The addition of E-GM, SB, and FH to the aflatoxin-containing diet significantly ameliorated the adverse effects of aflatoxin on IBD and IB antibody titers, but FH supplementation to the contaminated diet with aflatoxin proved to be much more effective in the amelioration of the adverse effect of aflatoxin on humoral immunity against IB.

Özet

A study was conducted on the impact of aflatoxin (AF) and mycotoxin binders on immunization against Infectious Bursal Disease (IBD) and Infectious Bronchitis (IB) in chickens. Broiler chicks (7-day-old) were randomly assigned to 9 dietary treatments with 4 replicates of 12 chicks each. Treatments were 1) control; 2) diet containing corn naturally contaminated with AF (NCD); 3) NCD + 0.2% Farmagülatör DRYTM humate (FH); 4) NCD + 0.4% FH; 5) NCD + 0.6% FH; 6) NCD + 0.8% FH; 7) NCD + 1% FH; 8) NCD + 0.5% sodium bentonite (SB); and 9) NCD + 0.1% esterified glucomannan (E-GM). Data were evaluated with ANOVA for a complete randomized design, using the general linear models procedure of SAS software. Compared to control diet; the antibody titers of IB and IBD were significantly lower in the 254 ppb aflatoxin fed chicks from 28 to 35 days of age. The addition of E-GM, SB, and FH to the aflatoxin-containing diet significantly ameliorated the adverse effects of aflatoxin on IBD and IB antibody titers, but FH supplementation to the contaminated diet with aflatoxin proved to be much more effective in the amelioration of the adverse effect of aflatoxin on humoral immunity against IB.

Abstract

A study was conducted on the impact of aflatoxin (AF) and mycotoxin binders on immunization against Infectious Bursal Disease (IBD) and Infectious Bronchitis (IB) in chickens. Broiler chicks (7-day-old) were randomly assigned to 9 dietary treatments with 4 replicates of 12 chicks each. Treatments were 1) control; 2) diet containing corn naturally contaminated with AF (NCD); 3) NCD + 0.2% Farmagülatör DRYTM humate (FH); 4) NCD + 0.4% FH; 5) NCD + 0.6% FH; 6) NCD + 0.8% FH; 7) NCD + 1% FH; 8) NCD + 0.5% sodium bentonite (SB); and 9) NCD + 0.1% esterified glucomannan (E-GM). Data were evaluated with ANOVA for a complete randomized design, using the general linear models procedure of SAS software. Compared to control diet; the antibody titers of IB and IBD were significantly lower in the 254 ppb aflatoxin fed chicks from 28 to 35 days of age. The addition of E-GM, SB, and FH to the aflatoxin-containing diet significantly ameliorated the adverse effects of aflatoxin on IBD and IB antibody titers, but FH supplementation to the contaminated diet with aflatoxin proved to be much more effective in the amelioration of the adverse effect of aflatoxin on humoral immunity against IB.

Effect on one-day-old layer chicks simultaneously vaccinated against Newcastle disease, infectious bronchitis and infectious bursal disease. Avian Pathol., 1998; 27: 290—295. reported that using Na-bentonite up to 0.6% in the diet is effective in reducing aşatoxicosis in chickens (31). In the present study the addition of Na-bentonite was effective in ameliorating the negative effect of AF on antibody production. The ameliorative effect of dietary Na-bentonite on the reduced antibody titers caused by AF could be attributed to the role of Na bentonite as a sequestering agent of AF in the gastrointestinal tract. These results clearly demonstrated that the 254 ppb AF-treatment signiŞcantly affected the humoral immunity against IB and IBD, and the simultaneous addition of humic acid to the AF-containing diet provided signiŞcant reduction on the immunotoxic effects of AF. These improvements should contribute to a solution of the AF problem in broiler chickens, when used with mycotoxin management practices.
