LATEST GENETIC TRENDS FOR THE JERSEY BREED
The following genetic trends for UK pedigree milking Jersey cows have been provided by AHDB. These indicate the direction the UK’s Jersey herd is going in for production, health and functionality traits, as well as one of the UK economic indexes the Profitable Lifetime Index (£PLI). Remember; Although positive trends are generally favoured, the only traits where negative figures are desirable are Somatic Cell Count (SCC), Mastitis and Maintenance. With regards to type traits, linear traits have optimal values around 0 whereas the composites (Feet & Legs, Mammary and Type Merit) are favourable when the values are positive.
