The increased use of slow-release organic acids in swine nutrition has prompted more research to assess their possible role in modulating the intestinal microflora as an alternative to antibiotics. Three diets for growing pigs containing 0 (L-NDF), 100 (M-NDF), and 200 g kg-1 (H-NDF) dried sugar beet pulp (SBP) were pre-digested to simulate ileal digestion, and used as substrate in an in vitro cecal fermentation study. The inoculum was collected from pigs immediately after slaughter. Diets tested were L-NDF, M-NDF, and H-NDF with or without the addition of an organic acid blend providing phosphoric, citric, fumaric, and malic acid at 1.53, 0.78, 2.59, and 1.12 mmol L-1, respectively. Cecal microbial growth was monitored using the cumulative gas production technique. Fermentation fluid was analyzed for ammonia and volatile fatty acids concentrations. The maximum rate of gas production was higher when H-NDF rather than L-NDF or M-NDF (+ 18%; P < 0.05) was fed; such a high rate of growth (+ 14%; P < 0.05) was also achieved when the acid blend was added to L-NDF. After 24 h, the acid blend reduced ammonia, isoacids, and acetic acid concentrations in fermentation fluid regardless of the type of diet (P < 0.05). Organic acids stimulated bacterial fermentation when added to a low-fiber diet and were able to reduce ammonia in all diets tested.

AbstractConstructing heterojunction is a promising way to improve the charge transfer efficiency and can thus promote the electrochemical properties. Herein, a facile and effective epitaxial-like growth strategy is applied to NiSe2 nano-octahedra to fabricate the NiSe2-(100)/Ni(OH)2-(110) heterojunction. The heterojunction composite and Ni(OH)2 (performing high electrochemical activity) is ideal high-rate battery-type supercapacitor electrode. The NiSe2/Ni(OH)2 electrode exhibits a high specific capacity of 909 C g−1 at 1 A g−1 and 597 C g−1 at 20 A g−1. The assembled asymmetric supercapacitor composed of the NiSe2/Ni(OH)2 cathode and p-phenylenediamine-functional reduced graphene oxide anode achieves an ultrahigh specific capacity of 303 C g−1 at 1 A g−1 and a superior energy density of 76.1 Wh kg−1 at 906 W kg−1, as well as an outstanding cycling stability of 82% retention for 8000 cycles at 10 A g−1. To the best of our knowledge, this is the first example of NiSe2/Ni(OH)2 heterojunction exhibiting such remarkable supercapacitor performance. This work not only provides a promising candidate for next-generation energy storage device but also offers a possible universal strategy to fabricate metal selenides/metal hydroxides heterojunctions.
