Technical Abstract: In three trials in which commercial layers were utilized to determine the effect of Mycoplasma gallinarum on egg production, fatty liver hemorrhagic syndrome (FLHS) was initially observed in the control hens. In the three trials, FLHS was observed to occur 26 to 42 days earlier in control hens as compared with the hens infected with Mycoplasma gallinarum. In Trials 1 and 2, no therapeutic intervention was initiated and total mortality at th end of those trails was not significantly different between the controls and the hens infected with Mycoplasma gallinarum. In Trial 3, therapeutic intervention consisting of one pound of choline chloride/ton of feed was implemented; however, as in Trials 1 and 2, there was no significant difference in total mortality attributable to FLHS between the two treatments. In each of the three trials, the controls experienced a numerically higher total incidence of FLHS.
