“…Neem oil at 0.5% is also reported to have moderate antifungal activity (Gowda et al 2003). Among the chemical compounds, complete inhibition of mould growth and biosynthesis of aflatoxin is reported at an inclusion of 0.5% of propionic acid was reported by Ghosh et al (1996). El-Far et al (1992) reported complete inhibition of A. flavus growth and aflatoxin production at 0.64% inclusion levels of sodium propionate.…”

A feeding trail of 60 days was conducted for delineating the effect of dietary aflatoxin (AFB1) with or without supplementation of a mixture of mould inhibitor (0.25% clove oil + 0.32% sodium propionate) on haematology, respiratory burst activity and histology of Labeo rohita fingerlings. Three hundred and sixty fishes (avg. wt. 1.48-1.54 g) were randomly distributed into eight treatment groups. Eight experimental diets with four different levels of aflatoxin (0, 10, 20 and 40 ppb) with or without mould inhibitor were prepared. Haematological parameters like total serum protein, albumin, globulin and A:G ratio were significantly (P < 0.05) reduced with increasing levels of aflatoxin in the diet. However, supplementation of mould inhibitor showed enhanced values when compared to non-supplemented counter parts suggesting ameliorating effects of mould inhibitor on aflatoxin. Total leucocyte count was higher in aflatoxin-treated groups. Histological observations were complementary to haematological parameters. Respiratory burst activity was significantly (P < 0.05) decreased in higher aflatoxin-treated groups but not affected significantly (P > 0.05) due to inclusion of inhibitor alone and/or interaction of aflatoxin level and inhibitor in the diet. From this study, it was concluded that up to 20 ppb aflatoxin level in the diet the haemato-immunological parameters are protected.

“…At each of the three given moisture levels of 10, 15 and 20%, three groups (200 g each) of pelleted‐layer duck feeds mixed with a suitable quantity of ECE was exposed to ordinary air for 3 days to mimic the initiation of the natural molding process in the southern part of China. These samples were separately kept in polyethylene bags to maintain the moisture of the experimented feed with the temperature ranging from 18 to 33°C (Ghosh et al. 1996).…”

Aims:The cultures of an endophytic fungus Calcarisporium sp. were screened for inhibitors on the growth of feedassociated moulds and on the aflatoxin biosynthesis to find a safe and effective feed preservative. Methods and Results: Eight test fungi were isolated from the spoiled poultry feed. The endophytic fungus Calcarisporium sp. was separated from the Chinese coastal grass Cynodon dactylon. The antifungal action concerning the endophytic culture extract (ECE) was performed with propionic acid (PPA) as the corresponding reference. The ECE had a similar antifungal efficacy to PPA in a concentration-dependent manner. The susceptibility order of the ECE to the test fungi was found to be Fusarium sp. > Aspergillus spp. > Penicillium spp. Furthermore, the application of the ECE in pelleted-layer duck feed as a preservative was carried out at a humidity of 10, 15 and 20%. It has been discerned that mould growth and aflatoxin biosynthesis could be co-inhibited almost completely by ECE at concentrations higher than 1AE0% (w/w). The LD 50 of the ECE on mice was shown to be higher than 28 g kg )1 . Conclusions: The ECE can be selected as an inhibitor to preserve poultry feed on inhibiting the growth of mould and aflatoxin biosynthesis during feed storage. Significance and Impact of the Study: The ECE may be an effective and biosafe antifungal ingredient for poultry feed and holds a potential market prospect in feed industry.

“…However, since prevention is not always possible, decontaminating and/or detoxifying methods have been gaining attention as an alternative to reducing AFB1 contamination of feed and grains. Methods of detoxification can be physical, chemical, or biological treatments of contaminated feed or grains, and they can be as simple as the physical separation through screening, classification, and selection of damaged grains or as complex as gamma irradiation or chemical methods using ammonia, ozone, hydrogen peroxide, or some acids and alkalis [9][10][11][12][13][14]. Nevertheless, many of these methods to detoxify aflatoxin-contaminated feed are not currently available because they cannot be applied on a large scale and in a cost-effective manner or because many of them are impractical, ineffective, or potentially unsafe.…”

Mycotoxins - Impact and Management Strategies

View full text Add to dashboard Cite

An important approach to prevent aflatoxicosis in poultry is the addition of non-nutritional adsorbents in the diet to bind aflatoxin B1 (AFB1) in the gastrointestinal tract. These adsorbents are large molecular weight compounds that are able to bind the mycotoxin, forming a stable complex adsorbent-mycotoxin, which can pass through the gastrointestinal tract. In this chapter, we evaluate the use of polymers and probiotics to reduce AFB1 toxic effects in poultry. Our results on the efficacy of polymers and probiotics in sequestering mycotoxins are highly promising, although this field is still in its infancy and further research is needed. Furthermore, in vivo studies are needed to confirm the effectiveness of these materials against AFB1 toxic effects, since results in the past have indicated that there is great variability in the efficacy of adsorbing materials in vivo, even though the compounds may show potential adsorption capacity of the mycotoxin in vitro.
