Efficacy of Toxin Binder in Reducing Induced Aflatoxin B1 and Ochratoxin A in Broiler Feed

Abstract

The object of present study was to investigate the ef cacy of toxin binder (Bentonite- montmorillonite + Sepiolite; TXB) at different levels of A atoxin B1 (AFB1) and Ochratoxin (OTA) in broilers. Eight iso-caloric/iso-nitrogenous experimental feeds i.e. A: standard feed/ control + zero toxin + zero TXB; B: Feed + zero toxin + TXB @ 1g/kg of feed; C: feed +100 ppb ofAFB1+TXB@1g/kg;D:feed+200ppb AFB1+TXB@1g/kg;E:feed+100ppbofOTA+ TXB @ 1g/kg; F: feed + 200 ppb of OTA + TXB @ 1g/kg; G: Feed + 100 ppb of AFB1+ 200 ppb of OTA + TXB @ 1g/kg; H: Feed + 200 ppb of AFB1+ 100 ppb of OTA + TXB @ 1g/kg, were prepared following NRC standards (1994) for commercial broiler. The each experimental feed was randomly assigned to 60 birds with 20 birds per replicate for 42 d. The data on feed intake (g), body weight gain (g), FCR, mortality, toxin binding ability, dressing %, keel and shank length, giblet weight (g), bursa, spleen and thymus weight (g), were recorded. Statistical analysis of data under Completely Randomized Design through One-way ANOVA revealed non-signi cant differences for feed intake, weight gain and FCR. Signi cantly higher dressing %, thymus and bursa weight was observed in birds fed 1g/kg TXB followed by 220ppb OTA + 1g/kg TXB and 200ppb AFB1 + 100 ppb OTA + 1g/kg TXB, respectively. It was concluded from the present study that TXB had signi cant effect in reducing AFB1 and OTA in broilers due to toxins binding and their excretion through excreta. The economic analysis showed 7% increase in pro t with addition of TXB.
