So if they’ve got more muscle...
Shouldn’t they be worth more???

So is GR tissue depth the best indicator of
lean meat yield %?

Key terminal sire traits - Sheep
Let’s focus here!
For carcase improvement…
• Growth (PWWT)• Reduced fat depth (PFAT)• Eye muscle depth (PEMD)

Carcase Traits Summary!
• Growth (PWWT)- For heavier carcase
• Reduced fat depth (PFAT)- For leaner carcase
• Eye muscle depth (PEMD)- For more muscle where you need it!
![Page 54: Lean Meat Yield Where the $$$$ are! Graham Gardner.](https://reader035.fdocuments.in/reader035/viewer/2022062511/551bcc92550346af588b525e/html5/thumbnails/54.jpg)
Key terminal sire traits - Sheep
• Growth (PWWT)- For heavier carcase
• Reduced fat depth (PFAT)- For leaner carcase
• Eye muscle depth (PEMD)- For more muscle where you need it!
But how do we combine
them?
