The comprehensive Analytical Laboratory to Southern Africa


Chemical Analysis

CAL provides a broad range of proximate and nutritional analysis to satisfy most requirements for feed and raw material nutrient profile descriptions.

Mycotoxin Analysis

Mycotoxins are toxic secondary metabolic products of fungi present on almost all agricultural products. Mycotoxins are produced by different strains of fungi, and more than one toxin can be produced per strain.

In-Feed Medication Analysis

In line with the responsible use of in-feed medications CAL has worked closely with its customers to develop a broad and definitive analytical service for a range of active compounds.

Soya Quality Analysis

Soya beans and their products are valued due to their high quality, especially with respect to protein and its amino acid profile. In their untreated form soya beans contain a number of factors that diminish their nutritional value.

Forage Analysis

CAL offers an all-encompassing forage analysis service. Clients are spoilt for choice between wet chemistry analysis, locally based NIR calibrations, and internationally recognised Dairyland Laboratory NIR calibrations which provide results in an AMTS format.

Near Infrared Spectroscopy Analysis

Near Infrared Spectroscopy (NIR) provides a rapid routine analysis of raw materials and finished products. NIR allows for the prediction of multiple nutrients in a fast and cost effective way.

Water Analysis

Water is a critical but often overlooked nutrient for livestock and poultry. CAL offers three package types which cover most of our customers’ requirements. Please note CAL does not do result interpretations.

Serology / Diagnostics

The diagnostic identification of antibodies in the serum of Avian blood utilising ELISA and agglutination based testing. Antibodies are typically formed in response to either the vaccination or the infection of the bird in question.
