Wang P, Sun LH, Wang X, Wu Q, Liu A. Effective protective agents against the organ toxicity of T-2 toxin and corresponding detoxification mechanisms: A narrative review. ANIMAL NUTRITION (ZHONGGUO XU MU SHOU YI XUE HUI) 2024; 16:251-266. [PMID: 38362519 PMCID: PMC10867609 DOI: 10.1016/j.aninu.2023.12.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 08/28/2023] [Accepted: 12/01/2023] [Indexed: 02/17/2024]
Abstract
T-2 toxin is one of the most widespread and toxic fungal toxins in food and feed. It can cause gastrointestinal toxicity, hepatotoxicity, immunotoxicity, reproductive toxicity, neurotoxicity, and nephrotoxicity in humans and animals. T-2 toxin is physicochemically stable and does not readily degrade during food and feed processing. Therefore, suppressing T-2 toxin-induced organ toxicity through antidotes is an urgent issue. Protective agents against the organ toxicity of T-2 toxin have been recorded widely in the literature, but these protective agents and their molecular mechanisms of detoxification have not been comprehensively summarized. In this review, we provide an overview of the various protective agents to T-2 toxin and the molecular mechanisms underlying the detoxification effects. Targeting appropriate targets to antagonize T-2 toxin toxicity is also an important option. This review will provide essential guidance and strategies for the better application and development of T-2 toxin antidotes specific for organ toxicity in the future.

Animals (Basel) 2023; 13:ani13081386. [PMID: 37106949 PMCID: PMC10135100 DOI: 10.3390/ani13081386] [Citation(s) in RCA: 12] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 04/14/2023] [Accepted: 04/16/2023] [Indexed: 04/29/2023] Open
Abstract
Poultry meat is becoming one of the most important animal protein sources for human beings in terms of health benefits, cost, and production efficiency. Effective genetic selection and nutritional programs have dramatically increased meat yield and broiler production efficiency. However, modern practices in broiler production result in unfavorable meat quality and body composition due to a diverse range of challenging conditions, including bacterial and parasitic infection, heat stress, and the consumption of mycotoxin and oxidized oils. Numerous studies have demonstrated that appropriate nutritional interventions have improved the meat quality and body composition of broiler chickens. Modulating nutritional composition [e.g., energy and crude protein (CP) levels] and amino acids (AA) levels has altered the meat quality and body composition of broiler chickens. The supplementation of bioactive compounds, such as vitamins, probiotics, prebiotics, exogenous enzymes, plant polyphenol compounds, and organic acids, has improved meat quality and changed the body composition of broiler chickens.

Abstract
Growth retardation is a global public health problem that is highly prevalent especially in low-and middle-income countries, which is closely related to the consumption of grains contaminated with T-2 toxin, a risk for human and animal health. However, the possible targets that can relieve T-2 toxin-induced growth retardation still need to be explored. In the present study, T-2 toxin was used as an environmental exposure factor to induce growth retardation and further explore the regulatory role of lncRNA in growth retardation. The present study systematically characterised the expression profiles of lncRNAs and identified a lncRNA lncMST that is related to growth retardation in T-2 toxin-administered rats. Functionally, lncMST could alleviate cell cycle arrest and apoptosis in T-2 toxin-treated GH3 cells. Mechanistically, lncMST, serve as an inducible chaperone RNA, involved in the paradigm "Chemical-induced stress related growth retardation", through recruiting the EPRS/HSP90AB1 complex to increase HDAC6 expression, thus further alleviating T-2 toxin-induced growth retardation. These findings for the first time demonstrate that the probable therapeutic relationship between lncMST and growth retardation, providing an explanation and therapeutic targets for the pathogenesis of growth retardation.

Abstract
This review summarizes the updated knowledge on the toxicity of T-2 on poultry, followed by potential strategies for detoxification of T-2 in poultry diet. The toxic effects of T-2 on poultry include cytotoxicity, genotoxicity, metabolism modulation, immunotoxicity, hepatotoxicity, gastrointestinal toxicity, skeletal toxicity, nephrotoxicity, reproductive toxicity, neurotoxicity, etc. Cytotoxicity is the primary toxicity of T-2, characterized by inhibiting protein and nucleic acid synthesis, altering the cell cycle, inducing oxidative stress, apoptosis and necrosis, which lead to damages of immune organs, liver, digestive tract, bone, kidney, etc., resulting in pathological changes and impaired physiological functions of these organs. Glutathione redox system, superoxide dismutase, catalase and autophagy are protective mechanisms against oxidative stress and apoptosis, and can compensate the pathological changes and physiological functions impaired by T-2 to some degree. T-2 detoxifying agents for poultry feeds include adsorbing agents (e.g., aluminosilicate-based clays and microbial cell wall), biotransforming agents (e.g., Eubacterium sp. BBSH 797 strain), and indirect detoxifying agents (e.g., plant-derived antioxidants). These T-2 detoxifying agents could alleviate different pathological changes to different degrees, and multi-component T-2 detoxifying agents can likely provide more comprehensive protection against the toxicity of T-2.

Abstract
The contamination of food commodities with mycotoxins could be a serious health threat to humans and animals. Therefore, identification, quantification and reduction of mycotoxins in food commodities, particularly of aflatoxins (AFs) and ochratoxin A (OTA) in grain foods, is essentially required to guarantee safe food. This study determined the levels of AFs and OTA in 135 maize grains samples belonging to eight salient maize varieties cultivated in Pakistan, and evaluated the usefulness of radiations and adsorbents to reduce their levels. High performance liquid chromatography (HPLC)-based method was validated for the determination of AFs and OTA in maize grains. The results showed that 69 and 61% samples were positive for AFs and OTA, respectively and 54 and 22% of the respective samples had AFs and OTA above the permissible limits set by Pakistan Standards and Quality Control Authority. The concentration of AFs, AFB1and OTA in grains ranged from 14.5 to 92.4, 1.02 to 2.46 and 1.41 to 53.9 μg kg-1, respectively. Among the varieties, Pearl had the highest level of total AFs and OTA, whereas YH-5427 had the highest AFB1 level. The lowest concentration of AFs and OTA was found in Malaka and 30Y87, respectively. The use of 15 kGy gamma irradiation for 24 h, sunlight-drying for 20 h and UV irradiation for 12 h almost completely degraded the mycotoxins. The microwave heating for 120 s resulted in 9-33% degradation of mycotoxins. Moreover, the treatment of grains' extract with activated charcoal (5% w/w) removed > 96% of total AFs and AFB1, and up to 43% of OTA. The use of bentonite at the same rate removed OTA, total AFs and AFB1 by 93, 73 and 92%, respectively. Thus, it is concluded that contamination of maize grains with mycotoxins was fairly high in the collected maize grain samples in Pakistan, and treatment with radiations and adsorbents can effectively reduce mycotoxins contamination level in maize grains.

Abstract
Background. Feed-borne T-2 toxin may inhibit innate immune system function in birds.The aim. To evaluate the effect of T-2 toxin, artificially introduced with feed, on the expression level of a number of immunity-related genes in the tissues of the broiler digestive system.Materials and methods. The experiments were carried out in the vivarium of the FSC “VNITIP” RAS broilers of the Smena 8 cross from 33 to 47-day old. Experimental contamination of feed T-2 toxin was performed. The birds were divided into 4 groups of 5 animals each: I – control, receiving a diet without the introduction of T-2 toxin, II experimental – receiving a diet with the addition of T-2 toxin, III experimental – receiving a diet with the addition of T-2 toxin and the sorbent Zaslon2+, IV experimental – receiving a diet with the addition of T-2 toxin, the same sorbent Zaslon2+and Axtra Pro enzyme. The level of mRNA expression was analyzed by quantitative reverse transcription PCR.Results. The data obtained indicated the impact of T-2 toxin contamination of broiler feed on the modulation of the level of expression of genes associated with the functioning of the immune system in the cecum and pancreas. Exposure to T-2 toxin (group II) led to an increase in the expression of the pro-inflammatory gene IL-6 in the tissues of the caecum by 10.8 times and IL-8 in the pancreas by 3.89 times (p ≤ 0.05) compared with control group I. The effect of the sorbent, as well as the complex, including the sorbent and the enzyme, on the expression of broiler genes was positive. The sorbent without the enzyme showed greater efficiency than with the additional introduction of the enzyme.

Meta-analysis of the effects of mycotoxins and yeast cell wall extract supplementation on the performance, livability, and environmental sustainability of broiler production.

Abstract
The effect of mycotoxins (MT) on broiler performance without or with the inclusion of yeast cell wall extract (YCWE, Mycosorb, Alltech, Inc., KY) was evaluated in a random-effects meta-analysis. Data was extracted from 25 research experiments with a total of 10,307 broilers. Broilers fed MT had lower (P < 0.001) body weight gain (BWG, −217 g), reduced feed intake (FI, −264 g), increased feed conversion ratio (FCR, 0.12), and greater mortality by 2.01%. Inclusion of YCWE improved (P < 0.001) BWG (59 g) and FI (65 g), lowered FCR (−0.05), and reduced mortality by 1.74%. Additionally, change in European Production Efficiency Factor (EPEF) was assessed. Feeding MT lowered (P < 0.001) EPEF while YCWE increased (P < 0.001) EPEF. Finally, the carbon footprint of production was evaluated. Control fed birds produced an estimated 1.93 kg CO2-equivalent/kg liveweight (LW), while MT fed broilers produced 2.13 kg CO2-equivalent/kg LW and YCWE inclusion lowered this to 2.03 kg CO2-equivalent/kg LW which resulted in −25 tonnes less CO2-equivalent output per 100,000 birds with YCWE. In conclusion, mycotoxins can play a role in reducing broiler performance and farm production output, as well as increase the carbon footprint. Inclusion of YCWE in feed under a mycotoxin challenge can improve broiler performance and output, as well as lower carbon footprint, which could play a role in farm efficiency, profitability, and environmental sustainability.

Abstract
Mycotoxin contamination in pig feeds has a negative impact on growth performance,
the immune system, and major body organs. Arginine (Arg) plays an important role
in animals’ body biochemistry and physiology. This study aimed to
determine the effect of dietary Arg supplementation on mitigating the negative
effects of mycotoxins in growing pigs. A total of 72 growing pigs (Landrace
× Large white) with initial mean body weight (BW) = 55 ± 2.5 kg
were allotted to four treatment groups with three replicates per group of six
pigs per replicate in a completely randomized design. The treatments included a
non-toxin diet with 1.2% Arg (NT1.2) and mycotoxin-challenged treatments
supplemented with 1.2% Arg (TX1.2), 1.3% Arg (TX1.3), and 1.4% Arg (TX1.4).
Statistical analysis of data included the effects of dietary level of Arg. The
results indicated a significantly higher BW (p < 0.05),
average daily gain (p < 0.05), and gain-to-feed ratio
(p < 0.05) in the NT1.2 group than in the TX1.2,
TX1.3, and TX1.4 groups. The relative weight of the liver was higher
(p < 0.05) in the TX1.2 compared to that of the
NT1.2 group, although it was not different from that of TX1.3 and TX1.4. The
level of tumor necrosis factor-alpha was significantly up-regulated
(p < 0.05) in the liver tissue of the TX1.2 group
compared to that of the other treatments. Overall, dietary Arg supplementation
remedied liver injury and alleviated the compromised immune system caused by
mycotoxin toxicity.

Abstract
AbstractMycotoxins are secondary metabolites of different species of fungi. Aflatoxin B1 (AFB1), deoxynivalenol (DON), zearalenone (ZEN) and fumonisin B1 (FB1) are the main mycotoxins contaminating animal feedstuffs. These mycotoxins can primarily induce hepatotoxicity, immunotoxicity, neurotoxicity and nephrotoxicity, consequently cause adverse effects on the health and performance of animals. Therefore, physical, chemical, biological and nutritional regulation approaches have been developed as primary strategies for the decontamination and detoxification of these mycotoxins in the feed industry. Meanwhile, each of these techniques has its drawbacks, including inefficient, costly, or impractically applied on large scale. This review summarized the advantages and disadvantages of the different remediation strategies, as well as updates of the research progress of these strategies for AFB1, DON, ZEN and FB1 control in the feed industry.

Abstract
BACKGROUND Alternariol (AOH) and alternariol monomethyl ether (AME), produced by Alternaria spp., are the two mycotoxins with the highest outbreak rates in food systems. The purpose of this study was to investigate the removal of AOH and AME from aqueous solutions by inactivated yeast cells. The effects of strains, yeast powder amount, temperature, and pH were evaluated. The kinetics of AOH and AME adsorption on inactivated yeast cells was fitted with four models and a release assay was carried out. RESULTS All three tested yeasts could remove AOH and AME. GIM 2.119 was the most effective strain. The reduction rate of both AOH and AME could be as much as 100% with 40 g‧L-1 of yeast powder. For both mycotoxins, pH = 9 was the best environment for toxin removal. The pseudo-second-order kinetic model was the best model, with R2 ranging from 0.989 to 0.999. However, the R2 of the pseudo-first-order and Elovich models was also relatively high. Alternariol and AME could be partially eluted by methanol and acetonitrile. CONCLUSION The inactivated yeast cells could effectively remove AOH and AME. This was best fitted by the pseudo-second-order model. The release assay suggested that the adsorption of Alternaria mycotoxins was partially reversible. The results of this study provide a theoretical basis for the removal of Alternaria mycotoxins from food systems and are useful for the investigation of the mechanisms involved in mycotoxin adsorption by inactivated yeast cells. © 2020 Society of Chemical Industry.

Abstract
Aflatoxin contamination of diets results in disease and death in humans and animals. The objective of the present paper was to review the development of innovative enterosorption strategies for the detoxification of aflatoxins. NovaSil clay (NS) has been shown to decrease exposures to aflatoxins and prevent aflatoxicosis in a variety of animals when included in their diets. Results have shown that NS clay binds aflatoxins with high affinity and high capacity in the gastrointestinal tract, resulting in a notable reduction in the bioavailability of these toxins without interfering with the utilization of vitamins and other micronutrients. This strategy is already being utilized as a potential remedy for acute aflatoxicosis in animals, and as a sustainable intervention via diet. Animal and human studies have confirmed the apparent safety of NS and refined NS clay (with uniform particle size). Studies in Ghanaians at high risk of aflatoxicosis have indicated that NS (at a dose level of 0.25% w/w) is effective at decreasing biomarkers of aflatoxin exposure and does not interfere with levels of serum vitamins A and E, or iron or zinc. A new spinoff of this strategy is the development and use of broad-acting sorbents for the mitigation of environmental chemicals and microbes during natural disasters and emergencies. In summary, enterosorption strategies/therapies based on NS clay are promising for the management of aflatoxins and as sustainable public health interventions. The NS clay remedy is novel, inexpensive, and easily disseminated.

Abstract
The exploration of feed mycotoxin adsorbents to mitigate the adverse effects of mycotoxins on animals has received increasing attention over the last decade. The present study was conducted to assess the efficacy of nano-composite magnetic graphene oxide with chitosan (MGO-CTS) adsorbents against feed contaminated with ~20 ng/g (ppb) aflatoxin (AF). A total of three hundred 1-day-old chicks were randomly distributed into six dietary treatment groups, as follows: basal diet (broilers fed a diet with neither AF nor MGO-CTS added, T1), basal diet + 0.25% MGO-CTS (T2), basal diet + 0.50% MGO-CTS (T3), AF diet + 0.25% MGO-CTS (T4), AF diet + 0.50% MGO-CTS (T5), and AF diet (T6). The two inclusion levels (0.25 and 0.50%) of MGO-CTS significantly (p < 0.05) improved the growth performances and feed conversion ratios of the AF-treated chicks at 1⁻35 days of age, and the impact was more pronounced for 0.5% MGO-CTS. The AF intake markedly increased the relative weights of the liver and kidney, resulting in significant alterations in the serum biochemical parameters, such as albumins, alkaline phosphatase, and SGPT/alanine (ALT), at 35 days of age. However, the chickens fed 0.5% MGO-CTS with AF diets had apparent recovery or restoration of AF-induced organ lesions and aberrant serum profiles. A significant (p < 0.05) reduction in the total AFs was observed in the gastrointestinal tracts of the chickens fed 0.25% or 0.50% adsorbent in combination with AF feed (T4 and T5), with decreases of 28.9% and 53.5%, respectively, compared with that in the chickens fed an AF-contaminated diet (T6). The results of the study indicated that a higher concentration of MGO-CTS (0.50%) was effective in improving the overall performance of broiler chickens by preventing the adverse effects associated with aflatoxicosis.

Abstract
This study aimed to investigate the effect of lactic acid bacteria (LAB) and smectite on the growth performance, nutrient digestibility and blood parameters of broilers that were fed diets contaminated with aflatoxin B1 (AFB1 ). A total of 480 newly hatched male Arbor Acres broilers were randomly allocated into four groups with six replicates of 20 chicks each. The broilers were fed diets with the AFB1 (40 μg/kg) challenge or without (control) it and supplemented with smectite (3.0 g/kg) or LAB (4.0 × 1010 CFU/kg) based on the AFB1 diet. The trial lasted for 42 days. The results showed that during days 1-42 of AFB1 challenge, the feed intake (FI) and body weight gain (BWG) were depressed (p < .05). The inclusion of LAB and smectite increased (p < .05) the BWG by 71.58 and 41.89 g/bird, respectively, which reached the level of the control diet (p ≥ .05), but there were no differences (p ≥ .05) in performance between LAB and smectite. LAB and smectite also increased (p < .05) the apparent total tract digestibility of the crude protein. Regarding the blood parameters, AFB1 decreased (p < .05) the levels of red blood cell count, haematocrit, mean corpuscular volume, haemoglobin, albumin and total protein. In the meantime, the AFB1 increased (p < .05) leucocyte counts, urea nitrogen, cholesterol, total bilirubin, creatinine, glutamic-pyruvic transaminase, glutamic oxaloacetic transaminase and alkaline phosphatase. By contrast, LAB and smectite affected (p < .05) these parameters in the opposite direction. It can be concluded that after the AFB1 challenge, LAB and smectite have similar effects on the growth and health of the broilers, suggesting that LAB could be an alternative against AFB1 in commercial animal feeds.

Abstract
Contamination of animal feed with mycotoxins still occurs very often, despite great efforts in preventing it. Animal feeds are contaminated, at low levels, with several mycotoxins, particularly with those produced by Aspergillus and Fusarium genera (Aflatoxin B1, Ochratoxin A, Zearalenone, Deoxynivalenol and Fumonisina B1). In animal feed, to date, only Aflatoxin B1 is limited through EU regulation. Consequently, mycotoxins cause serious disorders and diseases in farm animals. In 2009, the European Union (386/2009/EC) approved the use of mycotoxin-detoxifying agents, as feed additives, to prevent mycotoxicoses in farm animals. The present review gives an overview of the problem of multi-mycotoxin contamination of feed, and aims to classify mycotoxin adsorbing agents (minerals, organic, and synthetic) for feed decontamination, focusing on adsorbents with the ability to bind to multiple mycotoxins, which should have a more effective application in farms but they are still little studied in scientific literature.

Abstract
In geese, overfeeding induces hepatic steatosis and makes the liver functions enhanced. Aluminosilicate absorbs toxins created by moulds in animal feeds and enhances nutrient absorption. In the present study, the effects of hydrated sodium calcium aluminosilicate (Improved HSCAS, Jumpstar) on the growth performance, fatty liver, serum parameters, and intestinal morphology of overfed Landes geese were evaluated. The study included two Control groups, a non-overfed Control (Control I) and an overfed Control (Control II), as well as a treatment group. The results showed that compared with the Control I group, liver weight, relative liver weight, abdominal fat weight, intestinal fat weight, villus height, total cholesterol, very low density lipoproteins, lipoprotein lipase, aspartate aminotransferase, IgM, and IgG in the HSCAS treatment group all significantly increased (P < 0.05) at Days 10 and 20. The villus height/crypt depth, triglycerides, cholinesterase, alanine aminotransferase, and serum IgA levels were higher than those in the Control I (P < 0.05) after 20 days of overfeeding. Compared with the Control II group, the relative abdominal fat weight, relative intestinal fat weight, and crypt depth in the HSCAS treatment group were significantly increased (P < 0.05) after 10 days of overfeeding, whereas villus height/crypt depth decreased (P < 0.05). Relative liver weight and IgA were higher in HACAS group after 20 days’ overfeeding (P < 0.05). HSCAS treatment also led to higher cholinesterase, very low density lipoproteins and decreased lipase, alanine aminotransferase (P > 0.05), and decreased aspartate aminotransferase levels than those in the Control II group (P < 0.05). In conclusion, HSCAS treatment had a beneficial effect on fatty liver production, intestinal development, and serum parameters in overfed Landes geese, which could enhance the health status of these geese.

Abstract
The aim of the study was to evaluate the effects of low to moderate oral exposure to the Fusarium toxin deoxynivalenol (DON; derived from culture material) on performance, water intake, and carcass parameters of broilers during early and late developmental phases. A total of 160 Ross 308 broilers were randomly allocated to four different feeding groups (n = 40/group) including 0 (control), 2.5, 5, and 10 mg DON/kg wheat-soybean meal-based feed. Three consecutive replicates of the experiment were performed. Half of the broilers were slaughtered in week 3 of the trial whereas the other half were slaughtered in week 5. Dry matter intake (DMI) and water intake (WI) were recorded on a daily basis and the body weight (BW) and BW gain (BWG) were determined weekly. The following carcass traits were recorded and calculated in absolute and relative data: dressed carcass weight, breast muscle weight, leg weight, and liver weight. Data showed that BW (P < 0.001), BWG (P = 0.005), and DMI (P < 0.001) were reduced by DON-feeding during the entire feeding period. The ratio of DMI to body weight gain (DMI/BWG) was not affected by the treatment. However, the ratio of water to DMI (WI/DMI) increased in DON-treated birds (P = 0.021). Contrast analysis showed that DON tendentially reduced slaughter weight (P = 0.082) and decreased leg yield (P = 0.037) in DON-fed chickens in week 5 of the experiment. Liver organ weight decreased in the 3-week-old DON-fed broilers compared to that in the control-fed birds (P = 0.037). In conclusion, the study suggests that DMI and BW were negatively affected under the experimental conditions at DON levels lower than the current guidance value in the European Union of 5 mg/kg feed. The study also indicates that broilers fed on low to moderate level DON-contaminated diets showed increased WI/DMI ratio which might have negative influence on wet litter syndrome.

Abstract
The use of alternative feed ingredients in farm animal's diets can be an interesting choice from several standpoints, including safety. In this respect, this study investigated the safety features of selected former food products (FFPs) intended for animal nutrition produced in the framework of the IZS PLV 06/14 RC project by an FFP processing plant. Six FFP samples, both mash and pelleted, were analysed for the enumeration of total viable count (TVC) (ISO 4833), Enterobacteriaceae (ISO 21528-1), Escherichia coli (ISO 16649-1), coagulase-positive Staphylococci (CPS) (ISO 6888), presumptive Bacillus cereus and its spores (ISO 7932), sulphite-reducing Clostridia (ISO 7937), yeasts and moulds (ISO 21527-1), and the presence in 25 g of Salmonella spp. (ISO 6579). On the same samples, the presence of undesired ingredients, which can be identified as remnants of packaging materials, was evaluated by two different methods: stereomicroscopy according to published methods; and stereomicroscopy coupled with a computer vision system (IRIS Visual Analyzer VA400). All FFPs analysed were safe from a microbiological point of view. TVC was limited and Salmonella was always absent. When remnants of packaging materials were considered, the contamination level was below 0.08% (w/w). Of note, packaging remnants were found mainly from the 1-mm sieve mesh fractions. Finally, the innovative computer vision system demonstrated the possibility of rapid detection for the presence of packaging remnants in FFPs when combined with a stereomicroscope. In conclusion, the FFPs analysed in the present study can be considered safe, even though some improvements in FFP processing in the feeding plant can be useful in further reducing their microbial loads and impurity.

Abstract
In the recent years, mycotoxins have undoubtedly gained a keen interest of the scientific community studying food safety. The main reason is their profound impact on both human and animal health. International surveys reveal a low percentage of feed samples being contaminated above permitted/guideline levels, developed to protect consumers of animal derived products. However, the deleterious impact of feed co-contaminated at low levels with numerous both known and regulated as well as novel mycotoxins on producing animals has been described. Associated effects on agro-economics world-wide include substantial pecuniary losses which are borne by the society as a whole. Even though good agronomic practice is thought to be the most effective way of preventing animal feed contamination, the EC have recognised the need to introduce an additional means of management of feed already contaminated with low-levels of mycotoxins to alleviate detrimental effects on agricultural production efficiency. This review discusses types of feed detoxifying agents described in scientific literature, their reported efficacy in both in vitro and in vivo systems, and comparison with available commercial formulations in the light of increasing knowledge regarding mycotoxin prevalence in the changing global environment.

Abstract
CONTEXT Aflatoxins as potent mycotoxins can influence vital parameters in chickens. Turmeric was used in decreasing toxic effect of mycotoxins on vital organs, traditionally. OBJECTIVE The study compared the protective effect of turmeric and Mycoad(TR) in broilers exposed to aflatoxin. MATERIALS AND METHODS Chickens (270) were divided into six groups. The chickens were fed a basal diet, turmeric extract (5 mg/kg diet), Mycoad(TR) (25 mg/kg diet), productive aflatoxin (3 mg/kg diet), aflatoxin plus turmeric extract (3 versus 5 mg/kg diet), and aflatoxin plus Mycoad(TR) (3 versus 25 mg/kg diet) in basal diet. At 28 d old, we determined plasma concentration of total protein, albumin, triglyceride, cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), calcium, potassium, phosphorous, uric acid, aspartate transferase (AST), and alanine aminotransferase (ALT). Furthermore, liver and kidney were sampled for pathological examination. RESULTS Chickens fed turmeric with aflatoxin had significant lower ALT, AST, and uric acid than chickens fed aflatoxin (11.4 ± 0.79, 228 ± 9, and 6 ± 0.4 versus 17.2 ± 1.7, 283 ± 5, and 7.7 ± 0.1) whereas, total protein, calcium, and HDL values in chickens fed aflatoxin plus turmeric increased significantly (2.66 ± 0.16, 8.4 ± 0.2, and 920 ± 4.1 versus 1.7 ± 0.17, 7 ± 0.2, and 690 ± 4.8). Pathological examination revealed severe congestion, degeneration, and necrosis in liver and kidney in chickens that received aflatoxin. DISCUSSION AND CONCLUSION The study showed that turmeric may provide protection against the toxic effects of aflatoxin on liver and kidney.

Dietary glutamate supplementation ameliorates mycotoxin-induced abnormalities in the intestinal structure and expression of amino acid transporters in young pigs. PLoS One 2014; 9:e112357. [PMID: 25405987 PMCID: PMC4236086 DOI: 10.1371/journal.pone.0112357] [Citation(s) in RCA: 43] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2014] [Accepted: 09/11/2014] [Indexed: 12/03/2022] Open
Abstract
The purpose of this study was to investigate the hypothesis that dietary supplementation with glutamic acid has beneficial effects on growth performance, antioxidant system, intestinal morphology, serum amino acid profile and the gene expression of intestinal amino acid transporters in growing swine fed mold-contaminated feed. Fifteen pigs (Landrace×Large White) with a mean body weight (BW) of 55 kg were randomly divided into control group (basal feed), mycotoxin group (contaminated feed) and glutamate group (2% glutamate+contaminated feed). Compared with control group, mold-contaminated feed decreased average daily gain (ADG) and increased feed conversion rate (FCR). Meanwhile, fed mold-contaminated feed impaired anti-oxidative system and intestinal morphology, as well as modified the serum amino acid profile in growing pigs. However, supplementation with glutamate exhibited potential positive effects on growth performance of pigs fed mold-contaminated feed, ameliorated the imbalance antioxidant system and abnormalities of intestinal structure caused by mycotoxins. In addition, dietary glutamate supplementation to some extent restored changed serum amino acid profile caused by mold-contaminated feed. In conclusion, glutamic acid may be act as a nutritional regulating factor to ameliorate the adverse effects induced by mycotoxins.

Abstract
One hundred sixty-two 21-d-old ducks were randomly allotted to 6 treatments with 3 levels of mycotoxin-contaminated corn (0, 50, and 100% M) and 2 levels of Calibrin-A (CA, a clay mycotoxin adsorbent, 0 and 0.1%) to evaluate the effects of increasing levels of mycotoxin-contaminated corn on nutrient utilization in ducks fed diets with or without CA. Endogenous losses were obtained from another 27 ducks. Excreta samples were collected to determine DM, OM, CP, amino acids, and gross energy. Gross energy was analyzed for computation of AME and TME. The apparent digestibility (AD) and true digestibility (TD) of the nutrients in all treatments with and without CA had common (P > 0.05) intercepts and slopes except Pro (P < 0.05). The AME, TME, AD, and TD of DM, OM, Phe, and Gly were linearly (P < 0.05) decreased as the concentration of contaminated corn in the diet increased. Ducks fed the 100% M diet supplemented with 0.1% CA increased AD and TD of Gly compared with the 100% M diet, and ducks fed 50 and 100% M diet supplemented with 0.1% CA increased AD and TD of Pro compared with 50% M and 100% M diet, respectively. In the present study, ducks fed mycotoxin-contaminated corn decreased nutrient digestibility in dose-dependent manner, and 0.1% CA supplementation improved AD and TD of Gly and Pro.

Dietary arginine supplementation enhances intestinal expression of SLC7A7 and SLC7A1 and ameliorates growth depression in mycotoxin-challenged pigs. Amino Acids 2013; 46:883-92.

Abstract
This study tested the hypothesis that dietary L-arginine supplementation confers beneficial effects on growing pigs fed a mold-contaminated diet. The measured variables included: (1) the average daily weight gain and feed:gain ratio; (2) activities of total superoxide dismutase, glutathione peroxidase, diamine oxidase, as well as amino acid and D-lactate concentrations in serum; (3) intestinal morphology; (4) expression of the genes for SLC7A7 (amino acid transporter light chain, y(+L) system, family 7, member 7), SLC7A1 (cationic amino acid transporter, y(+) system, family 7, member 1), SLC1A1 (neuronal/epithelial high affinity glutamate transporter, system XAG, member 1), SLC5A1 (sodium/glucose cotransporter, family 5, member 1) in the ileum and jejunum. Mycotoxins in feedstuffs resulted in an enlarged small intestine mass, oxidative injury in tissues, and reduced growth performance in pigs. Dietary arginine supplementation enhanced (P < 0.05) expression of jejunal SLC7A7 and ileal SLC7A1, in comparison with the control and mycotoxin groups. In addition, supplementing 1% L-arginine to the mycotoxin-contaminated feed had the following beneficial effects (P < 0.05): (1) alleviating the imbalance of the antioxidant system in the body; (2) ameliorating intestinal abnormalities; and (3) attenuating whole-body growth depression, compared with the mycotoxin group without arginine treatment. Collectively, these results indicate that dietary supplementation with L-arginine exerts a protective role in pigs fed mold-contaminated foods. The findings may have important nutritional implications for humans and other mammals.

Abstract
The effects of astaxanthin (ASTA) and esterified glucomannan (EMG) on hematological and serum parameters, and liver pathological changes in broilers fed on aflatoxin-B1 (AFB1) contaminated diet were investigated. Two hundred and forty 10-day-old broilers were randomly assigned to one of five dietary treatments including: (i) control diet; (ii) AFB1-contaminated diet; (iii) AFB1 + EGM diet; (iv) AFB1 + ASTA diet; and (v) AFB1 + EGM + ASTA diet. At 35 days old, blood and liver tissue samples were collected for analysis. Results indicated that total white blood cell (WBC) number, hemoglobin (Hgb) concentration, hematocrit (Hct) level, serum alanine amino transferase (AST) and γ-glutamyl transferase (GGT) activities, red blood cell (RBC) number, serum globulin (GLB) and urea nitrogen (BUN) concentrations (P < 0.05) were increased by feeding AFB1-contaminated diet. EMG and ASTA alleviated the alteration of RBC, WBC, Hgb and AST caused by AFB1-contaminated diet. Liver superoxide dismutase (SOD) activity was reduced, while myeloperoxidase (MPO) activity was increased by AFB1-contaminated diet (P < 0.05). Both EGM and ASTA restrained the increase of MPO activity (P < 0.05). Degeneration of the liver tissues was found in broilers fed AFB1-contaminated diet. It suggested that feeding 0.4 mg/kg AFB1-contaminated diet resulted in adverse effects on blood parameters and liver morphology. Dietary addition of EGM addition at 5 g/kg diet, ASTA at 10 mg/kg diet and especially their combination showed positive protection effects on alleviating the alteration of feeding AFB1. The results indicated that supplementation of 5 g EGM/kg diet, 10 mg ASTA/kg diet and their combination could partially or greatly alleviate the adverse effects caused by AFB1, with the EGM+ASTA group receiving the most effective treatment.

Effects of Bacillus subtilis ANSB060 on growth performance, meat quality and aflatoxin residues in broilers fed moldy peanut meal naturally contaminated with aflatoxins. Food Chem Toxicol 2013; 59:748-53. [PMID: 23872125 DOI: 10.1016/j.fct.2013.07.010] [Citation(s) in RCA: 48] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2013] [Revised: 07/01/2013] [Accepted: 07/03/2013] [Indexed: 11/25/2022]
Abstract
This study was conducted to investigate the toxic effects of aflatoxins and the efficacy of Bacillus subtilis ANSB060 for the amelioration of aflatoxicosis in broiler chickens. Six replicates of ten broilers each were assigned to one of seven dietary treatments, which were labeled C0 (basal diet); M0 (basal diet containing moldy peanut meal); C500 and C1000 (C0+500 or 1000 g/t aflatoxin biodegradation preparations, composed mainly of ANSB060); and M500, M1000 and M2000 (M0+500, 1000 or 2000 g/t aflatoxin biodegradation preparations). The concentrations of aflatoxin B₁, B₂, G₁ and G₂ in the moldy diets (M0, M500, M100 and M2000) fluctuated around 70.7±1.3, 11.0±1.5, 6.5±0.8 and 2.0±0.3 μg/kg, respectively. The results showed that the M0 diet caused a significant decrease in average daily weight gain and increased feed requirements, with a gain ratio increasing from d 8 to 42, deterioration in meat quality and aflatoxin residues in broilers' livers as compared with the C0 diet. The addition of ANSB060 to the aflatoxin-contaminated diets offset these negative effects, leading to the conclusion that ANSB060 has a protective effect on growth performance and meat quality while reducing the amount of aflatoxin residues in the livers of broilers fed naturally moldy peanut meal.
