As a Producer,How Do I Hit that Target? Twig Marston Extension Beef Specialist K-State Research & Extension
“Ideal” Carcass Specifications • Hot Carcass Weight 700 to 800 lb • External fat 0.3” to 0.4” • Loin Eye Area 12.0 to 14.0 sq. in. • Marbling Small 00 minimum – Modest 00 preferred • Genetically “Guaranteed Tender”
Goals Set for 2005 from National Beef Quality Audit - 2000 • Eliminate USDA Standard grade carcasses. • Eliminate Yield Grade 4’s and 5’s. • Eliminate side-branded hides. • Accompany all seedstock animals with meaningful genetic data for production and end-product traits. • Continually improve the eating quality of beef.
Defining Quality • Consumer – Affordable, lean, tasty, and tender • Retailer – Trim, tasty, uniform in size and tender • Packer – Finished cattle of the proper weight, quality grade and yield • Feeder – “Good Doing” cattle w/ growth potential, the right weight, quality and yield • Producer – Genetically correct cattle, efficient in reproduction, growth, and adequate marbling
Producers’ Tool Box • Genetics • Nutrition • Management • Advertisement/Education
Heritability Estimates • Fat thickness 0.19 • Marbling Score 0.68 • WBSF 0.40 • Taste Sensory Panel • Tenderness 0.37 • Juiciness 0.46 • Flavor 0.07 Dikeman et al., submitted
Marbling, Favor, Juiciness, and Tenderness • Breed composition • Diet energy concentration • Length of the finishing phase
Breed Differences Exist Black is not a Carcass Gene, It is a Dominant Coat Color Gene.
Why Do We Need Marbling? • Flavor • Insurance for Ignorance in Cooking
Marbling(Producers’ Insurance Policy) • About a 10% linear increase in consumer acceptance for each full marble score between Slight and Slightly Abundant. • WBSF between 6.6 and 12.1 correlated to a steep decline in predicted acceptance. Platter et al., 2003 CSU

DNA Marker Assisted Selection • Eating Quality Test • Disease Resistance • Marker–Assisted Expected Progeny Differences • Global Efforts – Australia, Brazil, Canada • Calpain (good guy) propagate and • Calpastatin (bad guy) eliminate
Nutrition • Grain vs. Grass-fed vs. Forage-fed • Weaning Age/Young Age Positive Energy Balance • Propionate vs. Acetate VFA Rumen Production • Creep feeding
Management • Implant and Implant Programs • Feed Additives (Beta agonists) • Calf vs. Aged Cattle Feeding • Days on Feed

Three Paradigms of Beef Producers • Cattle Producer • Labor user, task-driven, no effective use of information • Red Meat Producer • Record keeper, cost efficient, focused on red meat • Food Producer • Complex, targeting product characteristics which are multi-dimensional and directly related to known tastes and preferences of consumers
The Future of the Paradigms • Cattle Producer – will be around because of the love and romance of the business, will stay in business if not over leveraged. • Red Meat Producer – will survive with the commodity side of the business. • Food Producer – will be rewarded by those that know the value of quality. Driven by the cost and quality controlled production of food made from beef.
Quality Thoughts • We can now make more mistakes faster than ever before. • Those who refuse to use data will make greater and more frequent mistakes. • Those who refuse to make data will be compensated with a smaller piece of the pie. • Those who control the data control the destiny of the industry.
