Calving ease and muscle depth have come top in a survey looking at how beef and sheep farmers use estimated breeding values (EBVs) in breeding programmes.
Also of importance were scan weight, eight-week weight and maternal ability for flocks and mature calving ease, growth weights and scrotal circumference in cattle, with docility also taken into account.
This is according to a survey of Signet traits in an AHDB Beef and Lamb-funded survey, which showed a trend for sheep farms to select for lamb growth rates and ewe milking ability. Meanwhile, beef producers focus on calving ease and later calf growth rates.

Signet breeding manager, Sam Boon said: “New beef traits such as docility and scrotal circumference appear to be in demand, although a degree of caution is required here as neither trait is produced for every beef breed.
“Breeders are placing noticeably less emphasis on fatness within their selection decisions, indicating the progress made in avoiding overfat lambs through improvements in growth rate and the consequential need to optimise selection for leanness/fatness within sheep and beef breeding programmes; a feature already embraced in most modern breeding programmes.”
