The New Zealand Deer Industry Productivity Strategy 2009-2014 (Deer Industry New Zealand, 2009) aims to increase deercarcass weight by 10% and introduce a carcass yield module to their performance recording database DEERSelect. In other livestock species real-time ultrasonography offers a non-invasive, non-destructive, standardised muscle measurement on live breeding stock (Faulkner et al.,1990). Ultrasound scanning allows eye muscle (M. longissimus dorsi)dimensions and cross-sectional area to be recorded as traits for genetic evaluation in the Sheep (SIL) and Beef (BREEDPLAN) performance recording databases.
