Abstract
A feeding trial (42 days) was conducted to assess the influence of dietary sodium butyrate supplementation on performance, nutrient digestibility and economics of broiler chicken. Two hundred forty straight run commercial broiler chicks were distributed in four groups with 4 replicates of 15 chicks following completely randomized design. The groups consisted of a control fed the basal diet (SB0); other groups were fed basal diet supplemented with three levels each of sodium butyrate (SB) at 0.05 (SB0.05), 0.1 (SB01) and 0.15 (SB015) percent. The cumulative feed intake (g) was comparable (P>0.05) among the treatment groups up to 21 days age. However, the cumulative feed intake (g) from 22 to 42 days and for overall period was significantly reduced (P<0.05) in SB01 group than SB0 and SB0 05; whereas the intake in SB015 remained comparable. The cumulative body weights (g) were comparable (P>0.05) among treatment groups during 4–6 weeks and for overall period. The cumulative feed conversion ratio (FCR) of experimental groups remained comparable (P>0.05) on the first 21 days. However, during 46 weeks and overall FCR was significantly improved (P<0.05) in SB01 than SB0. Except for CP, the digestibility (%) for other nutrients remained comparable (P>0.05). A significant betterment (P<0.05) in CP digestibility (%) in SB supplemented groups was recorded than control. Economic returns were found to be better in group supplemented with SB01 than the respective levels of SB. Hence, it is concluded that dietary supplementation of sodium butyrate at 0.1% level positively modified growth performance, protein digestibility and economic returns in broiler chicken.
