18/06/2018: Natural vs chemical coccidiostat

by Growell, India

Coccidiosis continues to be a challenge for poultry, cattle and pig production worldwide.

This singular pathogen causes an enormous economic burden to the industry. Vaccines & chemical coccidiostats (anticoccidials) are widely used with a great variety of results.

Numerous concerns have arisen concerning the use of chemical coccidiosis deterrents, namely that these drugs can enter the wider food chain causing antibiotic resistance as well as other health concerns not limited to adverse effects from exposure.

Though governments have tried to intervene, this article suggests that natural, plant-based anticoccidials can safely replace chemical deterrents, thus protecting human and animal health and saving billions for this industry at large while also promoting the sustainability of cattle, poultry, and pig production.

Examples of the published side effects of chemical coccidiostats
Before describing the solution that may be possible in natural anticoccidials, it is helpful to look at the problem of chemical anticoccidials with more specificity.

It has been suggested that residues of ionophores in food could cause adverse effects on the health of humans. These substances possess potent cardiovascular properties (KabellETAL, 1979; Fahim and Pressman, 1981).

Inotropic effects of lasalocid, the antibacterial drug commonly found in feed additives called Bovatec and Avatec, has been found in vitro, damaging the human heart muscle. (Levy and Inesi, 1974).

Another chemical anticoccidial, narasin, has been found to pass into an egg yolk, meaning the drug will easily pass into human food supplies (Catherman ET AL, 1991).

Yet another, Decoquinate, is only absorbed to a small extent (SemanETAL, 1989) and is reported to have very low toxicity (Fowler, 1995). Low toxicity is also reported for diclazuril (Fowler, 1995), however, Amprolium, may be found in eggs up to 10 days after withdrawal from animal feed (Kan ET AL, 1989).

Amprolium is reported to be fairly atoxic, and it is not permitted in the feed after the beginning of egg laying. Passage of halofuginone into eggs has also been reported (Lindsay and Blagburn, 1995).
