The rapid depreciation in the Australian dollar over the past three weeks has been beneficial for export processors and producers alike, helping to keep cow prices high, according to Meat and Livestock Australia.

MLA reports that demand for cows has strengthened considerably, even though supply has also increased.

Quality has been mixed at most centres, although there have been some well finished cows, which have come off crops in northern NSW.

MLA says national cow supply rose by 9pc, with numbers selling to slaughter 17pc higher than the previous week.

The large yarding of nearly 1000 cows at Dubbo was an influence.

MLA says cow prices have been strong since late May, due to strong international demand for manufacturing beef and typically lower winter supplies.

The national US cow indicator was firm this week, at 140¢/kg (live); and is at the highest point since the same time last year, when the winter price peak reached 142¢/kg.

Southern prices are largely driving the market, with the Victorian price up 8¢/kg and the SA indicator 6¢/kg dearer, at 156¢/kg and 152¢/kg respectively.
