Aiming at developing a tool for assessing the magnitude of farm animal health, an indicator named herd “animal health status” was built. To illustrate the construction of the indicator, serum samples were taken from 923 goats on 17 goat farms in the state of Sao Paulo, Brazil, where three diseases were evaluated along with their impact percentages: caprine arthritis encephalitis, toxoplasmosis and neosporose – all of an infectious and transmissible nature and the cause of considerable economic losses. The mathematical rationale underlying the building of the “animal health status” indicator ranks properties on a 0 - 100% scale in terms of disease positivity in the herd, with the lowest indicator value indicating the highest cumulative disease frequency (0% = all animals tested positive for the three diseases, 100% = all animals tested negative for all diseases). Anti-T. gondii, anti-N. caninum and anti-CAEV antibodies were tested using indirect immunofluorescence reaction (IIFR ≥ 16), Neospora agglutination test (NAT ≥ 25) and agarose gel immunodiffusion (AGID positive or negative), respectively. The animal health status of the farms ranged from 32.38% to 96.40% according to disease positivity. The animal health status value will have a direct reflection on the production chain both on and off the farm, providing not only great market advantages, due to how the expression of animal health will add value to livestock farms, as well as on the consumer who can check the quality of animal health at the beginning of the production chain.
