Evaluation of Endotoxin Binder as Growth Promoter in Broiler Production

Antibiotic growth promoter used in broilers not only mitigate the harmful pathogens colonising in gastrointestinal tract they also increase endotoxin release in gut lumen from killing Gramnegative bacteria. The current research was carried out to evaluate the effect of endotoxin binder (EB) alone and along with oxytetracycline antibiotic (AB) as growth promoter and to assess its techno-economics. Two hundred day-old Vencobb 400 broiler chicks were divided into five groups with four replicates of 10 chicks in each. Experimental groups fed with basal diet (BS) prepared as per BIS (IS 1374: 2007) recommendations. The birds in G1 fed with BD + 2.5 kg of EB/ton of feed, G2 fed with BD + 0.5 kg of AB /ton of feed, G3 with BD+ 2.0 kg of EB /ton, G4 with BD + 1.5 kg of EB /ton + 0.5 kg of AB /ton and G5 with BD + 1.0 kg of EB /ton + 0.5 kg of AB /ton. The present study results revealed G3 and G5 group birds gained significantly higher (p<0.01) body weight than G1 and G2 birds and cumulative feed intake in all group birds are similar at 42 nd day of its age. Cumulative feed conversion ratio calculated at 42 nd day, G3 was better (P<0.05) than G2 and G4, whereas G1 and G5 was similar to that of G3. The profit per kg live weight in G3 calculated was 1.22 times higher than G5 and 3.37 times higher than G2 group birds. The findings revealed better growth performance and better profit in G3 and G5 groups. It concluded that supplementation of endotoxin binder at 2 kg per ton of feed could be considered as alternative to antibiotic growth promoter for broilers.
