Introduction to selecting a ram on EBVs
This website aims to provide the reader with an understanding of how to select rams on performance figures. By selecting on performance figures and utilising the best available genetics, flock performance and profitability can be improved significantly.
Selecting breeding stock with high performance figures is widely recognised as the single most effective tool for increasing economic returns and efficiency of livestock production. Essentially, this is achieved by identifying the best performing animals on weight gain, conformation, and maternal value.
HCC runs a genetic improvement programme supporting breeders to performance record their pedigree animals. Through the Elite Ram Project HCC also provides support to commercial breeders on how to select animals on performance to maximise production and profitability.
Breeding for Profit
A progressive breeding strategy will influence the two main components of flock profitability: lamb output and costs of production.
Lamb output
The breeding potential of the flock will influence the value of lamb produced per ewe, firstly through the ewe’s genes for prolificacy and maternal care and subsequently through the lamb’s genes for growth and carcase quality.
Costs of production
Reductions in labour and housing requirements can be achieved through genetic selection for easier management and health. Reductions in feed and fertiliser can be achieved by enhancing lamb growth rates.
Breeding for Profit
Flock profitability = output - costs
A progressive breeding strategy can influence both factors.
