自成立以来，牛肉繁殖工作组（BRTF）一直致力于通过整合研究和推广工作，更有效地将生殖技术的使用转移到该领域，提高美国肉牛群的生产力和盈利能力。一个关键的早期步骤是协调努力，确定有效的肉牛饲养管理协议，并澄清其相关的缩略语。根据同行评审、已发表的研究结果和对从该领域收集的数据的全面审查，制定了肉牛发情和排卵同步化的推荐方案及其首字母缩略词的简短清单。BRTF与兽医和牛AI行业合作制定了推荐方案清单。这些协议及其首字母缩略词在所有主要的AI父系目录中统一呈现，并可在http://www.beefrepro.info上在线获得。每年对方案进行更新，以纳入与肉牛发情周期控制相关的最新研究结果。与爱荷华州牛肉中心合作开发的软件程序“发情同步计划器”现在反映了这些相同的建议。从2002年开始，BRTF在主要的小牛州主办并向1,900多名与会者举办了11个教育讲习班。这些肉牛应用生殖策略研讨会针对牛肉生产商，人工智能行业人员，兽医，相关行业代表和学者。一个国家媒体赞助者在http://www.appliedreprostrategies.com上对最近三次讲习班进行了在线报道。会后评价，开发，以评估从最近的2个研讨会的信息的应用，返回了55%的接触（n = 150）。与会者平均拥有16年（+/- 13.4 SD）的人工智能经验，80%的受访者代表超过100头奶牛。受访者被要求估计人工智能配种小牛的价值相比，自然服务配种小牛，他们的操作在每个动物销售的基础上，17和31%的回答50美元至100美元每只动物和超过100美元每只动物，分别。由于在这些会议上学到的东西，78%的受访者能够更好地解决管理相关问题，60%的受访者对他们一直使用的协议进行了修改，35%的受访者表示他们改变了不同的发情同步协议。
Since its formation, the Beef Reproduction Task Force (BRTF) has worked to enhance productivity and profitability of US beef herds by integrating research and extension efforts with the intent of more effectively transferring the use of reproductive technologies to the field. A key early step was to coordinate efforts in identifying effective breeding management protocols for beef cattle and to clarify their associated acronyms. A short list of recommended protocols and their acronyms for synchronization of estrus and ovulation in beef cattle was developed based on results from peer-reviewed, published research and a comprehensive review of data collected from the field. The list of recommended protocols was developed by the BRTF in cooperation with veterinarians and cattle AI industries. These protocols and their acronyms are presented uniformly in all of the major AI sire directories and are available online at http://www.beefrepro.info. Protocol updates are made annually to incorporate the most recent research findings related to estrous cycle control in beef cattle. The Estrus Synchronization Planner, a software program developed in cooperation with the Iowa Beef Center, now reflects these same recommendations. Beginning in 2002, the BRTF hosted and presented 11 educational workshops to more than 1,900 attendees in key cow-calf states. These Applied Reproductive Strategies in Beef Cattle workshops targeted beef producers, AI industry personnel, veterinarians, allied industry representatives, and academicians. A national media sponsor provided online coverage of the last 3 workshops at http://www.appliedreprostrategies.com. A postmeeting evaluation, developed to assess application of information from 2 recent workshops, was returned by 55% of those contacted (n = 150). Attendees averaged 16 (+/- 13.4 SD) yr of AI experience, and 80% of respondents represented more than 100 cows. Respondents were asked to estimate the value of AI-sired calves compared with natural-service-sired calves to their operation on a per-animal-marketed basis, and 17 and 31% responded $50 to $100 per animal and more than $100 per animal, respectively. As a result of what was learned at these conferences, 78% of respondents were better able to troubleshoot management-related issues, 60% made alterations to a protocol they had been using, and 35% of the respondents indicated they changed to a different estrus synchronization protocol.
