Lean Meat Index Growth Explanation
Lean Meat Growth Index:
At an age between 100 and 150 days, the lambs weighed and scanned. The weight is determined, and simultaneously with an ultrasound scanner, a photo of the back muscle made. The scanner can perform measurements at several points that are visible on the screen. This method is an indication of the total volume amount of lean meat in the animal. The reliability is more than 70%. It is in view is far from feasible.
After the digital delivery of some data of individual animals, the data processed by ISG to Lean Meat Growth Index (MVG). The weight is with the birth data processed in a marked growth. This growth is corrected to an animal, "as it would weigh 40 pounds.
This is also done with the fat and muscle thickness. These numbers are all to a "standard lamb" of 40 kilos converted. The index provides a summary of the growth, fat cover, Muscle Thickness.
The index-based on the average of the years 2007 - set at 100.
MVG The index consists of the following elements:
- Toetsdag Age: The age of the animal in days on the day of scanning and roads
- Vet40: mm back fat in the animal would be counted as 40 kilos
- Fat toetsdag: actual fat in mm on the day of weighing and scanning
- Spier40: muscle thickness in millimeters calculated back as if the animal is 40 kilos
- Muscle toetsdag means actual muscle thickness in millimeters on the day of weighing and scanning
- Groei40: average growth per day in grams to 40 kilos in weight
- Toetsdag growth: average growth per day in grams
- Leeftijd40: number of days that the animal (back included) needed to achieve weight 40 kilos
