New Charles Sturt University (CSU) research is investigating the effectiveness of vitamin and mineral supplements for sheep used by NSW producers.

The study, being carried out in partnership with MerinoLink Limited, will examine whether there is value in using certain supplements currently on the market so that producers can make informed management decisions.

Dr Luzia Rast, lecturer in ruminant health and production in the CSU School of Animal and Veterinary Sciences,said the research aims to fill a gap in current knowledge.

"There's anecdotal evidence that producers use a range of supplements for a variety of reasons, from increasing growth rates and fertility through to preventing certain health problems," said Dr Rast.

"However, there's very little or no evidence that the supplements achieve the desired outcomes, nor is there any cost benefit analysis."

MerinoLink Chief Executive Officer, Ms Sally Martin, said, "The use of supplements may make producers feel good but is it making them money?"

Dr Rast said the first step is a survey to identify commonly used supplements which will be followed by field trials in a range of sheep enterprises in southern NSW.

"We are seeking NSW producers with more than 500 sheep to participate by answering a questionnaire that will take around 15 to 25 minutes," Dr Rast said.

The survey is available electronically here. Producers can also obtain a hard copy by contacting Dr Rast on (02) 6933 4233 or by email lrast@csu.edu.au  and Ms Martin on mobile 0400 782 477.

It is one of two projects underway at CSU to receive a grant from the NSW Sheep Industry Fund. Associate Professor in Ruminant Health and Production, Bruce Allworth, also received a grant for his research into iron metabolism in sheep.

Professor Nick Sangster, Head of the CSU School of Animal and Veterinary Sciences, said, "Charles Sturt University is in a unique position because we are able to link our research with teaching in our animal, equine and veterinary science programs based in regional Australia.

"Ultimately, the research aims to improve health and welfare of animals along with the productivity of farm animals."
