GeneSTAR® MVPs™ lead the industry in DNA-marker technology, incorporating a 56-marker panel for three economically important traits. GeneSTAR MVP traits are the most useful DNA-marker tools for genetic improvement to date. The product provides Molecular Value Predictions for the core traits of Feed Effciency, Marbling and Tenderness. The GeneSTAR® MVP™ provides information on the genetic make-up of a particular animal. The table below defnes the traits, units and ranges of results. Interpreting the GeneSTAR® MVPTM Results Tenderness Tenderness is predicted on the basis of the peak force required to shear cooked steak after 14 days of post-mortem aging. The MVP for tenderness is reported in kilograms of W-B Shear Force. The less force required, the more tender the piece of meat. Therefore, a lower number is more favourable. Marbling Marbling is a visual assessment of the degree of intramuscular fatness in the longissimus dorsi (rib eye) muscle and is a predictor of overall eating quality. The MVP for marbling is reported as AUS-MEAT marble score. The higher the marbling MVP, the greater the potential for a high AUS-MEAT marble score. Feed Effciency Feed effciency is predicted on the basis of net feed intake (NFI) which measures the difference between an animal’s actual and expected feed intake based on its body weight and growth rate. The MVP for feed effciency is reported in kilograms of feed consumed per day compared to the predicted required feed intake in kilograms. A more economical animal is one that eats less in order to achieve an expected growth rate. Therefore the lower the MVP result the better. NEW Summary of Results Sheet -- The Stars are back! Now, when you receive your GeneSTAR MVP results, you will also be given a Summary of Results Sheet which effectively explains the results of your animals, using their percentile ranking compared with other animals (within breed or comparable population). This summary is a visual representation of results and offers both the owner and potential purchaser of that animal an easy snapshot of an animal’s genetic potential. This summary will be shown as the following: Where: At the forefront of DNA technology Less Favourable Top 100% Top 90% Top 80% Top 70% Top 60% Top 50% Top 40% Top 30% Top 20% Top 10% Top 5% Top 1% Most Favourable 1300 768 400 | www.pfizeranimalgenetics.com.au Health.
