Forage brassicas are simply an amazing, low cost feed for our ruminant species.

Over 300,000 ha of brassicas are planted in New Zealand annually and thankfully, animal health disorders are not particularly common despite the huge numbers of animals that eat brassicas each year.

Very occasionally, grazing animals might experience an animal health disorder called SMCO toxicity. SMCO is a non-protein sulphur-nitrogen compound that sometimes accumulates in brassica crops and brassica weed species. Most cases of SMCO toxicity are seen when animals graze forage brassica crops during late winter and early to mid spring (August, September, October in New Zealand) when plants are undergoing fresh growth and reproductive development with increasing daylength and warmer, spring days. Cases present with signs associated with haemolytic anaemia, including red water (red coloured urine).

Presented by New Zealand veterinarian and nutritionist Dr Charlotte Westwood, this podcast takes us through all you ever wanted to know about SMCO toxicity. Because prevention is better than cure, the podcast focuses specifically on how to reduce risk of SMCO toxicity in your grazing animals.
