				Abstract 
 
              
              
              Aim: 
              
              An experiment was conducted to evaluate the effect of 
              supplementing different levels of salts of organic acid in the 
              laying hen’s diet on their production performance and egg quality 
              parameters during a period of 16-week. 
              
              
              Materials and Methods: 
              A 
              total of 140 white leghorn laying hens at 24 weeks of age were 
              randomly distributed to seven dietary treatment groups, i.e. T1 
              (control), T2 (0.5% sodium-butyrate), T3 (1.0% sodium-butyrate), 
              T4 (1.5% sodium-butyrate), T5 (0.5% calcium-propionate), T6 (1.0% 
              calcium-propionate) and T7 (1.5% calcium-propionate) consisting of 
              5 replications of 4 birds each in each treatment and housed in 
              individual cages from 24 to 40 weeks of age. Feed intake, percent 
              hen-day egg production, egg weight, egg mass production, feed 
              conversion ratio (FCR), and economics of supplementation of salts 
              of organic acids in layers’ ration were evaluated. 
              
              
              Results: 
              
              The dietary supplementation of salts of organic acids did not 
              significantly affect the feed intake (g/day/hen) and body weight 
              gain (g). Different levels of supplementation significantly 
              (p<0.05) improved production performance (percent hen-day egg 
              production and egg mass production) as compared to control group. 
              FCR in terms of feed intake (kg) per dozen eggs was lowest 
              (1.83±0.05) in T4 and feed intake (kg) per kg egg mass was lowest 
              (2.87±0.05) in T5 as comparison to control (T1) group. Salts of 
              organic acids supplementation resulted in significant (p<0.05) 
              improvement in FCR. Egg weight was significantly (p<0.05) 
              increased at 0.5% level of salts of organic acids in the diet. The 
              cumulative mean values of feed cost per dozen egg production were 
              Rs. 44.14, 42.40, 42.85, 43.26, 42.57, 43.29 and 43.56 in 
              treatment groups T1, T2, T3, T4, T5, T6 and T7, respectively, and 
              reduction in feed cost per kg egg mass production for Rs. 0.52 and 
              0.99 in groups T2 and T5, respectively, in comparison to T1 group. 
              
              
              Conclusions: 
              
              It can be concluded that supplementation of salts of organic acids 
              may improve persistency of lay, egg weight, and FCR. From 
              economical point of view, egg production was more profitable at 
              0.5% level of sodium butyrate and 0.5% level of calcium propionate 
              which reduced the feed cost per dozen eggs and per kg egg mass 
              production without affecting the egg quality.
