Check stock for mineral deficencies

AS TUCKER in the paddock turns to dust and supplementary feeding begins abnormally early, farmers are looking to preserve their core herd after destocking the culls.

Most sheep producers have moved from lambing into early weaning this dry season, and Agriculture Victoria senior veterinary officer Paul Beltz, said it was essential to consider whether there are any nutritional deficiencies occurring as tough times set in.

“Deficiencies will impact livestock health right now and production next year, including weight gain in weaners and fertility in rams and ewes if they are not in good condition or have trace element deficiencies.

“Firstly, are the stock getting the energy, protein and fibre they need to stay healthy and grow and are they getting the minerals and vitamins they need to thrive?”

Some commonly seen issues in dry seasons are:

Grain supplementation and grazing cereal crops is known to have low calcium, so calcium supplementation through limestone or lick blocks is essential

Poor pasture growth will impact the “biome” or mix of bacteria in the rumen and may lead to various deficiencies including vitamin B1 or “stargazer’s disease”, and

Selenium (white muscle disease) and copper (swayback) deficiency are known to occur along coastal areas.

Mr Beltz said mineral and trace element deficiencies could be diagnosed through a combination of feed tests, soil tests, blood screening and necropsies where abnormalities are identified.

“To make the best decision, identify if you have an issue then figure out the best way to fix it.

“Remember that trace elements can be toxic if their levels are too high or low, so work with your consultant, nutritionist or veterinarian to ensure you have the right information.”
