UPDATE: Feeding standards set for national change

NATIONAL standards used to predict energy requirements and intake for sheep are being evaluated to improve the accuracy of on-farm economic predictions for sheepmeat producers.

Meat & Livestock Australia is leading the research and development project addressing components of the Australian Feeding Standards for Ruminants, the national standards which describe the nutrient requirements and the response of ruminants to changes in their feed supply.

The project is being undertaken in collaboration with Murdoch University, the South Australian Research and Development Institute and Agriculture Victoria at Hamilton.

MLA Program Manager - Sheep R&D Richard Apps said the project would redefine key aspects of the AFSR related to intake capacity and energy use for non-Merino or maternal ewes.

"The AFSR in their current form were developed from Merino-based systems but don't work for modern maternal genetics," Mr Apps said.

"Lambs from non-Merino or maternal ewes are an important part of the sheepmeat industry, accounting for about 40-45 per cent of total lamb supply.

"The AFSR need to be redefined to accurately determine the economic optimum condition score profiles for a range of production systems.

"The new feeding standards we're working on will be a long-term enabling tool for the sheep industry when doing on-farm modelling to help boost productivity and profitability."

Mr Apps said the project would complete research and development work already undertaken by MLA through the Lifetime Maternals project, which developed management guidelines for non-Merino ewes, aimed at lifting lamb survival, weaning rates and kilograms of lamb produced per hectare in maternal ewe flocks.

He said some of the findings of the Lifetime Maternals project highlighted the need to redefine AFSR.

The new LifeTime Maternals tools are expected to be available to the sheep industry by the end of 2018.
