DairyBeef: maximizing quality and profits--a consistent food safety message.

To respond to meat safety and quality issues in dairy market cattle, a collaborative project team for 7 western states was established to develop educational resources providing a consistent meat safety and quality message to dairy producers, farm advisors, and veterinarians. The team produced an educational website and CD-ROM course that included videos, narrated slide sets, and on-farm tools. The objectives of this course were: 1) to help producers and their advisors understand market cattle food safety and quality issues, 2) help maintain markets for these cows, and 3) help producers identify ways to improve the quality of dairy cattle going to slaughter. DairyBeef. Maximizing Quality & Profits consists of 6 sections, including 4 core segments. Successful completion of quizzes following each core segment is required for participants to receive a certificate of completion. A formative evaluation of the program revealed the necessity for minor content and technological changes with the web-based course. All evaluators considered the materials relevant to dairy producers. After editing, course availability was enabled in February, 2003. Between February and May, 2003, 21 individuals received certificates of completion.

Development and evaluation of a leadership program for veterinary students.

Leadership skills are important for many facets of professional life, but no known leadership training programs exist in North American veterinary schools. It was the purpose of this project to develop, deliver, and evaluate a leadership program for first-year veterinary students. Leadership attributes emphasized in the course included effective communication, openness to learning from others, self-awareness, commitment beyond self-interest, motivation, decision making, understanding issue complexity, and team building. The five-day course was delivered to 21 new veterinary students randomly selected just prior to their first-year orientation in the fall of 2000. Participants ranked themselves higher than non-participants in a post-course evaluation on their ability to be effective leaders. Participants reported an increase in self-confidence and a clearer understanding of their leadership roles. Participants also noted new support systems among co-participants and expressed a new ability to consider complex issues more broadly. Most reported that they frequently used enhanced skills in giving and receiving feedback and team building. Other leadership tools identified as valuable included negotiation, group dynamics, a structured approach to problem solving, time management, and an awareness of personal learning style preferences as a means to improve communication.

Motivations for and barriers to engaging in continuing veterinary medical education.

OBJECTIVE: To identify reasons for engagement in continuing veterinary medical education (CVME) activities, obstacles to participation, ways to provide more effective programs, and ideas to improve participation in CVME. DESIGN: Focus group interviews. SAMPLE POPULATION: Selected practicing veterinarians from a state that did mandate continuing education for relicensure. PROCEDURE: 12 focus group interviews were held throughout the state of California between May and September 1998. Practitioners were asked to respond to questions about where they obtain information to improve their practice, what value they see in CVME, what motivates them to participate, what obstacles to CVME participation exist, and ways CVME providers and practitioners could overcome those obstacles. RESULTS: 84 practitioners participated in the focus group interviews. In addition to the educational value of CVME, participation was used to rejuvenate practice life and prevent feelings of isolation. Continuing education activities ranged from problem-oriented chats with colleagues to formal educational programs. Timing of events, distance, money, solo practice, stage of career, and family demands were identified as barriers to participation. Designing and marketing CVME with specific learning objectives and for specific career stages and using new educational delivery technologies were suggested to overcome some of these barriers. CONCLUSIONS AND CLINICAL RELEVANCE: If CVME is to improve practice and patient care, it should be integrated into a practice's strategic planning and considered a legitimate business expense. Decisions about CVME participation are made easier if program objectives are clearly outlined.

Age, geographic, and temporal distribution of fecal shedding of Cryptosporidium parvum oocysts in cow-calf herds.

OBJECTIVE: To evaluate fecal shedding of Cryptosporidium parvum from California cow-calf herds with respect to age, geographic region, temporal effects, and association with watery feces. ANIMALS: Cows and calves from 38 beef cow-calf operations. PROCEDURE: Fecal specimens were collected and examined for C parvum oocysts, using immunofluorescent microscopy. Associations between age, geographic region, month of collection, watery feces, and likelihood of shedding C parvum were evaluated. RESULTS: 3.9% of cattle were shedding C parvum oocysts. Prevalence of shedding among calves ranged from 0 to 13%, and was 0.6% among cattle > or = 12 months old. The odds of shedding C parvum among 2-month-old calves were 41 times greater than among cattle > 4 months old. The odds of shedding C parvum among cattle tested in May were 8.7 times greater than among cattle tested during June, July, or August. The odds of infected individuals having watery feces were 3 to 4 times greater than for noninfected individuals, but the etiologic fraction was only 8 to 9%. CONCLUSIONS AND CLINICAL RELEVANCE: Substantial fecal shedding of C parvum by cow-calf herds was limited to calves 1 to 4 months old, with low prevalence detected in older animals. Risk of contamination of watersheds with C parvum was limited to those periods when young calves were in the herd. Although the odds of having watery feces were greater for animals infected with C parvum than for noninfected animals, the low etiologic fraction suggests that most calves with watery feces were not infected with C parvum.

The use of computers in dairy practice.

Computers are used by dairy practitioners in two broad categories: one is to help evaluate clients' herd performance; the other is to help the veterinarian manage his own practice. Both aspects are discussed in this article.

Normal reproductive parameters in large "California-style" dairies.

Reproductive parameters are important in evaluating modern dairy management performance. Successful dairying results from constant attention to daily events, requiring more sensitive and immediate measurements of performance. Definitions of formulas, numerators, denominators, and population included or excluded are essential for proper interpretation and comparison of results. Veterinarians understanding these statistics and indexes, and using stratification of data to investigate production losses, will serve their clients well. My advice is to approach a herd with a perceived reproductive problem by evaluating these parameters; they are the means of determining if a problem exists and, if so, where it is. Find out how the various parameters are calculated so your interpretation will be correct. Herds with average days in milk of less than 165, culling rates below 25 per cent, and a milking rate of 85 per cent or more do not have long-term reproductive problems. If management techniques fail to achieve these levels, first look at those areas involving people. Conception rates measure all the components that, when multiplied, equal fertility: insemination technique, semen quality, heat detection accuracy, and the cow factors involved. Poor conception rates require investigation into these areas individually. Heat detection intensity leading to prolonged days in milk at first service is another common finding. Comparison of inseminators and sires may identify a problem area. Cow factors require more intense investigation to determine their cause. Use the information outlined in the periparturient period to assist you. In most cases, a combination of failures in many of the independent factors creates the problems in reproduction that we encounter. A large data base including all the information discussed and additional information is necessary to define, correct, and monitor reproductive management performance. Since performance ultimately is determined by the quality of the labor force, ongoing monitoring for accountability and education is necessary for success.
