dc.description.abstractThe study was conducted to evaluate use of Esterified Butyrates on production performance, gut health and immunity of broilers. The trial was conducted on 360 ‘Cobb 430’ strain, straight-run broilers for a period of five weeks. The day-old chicks were randomly divided into four groups viz. A, B, C and D of 90 birds each, which were further sub-divided into six replicates of 15 birds each. Group A was the control, receiving corn soybean diet and Group B received diets supplemented with Lincomycin @ 250 g/T. The birds from Group D receiving diet with Esterified Butyrates @ 600 g/T, exhibited the numerically higher live weight, total gain in weight, lower feed consumption with better feed conversion ratio and European Production Efficiency Factor (EPEF) as compared to all treatment groups indicating superior growth and efficiency of production. Birds from Group D also recorded the lowest mortality rate, suggesting better overall health. The birds from Group C receiving diet with Esterified Butyrates @ 300 g/T, recorded the highest net profit per bird and per kg suggesting good economic returns. There was no significant difference in total viable count, total coliform count, intestinal villi length, crypt depth and their ratio by the birds from all treatment groups including the birds from control. The birds from group C recorded better HI antibody titer (@ 8 HAU) for NCD in the third week whereas birds from group D recorded better HI antibody titer (@ 8 HAU) for NCD in the fifth week. Thus, it is concluded that, the supplementation of Esterified Butyrates @ 600 g/T, in diet is useful in enhancing production performance, while supplementation of Esterified Butyrates @ 300 g/T, in diet is useful in recording better economic returns. Therefore, Esterified Butyrates could be a good alternative to antibiotic growth promoters in broilers.
