An experiment was conducted with 120 quails, during their growth-fattening period (1 to 42 days), to study the effect of dietary acetylsalicylic acid (aspirin) on their performance by addition in their drinking water on the 12th, 18th and 29th day of their life a strain of serogroup 078 Escherichia coli. The quails were randomly divided in 4 groups (A, B, C and D) of 30 birds each. The group A was subdivided in 2 of equal number subgroups, i.e. the A1 (negative control) and the A2 (positive control), while every one of the other groups in 2 of equal number replicates. The birds of groups A (controls) were fed a standard growth-fattening basal diet, while those of groups B, C and D were fed with the same basal diet supplemented with 125 ppm, 250 ppm and 500 ppm of acetylsalicylic acid, respectively. In these birds' drinking water of the subgroup A2 and the groups B, C and D, a 24 hours broth culture of the above strain of Escherichia coli was added at the prementioned days of their life (37X(10exp8) bacterial cells/3 L of drinking water for 24 hours). The quails raised on a litter floor under a temperature of 30 degree C for the first 12 days of their life, but for the following days on a battery under a temperature of 24 degree C during the night and 29 degree C during the day. The results taken indicated that the addition of acetyl salicylic acid in the diet of growth-fattening quails in the proportions of 125 ppm, 250 ppm and 500 ppm does not influence, positively or negatively, the growth, feed conversion ratio and mortality, even their drinking water on 12th, 18th and 29th day of their life was surcharged with E. coli.
