New Zealand (NZ) lamb production has fallen again to the lowest level in over 60 years to 23.7m for the current lambing season, according to Beef and Lamb New Zealand.This comes on the back of declines last season, when 24m lambs were born, and the previous year when 25.58m lambs were born. This is a dramatic fall from an industry peak in the early 1980s, when the country had 70m sheep, and as recently as a decade ago the number was 39m. Widespread switch to dairy production has led to a decline in the sheep industry.
