Abstract The objective of this study was to evaluate the modified hydrated sodium calcium aluminosilicate (HSCAS) adsorbent ability to reduce the toxicity of T-2 toxin in broilers. 96 one-day-old male broilers were randomly allocated to 4 experimental groups with 4 replicates of 6 birds each. The four groups 1–4 were received the basal diet (BD), BD plus 6.0 mg/kg T-2 toxin, BD plus 6.0 mg/kg T-2 toxin with 0.05% modified HSCAS adsorbent, BD plus 0.05% modified HSCAS adsorbent, respectively, for 2 weeks. The growth performance, nutrients digestibility, and digestive tract histopathology were analyzed. Compared with the control group, dietary supplementation of T-2 toxin decreased (P < 0.05) body weight gain, feed intake and feed conversion by 11.4–31.8% during d 1–7, d 8–14 and d 1–14. Dietary supplementation of T-2 toxin also decreased (P < 0.05) the apparent metabolic rate of crude protein, calcium, and total phosphorus by 14.9–16.1% during d 8–14. These alterations induced by T-2 toxin were mitigated or prevented (P < 0.05) by the supplementation of the modified HSCAS adsorbent. Meanwhile, dietary modified HSCAS adsorbent supplementation also prevented (P < 0.05) T-2 toxin-induced morphological changes and damage, such as severe degeneration and desquamation of the villous epithelial cells, congestion in intestinal lamina propria, and edema and thicken in the serosa with infiltration of numerous lymphoid cells, in the gizzard, duodenum, jejunum, and ileum of broilers. Notably, dietary supplementation of the modified HSCAS adsorbent alone did not affect (P > 0.05) any of those parameters. In conclusion, these findings indicate this novel HSCAS could be used as a promising adsorbent for protecting against T-2 toxin-induced toxicity in chicks (This work was supported in part by the National Key Research and Development Program of China, Projects 2018YFD0500601 and 2016YFD0501207).

We reviewed various dietary strategies to contain the toxic effects of mycotoxins using antioxidant compounds (selenium, vitamins, provitamins), food components (phenolic compounds, coumarin, chlorophyll and its derivatives, fructose, aspartame), medicinal herbs and plant extracts, and mineral and biological binding agents (hydrated sodium calcium aluminosilicate, bentonites, zeolites, activated carbons, bacteria, and yeast). Available data are primarily from in vitro studies and mainly focus on aflatoxin B1, whereas much less information is available about other mycotoxins. Compounds with antioxidant properties are potentially very efficacious because of their ability to act as superoxide anion scavengers. Interesting results have been obtained by food components contained in coffee, strawberries, tea, pepper, grapes, turmeric, Fava tonka, garlic, cabbage, and onions. Additionally, some medicinal herbs and plant extracts could potentially provide protection against aflatoxin B1 and fumonisin B1. Activated carbons, hydrated sodium calcium aluminosilicate, and bacteria seem to effectively act as binders. We conclude that dietary strategies are the most promising approach to the problem, considering their limited or nil interference in the food production process. Nevertheless, a great research effort is necessary to verify the in vivo detoxification ability of the purposed agents, their mode of action, possible long-term drawbacks of these detoxification-decontamination procedures, and their economical and technical feasibility.

AbstractMammalian oocytes represent impaired quality after undergoing a process of postovulatory aging, which can be alleviated through various effective ways such as reagent treatment. Accumulating evidences have revealed the beneficial effects of astaxanthin (Ax) as a potential antioxidant on reproductive biology. Here, porcine matured oocytes were used as a model to explore whether Ax supplement can protect against oocyte aging in vitro and the underlying mechanism, and therefore they were cultured with or without 2.5 μM Ax for an additional 24 h. Aged oocytes treated with Ax showed improved yield and quality of blastocysts as well as recovered expression of maternal genes. Importantly, oxidative stress in aged oocytes was relieved through Ax treatment, based on reduced reactive oxygen species and enhanced glutathione and antioxidant gene expression. Moreover, inhibition in apoptosis and autophagy of aged oocyte by Ax was confirmed through decreased caspase-3, cathepsin B and autophagic activities. Ax could also maintain spindle organization and actin expression, and rescue functional status of organelles including mitochondria, endoplasmic reticulum, Golgi apparatus and lysosomes according to restored fluorescence intensity. In conclusion, Ax might provide an alternative for ameliorating the oocyte quality following aging in vitro, through the mechanisms mediated by its antioxidant properties.

Since microfollicular environment and the size of the follicle are important markers influencing oocyte quality, the aim of this study is to present the spectral characterization of oocytes isolated from follicles of various sizes using lab-on-chip (LOC) technology and to demonstrate how follicle size may affect oocyte quality. Porcine oocytes (each,n=100) recovered from follicles of different sizes, for example, from large (>5 mm), medium (3–5 mm), and small (<3 mm), were analyzed after precedingin vitromaturation (IVM). The LOC analysis was performed using a silicon-glass sandwich with two glass optical fibers positioned “face-to-face.” Oocytes collected from follicles of different size classes revealed specific and distinguishable spectral characteristics. The absorbance spectra (microspectrometric specificity) for oocytes isolated from large, medium, and small follicles differ significantly (P<0.05) and the absorbance wavelengths were between 626 and 628 nm, between 618 and 620 nm, and less than 618 nm, respectively. The present study offers a parametric and objective method of porcine oocyte assessment. However, up to now this study has been used to evidence spectral markers associated with follicular size in pigs, only. Further investigations with functional-biological assays and comparing LOC analyses with fertilization and pregnancy success and the outcome of healthy offspring must be performed.
