SIREMAX reports LAMBPLAN analyses as Expected Progeny Differences (EPDs) for each trait. EPDs are the values most recognized by North American livestock producers. EPDs are also expressed in pounds for Weaning Weight and Post Weaning Weight, and in inches for Post Weaning fat (Pfat) and Post Weaning Eye Muscle Depth (Pemd).

These charts and tables report Siremax flock averages. Please bear in mind that rams offered for sale exceed these averages.

Notes:

• WWT estimates the genetic difference in liveweight (pounds) between animals at 100 days of age. Weight taken at weaning (mid-July).
• PWWT estimates the genetic difference in liveweight (pounds) between animals at 225 days of age. Weight taken at scanning (October 1).
• PFAT estimates the genetic difference in fat depth (inches) at the 12th rib between animals at 100 pounds liveweight. At scanning (October 1).
• PEMD estimates the genetic difference in eye muscle depth (inches) at the 12th rib between animals at 100 pounds liveweight. At scanning (October 1).
• YWT "yearling weight", a higher YWT value ram will produce faster growing progeny.
• Carcase + Index is the main terminal sire index used by Lambplan clients. Relative emphasis consists of 60% PWWT, 20% PFAT and 20% PEMD.
• Counts: numbers of Siremax lambs recorded and added to Lambplan database each year.
