Dietary DON contamination negatively affects feed intake, growth, and health status in all stages of swine production. Both <i>in vivo</i> biotransformation, including somatic xenobiotic metabolism and microbial metabolism, and <i>ex vivo</i> chemical mitigation reactions, such as bisulfite-based sulfonation, have been shown to reduce the reactivity and bioavailability of DON in pigs. However, the influences of age and maturation on the disposition of DON and its chemical mitigation in pigs have not been examined in detail. The objective of the current study was to evaluate growth performance and the metabolomic profiling of DON and its derivatives in feeds, feces, and urine through two feeding trials. In a 21-day nursery trial, 4 groups of pigs (<i>n</i> = 12/group) were fed low- and high-dose DON with and without 0.25% Notox D, a bisulfite agent. In a 49-day finishing trial, 5 groups of pigs (<i>n</i> = 12/group) were fed the DON-contaminated feed without a mitigant, or with 0.25% Notox D, and 0.25%, 0.50%, and 0.75% sodium metabisulfite. The performance results showed that sulfonation treatment restored the growth of nursery pigs under the high-dose DON exposure (3.7 ppm), but there was no difference in pig growth under the low-dose DON exposure (0.8 ppm for nursery pigs and 1.2 ppm for finishing pigs). Metabolomic profiling indicated that finishing pigs were more capable than nursery pigs in the microbial conversion of DON to deepoxy-deoxynivalenol (DOM), DOM absorption, and somatic production of their glucuronides. Bisulfite agents effectively and dose-dependently decreased DON in pig feeds by forming DON sulfonates (DON-S), which were further enriched and concentrated in feces. The decreases of free and total DON in urine after sulfonation treatment were correlated with the improved growth performance in nursery pigs. Overall, these results revealed extensive interactions among maturation, DON disposition, and sulfonation treatment in pigs and hence warrant further investigations to establish the reference values on the age of pigs, the level of DON contamination, and the dose of bisulfite agents to guide the mitigation practices in swine production.</p>","PeriodicalId":93846,"journal":{"name":"ACS agricultural science & technology","volume":"5 3","pages":"391–401 391–401"},"PeriodicalIF":2.3,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143631513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Under the action of mechanical force, the TA-Fe complex formed by tannic acid (TA) and Fe³⁺ is uniformly coated on the surface of the uniconazole particles. The effects of grinding tank materials (agate and zirconia) and dry and wet grinding on the morphology and particle size of the capsules are systematically studied. Due to the different energies carried by different density media, there are differences in the shape and size of micro/nano capsules prepared by dry grinding using agate (AD) and zirconia (ZD) grinding media. The optimized UZ@TA-Fe(ZD) nanocapsules demonstrate high loading content (89.3%) and small size characteristics (467.1 nm). Field trials showed that UZ@TA-Fe(ZD) nanocapsules were superior to commercial wettable powder products in promoting bud formation and increasing cotton yield.

In this study, a multicomponent oxide glass is formulated for the nutritional Palisade grass (cv Piatã), used as a model for nutrients released in greenhouse experiments. The GF composition, which included P₂O₅–SiO₂–B₂O₃–CaO–K₂O–MgO–MnO₂–MoO₃–ZnO, was melted, cooled into a glass, and comminuted into grains with a particle size distribution between 0.85 and 2.0 mm in diameter. The GF solubility was previously evaluated through immersion in deionized water and citric acid-sodium citrate buffer solutions at different pH levels at 25 °C for 64 h. The undissolved glass fractions were analyzed using X-ray fluorescence (XRF), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), infrared spectroscopy (FTIR), and Raman. The nutrient release rates, solubility, and results from five sequential harvests of Palisade grass were analyzed using inductively coupled plasma optical emission spectrometry (ICP-OES). The previous study reveals a slow release of nutrients through two dissolution mechanisms, ion exchange and hydrolysis reactions. Greenhouse experiments showcased the gradual release of nutrients and highlighted GF’s efficiency in providing a continuous nutrient supply from a single fertilization. Compared with experiments using soluble salts in the same amount of the GF, it consistently produced a higher dry matter yield (DMY) than the control.
