Pedigree beef cattle breeders who record with the Signet Beefbreeder service have their records analysed by a Best Linear Unbiased Prediction (BLUP). BLUP uses the records (weights and measurements) that have been recorded, for the individual and related animals, to determine the likely performance of an individual’s progeny. The analysis calculates Estimated Breeding Values (EBVs) for several traits of economic value, which are the assessments of genetic merit of the animal. EBVs are calculated for 200 day weight, 400 day weight, fat depth, muscle depth and muscle score. An economic assessment, or index, is calculated using this data, called the Beef Value. The objective of this experiment was to compare the performance of dairy-bred beef calves sired by bulls with either a high (top 10% of breed) or below average (bottom 25%) Beef Value.
