Credence is a sanitiser and disinfectant with great broad spectrum efficacy against bacteria, fungi and viruses, including rotavirus, M. bovis and Salmonella spp. Please see the research attached on the product page. We do not sell the product – order online from Animal Health Direct in Hastings, NZ. Much more human and animal friendly than alternatives, low smell, can be safely used in calfeteries and in drinking water (at the correct concentrations). Clean down calving shed beforehand to negate any pathogens lurking in dirty corners and wooden posts. During rearing, make sure you have foot and wheel baths in place (a piece of soaked foam rubber is an easy way to create a wheel bath) and hand dips for everyone on site.
