The results showed no significant differences in mortality rates, liveweights, egg production, egg size, egg weight, shell weight, feed efficiency, and RBC picture between medicated and non-medicated groups. The number of eggs produced with thin, cracked and soft shells was higher in medicated groups than those recorded in the non-medicated control group. The total number of poor eggs produced however, was less than 1% of the total egg production. The results indicated that sulfamonomethoxine given continuously with the feed at the level of 0.0025% to 0.005% does not cause adverse effects on the general health and egg production performance of white leghorn layers
