Accomplishments

Frequencies of DNA polymorphisms differ among Angus, Brangus, and Brahman cattle. Heterozygous genotypes appear advantageous in Bos indicus-influenced composites. <br /> <br /> DNA polymorphisms in genes of the GH axis or its transcriptional regulators appear to predict growth and or reproductive traits in Brangus bulls and heifers (CAUTION: original studies used single locus associations). <br /> <br /> SNP discovery efforts in candidate genes (fine mapping) are very productive. dbSNP limited. <br /> <br /> Identification of haplotype blocks and tag SNP appears to be a much more effective strategy within a pathway/candidate gene approach to MAS. <br /> <br /> Desert adaptation is measurable. Question is whether it is an effect of genetics and (or) environment (i.e., management, learned behavior, etc&)?<br /> <br /> Developed and released to the beef industry a new methodology for calculating stayability EPDs that utilizes early-life indicators to improve the accuracy of those EPD. Traditional stayability EPD represent the probability that an animals daughters will remain in the productive herd until 6 years of age. Given this definition sires are at least 8 years old before their daughters ever have an observation for stayability. Using a new methodology we incorporate information on stayability from earlier ages in a females productive life.<br /> <br /> Developed methods for inferring sires genotypes when DNA from the sires is not available. It will help to carry out Quantitative Trait Loci mapping in range populations. Also arrived to the conclusion that DNA paternity programs can be economically efficient.

Accomplishments

Accomplishments: <br /> <br /> 1. Research efforts at Texas A&M have established a unique resource of Bos indicus-Bos taurus cattle to identify genomic influences on cattle health and beef cow productivity and includes genomic information, pedigrees, and detailed production phenotypes on approximately 450 breeding age females. This project complements efforts of other locations in this and other multistate projects and international efforts, and provides data that are desired by the U.S. beef cattle industry. <br /> <br /> 2. The first feed intake test at the new CSU Feed Intake Unit was completed in February 2010. The first test included approximately 85 Hereford and Angus bulls and heifers, 30 Angus and Hereford sired steers, and 70 composite breed heifers. This data will be used for further genetic evaluation and research into feedlot feed intake costs for ultimate use in the U.S. beef industry.<br /> <br /> 3. A prototype genetic evaluation for feed intake in developing yearling bulls and heifers was completed and included 3,000 individuals. This will serve as a prototype for the development of such predictions for selection purposes.<br /> <br /> 4. Genetic evaluations were performed for over 15 different beef breed associations.<br /> <br /> 5. The group continues to discuss better methods for the genetic improvement of reproductive traits in beef cattle. While historically difficult, the melding of quantitative and genomic techniques is consistently discussed as part of the WERA-1 group.<br /> <br /> 6. Identification of effective population size, level of inbreeding, and coefficients of relatedness for all animals registered in the American Wagyu Association. Information to be used by stakeholders for breeding decisions to minimize inbreeding within the breed. Data on association web site and presented at American Wagyu Association national meeting in Reno.<br /> <br /> 7. Results of BVD-PI study conducted on Washington cattle ranches were presented to stakeholders at the annual Washington Cattlemens Association meeting.<br /> <br /> 8. Collection and testing of tissues and feces from dairy cows at slaughter identified a 20% prevalence of bovine paratuberculosis in healthy animals and 85% prevalence in animals with health problems. Information provided back to stakeholders. <br /> <br /> 9. Identification of loci associated with bovine paratuberculosis, bovine respiratory disease and bovine viral diarrhea.<br /> <br /> 10. Worked with the National Animal Genome Research Program to establish a Brangus breed repository. Also to analyze the historic Brangus pedigree file to determine inbreeding rate and the number of families, which will help guide the development of the repository. <br /> <br /> 11. Plans are to use initial information to help build/further develop the Brangus repository. <br /> <br /> 12. First draft of WERA1 Phenomics/Genomics database is complete. Plan to expand for next year. <br /> <br /> 13. GrowSafe system at the Sustainable Agriculture Research & Extension Center (Wyoming) used to conduct bull tests for producers and the university. Plans to develop a Hereford bull test to start next year.<br /> <br /> Short-term Outcomes:<br /> <br /> 1. Increased knowledge of beef cattle feed intake and the underlying genetic variability contributing to differences in feed intake.<br /> <br /> 2. Continue improvements to a web-based decision support system for the beef cattle industry. The system is designed to be used by producers to evaluate sire selection decisions based on the entire suite of sire EPD and the resulting economic impact of those sires progeny on the enterprise. In the end, the system compares profit or loss of alternative selection and mating choices.<br /> <br /> 3. Begun migration of the current decision support system to a new server (and operating) system while simultaneously adding user accounts for storage of operation-specific information to increase use of the system. Development is ongoing based on input from WERA-1 participants and their constituency.<br /> <br /> 4. Elimination of 80 BVD-PI animals from Washington state cattle industry production chain through diagnostic testing resulting in a direct cost savings of $500,000 (without accounting for the loss of infection of other animals in the herd if these animals remained).<br /> <br /> 5. Elimination of BVD-PI problems from eight herds; on retest this year all animals in previously infected herds were negative.<br /> <br /> 6. Increased knowledge base on loci associated with susceptibility to disease in bovine paratuberculosis, bovine respiratory disease and bovine viral diarrhea.<br /> <br /> 7. Increased knowledge base on genes associated with feed efficiency in cattle.<br /> <br /> 8. Dissemination of feed intake and feed efficiency measures to producers through utilization of GrowSafe systems for bull tests and research purposes.<br /> <br /> Outputs:<br /> <br /> 1. Presentations were made to approximately 200 producers in 2009-2010 to disseminate information.<br /> <br /> 2. Two peer reviewed articles, six scientific abstracts and two proceedings papers were published from Texas A&M. <br /> <br /> 3. Talks (CSU and WY): Genetics of reproductive traits; and Current genetic evaluations for reproductive traits in the U.S. National Beef Cattle Evaluation Winter Workshop Series (Denver); CSU Beef Breeding and Genetics Activities, Extension Research Review and Beef Team Meeting (Fort Collins); New Tools for Genetic Improvement, Colorado Cattlemens Annual Convention (Colorado Springs).<br /> <br /> 4. Patent application has been filed for loci associated with susceptibility to bovine paratuberculosis at WSU.<br /> <br /> 5. Three peer-reviewed publications on loci associated with bovine paratuberculosis published from WSU.<br /> <br /> 6. Presentation of results from six abstracts at the American Association of Animal Science national meeting (Denver), three abstracts at the Plant and Animal Genome meeting (San Diego) (WSU; UW). <br /> <br /> 7. Invited presentations on bovine paratuberculosis and animal welfare in Oslo, Norway.<br /> <br /> 8. Awarded world patent on genetic markers of schizophrenia (WO 2006/072075 A2) at WSU.<br /> <br /> 9. Committee information posted on Facebook.<br /> <br /> Activities:<br /> <br /> 1.

Impact Statements

1. Effective outreach and communication to beef producers through peer reviewed publications, bulletins, and direct interactions among beef producers, extension personnel, and scientists. This includes working closely with many breed associations and their members.
2. By developing the ability to conduct a phenomics focus, the group will share resources to efficiently maximize research efforts and training of students and extension personnel, as well as delivering improved tools to breeders. Most importantly, involvement in phenomics-based research fosters collaboration among scientists and increased productivity.
3. Focus on phenomics allows for information exchange and review of ongoing research to prevent duplication of efforts which maximizes use of limited research funds.
4. Involvement in phenomics research encourages cooperative research efforts that require scientists with varied expertise (i.e., quantitative and molecular genetics).
5. Collaborative/cooperative research efforts involving phenomics will lead to grant proposal development among committee members.
6. Information exchange will occur within the committee because of the knowledge of other members academic and research activities. This knowledge will also facilitate cooperative efforts in research as well as student training and extension activities.
7. Attendance at the annual meeting will also yield detailed planning efforts for workshop/producer training efforts. This direct interaction allows the committee members to effectively discuss how to create programs to aid producer decision-making relative to using genetic evaluations and (or) molecular markers for economically relevant and indicator traits.

Impact Statements

1. Effective outreach and communication to beef producers through peer reviewed publications, bulletins, and direct interactions among beef producers, extension personnel, and scientists. This has included working closely with many breed associations and their members, National Cattlemens Beef Association, and regional cattlemen and Stockgrowers associations.
2. Establish collaborations between members. Examples include joint projects between Washington State University and Colorado State University (respiratory disease); Colorado State University and University of Wyoming (high altitude disease); Texas A&M and Washington State University (BRD); University of Alaska and USDA (bear genome).
3. Oversee DNA bank collections and databases for phenotyped populations.
4. Facilitate information exchange among members. Each member brings unique expertise to the group. Members benefit from that expertise, and several projects have been initiated or re-focused as a result of the expertise provided by WERA-1 members.
5. Help students develop networks. As members of WERA-1 interact so closely, their graduate students (and undergraduate students) are better able to develop networks among professionals to advance their educational and career goals.
6. Advance student education. Most members of WERA-1 teach undergraduate and graduate breeding/genetics courses; all members are involved in some aspect of student education and training.
