Causmag Spreaders & Milk Fever.

Milk Fever is the most common metabolic condition that usually occurs around three days either side of calving. In the early lactation stages, a high producing cow’s calcium requirements exceed her ability to mobilize calcium reserves (bones) and absorb enough calcium from the diet.
Milk fever may be seen in cows of any age but it is more common in high producing dairy cows over five years of age. It can be recognised by the following symptoms.
● Staggering
● Lying down with head and neck kinked back
● Tremors
● Hypothermia
● Constipation
Please contact your vet if concerned your cows may have these symptoms.

WHEN IS IT MOST LIKELY TO OCCUR?

Magnesium supplementation is needed to prevent hypomagnesaemia (grass tetany-staggers) and milk fever (when calcium is also low) in beef and dairy cows from calving to peak milk production.
Apparently Angus and Hereford breeds are more susceptible to grass staggers, (aggression, shaking and sudden death) and dairy breeds are more susceptible to milk fever (down, quiet cow around calving).

PREVENTION USING A CAUSMAG SPREADER.

As magnesium cannot be stored by the cow, magnesium supplementation must begin at least two to three weeks before calving and continue daily until peak milk, realistically six to eight weeks after calving. The length of supplementation will depend on your calving spread and the season.
Pasture dusting with magnesium oxide (causmag) or supplying causmag to fed hay or silage pre- and post-calving are methods that can work well.
It can also be added to drinking water but when magnesium is added to water and dosage is not accurate there is a risk of the water becoming toxic and stock refusing to drink.

WHAT IS CAUSMAG?

Causmag is a reactive calcined magnesium oxide, produced under closely controlled conditions. It is a finely divided white powder with consistent particle size and high reactivity.
Magnesium has a role in metabolism, formation of bone and teeth as well as maintenance of nervous function. It is used as an addition to stock feeds, medicated mineral stock blocks.
Magnesium is needed to activate calcium absorption-resorption and so the two are neatly intertwined.

WHAT ARE THE ISSUES TO BE AWARE OF?

Pasture dusting is really restricted to calving cattle behind a wire or small paddocks, and is challenging on wet and windy days.
Remember, fertilizer products are extremely corrosive. Be sure to wear proper eye, hand and body protection when working on or operating your fertilizer spreader. Also ensure you carry out proper cleaning and storage of your spreader to help prolong the life of the machine and ensures more precise and accurate spreading.
Each season, before heading to the field with the spreader, perform an inspection to ensure it is safe and mechanically sound to operate. Any worn or damaged spreading components could result in inaccurate rate applications and uneven spread patterns. These components should be replaced as necessary.
