Their 'valuation' figures are a mish mash of auction ring sales of various categories of stock over previous weeks, but therein lies the problem.
Prices for livestock dipped sharply in the latter part of the summer, due to restrictions of the bluetongue zones. But in the late summer, a shortage of decent quality dairy cattle, pushed up prices. Considerably. And Defra's tables are not constructed on a like for like basis - nothing so simple. Non-pedigree animals have a one month bracket of calculation, while pedigree values are tabulated from prices over the previous six months.
