This study investigated the functionality of horse innate defense mechanisms under the influence of raising technologies. This evaluation was conducted on three experimental groups: group I (horses from a semi intensive farm), while group II and III included horses raised in extensive conditions and cohabitating with bovine and bovine and pigs, respectively. From each animal, blood was collected by jugular vein puncture and the serum samples were processed for the evaluation of total immunoglobulins and immune circulating complexes. Two nephelometric tests were carried out: zinc sulphate turbidity assay for the total protein concentration (Serb method) and the 4.2% polyethylene glycol (PEG) precipitation technique in order to estimate the level of the circulating immune complexes (CIC). The monitoring of the results obtained for the total immune globulins indicated lower values for the animals raised in shelters along with others species when compared to the animals grown under semi-intensive conditions. There was no statistical significance of the differences for the obtained results. The CIC were reduced for the intensively raised horses when compared to groups II and III, while the differences between groups II and III were statistically non significant. The lowest value of CIC, recorded for the horses belonging to group III, indicated the influence exerted by the raising conditions, the overcrowding induced stress and the housing and microclimate conditions on this parameter.
