Abstract

The effect of fermented wheat germ extract (FWGE, Immunovet-HBM) was studied in chickens challenged with Mycoplasma gallisepticum. Ninety M. gallisepticum- and M. synoviae-free 3-wk-old chickens were exposed to aerosol infection of M. gallisepticum. One group (30 birds) was treated with FWGE, a second group with tiamulin, and a third group was untreated. The fourth group was exposed to PBS aerosol as a negative control. On d 9, all chickens were slaughtered and examined for the presence of gross and histological lesions, the presence of the challenge strain in the organs and specific antibodies in the serum. Body weight gains and feed conversion rates were recorded. In the groups treated with FWGE and with tiamulin, the chickens remained clinically healthy: their BW gains were 441.7 g and 446.8 g, respectively. Feed conversion ratios were 1.72 and 1.71 for FWGE- and tiamulin-treated birds, respectively. Control birds had BW gain of 480.8 g, and feed conversion ratio of 1.78. The numbers of birds with gross lesions (15 and 11, respectively) and lesion scores (25 and 25, respectively) of the FWGE- and tiamulin-treated groups were significantly lower than in the infected untreated group (25 birds, lesion score of 190). No mycoplasma was reisolated from brain, liver, spleen, heart, or kidneys of the FWGE-treated birds, and the number of mycoplasma isolations from the respiratory tract samples was less frequent (10) than from the infected untreated group (64). In addition, 35 samples from other internal organs were also positive. Twenty percent of the birds treated with FWGE showed serological response with a 5.0% reaction score, whereas in the infected untreated group, 83.3% of birds were reactors, with a 62.5% reaction score.
