Farm-gate prices for lamb and mutton are forecast to average $103 and $79 a head, up $3 on 2013-14 provisional prices.
Davison said that, while total sheep numbers were down on last season, the number of lambs tailed this spring was estimated to be similar to last spring - at 25.6 million - reflecting favourable weather.
"But export lamb production is forecast to decrease by 2.6 per cent, as farmers opt to hold on to more ewe hoggets as replacement breeding stock which is a positive indicator for the sector," he said.
Bull, steer and heifer farm-gate prices are forecast to increase 8.5 per cent.
The value of beef and veal meat exports is expected to rise 5.5 per cent on last season.

Agrifax's beef price index has risen for the past four weeks, and it is now just shy of the record level, set in September 2008.
