifle and tarsus most commonly affected. Treatment is divided into medical and surgical options, but neither seem to be strikingly effective as of yet. Surgical techniques include arthroscopy and arthrotomy, and both have their complicating factors. How osteochondrosis as a disease will affect the cattle industry is still to be decided. If the incidence rate does increase with more animals being valued for their economic potential, then treatment options will surely be reevaluated and refined.

Bovine respiratory disease in feedlot cattle: phenotypic, environmental, and genetic correlations with growth, carcass, and longissimus muscle palatability traits

Bovine respiratory disease (BRD) is the most costly feedlot disease in the United States. Selection for disease resistance is one of several possible interventions to prevent or reduce the economic loss associated with animal disease and to improve animal welfare. Undesirable genetic relationships, however, may exist between production and disease resistance traits. The objectives of this study were to estimate the phenotypic, environmental, and genetic correlations of BRD with growth, carcass, and LM palatability traits. Health records on 18,112 feedlot cattle over a 15-yr period and slaughter data on 1,627 steers over a 4-yr period were analyzed with bivariate animal models. Traits included ADG, adjusted carcass fat thickness at the 12th rib, marbling score, LM area, weight of retail cuts, weight of fat trim, bone weight, Warner-Bratzler shear force, tenderness score, and juiciness score. The estimated heritability of BRD incidence was 0.08 +/- 0.01. Phenotypic, environmental, and genetic correlations of the observed traits with BRD ranged from -0.35 to 0.40, -0.36 to 0.55, and -0.42 to 0.20, respectively. Most correlations were low or negligible. The percentage of carcass bone had moderate genetic, phenotypic, and environmental correlations with BRD (-0.42, -0.35, and -0.36, respectively). Hot carcass weight and weight of retail cuts had moderate, undesirable phenotypic correlations with BRD (0.37 and 0.40, respectively). Correlations of BRD with LM palatability and ADG were not detected. Low or near zero estimates of genetic correlations infer that selection to reduce BRD in feedlot cattle would have negligible correlated responses on growth, carcass, and meat palatability traits or that selection for those traits will have little effect on BRD susceptibility or resistance.     

Risk factors for lower respiratory tract disease in a cohort of feedlot cattle

Using data collected from company lot records, potential risk factors related to feedlot management, the cattle, and climate were determined. The risk factors were analyzed by use of weighted multiple regression techniques to determine their effects on the incidence of lower respiratory tract disease in a cohort of 95 lots containing 17,696 cattle. The gender of the cattle, the number of days that groups of cattle filled a lot, pregnancy checking of heifers, and the average temperature change in the first 14 days in which the cattle were on feed significantly influenced the incidence of lower respiratory disease. The incidence of lower respiratory tract disease was most influenced by risk factors in the first 30 days on feed.     

Effect of mass medication with antibiotics at feedlot entry on the health and growth rate of cattle destined for the Australian domestic market

OBJECTIVE: To examine the effectiveness of mass medication with long acting antibiotics at feedlot entry on lot-fed Australian domestic cattle during a period of high risk for bovine respiratory disease (BRD). DESIGN: Systematic allocation at feedlot entry of tilmicosin, long acting oxytetracycline or no antibiotic treatment, to cattle lot fed for the Australian domestic market. Comparisons of growth rate, disease occurrence and mortality were made between the groups at the conclusion of the feeding period. RESULTS: Cattle medicated with tilmicosin at 10 mg/kg body weight on entry to the feedlot grew 0.08 kg/d faster than cattle medicated with oxytetracycline at 20 mg/kg body weight and non-medicated cattle. There was no significant difference in growth rate between oxytetracycline medicated cattle and cattle not medicated with antibiotic at feedlot entry. Cattle medicated with tilmicosin at feedlot entry had 8 fewer cases of disease per 100 animals compared with cattle not medicated with antibiotic at feedlot entry. There was no significant difference in disease occurrence between oxytetracycline medicated cattle and those not medicated with antibiotic at feedlot entry. CONCLUSION: Mass medication with tilmicosin at feedlot entry of cattle destined for the Australian domestic market may be used to reduce disease occurrence and increase growth rate during periods of high risk for BRD.

牛传染性鼻气管炎诊断和防治

牛传染性鼻气管炎又被称为坏死性皮鼻炎,是由牛传染性鼻气管炎病毒感染引发的一种急性呼吸道疾病。不同年龄的牛感染传染性鼻气管炎病毒后表现的临床症状存在一定差异,年龄较小的牛会表现为明显的临床症状,年龄较大的牛呈现隐性感染或持续性感染,患病牛长时间或终生携带病毒,污染周围环境后造成病情反复流行,病情难以控制、难以消灭。牛传染性鼻气管炎造成的死亡率相对较低,但是会严重影响牛群正常生长与采食,需要掌握该类传染性疾病的流行特点,并进行严格诊断,然后构建有效的防控措施,降低发病率。该文分析牛传染性鼻气管炎的流行病学、临床症状、病理变化、诊断方法和防治措施。
