What the research shows

A study in newborn Holstein calves found that adding natural zeolite clinoptilolite to colostrum and milk at an appropriate dose reduced the incidence and severity of diarrhoea, while higher inclusion rates were linked with poorer outcomes. (DOI: 10.1016/j.livsci.2007.08.010)
A trial in neonatal dairy calves found that supplementing colostrum with clinoptilolite increased serum gamma-globulin fractions and improved passive transfer markers, with the lower inclusion rate performing better than the higher rate. (DOI: 10.3390/molecules23061278)
A review of natural and synthetic zeolites in animal feeding reported that these materials have been used to help manage farm animal health challenges because of their ion-exchange and adsorptive properties, including binding unwanted compounds and influencing gut conditions. (DOI: 10.1016/j.micromeso.2005.05.030)

Limits

These studies assess natural zeolite or clinoptilolite in calves and broader animal nutrition settings, not this specific product or its exact North Island BPM zeolite source and feeding programme.

Study details and links

What was tested

Research on natural zeolite use in young calves, including a calf diarrhoea study using clinoptilolite in colostrum and milk, a neonatal calf study on passive transfer after colostrum supplementation, and a review covering how zeolites have been used in animal feeding and health management.

What was measured

Diarrhoea incidence and severity, passive transfer indicators including serum protein fractions and gamma-globulins, and the reported functional roles of zeolites in animal nutrition based on their adsorptive and ion-exchange characteristics.

More detail on limits

The evidence supports the use of zeolite-based calf health strategies and ingredient functionality, rather than proving the performance of Optiguard North Island as a branded product on its own.
Results can vary with zeolite type and purity, dose rate, calf age, colostrum management, milk-feeding system, pathogen load, hydration and electrolyte management, and the wider calf-rearing environment.
