“…The anti-mycotoxin additives (bentonite, kaolin, and activated charcoal) added to AFB1-contaminated feed had a positive effect in reducing the negative effects of AFB1 on the relative weights of the organs, as they act as substances that absorb toxins by intestinal villi. This indicates that the additives played a positive role in preserving liver cells from damage due to their content of binding substances [19,20]. These results are consistent with a study conducted by Lemos et al [21], which found that adding kaolin to chicken feed increased the intestinal villi (the duodenum) in broiler chickens, reducing the moisture content of the feces and thus improving the intestinal health of broiler chickens.…”

“…In a study by Ghazalah et al [9], the addition of bentonite to broiler feed enhanced growth and reduced the negative effects of AFB1, showing the highest percentage increase in body weight compared to other treatments during the 29-30 day period. In another study, the addition of kaolin clay to feed at a ratio of (10,20,30) grams per kilogram of feed showed a significant improvement in feed intake and consequently improved growth [10]. A study conducted by Hu et al [11] found that adding montmorillonite clay to chicken feed positively increased weight.…”

The research was conducted to determine the effect of four types of clay minerals (Iraqi bentonite, English bentonite, Turkish bentonite, and Iraqi kaolin) and activated charcoal on reducing the negative effects of aflatoxin B1, which contaminates poultry feed at a concentration of 350 ppb. The results showed that the average bird weight reached 1134.5 grams in the aflatoxin treatment alone, with a significant difference compared to the control treatment (1690 grams). Adding English bentonite to the contaminated feed was efficient in reducing the impact of aflatoxin, as the bird weight did not differ significantly from the control treatment and reached 1686.9 grams, followed by Turkish bentonite, with an average bird weight of 1618.8 grams, and then Iraqi bentonite with an average weight of 1533.2 grams. The results also indicated that the relative weights of the liver, spleen, and pancreas increased in birds treated with aflatoxin alone. However, the addition of different clay minerals and activated charcoal led to a decrease in the relative weights of the internal organs. The relative weight of the heart and Proventriculus was not affected by the addition of aflatoxin to the feed. Blood analysis results showed a significant decrease in protein and albumin concentrations in the blood of birds treated with aflatoxin alone compared to the control treatment. Additionally, the different additions of clay minerals and activated charcoal had a positive effect on protein concentrations in the blood. Aflatoxin also caused a decrease in blood hemoglobin and red blood cell counts, an increase in white blood cell counts, and an increase in the Neutrophil/Lymphocyte index in birds treated with aflatoxin. However, blood viscosity did not change between the aflatoxin treatment and the other treatments.

“…In agreement, [23] , found no significant effect on feed intake, weight gain and feed conversion rate. Researchers who used higher levels of AFB1 (500 ppb and 170 ppb) in poultry diets still observed no decrease on the weight and feed intake [11,15] . The insignificant AFB1 effect on feed intake could be explained by the fact that aflatoxins normally reduce energy availability which results to birds consuming more feed to meet their energy requirements [23] .…”

This experiment evaluated the effects of a commercial binder ((Novasil®) and two natural products with the potential to bind Aflatoxin B1 (AFB1) on the growth performance of broilers. There were eight dietary treatments; treatment 1 (control), treatment 2 (control + AFB1), treatment 3 (control + (Novasil®)), treatment 4 (control + (Novasil®) +AFB1), treatment 5 (control + RHA), treatment 6 (control + RHA+ AFB1), treatment 7 (control + Banana peels) and treatment 8 (control + Banana peels + AFB1). The two natural binders were banana peels and rice husk ash (RHA). Four treatments (1, 3, 5 and 7) were formulated without aflatoxins while the other four (2, 4, 6 and 8) contained AFB1. All dietary treatments were formulated to meet the National Research Council (NRC, 1994) requirements for broiler grower and finisher feeds. The AFB1 concentration in the feeds was 100 ppb. One hundred and forty four unsexed day-old Arbo Acre day-old broiler chicks were randomly assigned to the eight treatments with three replicates each consisting of six chickens. The experimental period was forty two days. During the first 21 days, broilers were fed a grower feed and from 22-42 days, a finisher feed. The experimental design was a CRD with a 2 by 4 factorial arrangement. Feed intake, feed efficiency and chicks' weight were calculated on weekly basis for each bird. Data were analyzed using the general linear model (GLM) procedure of Statistical Analysis System software (SAS, 2009). The results showed that diets containing AFB1 did not significantly affect all the performance parameters. Feed efficiency of diet with rice husk ash was significantly (p<0.05) higher than the commercial binder ((Novasil®) ((Novasil®)®)) and banana peels during the finisher phase. The overall feed efficiency for the whole period (0-42 days) however, showed that RHA and banana peels had feed efficiency that was significantly higher (p<0.05) than the commercial binder. In conclusion, the natural binders had a significant improvement on feed efficiency compared to the commercial binder implying that they are superior in binding capacity to the commercial binder.

“…A slurry was prepared by adding 10 ml PBS (pH 7.2) and then autoclaved. To 10 ml of the feed slurry, the aflatoxin working solution was added to obtain a concentration of about 40 µg/L [49], that is, 400 µL of 1 µg/ml aflatoxin working solution. To ensure proper distribution, small amounts of the feed slurry were continuously mixed with the Aflatoxin working solution and homogenised.…”

Background: Contamination of animal feeds with aflatoxigenic fungi is a challenge to livestock farmers worldwide. Aflatoxins are very toxic fungal metabolites that are associated with carcinogenic, mutagenic, teratogenic, and estrogenic effects. The toxins affect animal productivity and may lead to deaths, causing enormous economic losses. Aflatoxin decontamination is a challenge to the feed industry, despite the several approaches available. This study investigated the efficacy of two microbial isolates, Bacillus spp (B285) and Yeast strain (Y833), in reducing Aflatoxin concentration in poultry feeds in comparison with a commonly used commercial chemical binder, Bentonite. The influence of the poultry feed matrix, pH, and temperature on the aflatoxin reducing activity by the two microorganisms was also explored. Results: The in vitro studies showed that the two microorganisms and the chemical binder reduced aflatoxins by over 74% of the original concentration. The chemical binder registered the highest reduction at 93.4%; followed by Y833 (83.6%), then the combination of Y833 and B285 (77.9%); and lastly B285 (74.9%). There was no significant (p>0.05) influence of temperature on the toxin reducing capacity of all the agents tested. The pHs 4.5 and 6.5 did not have a significant effect on the performance of both chemical binder and biological agents, however, the former performed better at pH 6.5 with 95% aflatoxin reduction compared to the microorganisms. The aflatoxin reducing activity was lower in presence of feeds compared to that in Phosphate Buffered Saline except for Y833 where no difference was observed. Conclusions: Although the feed components affected the aflatoxin reducing capacity of the test materials, the chemical binder was more effective than the microbial agents. Yeast strain was more effective than the bacterial strain in reducing the aflatoxin levels, however, both are promising strategies for countering the aflatoxin challenges in animal feeds. In response to the advocacy for use of biological control agents, there is need for more investigations to establish the safety of the microorganisms, the mechanism of decontamination and safety of the products; the optimum concentrations that can reduce aflatoxins in feeds to permissible levels and the effect of the toxin contamination levels on microbial efficiency.
