Abstract Limited transfer of existing and emerging reproductive technologies to beef cattle enterprises precludes those enterprises from reaching their economic potential and places them at a competitive disadvantage relative to livestock enterprises where such technologies are being implemented more aggressively. On the other hand, and until now, the beef cattle sector has never had the reproductive tools available to facilitate widespread successful adoption of these technologies within the industry. Hence, the need for increased efforts to transfer technology to the industry has never been greater. The National Center for Applied Reproduction and Genomics (NCARG) in Beef Cattle will serve as a new model for research and technology transfer wherein industry participants at all levels and from across the US are afforded the opportunity to access information and acquire new skills that will improve reproductive management and resulting genetic makeup of our nation’s beef cattle industry. Comprehensive educational training programs will be developed for practicing veterinarians, extension livestock specialists, allied industry, producers, and students that will enable various segments of the beef cattle sector to acquire (through face-to-face and distance-learning applications) new knowledge and skills that will aid in the successful adoption of reproductive procedures/biotechnologies. Curriculum modules designed to support improvements in reproductive management will be comprised of the following: 1) Heifer development programs including reproductive tract scoring, fetal aging and sexing; 2) Breeding management, including estrus synchronization, artificial insemination, sex-sorted semen, and embryo transfer; 3) higher education student internships in reproductive management; and 4) on-farm beef heifer development and marketing programs patterned after the Missouri Show-Me-SelectTM Replacement Heifer Program. In addition, a graduate certificate program will be offered, entitled “Bovine Reproductive Management and Genomic Technologies.” Collectively, NCARG will serve as a new model for research and technology transfer intent on improving reproductive management and genetic makeup of our nation’s beef industry.

A survey was conducted to document general characteristics of beef cattle management and identify producer concerns in Manitoba. The survey was divided into five sections: (i) characterization of farm operation, (ii) winter management, (iii) forage and pasture management, (iv) reproductive management and (v) factors limiting profitability and the use of non-traditional management tools. The surveyprovided base information for measuring change in the industry and identified cost of production, pasture, and reproduction as the top three factors that producers consider limiting the profitability of beef operations in Manitoba.

SUMMARYEscherichia coliO157.H7 was found in 10 of 3570 (0·28%) faecal samples from dairy cattle in 5 of 60 herds (8·3%). Several tentative associations with manure handling and feeding management practices on dairy farms were identified. Faecal/urine slurry samples, bulk milk samples, and milk filters from dairy herds were negative forE. coli0157.H7.E. coli0157.H7 was also isolated from 10 of 1412 (0·71 %) faecal samples from pastured beef cattle in 4 of 25 (16%) herds. The prevalence ofE. coli0157. H7 excretion in feedlot beef cattle was 2 of 600 (0·33 %). The identification of cattle management practices associated with colonization of cattle byE. coli0157.H7 suggests the possibility that humanE. coliO157.H7 exposure may be reduced by cattle management procedures.

Order Of Magnitude

In recent years, producers have combined the use of phenotypic appraisal and the estimation of breeding values (PTA or EPD) to make genetic selection decisions in beef and dairy cattle that have resulted in a steady genetic gain of 2% per year. However, the most extensive application of genomics has occurred in dairy with the estimation of molecular breeding values that has increased selection efficiency to a much higher order of magnitude. Despite a growing molecular and physiological understanding of complex traits, little is known about the genes determining the traits and their precise function, and a significant unexplained source of variation of phenotypes remains in livestock. Within this context, a more complete understanding of the genes and regulatory pathways and networks involved in economically important traits (i.e. feed efficiency and methane emissions, meat quality and carcass traits) in beef cattle will provide knowledge to help improve genetic selection and reproductive management. Therefore, high throughput -OMICS technology (i.e., transcriptomics, metagenomics, metabolomics, as well as epigenetics and gene networks amongst several others), will complement these tools and further advance identification of functional genes within a systems biology approach.
