固原市设施养殖肉牛应激反应原因调查     

于利子 《中国牛业科学》2014,(5):68-71

规模化设施养殖是肉牛生产的发展趋势,由于温棚设计建造不合理、牛群不断扩大、生活规律和环境变化等,导致肉牛生理活动改变,从而使肉牛处于适应新环境条件下的被动状态,应激反应也就随之增多,如何减轻应激反应已成为肉牛设施养殖过程中的关键。从源头上探讨设施养殖肉牛应激反应的发生原因,对防控应激反应,提高肉牛设施养殖健康水平有重要意义。  相似文献

姜德科  昝林森  杜书增 《中国牛业科学》2014,40(6):47-54

为了克服肉牛品种选育和饲养管理中存在操作不规范、数据记录不全、数据保存不完整等问题,提高肉牛养殖场信息化管理水平,提高企业的经济效益.本文根据肉牛饲养和牛场管理的需要,以Visual Studi0 2008为系统开发平台,利用VB.NET面向对象编程语言和SQL Server 2005大型关系数据库及Crystal Reports（水晶报表）技术进行系统开发.构建了基于VB.NET和SQL Server的肉牛场信息管理系统,系统包括文件、牛群管理、生产管理、育种管理、库存管理、人事管理、统计分析、系统维护和帮助九个主要功能模块.该系统实现了肉牛生产的系统化和牛场管理的信息化,促进肉牛品种选育的进程,降低企业的管理成本,有效地提高了肉牛养殖的效率.  相似文献   

华亭县肉牛养殖业发展现状及对策建议     

杨永栋  罗干  岳东旭 《中国牛业科学》2014,(3):86-88

华亭县自古以来就是黄牛的主产区之一,又是秦川牛、早胜牛的边缘产区,养牛已成了当地农户发展致富的主导产业。本文在调查研究的基础上,对华亭县肉牛养殖业发展中存在的问题进行了综合分析,基础母牛保护力度不大、资金短缺、技术匮乏、基础设施落后,产业加工链短是制约华亭县肉牛养殖业发展壮大的主要瓶颈,针对以上问题,提出了一些可行的对策建议,以促进该县进一步加快肉牛改良、扩繁和规模化发展,降低养殖户养殖成本,提高经济效益。  相似文献   

黑龙江省某镇肉牛布鲁氏菌感染情况调查     

汪淼  王靖飞  张俊峰  孙刚 《中国动物检疫》2014,31(11):48-50

为了解黑龙江省B镇肉牛的布鲁氏菌病流行现状,从而评估该病在当地牛群中的流行状况及人感染布鲁氏菌的风险,本研究以估计个体及群流行率为目的,按照预期流行率0.5%,可接受误差0.3%,置信水平95%对B镇531个肉牛养殖场户养殖的3535头肉牛进行随机抽样,获得血清样本1334份,用虎红平板凝集试验和试管凝集试验两种方法检测均为阳性的牛即为布病患病牛,同时对养殖户就养殖模式、动物来源、更新方式、既往病史、养殖规模等方面进行问卷调查。血清检测结果显示,虎红平板凝集5份阳性,阳性率为0.37%,对5份阳性血清进行试管凝集试验复检,布鲁氏菌抗体全部为阴性。同时回收问卷531份,有效问卷389份,合格率73.3%。根据本次检测结果,B镇肉牛布病个体流行率接近于零,牛群中没有发现利于布鲁氏菌感染的风险因素。  相似文献

Prevalence and Characteristics of Salmonella in the Beef Chain in the Republic of Ireland     

B. K. Khen  O. A. Lynch  J. Carroll  D. A. McDowell  G. Duffy 《Zoonoses and public health》2014,61(8):534-536

The study investigated the prevalence, concentration and characteristics of Salmonella spp. in the Irish beef chain. A total of 900 samples including bovine hides, carcasses and ground beef were examined for the pathogen over a 2‐year study (July 2007–June 2009). Salmonella prevalence was low in all sample types; bovine hide (0.75%, 3 of 400); carcasses (0.25%, 1 of 400); and ground beef (3%, 3 of 100). All positive samples contained the pathogen in low concentrations (<10 CFU per cm² or per g). Serovars recovered were S. Dublin from hide and carcasses and S. Braenderup in ground beef. All isolates were susceptible to 13 anti‐microbials. The study highlights that Salmonella can be found at low levels at all stages of beef chain production, processing and retail and that there is a need for multiple hurdle interventions and practices along the beef chain, which will reduce consumer exposure to this pathogen.  相似文献

康瑞娟  张小栓  傅泽田  穆维松 《农业工程学报》2010,26(1):227-231

为提高肉牛养殖信息采集与传输的自动化程度准确性,该文提出了基于个人数字助理（PDA）和有限状态机 （FSM）的肉牛养殖可追溯信息采集与传输方法。利用PDA采集肉牛的日常养殖信息;在信息传到PC的过程中,通过利用有限状态机原理,以事件驱动的方式实现了PDA与PC之间的串口信息传输。重点研究了串口传输过程中有限状态机的建模,该方法改变了肉牛养殖信息传统、人工的采集与传输的方式,实现了养殖场信息的快速、准确的采集与传输。  相似文献   

Effect of Different Crossbred Combinations on Fatting Performance in Beef Cattle

This study was aimed to determine the effects of different crossbred combinations on fatting performance in beef cattle. Using single factor randomized block design, 30 bulls (health, similar weight and age) were chosen, Simmental cattle×Kerqin beef cattle (group A), Charolais cattle×Kerqin crossbred beef cattle (group B) and Kerqin beef cattle (group C) were divided into three groups with 10 bulls per group. After 95 d, the body weight, slaughter performance, meat quality and the economic benefits of fattening were measured. The results showed that there were no significant influence on dry matter intake among trials (P>0.05). The F/G, ethanolic extract (EE) of muscle in crossbred groups (groups A and B) were significant lower than group C (P<0.05). The weight of carcass, weight of meat, rate of carcass, and the weight of shank, plate, chine and rump in crossbred groups were significant higher than group C (P<0.05). There were no significant difference in content of amino acids among groups (P>0.05),and it had difference in the content of palmitoleic acid (PAA),stearic acid(SA) and linoleic acid (LA). In this trial, it had better fattening performance and the economic benefits in crossbred cattle groups than Kerqin beef group cattle, but the ethanolic extract and unsaturated fatty acids of muscle in Kerqin beef cattle were higher than the crossbred groups, and it had better fattening performance by crossbred.  相似文献
