Farmers tell us "it is a great preventative and treatment for scours".  

"My calves loved it and still do, rearing late calves can sometimes become an issue with nutritional scouring as not much colostrum left around but "touchwood" no issues".

What damage can diarrhoea (diarrhea) in calves do? Many term this 'Calf Sours'.

Calf diarrhoea is the primary cause of death in calves from 2 to 30 days of age. Preventative measures provide great economical and animal health benefits.

The pathogens causing diarrhoea (viruses, bacteria and microscopic parasites) cause damage to the lining of the intestinal tract.

The cells lining the intestine can be killed by viruses such as rotavirus, bacteria such as E.coli and protozoan parasites such as Coccidia and Cryptosporidium.

The latter can be carried by healthy heifers and cows and are shed into the manure. Cryptosporidium, which is also a threat to humans, is particularly troublesome because no effective treatment nor vaccine is available, despite extensive research.

Bacteria, such as certain strains of E. coli and Salmonella, invade the deeper layers of the intestinal lining, rapidly destroying it.

Calf diarrhoea are usually caused by two or more of these pathogens working together.

When the intestine is damaged by pathogens, the water and nutrients in the milk can't be completely absorbed into the calf's bloodstream. As a result, they may stay in the intestine and provide other pathogens with the nutrients to thrive and at the same times the nutrients are not available to the calf and a large fraction is lost from the calf's body in the diarrhoea. This loss is the greatest threat to the survival of a scouring calf, therefore, it must be a primary treatment focus.

The fluids lost in the diarrhoea quickly deplete the calf of water and salts, producing symptoms of dehydration - sunken eyes, weakness, and dryness to the mouth and nostrils. As the calf loses body fluid through diarrhoea, its blood thickens, making it harder for its heart to deliver blood to its tissues. The loss of body fluid of more than 12% will ultimately lead to death.

What does OptiGuard do to help?

OptiGuard is effective in absorbing some of these scour causing pathogens, such as Rotavirus and E.coli as well as absorbing excess moisture in the digesta, thereby reducing the effects of diarrhoea.

OptiGuard should be used in conjunction with good nutrition and shed hygiene along with appropriate vaccinations and vet recommendations to prevent scouring.

OptiGuard is a premium quality 100% natural, finely milled BPM zeolite that is mined and manufactured locally in the Taupo Volcanic Zone. Natural BPM zeolites have a unique three dimensional porous structure, allowing them to absorb and release water reversibly.  The extensive internal network of pores gives zeolites an amazing capacity to absorb mineral ions and bacterial toxins.

OptiGuard has been specially formulated with a small, finely milled particle size. The ultra-fine particle size of OptiGuard ensures a larger total functional surface, providing a much larger surface-gut environment interface. This allows for more rapid absorption and thus deactivation of bacterial toxins, as well as improved electrolyte and water balance in the intestines

What do OptiGuard users say?

"I had stopped feeding as all our calves were over 1 month old and passed the high risk scouring stage. But one of vats of stored milk went off and all the inside calves got the shits. Normally this could have turned out very badly but I just bulk fed them Optiguard and they were recovered within two days". Sue, Opunake

"I used Optiguard this season for my calves, just feeding ad-lib ina trough in the calf shed. It is the best product I have used for calving. I had the best calves I have ever had, with no scouring or any illness in the shed at all – it’s the first season I can say that."
Lynn, Cambridge

"I used optiguard this season to help me battle a out break of crypto and it sure did what it said it would do.... My girls loved it and sure got into it, I will most definitely be getting some more next season and would highly recommend it to others, so once again thanks guys." Lisa.


Healthy Feeding Calves


How to use OptiGuard?

Four tablespoons of OptiGuard, with its unique 3-dimensional porous structure, has enough total absorbtive surface area to cover a full-sized rugby field.  The ultra fine particle size of OptiGuard provides a much larger surface-gut environment interface, allowing for more rapid absorption and thus deactivation of bacterial toxins.

Simply add OptiGuardTM to your calf-meal mix, or place it directly into feed troughs to allow calves to self-manage their intake. OptiGuardTM can also be mixed with milk. Simply stir to reconstitute.
Addition rates from 10gm per calf, per day – or ad-lib as necessary. OptiGuardTM is available in 20kg bags and 1000kg bulk bags from your local Vet only.
