Elders St George livestock trainee Chloe Taylor explores the issue of phosphorous deficiency in cattle, emphasising that it may be a risk for southern producers too.
We are all familiar with the narrative of phosphorous deficiency, particularly within the northern regions of Australia. Despite this, deficiency also poses a threat to many regions of southern Australia as well.
Many pastures in the south have been revealed to be low in available phosphorous as a result of naturally low levels, in conjunction with a decline in fertiliser use in recent decades.
Phosphorus deficiency is a silent killer many are unaware of and presents severe limitations to production. It might be time to review the deficiency status of your area.
Phosphorous deficiency is capable of affecting all demographics of cattle and sheep and poses a threat to many of our primary industries as a result.
Phosphorus is the second most abundant mineral and supports processes such as bone formation and energy metabolism. Phosphorous is vital for growth and plays a role in skeletal development and maintaining bone density. Phosphorous deficiency represents significant costs to production through limitations on yield. To maximise production, all producers should be aware of their phosphorous deficiency status and implement supplement strategies to cater to this. It pays to be proactive in mitigating the signs of phosphorous deficiency.
Producers throughout Australia must be proactive in knowing their status regarding available soil phosphorous and should take the necessary steps to mitigate the signs of deficiency if present. Soil, pasture, and animal health are all potential indicators of potential phosphorous deficiency. Signs of acute deficiency in animals may include poor appetite, reduced growth, and reduced fertility. Managing phosphorous deficiency is also essential as a potential precursor to Botulism.
Fortunately, we are spoilt for choice with supplement options. Licks and loose licks are some of the most accessible options, and a resource which is readily available. Use within wet seasons is an ideal choice for supplementation, however many producers choose to supplement year-round.
If you are unsure of your status regarding phosphorous deficiency, there are measures which can be taken to provide a comprehensive understanding. Contacting your local department of agriculture or accessing resources like local phosphorous maps are ideal indicators to see if you may be at threat. MLA’s Phosphorous Hub is also a great source of information on manoeuvring deficiency, otherwise you can contact your local Elders livestock production specialist.
