A brief description of Breedplan and Estimated Breeding Values (EBVs)

       An animal's breeding value is its genetic merit, half of which will be passed onto its progeny.
       These estimates are called Estimated Breeding Values (EBVs).  The absolute value of any EBV is
       not critical, but rather the differences in EBVs between animals.
       Whilst EBVs provide the best basis for the comparison of the genetic merit of animals reared in
       different environments and management conditions, they can only be used to compare animals
       analysed within the same analysis.  Consequently, Limousin BREEDPLAN EBVs cannot be validly
       compared with EBVs for any other breed.
       Although EBVs provide an estimate of an animal’s genetic merit for a range of production traits,
       they do not provide information for all of the traits that must be considered during selection of
       functional animals.  In all situations, EBVs should be used in conjunction with visual assessment
       for other traits of importance (such as structural soundness, temperament, fertility etc).

       Birth Weight (kgs) – estimates of genetic differences in calf birth weight.
       200 Day Weight (kgs) – estimates of genetic differences between animals in liveweight at 200
       days of age.

       400 Day Weight (kgs) – estimates of genetic differences between animals in liveweight at 400
       days of age.

       600 Day Weight (kgs) – estimates of genetic differences between animals in liveweight at 600
       days of age.

       Scrotal Size (cms) – estimates of genetic differences between animals in scrotal circumference
       at 400 days of age.  [Note actual measurement done 16 March 2019.]

       Docility – estimates of genetic differences between animals in the percentage of progeny that
       will be scored as docile or restless (scores 1 or 2).










       The Limousin Assurance Program has the following objectives:
       1. To differentiate Limousin members from commercial breeders who sell unregistered bulls.
       2. To provide members with a uniform method of providing information, assurance and warranties to po-
       tential buyers.


       The basic requirements for members to participate in the Limousin Assurance Program are:
       • All seedstock animals offered for sale are registered or recorded with the Australian Limousin Breeders’
       Society and transferred on request by the purchaser.
       • Each drop of calves are docility scored using the ALBS docility scoring system and the scores are submit-
       ted to ALBS.
       • A prescribed docility warranty is provided for all bulls and females.
       • A prescribed fertility warranty is provided for all bulls and females.
