China's demand was increasing, but not at the near-term pace of this competing supply, he said.
"We expect cattle numbers in the coming season to be similar or slightly up on this season, with some of the retentions out of the dairy herd last year expected to boost bull and even heifer numbers," Hamilton said.
For lamb, China and US demand was strong.
"In October we will head into the European chilled supply season which should hold up farm gate prices," he said.
"Once through that, we expect the total return from lamb to decrease given the greater frozen mix.
"We would normally see a $1/kg rule of thumb difference in value from the Christmas chilled period to the main part of the season - everything else being equal."
Silver Fern expected lamb numbers to be up this coming season.
"All the feedback we are receiving is that the North Island in particular has seen good lambing," said Hamilton.
"Volumes may well be up 5 to 10 per cent through 20 million lambs nationally processed next season.
"Venison markets remain very strong given the lower supply out of New Zealand.
"Market prices in Europe and the US remain up on last year, and new premium trim markets in the US are adding to the overall value being realised. "We see a continuation of these current market conditions."
Hamilton said he expect processed venison numbers to be similar to the current season at around 280,000 - 300,000 as the national herd continues to slowly rebuild.
