Abstract
Simple Summary Phytate is the primary storage form of phosphorus in grain-based feedstuffs, which can reduce the utilization of the phosphorus, calcium, and other minerals. Additionally, non-starch polysaccha-rides can increase digesta viscosity and thus decrease the nutrient digestion and utilization. The current study has evaluated the effects of a next-generation multicarbohydrase and phytase com-plex on the growth performance, apparent total tract digestibility of nutrients, carcass traits, and meat quality in growing-finishing pigs fed a corn-wheat-soybean meal-based diet. The results showed that dietary supplementation of the multicarbohydrase and phytase complex improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs fed a corn-soybean meal-wheat-based diet. These findings indi-cate that the multicarbohydrase and phytase complex could be used as a promising enzymes product to mitigate the negative effects of phytate and non-starch polysaccharides. Abstract The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

Abstract
The objective of this study was to use isobaric tags for relative and absolute quantitation (iTRAQ) proteomic technology to systematically analyze the hepatotoxic mechanism of aflatoxin B1 (AFB1) and its prevention by Se in broilers. Four groups of day-old broilers were allocated into a 2 × 2 factorial design trial that fed a Se-deficient based diet (BD) or the BD + 1.0 mg AFB1/kg, 0.3 mg Se/kg, or 1.0 mg AFB1/kg plus 0.3 mg Se/kg for 3 wk. Dietary AFB1 increased serum ALT and decreased total protein and albumin concentrations, and induced hepatic histopathological lesions in Se adequate groups. Notably, Se deficiency exacerbated these AFB1-induced changes. Furthermore, Se deficiency reduced hepatic glutathione peroxidase but increased thioredoxin reductase and glutathione S-transferase activities and 8-hydroxydeoxyguanosine concentration in AFB1 administrated groups. Moreover, AFB1 dysregulated 261 co-differentially expressed proteins (DEPs) in both Se adequate and deficiency diets, and Se deficiency dysregulated 64 DEPs in AFB1 administrated diets. These DEPs are mainly related to phase I and II metabolizing enzymes, heat shock proteins, DNA repair, fatty acid metabolism and apoptosis. The in vitro study has verified that aldo-keto reductase family1, member10 plays an important role in AFB1-induced hepatotoxicity and Se-mediated detoxification of AFB1 in a chicken leghorn male hepatoma cells. Conclusively, this study has analyzed the hepatic proteome response to dietary AFB1 and Se, and thus shed new light on the mechanisms of hepatotoxicity of AFB1 and its detoxification by Se in broilers.

Abstract
Yeast culture (YC) positively affects the performance of laying hens. The purpose of the present study was to explore the underlying mechanism for the YC-mediated performance improvement. Sixty 67-week-old Hy-Line Brown laying hens were randomly allocated into 2 experimental groups with 5 replicates of 6 birds each. One group was fed a control diet, whereas the other received the control diet supplemented with YC at 3.0 g/kg; treatment lasted for 8 wk. The results showed that dietary YC supplementation increased (P < 0.05) the total egg weight (11.2–13.6%) and egg-laying rate (13.0–13.5%) but decreased (P < 0.05) the feed/egg ratio by 9.3 to 11.0% during weeks 5 to 6 and 7 to 8 compared with the control. However, egg quality, including eggshell strength, eggshell thickness, egg weight, albumen height, egg yolk color, and Haugh unit, was not affected (P > 0.05) by YC supplementation. Furthermore, dietary YC supplementation increased (P < 0.05) chymotrypsin and ɑ-amylase activities by 54.8 to 62.5% in the duodenal chyme and reduced (P < 0.05) plasma endotoxin by 44.1%. YC dietary supplementation also upregulated (P < 0.05) the mRNA levels of intestinal barrier–related genes (occludin and claudin 1) and antimicrobial peptides genes (β-defensin 1 and 7 and cathelicidin 1 and 3) in the duodenum or jejunum compared with the control. In conclusion, dietary YC supplementation improved the performance of aged laying hens, potentially through the upregulation of intestinal digestive enzyme activities and intestinal health-related gene expression.

Increased Consumption of Sulfur Amino Acids by Both Sows and Piglets Enhances the Ability of the Progeny to Adverse Effects Induced by Lipopolysaccharide. Animals (Basel) 2019; 9:ani9121048.

Abstract
Simple Summary Our results suggest that maternal consumption of total sulfur amino acids exceeding the NRC 2012 recommendations by 25% during late gestation and lactation benefits sow productivity and piglet neonatal performance. Moreover, increased consumption of sulfur amino acids by both sows and post-weaned piglets improved their ability to counteract the adverse effects by lipopolysaccharide (LPS) exposure. In addition, OH-Met showed a better response than DL-Met in both neonatal and weaned piglets. Taken together, our findings indicate that it might be necessary to update the recommendations for sulfur amino acids for gestating and lactating sows. Attention should also be given to sulfur amino acids supply during an inflammatory challenge as often encountered by piglets early in life. Abstract This study determined the effects of increased consumption of sulfur amino acids (SAA), as either DL-Met or Hydroxy-Met (OH-Met), by sows and piglets on their performance and the ability of the progeny to resist a lipopolysaccharide (LPS) challenge. Thirty primiparous sows were fed a diet adequate in SAA (CON) or CON + 25% SAA, either as DL-Met or OH-Met from gestation day 85 to postnatal day 21. At 35 d old, 20 male piglets from each treatment were selected and divided into 2 groups (n = 10/treatment) for a 3 × 2 factorial design [diets (CON, DL-Met or OH-Met) and challenge (saline or LPS)]. OH-Met and/or DL-Met supplementation increased (p ≤ 0.05) piglets’ body weight gain during day 0–7 and day 7–14. Sow’s milk quality was improved in the supplemented treatments compared to the CON. The LPS challenge decreased (p ≤ 0.05) piglets’ performance from 35 to 63 d and increased (p ≤ 0.05) the levels of aspartate aminotransferase, total bilirubin, IL-1β, IL-6, TNF-a, and malondialdehyde. Plasma albumin, total protein, total antioxidant capacity and glutathione peroxidase decreased post-challenge. The results were better with OH-Met than DL-Met. The increase of Met consumption, particularly as OH-Met increased piglets’ growth performance during the lactation phase and the challenging period.

Abstract
This study was conducted to determine the effect of T-2 toxin on the transcriptome of the glandular stomach in chicks using RNA-sequencing (RNA-Seq). Four groups of 1-day-old Cobb male broilers (n = 4 cages/group, 6 chicks/cage) were fed a corn-soybean-based diet (control) and control supplemented with T-2 toxin at 1.0, 3.0, and 6.0 mg/kg, respectively, for 2 weeks. The histological results showed that dietary supplementation of T-2 toxin at 3.0 and 6.0 mg/kg induced glandular gastric injury including serious inflammation, increased inflammatory cells, mucosal edema, and necrosis and desquamation of the epithelial cells in the glandular stomach of chicks. RNA-Seq analysis revealed that there were 671, 1393, and 1394 genes displayed ≥2 (P < 0.05) differential expression in the dietary supplemental T-2 toxin at 1.0, 3.0, and 6.0 mg/kg, respectively, compared with the control group. Notably, 204 differently expressed genes had shared similar changes among these three doses of T-2 toxin. GO and KEGG pathway analysis results showed that many genes involved in oxidation-reduction process, inflammation, wound healing/bleeding, and apoptosis/carcinogenesis were affected by T-2 toxin exposure. In conclusion, this study systematically elucidated toxic mechanisms of T-2 toxin on the glandular stomach, which might provide novel ideas to prevent adverse effects of T-2 toxin in chicks.

Abstract
BACKGROUND Selenium (Se) plays a protective role in aflatoxin B1 (AFB1)-induced splenic immunotoxicity in chicks. OBJECTIVE This study was designed to reveal the underlying mechanism of Se-mediated protection against AFB1-induced splenic injury in broilers. METHODS Four groups of 1-d-old Cobb male broilers (n = 5 cages/diet, 6 chicks/cage) were arranged in a 3-wk 2 × 2 factorial design trial whereby they were fed an Se-deficient, corn- and soy-based diet [base diet (BD), 36 μg Se/kg], BD plus 1.0 mg AFB1/kg, BD plus 0.3 mg Se/kg, or BD plus 1.0 mg AFB1/kg and 0.3 mg Se/kg (as 2-hydroxy-4-methylselenobutanoic acid). Serum and spleen were collected at week 3 to assay for cytokines, histology, redox status, selected inflammation- and apoptosis-related genes and proteins, and the selenogenome. RESULTS Dietary AFB1 induced growth retardation and spleen injury, decreasing (P < 0.05) body weight gain, feed intake, feed conversion efficiency, and serum interleukin-1β by 17.8-98.1% and increasing (P < 0.05) the spleen index and serum interleukin-6 by 37.6-113%. It also reduced the splenic lymphocyte number, the white pulp region, and histiocyte proliferation in Se-adequate groups. However, Se deficiency aggravated (P < 0.05) these AFB1-induced alterations by 16.2-103%. Moreover, Se deficiency decreased (P < 0.05) splenic glutathione peroxidase (GPX) activity and glutathione-S transferase and glutathione concentrations by 35.6-89.4% in AFB1-exposed groups. Furthermore, Se deficiency upregulated (P < 0.05) the apoptotic (Caspase 3 and Caspase 9) and antimicrobial (β defensin 1 and 2) genes, but downregulated (P < 0.05) antiapoptotic (B-cell lymphoma 2) and inflammatory (E3 ubiquitin-protein ligase CBL-B) genes at the mRNA and/or protein level in AFB1 supplementation groups. Additionally, Se deficiency downregulated (P < 0.05) GPX3, thioredoxin reductase 1 (TXNRD 1), GPX4, and selenoprotein (SELENO) S, and upregulated (P < 0.05) SELENOT and SELENOU in spleen in AFB1 administered groups. CONCLUSIONS Dietary Se deficiency exacerbated AFB1-induced spleen injury in chicks, partially through the regulation of oxidative stress, inflammatory and apoptotic signaling, and 6 selenoproteins.

Abstract
Background Zearalenone (ZEN) can cause serious defects in development and reproduction in humans and animals. Silymarin shows antioxidant and estrogenic effects. Objective This study was conducted to determine if silymarin can antagonize ZEN-induced hepatic and reproductive toxicities. Methods Thirty-five 21-d-old female Sprague-Dawley rats (n = 7/diet) were fed a control diet (Ctrl) or Ctrl plus 20 mg ZEN/kg or Ctrl plus 20 mg ZEN/kg with 100, 200, or 500 mg silymarin/kg for 6 wk. Serum, livers, ovaries, and uterus were collected at week 6 for biochemistry, hormone, and redox status and selected gene and protein assays. Results The consumption of ZEN decreased (P < 0.05) the final body weight by 17.9%, induced liver injury, increased (P < 0.05) aspartate aminotransferase and alkaline phosphatase activities, and decreased (P < 0.05) total protein and albumin concentrations in serum by 16.7-40.6%. ZEN also caused reproductive toxicity, including decreased (P < 0.05) 17β-estradiol and increased (P < 0.05) follicle-stimulating hormone concentrations in serum by 12.7-46.3% and induced histopathologic alterations in the liver, ovaries, and uterus. Interestingly, these alterations induced by ZEN were alleviated (P < 0.05) by silymarin supplementation at 100, 200, and 500 mg/kg. Moreover, silymarin supplementation at the 3 doses mitigated (P < 0.05) ZEN-induced impairment in hepatic glutathione peroxidase activity, total antioxidant capacity, and malondialdehyde concentration by 17.6-100%. Meanwhile, silymarin supplementation at all doses upregulated (P < 0.05) phospho-ribosomal protein S6 kinase 1 (p-RPS6KB1) and 3β-hydroxysteroid dehydrogenase (HSD3B) by 43.0-121% but downregulated (P < 0.05) AMP-activated protein kinase (AMPK) and 3α-hydroxysteroid dehydrogenase (HSD3A) in the liver relative to the ZEN group by 11.2-40.6%. In addition, silymarin supplementation at all doses elevated (P < 0.05) HSD3B by 1.8- to 2.5-fold and decreased (P < 0.05) estrogen receptor 1 (ESR1), ATP binding cassette (ABC) c1, and Abcc5 in ovaries and the uterus by 10.7-63.2%. Conclusion Dietary silymarin supplementation at 100, 200, and 500 mg/kg protected rats from ZEN-induced hepatotoxicity and reproductive toxicity, potentially through improvement in the antioxidant capacity and regulation in the genes related to protein synthesis, ZEN metabolism, hormone synthesis, and ABC transporters in the tissues.

Abstract
The objective of this study was to investigate the individual and combined contamination of aflatoxin B₁ (AFB₁), zearalenone (ZEN) and deoxynivalenol (DON) in feedstuffs from different Provinces of China between 2016 and 2017. A total of 1569 samples, including 742 feed ingredients and 827 complete pig feed samples, were collected from various regions of China for mycotoxins analysis. The results showed that individual occurrence rates of AFB₁, ZEN, and DON were more than 83.3%, 88%, and 74.5%, respectively, in all the tested samples. DON was the most prevalent contaminant, followed by ZEN and AFB₁, with the average concentrations ranging from 450.0-4381.5 μg/kg, 2.3-729.2 μg/kg, and 1.3-10.0 μg/kg, respectively. Notable, 38.2%, 10.8%, and 0.6% of complete pig feeds were contaminated with DON, ZEN, and AFB₁ over China's regulatory limits, respectively. Moreover, over 75.0% analyzed samples were co-contaminated with two or three mycotoxins. In conclusion, the current study revealed that the feedstuffs in China were severely contaminated with DON, followed by ZEN and AFB₁ during the past two years. These findings highlight the importance of monitoring mycotoxins in livestock feed and implementing feed management and bioremediation strategies to reduce mycotoxin exposure.

Abstract
Circulating concentration of the essential trace element selenium (Se) was significantly lower in inflammatory disorders. Although Se plays physiological roles mainly through the function of 25 selenoproteins, the response of the selenogenome in immune tissues during inflammatory reactions remains unclear. The objective of this study was to determine the Se retention and selenogenome expression in immune tissues during the lipopolysaccharide (LPS)-induced inflammatory response in porcine. A total of 12 male pigs were randomly divided into two groups and injected with LPS or saline. After 4 h postinjection, blood samples were collected and pigs were euthanized. Pigs challenged with LPS had 36.8 and 16.6 % lower (P < 0.05) Se concentrations in the serum and spleen, respectively, than those injected with saline. Moreover, the activities of GPX decreased (P < 0.05) by 23.4, 26.6, and 30.4 % in the serum, thymus, and lymph node, respectively, in the pigs injected with LPS. Furthermore, the LPS challenge altered (P < 0.05) the mRNA expression of 14, 16, 10, and 6 selenoprotein genes in the liver, spleen, thymus, and lymph node, respectively. Along with 10 previously reported selenoprotein genes, the response of Txnrd2, Txnrd3, Sep15, Selh, Seli, Seln, Selo, Selt, Selx, and Sephs2 to inflammatory reaction in immune tissues were newly illustrated in this study. In conclusion, the LPS-induced inflammatory response impaired Se metabolism and was associated with dysregulation of the selenogenome expression in immune tissues.

Abstract
This study was conducted to determine the effects of aflatoxin B1 (AFB1) on the hepatic transcriptome in ducklings through RNA-sequencing (RNA-Seq). Twenty four, 1-day-old ducklings were divided into 4 treatment groups. Each group received an oral dose of AFB1 at 0, 10, 20, 40 μg/kg BW per day for 2 weeks. Administration of 20 and 40 μg/kg BW of AFB1 significantly decreased body weight, feed intake, serum total protein and albumin, while increasing serum aspartate aminotransferase and alanine aminotransferase activities, and hepatic histopathological lesions. Furthermore, RNA was extracted from the liver of ducklings administrated 0 and 40 μg/kg BW of AFB1. Two RNA-Seq libraries were created from pooled samples and produced over 149 M reads, totaling 14.9 Gb of sequence. Approximately 96,953 predicted transcripts were assembled, 749 of which had significant differential expressions (≥ 2-fold) between the control and AFB1 treatment. GO and KEGG pathway analysis results showed that many genes involved in phase I metabolism, phase II detoxification, oxidation-reduction process, carcinogenesis, apoptosis and cell cycle, and fatty acid metabolism were affected by AFB1 exposure. Conclusion, this study determined the hepatic transcriptome responded to AFB1 exposure, and provide candidate genes can be targeted to prevent and/or reduce aflatoxicosis in ducklings.

Abstract
This study was performed to assess the individual and combined toxic effects of aflatoxin B1 (AFB1), zearalenone (ZEA) and deoxynivalenol (DON) within the liver of mice. A total of 56 4-week-old weanling female mice were divided into seven groups (n = 8). For 2 weeks, each group received an oral administration of either solvent (control), AFB1, ZEA, DON, AFB1 + ZEA, AFB1 + DON or ZEA + DON per day. The results showed that AFB1, ZEA and DON induced liver injury, indicated by elevated relative liver weight, activities of alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST), as well as decreased albumin (ALB) and/or total protein (TP) concentration in the serum. These mycotoxins also decreased hepatic total antioxidant capacity (T-AOC), and/or increased the concentration of malondialdehyde (MDA). Moreover, AFB1 + DON displayed synergistic effects, while AFB1 + ZEA displayed antagonistic effects on those parameters previously described. Furthermore, the apoptotic potential was demonstrated associated with an upregulation of the apoptotic genes Caspase-3 and Bax, along with a downregulation of the antiapoptotic gene Bcl-2 in liver. In conclusion, this study provides a better understanding of the toxic effects of AFB1, ZEA, DON, alone or in combinations on the liver of mice, which could contribute to the risk assessment of these mycotoxins in food and feed.

Abstract
Two experiments were conducted to screen microorganisms with aflatoxin B1 (AFB1 ) removal potential from soils and to evaluate their ability in reducing the toxic effects of AFB1 in ducklings. In experiment 1, we screened 11 isolates that showed the AFB1 biodegradation ability, and the one exhibited the highest AFB1 removal ability (97%) was characterized and identified as Cellulosimicrobium funkei (C. funkei). In experiment 2, 80 day-old Cherry Valley ducklings were divided into four groups with four replicates of five birds each and were used in a 2 by 2 factorial trial design, in which the main factors included administration of AFB1 versus solvent and C. funkei versus solvent for 2 weeks. The AFB1 treatment significantly decreased the body weight gain, feed intake and impaired feed conversion ratio. AFB1 also decreased serum albumin and total protein concentration, while it increased activities of alanine aminotransferase and aspartate aminotransferase and liver damage in the ducklings. Supplementation of C. funkei alleviated the adverse effects of AFB1 on growth performance, and provided protective effects on the serum biochemical indicators, and decreased hepatic injury in the ducklings. Conclusively, our results suggest that the novel isolated C. funkei strain could be used to mitigate the negative effects of aflatoxicosis in ducklings.

Abstract
BACKGROUND The involvement of cytochrome P450 (CYP450) isozymes and the selenogenome in selenium-mediated protection against aflatoxin B1 (AFB1)-induced adverse effects in broilers remains unclear. OBJECTIVE This study was designed first to determine whether selenium could reduce AFB1-induced hepatotoxic effects and then to determine whether these effects were due to changes in the CYP450 isozymes and selenogenome expression in the liver of chicks. METHODS Male avian broilers (aged 120 d) were allocated to 4 groups with 5 replicates of 6 birds to be included in a 2-by-2 factorial trial in which the main factors included supplementation of AFB1 (<5 compared with 100 μg/kg) and selenium (0.2 compared with 0.5 mg/kg) in a corn/soybean-based diet for 4 wk. Serum biochemistry, hepatic histology, and mRNA and/or activities of hepatic antioxidant enzymes, CYP450 isozymes, and 26 selenoproteins were analyzed at week 2 and/or 4. RESULTS Administration of AFB1 induced liver injury, decreasing (P < 0.05) total protein and albumin concentrations by 33.3-43.8% and increasing (P < 0.05) alanine aminotransferase and aspartate aminotransferase activities by 26.0-33.8% in serum, and induced hepatic necrosis and bile duct hyperplasia at week 2. AFB1 also decreased (P < 0.05) hepatic activities of glutathione peroxidase (GPX), thioredoxin reductase (TXNRD), and catalase, and the glutathione concentration by 13.1-59.9% and increased (P < 0.05) malondialdehyde, 8-hydroxydeoxyguanosine and exo-AFB1-8,9-epoxide (AFBO) DNA concentrations by 17.9-1200%. In addition, the mRNA and activity of enzymes responsible for the bioactivation of AFB1 into AFBO, which included CYP450 A1, 1A2, 2A6, and 3A4, were significantly induced (P < 0.05) by 29.2-271% in liver microsomes after 2-wk exposure to AFB1. These alterations induced by AFB1 were prevented by selenium supplementation. Dietary selenium supplementation increased (P < 0.05) mRNA and/or activities of 6 selenoprotein genes (Gpx3, Txnrd1, Txnrd2, Txnrd3, iodothyronine deiodinase 2, and selenoprotein N) in the liver of AFB1-treated groups at week 2. CONCLUSIONS Dietary selenium protected chicks from AFB1-induced liver injury, potentially through the synergistic actions of inhibition of the pivotal CYP450 isozyme-mediated activation of AFB1 to toxic AFBO, and increased antioxidant capacities by upregulation of selenoprotein genes coding for antioxidant proteins.

Abstract
This study was performed to determine the individual and combined cytotoxic effects of Aflatoxin B1 (AFB1), zearalenone (ZEA), deoxynivalenol (DON) and fumonisin B1 (FB1) on BRL 3A rat liver cells. After the mycotoxins treated the BRL 3A cells for 12, 24 and 48 h, cell viability was determined using the MTT assay. The cytotoxicity of individual mycotoxins on BRL 3A cell viability in decreasing order were DON > AFB1 > ZEA > FB1. The central composite design (CCD) was used to assess the toxicity of binary and ternary mixtures of these mycotoxins. The mixtures of AFB1+ZEA and AFB1+DON showed the synergetic toxic effects on BRL 3A cells. These toxins decreased the viability of cells by inducing intracellular reactive oxygen species (ROS) production and promoting apoptosis in the BRL 3A cells. This effect was mediated by an upregulation of the stress and apoptotic genes Hsp70, p53, Bax, Caspase-3 and Caspase-8, along with a downregulation of the antiapoptotic gene Bcl-2. In conclusion, our results suggested that the coexistence of AFB1 and ZEA or DON in agricultural products could be more hepatotoxic than individually, suggests that the toxicological interactions of these toxins need to be better understood to assess health risks.

Abstract
Tin (Sn) is widely used in daily life and distributed in many tissues and nutrients. Although over-ingestion of Sn can cause health problems, relatively little attention has been given to the toxic effects of Sn in livestock health and productivity. This study was performed to investigate the toxic effects of prolonged high intake of dietary Sn on broilers. 150 one-day-old Avian broilers were randomly divided into five treatment groups, with five replicates of six birds. For 6 weeks, each group was fed a corn-soybean basal diet (BD) or BD + Sn (as SnCl2) at 120, 240, 480, or 720 mg/kg, respectively. Compared with the control, hepatic glutathione peroxidase (GPX) and superoxide dismutase (SOD) activities were significantly decreased when supplemented with Sn up to 480 mg/kg, while malondialdehyde (MDA) was increased until Sn supplementation at 720 mg/kg. Moreover, dietary Sn supplementation at 720 mg/kg decreased BW gain, feed intake, and impaired feed conversion ratio. The 720 mg Sn/kg group also increased activities of alkaline phosphatase (AKP), while decreased hemoglobin (HGB), red blood cell (RBC), and hematocrit (HCT) in the blood. Furthermore, the accumulation of Sn in various tissues was dose dependent on Sn ingestion. It was found that the tibia and feather are the two main tissues for Sn accumulation, followed by the liver, kidney, and other tissues in broilers. In conclusion, the adverse effects on broilers were induced when diets supplemented with Sn up to 480 mg/kg. Sn levels also managed to accumulate in the tibia and feather of broilers.

Abstract
The aim of the present study was to evaluate the protective effects of isoflavone (ISO) against zearalenone (ZEA) residues in the muscle and liver tissues of prepubertal gilts. Seventy 75-day-old, prepubertal, female pigs (Duroc × Landrace × Yorkshire, 26.5 ± 0.60 kg) were allocated randomly to seven diet treatments for 21days as follows: one control group (fed the basal diet) and six groups fed the basal diet with the addition of either 0.5 or 2.0 mg/kg ZEA plus either 0, 300 or 600 mg/kg ISO. The results showed that the diet with 2.0 mg/kg ZEA added caused an increase of ZEA residue level in muscle tissue (P < 0.05), and that the addition of both 0.5 and 2.0 mg/kg ZEA increased the residue level of ZEA in the liver of prepubertal gilts (P < 0.05). Addition of 600 mg/kg ISO to 2.0 mg/kg ZEA-contaminated diet decreased the ZEA residue level in liver tissue (P < 0.05), and the addition of 300 or 600 mg/kg ISO to the 2.0 mg/kg ZEA-contaminated diet decreased the residue levels of ZEA in muscle tissue (P < 0.05). Western blot analysis demonstrated that feeding ZEA to prepubertal gilts increased their protein expression of 3α/3β-hydroxysteroid dehydrogenase (HSD; P < 0.05), and that the addition of 300 or 600 mg/kg ISO to the 2.0 mg/kg ZEA-contaminated diet decreased the protein expression of 3α/3β-HSD (P < 0.05), compared with the addition of 2.0 mg/kg ZEA alone. The results demonstrated that muscle and liver tissues retain residual ZEA when pigs are fed a diet contaminated with high concentrations of ZEA, and that the concentration of ZEA in muscle and liver tissues increased with increased amounts of ZEA in the feed. In diets contaminated with high levels of ZEA, the addition of ISO may accelerate the biotransformation and degradation of ZEA and its metabolites, and reduce the residues of ZEA in liver and muscle tissues of prepubertal gilts.

Abstract
The aim of the present research was to determine the interactive effect of zearalenone (ZEA) and soybean isoflavone (ISO) on the growth performance, development of organs and serum parameters in prepubertal gilts. Ninety 75-day-old female pigs (Duroc × Landrace × Yorkshire, 26.5 ± 0.60 kg) were randomly allocated to nine diet treatments during the 21-day study. The experiment employed a 3 × 3 factorial design using a non-soybean meal diet with the addition of 0, 0.5 or 2.0 mg/kg ZEA and 0, 300 or 600 mg/kg ISO. The results indicated that simultaneous addition of ZEA and ISO had no significant influence on the growth performance in prepubertal gilts. Zearalenone with 2 mg/kg increased (p < 0.05) the relative weight of the reproductive organs (including uterus and vagina) but had no obvious effects (p > 0.05) on the relative weight of the heart, liver, lung, kidney and spleen. Isoflavone at 600 mg/kg could offset the increased weight of the reproductive organs induced by ZEA. Simultaneous addition of ZEA and ISO to prepubertal gilts increased the level of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase in the serum (p < 0.05) at day 14 but their levels decreased (p < 0.05) over time. Zearalenone increased the level of malondialdehyde and decreased the concentrations of superoxide dismutase and glutathione peroxidase (p < 0.05) in the serum. The results suggested that ISO added to diets at 600 mg/kg could reduce the increase in the relative weight of reproductive organs and relieve the oxidative stress induced by ZEA added at 2 mg/kg during the growth phase in prepubertal gilts.

Abstract
The aim of the present study was to investigate the interactive effect of zearalenone (ZEA) and soybean isoflavone (ISO) on the development of reproductive organs, reproductive hormones and estrogen receptor expression in prepubertal gilts. Ninety 75-day-old female pigs (Duroc × Landrace × Yorkshire, 26.50 ± 0.60 kg) were randomly allocated to nine diet treatments during the 21 day study. The experiment employed a 3 × 3 factorial design using a non-soybean meal diet with addition of 0, 0.5 or 2.0mg/kg ZEA and 0, 300 or 600 mg/kg ISO. The results indicated that diets supplemented with 600 mg/kg ISO could reduce the increased weight of the reproductive organs induced by ZEA at 2mg/kg (P<0.05) while feed containing ISO and 0.5mg/kg ZEA increased the weight of the reproductive organs compared with pigs fed diets with 0.5mg/kg ZEA alone. Diets with ISO at 600 mg/kg reduced the large width of vulvas induced by diets with 2mg/kg ZEA (P<0.05). Simultaneous provision of ZEA and ISO to prepubertal gilts increased the level of E2 at days 7 and 14, but decreased it at day 21 (P<0.05). Pigs simultaneously fed 2mg/kg ZEA and 600 mg/kg ISO had the highest level of FSH (P<0.05). There was a significant interaction (P<0.05) between ZEA and ISO supplementation on the level of LH, and pigs offered diets with 2mg/kg ZEA and 600 mg/kg ISO had the lowest level of LH on days 14 and 21. Animals supplemented simultaneously with ZEA and ISO showed higher ERα/ERβ mRNA expression compared to those offered diets containing 0.5mg/kg ZEA alone or basal diets. However, this simultaneous supplementation resulted in a lower level of ERα/ERβ mRNA expression compared to offering diets with 2mg/kg ZEA alone. It appears that ISO can counteract the estrogenic influence of a high dosage of ZEA (2mg/kg). This affect might be attributed to competitive binding with estrogen receptors, thereby weakening the estrogenic effect of ZEA. Meanwhile, interactions between ZEA and ISO may interfere with the functioning of E2, FSH and LH in prepubertal gilts.

Abstract
The study was to determine effects of dietary supplementation of chitosan (COS) and galacto-mannan-oligosaccharides (GMOS) on some serum biochemical indices, serum growth hormone (GH) and insulin-like growth factor-I (IGF-I) levels, and hepatic and long gissimus muscle IGF-I mRNA expression in early-weaned piglets. Twenty six Duroc x Landrace x Yorkshire piglets at the age of 15 days were used. The piglets had access to creep feed during the suckling. Six piglets were sacrificed for sampling at the beginning of the study. The other 20 piglets were individually housed in metabolic cages and randomly allotted to four corn and soybean meal-based diets including the control group, the antibiotic group with 110 mg lincomycin/kg diet, the COS group containing 0.025% COS, and the GMOS group with 0.20% GMOS, respectively, in a 2-week feeding experiment. Blood urea nitrogen (BUN) level was reduced whereas serum total protein concentration was increased (P<0.05) in responses to the COS and GMOS supplementation. Dietary supplementation of COS and GMOS also increased (P<0.05) the serum GH and IGF-I levels along with enhanced hepatic and the muscle IGF-I mRNA abundance. Dietary supplementation of oligosaccharides such as COS and GMOS may improve growth and feed conversion efficiency by increasing plasma GH and IGF-I levels, in the early-weaned piglets.
