“…Some researchers have reported modified MMT materials with antibacterial activity. For example, silver, copper, and zinc ions have been immobilized on MMT [4][5][6][7][8][9], and cetylpyridinium, cetyltrimethylammonium [10][11][12], tetradecyltrimethylammonium [13], chitosan [14,15], and chlorhexidine acetate [16] have been intercalated into the MMT layers. In addition, pharmacology studies have revealed that MMT can adsorb to bacteria such as Escherichia coli (E. coli), Staphylococcus aureus (S. aureus), and immobilized cell toxins [17,18].…”

Nanocomposites of Ag with organic montmorillonite (Ag-OMMT), Ag with montmorillonite (Ag-MMT), and organic montmorillonite (OMMT) were successfully prepared via a one-step solution-intercalated method. Sodium MMT, silver nitrate, and dimethyl octadecyl hydroxy ethyl ammonium nitrate were used as precursors. X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, and energy dispersive spectroscopy analyses confirmed that the MMT layers were intercalated, and Ag + was partly reduced to silver nanoparticles with diameters within 10-20 nm in Ag-OMMT. The decomposition temperature of the organic cations in OMMT and Ag-OMMT increased to 220 ∘ C, as revealed by differential scanning calorimetrythermogravimetric analysis. The antimicrobial activity of the nanocomposites was tested by measuring the minimum inhibitory concentration (MIC) and killing rate. The MICs of Ag-OMMT against Staphylococcus aureus, Escherichia coli, and Candida albicans were 0.313, 2.5, and 0.625 mg/mL, respectively. Because of the presence of quaternary ammonium nitrate, Ag-OMMT has a better MIC against Gram-positive bacteria compared to Gram-negative bacteria and fungi. OMMT did not show antimicrobial activity against Escherichia coli and Candida albicans. In 2 h, 0.0125 mg/mL Ag-OMMT could kill 100% of S. aureus, E. coli, and C. albicans in solution, and Ag-MMT could kill 99.995% of S. aureus, 90.15% of E. coli, and 93.68% of C. albicans. These antimicrobial functional nanocomposites have the potential for application in the area of surface decoration films.

“…It is also reported that adding montmorillonite to the feed did not improve the growth performance of pigs (Xia et al, 2005;Song et al, 2012). Interestingly, relying on the adsorption of montmorillonite, feeding montmorillonite loaded with copper and zinc ions, which are beneficial to growth, showed a significant improvement in the growth performance of pigs (Jiao et al, 2015(Jiao et al, , 2018; this is an indication that the single addition of montmorillonite has a limited effect on improving the growth performance of weaned piglets.…”

The study investigated the impact of dietary montmorillonite on the growth performance, intestinal mucosal barrier, and microbial community in weaned piglets with control group (CON) and dietary supplementation of 0.2% montmorillonite (0.2% M). Compared with the CON group, 0.2% M feed in the diet increased the average daily gain (ADG) on days 15–35 and day 1–35 and the average daily feed intake on days 1–35 (ADFI) (0.05 < P < 0.1). Besides, higher villus height of the duodenum and jejunum and lower crypt depth of duodenum and colon were revealed in the 0.2% M group than in the CON group (P < 0.05). Moreover, the V/C (ratio of the villus height and crypt depth) in the 0.2% M group was increased compared to that in the CON group both from the duodenum and ileum (P < 0.05). The relative mRNA expression of mucin-1, ITGB1 (β1-integrins), and PKC (protein kinase C) of ileum in the 0.2% M group were upregulated (P < 0.05) compared to that in the CON group. The digesta sample of ileum from piglets in the 0.2% M group contained greater (P < 0.05) intestinal bacterial diversity and abundances of probiotics, such as Streptococcus, Eubacterium_rectale_group, and Lactobacillus, which could promote the synthesis of carbon-containing biomolecules. Overall, dietary supplementation of 0.2% M was shown to have a tendency to improve the growth performance of weaned piglets and may enhance their intestinal mucosal barrier function via altering the gut microbiota.

Simple SummaryFeeds contaminated by mycotoxins cause organ damage, immune suppression and health disorders, limiting growth and performance of farm animals. One of the most practical approaches to minimizing the negative effect of these substances in livestock diets is by the use of different feed additives, preventing their absorption from the gastrointestinal tract. Growing interest in particular is applied to mineral additives, such as clays and clay minerals. These materials are not digested but bind toxic metabolites and mycotoxins, moving them through the digestive tract, without detrimental influence on the animal body. Apart from the binding capacity, clay minerals show other activity which could positively affect animal welfare and productivity. However, each type of clay has its own specific binding capacity that can greatly vary according to its origin deposit and treatment. Moreover, clays may bind with not only noxious substances but also some nutrients, causing a nutritional imbalance for animals. Therefore, the aim of the review was to present the available knowledge on the properties and use of clays in feedstuff decontamination as well as to discuss the resulting potential benefits for animal health and safety of human food.AbstractThe contamination of feeds with microbiological or toxicological agents can affect health, productivity and safety of livestock animals and their products. The treatment of feedstuffs to lower the content of undesired substances before feeding is expensive and labor intensive, therefore an alternative is to reduce their gastrointestinal absorption. Different feed additives are available, however the use of clays and clay minerals are ideal for this purpose due to their high specific surface area, adsorption capacity, low or null toxicity for the animal and low cost. A large number of clays available to producers have different structures that are dependent on their mining source, causing difficulty in proper categorization. For this reason properties of phyllosilicates with 1:1 layers (one sheet of SiO4 tetrahedra joined to one sheet of Al- or Mg-octahedra), 2:1 layers (one sheet of Al- or Mg-octahedra between two sheets of Si-tetrahedra), and 2:1:1 layers (a basic 2:1 structure with an interlayer brucite (with cations Mg2+ or Fe2+) or gibbsite (with cation Al3+) sheet) and tectosilicates are described. The role of clay minerals in animal production shows a reduction in diarrhea, better feed conversion ratio, and improved health of many livestock species due to their specific adsorption potential of many feed mycotoxins. Overall, there is growing interest in the use of clays due to their beneficial characteristics, absence of primary toxicity and success in research to reduce animal disease and improve animal production and safety of animal products.
