In order to improve the beef performance of Yanbian Yellow Cattle, the blood of beef breed Limousin was introduced.Crossbreeding, reciprocal breeding and stabilized crossing methods were used.And large-scale parallel crossbred had come into being.The results showed that the crossbred had steady genetic performance.It was stronger, burlier and its body was longer than Yanbian Yellow Cattle.The crossbred looked better.The growth performance of the crossbred was significantly higher than Yanbian Yellow Cattle.The slaughter performance, feeding efficiency and beef performance were improved.According to statistics, there are 98800 crossbred cattle with 1/4Limousin blood ,in which the number of the breeding cows is up to 39520.The crossbreeding reach over four generations and the crossbred has the characteristics of beef cattle.

为了确保规模化养殖场肉牛养殖与牛肉来源安全,建立从肉牛生产环节到餐桌的全过程安全控制体系,特引进HACCP(危害分析及关键控制点)体系的管理程序.根据肉牛生产过程的工艺流程图,制定饲养过程危害分析表,进行危害分析,列出肉牛生产过程中的危害因素和可能出现的所有潜在的危害因子,设置七个关键控制点(ccp)和关键点限值(CL),并对CCP实施过程进行监控和制定纠偏措施.结果表明,在规模化肉牛养殖场实施了
本实验以玉米秸秆为主要研究对象,通过纤维素降解菌的富集培养、分离提纯及玉米秸秆的降解率和CMC酶活性测定方法,对采自新疆的26个土样在25℃±1进行富集培养30d,初步得到能以秸秆为唯一碳源生长的34株霉菌,并对其进行分离提纯,得到14株霉菌,接着通过CMC酶活实验选出酶活最强的四株霉菌(M3＞M42＞M6＞M21),并对其作出形态学初步鉴定.结果为:M6和M42属于青霉属,M3和M21属于曲霉属
总结归纳来自同一肥育牛场,并在同一肉牛屠宰厂屠宰的肉牛2000余头,分析影响肉牛屠宰效益的因素.资料显示影响肉牛屠宰加工效益的第一因素是牛肉大理石花纹丰富程度;肉牛自身条件(性别、年龄、背部脂肪厚度和颜色、肥育时间、体重等)是影响屠宰加工效益的第二因素;屠宰环境条件也影响肉牛屠宰加工效益.
目的：本试验旨在研究日粮精粗比对6月龄荷斯坦公牛网胃和瓣胃器官发育及组织形态的影响.：方法：选择9头健康的荷斯坦奶公牛,随机分为3个处理组,日粮精粗比分别为6∶4(处理Ⅰ组)、5∶5(处理Ⅱ组)和4∶6(处理Ⅲ组),试验3个月后,采用组织学技术研究3个处理组试验牛网胃和瓣胃官发育及组织形态的变化.结果：试验结果表明:(1)各试验组网胃和瓣胃的黏膜结构均比较完整;(2)网胃和瓣胃的鲜重及鲜重/体重随
畜产品生产企业建立质量追溯系统已经提上日程,牛肉作为价值较高的肉食品,近年来消费量不断增加,其安全可追溯性的也越来越受到重视.本文对国内近年来牛肉质量追溯系统项目案例进行了总结,对技术特点进行了详细分析,并从信息化、自动化、政府及消费者四个方面对我国牛肉质量追溯系统应用的影响进行了分析, 牛肉企业业务模式，产业结构，管理水平不同，使追溯系统的复杂程度也不相同，企业应依据自身管理特点和信息化基础，从
目的：适应中国牛肉外贸和出口需要,并为国内牛肉安全消费提供保障.方法：利用Visual Basic6.0面向对象编程技术和SQL Server 2000大型关系数据库技术,采用耳标与分割肉号码及对应的EAN/UCC条码技术等动物标识方法,构建牛肉安全生产加工全过程质量跟踪与追溯系统,系统包括信息查询、信息采集、系统设置、帮助和退出等5个主要功能模块.结果：研发了一套适合中国牛肉安全生产的质量跟踪与
目的：为了让消费者购买牛肉后可以追溯到牛肉生产的全过程,实现牛肉可追溯系统的智能、快捷、实用的目标,方法：本研究引入"RFID+条码"技术,对肉牛及生产的牛肉进行标识,跟踪牛肉全过程.并设计开发了网络化牛肉可追溯系统,系统采用JSP设计面向对象的动态网页,采用My SQL设计数据库,运用B/S(浏览器/服务器)体系结构,结果与结论：将管理系统放在互联网上,实现了牛肉可追溯系统的网络化管理,使牛肉可
