“…This result is consistent with those reported by Marchioro et al (2013) that aflatoxin increased digestive enzymes of broilers, but did not improve their growth performance, indicating that absorption is affected by existence of mycotoxins in the diet. The improving role of 0.05% E-GM to neutralize the deleterious effects of mycotoxicosis on performance has been previously reported by Aravind et al (2003) and Modirsanei et al (2004). On the contrary, Liu et al (2011) failed to improve the chickens' performance by 0.05% E-GM supplementation.…”

The purpose of this study was to evaluate the effect of esterified glucomannan (E-GM) on performance, immunity, blood haematological and serum biochemical parameters in broilers exposed to diets naturally contaminated with mycotoxins. A total of 630 one-day-old male broiler chicks (Ross 308) were randomly assigned to 9 treatments and 5 replicates of 14 chicks based on factorial (3 × 3) arrangement in completely randomized design. The dietary treatments included 3 levels of substituting naturally contaminated corn (0%, 50% and 100%), three levels of E-GM (0%, 0.05% and 0.1%) and their interaction. Body weight gains (BWG), feed intake (FI) and feed conversion ratio (FCR) were evaluated from 7 to 49 days of age. Haematology, serum biochemical and enzyme activities were assessed. Antibody titre against Newcastle disease virus and infectious bursal disease was measured to evaluate the humoral immunity. In comparison to diets with no contamination, 50% and 100% naturally contaminated corn significantly decreased FI, BWG and FCR (P < .05). Supplementing 0.05% and 0.1% E-GM considerably improved the decreased BWG and FI (P < .05). However, only 0.1% binder ameliorated the negative impact of mycotoxins on FCR (P < .05). Replacement of contaminated corn remarkably diminished humoral immunity of chickens and increased liver enzyme activities which ameliorated by supplementing 0.05% and 0.1% of binder inclusion (P < .05). Results indicated that supplementing E-GM particularly at 0.1% level efficiently reversed the adverse effects of mycotoxins on broiler chickens. ARTICLE HISTORY

“…Zeolites (12,16), bentonites (7,11,26), and yeast/esterified glucomannan (1,4,6,15) were opted for because of their effect on reducing aflatoxin absorption from the gastrointestinal tract. Some studies have showed that the best method for decontamination is biological degradation by yeast and yeast components, which can remove aflatoxin under mild conditions, without using harmful chemicals or causing noticeable losses in nutritive value and palatableness of the feed (21,30).…”

The purpose of this study was to evaluate the efficacy of yeast glucomannan (YG) and sodium bentonite (SB) in reducing the toxicity in broilers fed a diet naturally contaminated with aflatoxin. Three hundred 7-day-old Ross 308 strain broilers were chosen and randomly assigned to 10 dietary treatments. Serum biochemical parameters and pathological changes in the liver were investigated at 42 d of age. Chickens fed a diet containing 250 ppb of aflatoxin displayed a decrease in uric acid, cholesterol, and triglycerides, and an increase in serum activities of AST and ALT when compared to control group. There were considerable gross and histopathological hepatic lesions (P < 0.05) in the form of small to moderate hydropic and/or fatty degeneration, bile duct hyperplasia, periportal fibrosis, cells infiltration, and congestion, in chickens fed the 250 ppb aflatoxincontaining diet. The addition of YG and SB to the aflatoxin-containing diet partially reduced the negative effects of aflatoxin. The 0.1% YG supplementation to the aflatoxin-contaminated diet significantly prevented the pathological effect of aflatoxin on serum biochemical parameters and liver, and was found to be more effective than other treatments.

“…In animal nutrition, clinoptilolites are used mainly to protect animals against mycotoxin intoxications (Skalicka and Makoova 1999;Skalicka et al 2000;Rizzi et al 2003;Modirsanei et al 2004;Desheng et al 2005), to eliminate heavy metals (Boranić 2000) and radionuclides (Poschl and Balas 1999;Vitorovic et al 2002;Branislava and Gordana 2004), as well as to prevent digestive tract diseases, to improve utilization of feed nutrients, and to improve hygienic and sanitary conditions in animal housing facilities (Meisinger et al 2001;Melenova et al 2003). They have a positive effect on the production performance in pigs (Veldman and Aar 1997;Papaioannou et al 2004) and in poultry (Amon et al 1997;Olver 1997).…”

The aim of this study was to assess the effects of two levels of clinoptilolite administered in feed (2% and 4%) on some selected performance indicators, metabolic utilization of basic nutrients and the health status of laying hens. The selected 24 Bovans Goldline hybrid laying hens were divided into three equal groups, two experimental groups (E1 and E2) and one control group (C). The laying hens were housed individually in cages with an automatic supply of drinking water, manual feeding, in a setting with controlled light and temperature regimens. Hens from individual groups were all fed a complete feed mix of the same composition and the only difference was in clinoptilolite supplementation: feed mixes for E1 and E2 groups contained 2% and 4% of clinoptilolite (commercial additive ZeoFeed) respectively, replacing the same amounts of wheat. The hens received feed mixes and drinking water ad libitum. During this 28-day experiment, feed consumption and the number and weight of eggs laid were monitored individually for each hen. At the end of the experiment, the balance test using the indicator method (Cr 2 O 3 ) was performed in all eight hens in each of the groups. The results of balance tests were then used to calculate the metabolic utilization of selected nutrients (nitrogen, fat, ash, nitrogen-free extracts, starch, gross energy, Ca, P). After the balance tests, blood samples for haematological and biochemical examinations were collected via puncture of the vena basilica. The addition of 2% clinoptilolite to feed mix resulted in a highly significant (P ≤ 0.01) increase in mean egg weight to 64.69 g, but the addition of 4% clinoptilolite in group E2 resulted in a highly significant (P ≤ 0.01) decrease in mean egg weight to 62.20 g compared to the control (63.73 g). Moreover, daily feed mix consumption in group E1 decreased to 114 g per one laying hen/day compared to the controls (118 g per one laying hen/day). In group E2 (4% clinoptilolite), daily consumption of feed mix increased compared with the controls to 124 g. The 2% clinoptilolite supplementation of E1 group feed slightly increased metabolic utilization of fat, nitrogen-free extracts, starch and gross energy compared to group C. Results of haematological test of the hens' blood showed significant changes in haemoglobin, whose values in groups C and E1 were significantly higher (P ≤ 0.05) than in group E2. Differences in the values of the biochemical indicators monitored (total protein, glucose, cholesterol, triacylglycerols, calcium, phosphorus, magnesium and the AST enzyme) between group C and experimental groups E1 and E2 were not significant and remained within the range of reference values. , nutrient balance, biochemical profile, mineral profile, haematological profile Feeds may be carriers of a number of contaminating exogenous substances that spread to food via food-producing animals and their products. For that reason, suitable approaches are being sought to prevent such substances from penetrating the animal organism and, subsequ...
