A range of trials have been conducted at various sites within Kwa-Zulu Natal in South Africa where the product was originally developed and now in commercial use for over three years. In all trials both AfC Tonic and AfC Barn Spray were used in conjunction. AfC is the product name used in South Africa.
These results below are documented in line with standard performance measurement formulae, common in the poultry industry. Where:
· Percentage mortality rates of the chicken batch (the lower the better)
· Chicken weight measured at given days. Six weeks (or 42 days) is regarded as the maximum life span for broiler chickens.
· Feed Conversion Ratio (FCR), which is the ratio of feed, consumed to weight gained by the chickens during their life span. The lower the FCR value, the better.
Performance Efficiency Factor (PEF) is the over-riding measure of profitability used in the industry. (PEF = av. bird weight x %survivors ÷ FCR ÷ age in days)

Products that have been used on other animals include Tonic+, Spray+ and Protect+ either individually or together. Tonic+ and Emvelo Granules ensure a healthy gut whilst Spray+ is used to balance and control the immediate environment in and around livestock housing. With reduced ammonia levels and a sweeter smell these sprays promote a positive living and breathing environment. To complement these we have Protect+, a topical application to the skin, which deters flies and biting insects.
