Simple SummaryAntibiotics are banned in animal feed, and substances used to replace antibiotics are being found continuously.Yucca schidigera,Quillaja saponaria, andYucca saponinare natural plants and their components, which have many beneficial health functions for animals, are suitable as animal feed additives to replace antibiotics. By comparing the impacts of three substances on the growth, immunity, and intestinal health of broilers, this study found thatYucca schidigera,Quillaja saponaria, andYucca saponinall promote the healthy growth of broilers, andYucca saponinhas better effects than the other two substances.AbstractThe purpose of this study is to investigate the effects ofYucca saponin(YSa),Yucca schidigera(YS), andQuillaja Saponaria(QS) on growth performance, nitrogen metabolism, immune ability, antioxidant capability, and intestinal flora of yellow-feather broilers. This study randomly divided a total of 480 1-day yellow-feather broilers into 4 treatment groups. Factors in the 4 groups included CON group (basic diet), YSa group (basic diet mixed with 500 mg/kg YSa), YS group (basic diet mixed with 500 mg/kg YS), and QS group (basic diet mixed with 500 mg/kg QS). Throughout the 56-day study period, YSa, YS, and QS groups had higher average daily gain in broilers than the CON group (p< 0.01). The YS group had a lower feed gain ratio (F: G) in broilers than the CON group (p< 0.05). YSa, YS, and QS showed increased serum immunoglobin A (IgA), immunoglobin Y (IgY), immunoglobin M (IgM), and total antioxidant capacity (T-AOC) levels; enhanced acetic acid, butyric acid, and valeric acid levels of cecal content; and reduced contents of ammonia nitrogen, urea nitrogen, interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), and malondialdehyde (MDA) in serum in broilers (p< 0.05). The relative abundance of Lachnoclostridium in the QS group was decreased compared with that in the CON group (p< 0.05). Higher IgA and IgY sera contents were observed in the YS group compared to the YSa and QS groups (p< 0.05). In contrast with the QS group, the serum IL-6 concentration of the YS group was reduced (p< 0.05). In conclusion, YSa, YS, and QS promoted growth performance, nitrogen metabolism, immunity, antioxidant capability, and intestinal flora in broilers. Through the comparison of YSa, YS, and QS, it was found that YS is more suitable as a feed additive to ameliorate the healthy growth of broilers.Keywords:Yucca saponin;Quillaja saponaria;yellow-feather broilers;growth performance;intestinal flora

With the combination of molecular simulation and relevant experiments, the efficient Brønsted-Lewis acidic ionic liquid (IL) was designed and synthesized for biodiesel production from soapberry oil. In molecular simulation, 4-methylthiazole (MT) is proved to be the best matrix for IL preparation via electrostatic potential analysis and proton affinity analysis, and it also is verified by experiments. In orthogonal experiment, the relationship in catalytic activity between Brønsted-Lewis acidic IL and corresponding materials (Brønsted acidic IL and metal chloride) was revealed. Meanwhile, [Ps-MTH][CF 3 SO 3 ] and FeCl 3 are verified as the best materials for preparation of Brønsted-Lewis acidic IL, and [Ps-MTH][CF 3 SO 3 ]-FeCl 3 ( x = 0.65) is determined as the most efficient catalyst in the end. The Lewis acidity, Brønsted acidity and interaction of [Ps-MTH][CF 3 SO 3 ] and FeCl 3 in [Ps-MTH][CF 3 SO 3 ]-FeCl 3 ( x = 0.65) were characterized by FT-IR. And the catalytic mechanism of transesterification catalyzed by prepared IL was clarified. In order to maximize the biodiesel yield, optimization of process variables was conducted using Box-Behnken response surface methodology. The 97.04% of high biodiesel yield is obtained under the optimum conditions: reaction temperature was 127 °C, molar ratio (methanol to soapberry oil) was 27.96:1, catalyst amount was 3.06 mmol and reaction time was 8 h. Furthermore, [Ps-MTH][CF 3 SO 3 ]-FeCl 3 ( x = 0.65) presents good catalytic activity in different transesterification for biodiesel production. And its catalytic activity decreases from 97.04% to 93.59% after being used for 5 times, which reflects good reusability. The main properties of soapberry biodiesel were also measured and compared to the ASTM D6751 standard.

Usually, traditional poly (ionic liquid)s are prepared to nanoparticles with high surface areas for achieving a quasi-homogeneous reaction system. In this work, a novel poly (ionic liquid) P(VB-VS)HSO 4 , synthesized by simply using ionic liquids immobilized on the 1-vinylimidazole-based crosslinked copolymer microsphere, was used as heterogeneous catalyst for transesterification of a novel non-edible feedstock soapberry oil to biodiesel. The structure, thermal stability and wetting property characteristics of the crosslinked copolymer microsphere particles and poly (ionic liquid) microspheres were investigated. The results indicated that ionic liquids were successfully functionalized on crosslinked copolymer microsphere, and P(VB-VS)HSO 4 possessed high surface areas (100.1 m 2 /g), abundant meso -macropores (with diameter of ∼18.9 nm), good mechanical strength (81 N) and superior thermal stability. Benefiting from the unique structure features, these poly (ionic liquid) microspheres manifested excellent catalytic performance for transesterification of soapberry oil with methanol. A maximum fatty acid methyl esters (FAMEs) yield of 95.2% could be obtained under the response surface methodology (RSM) optimized conditions of 8.0 h reaction time, 29.1 methanol to oil molar ratio, and 8.7 wt% catalyst amount. Impressively, it was also efficient for the esterification of oleic acid, giving methyl oleate yield of 97.5%. Catalytic tests exhibited that P(VB-VS)HSO 4 presented high catalytic activity and good reusability in comparison with traditional acid catalysts. The main physicochemical of the obtained soapberry biodiesel met the biodiesel standard ASTM D6751 . Therefore, this work provides a cheap and facile route to the synthesis of size-controlled poly (ionic liquid) microspheres (the diameter of the catalyst was about 500 μm) for catalyzing the production of clean biofuels.

This study develops a catalytic system using pyruvic acid (PYA) and Fe2+ to efficiently coproduce xylo-oligosaccharides (XOS) and (manno-oligosaccharides) MOS from food material (Gleditsia sinensis Lam. fruit.) and its waste peel, respectively. The system achieved maximum yields of 67.12% XOS and 57.32% MOS without toxic byproducts such as furfural and 5-hydroxymethylfurfural (5-HMF) below 130 °C. The process employs a two-stage mechanism, where PYA cleaves galactose side chains and xylan backbones, while Fe2+ stabilizes β-1,4-glycosidic bonds, resulting in polymerization degree ratios of X2–3/X4–5 at 0.975 and M2–3/M4–5 at 0.96. The composite oligosaccharides, PFMX, showed significant prebiotic effects, enhancing Bifidobacterium adolescentis growth to 3.4 × 108 CFU/mL─144% higher than commercial fructooligosaccharides (FOS). The concentration of short-chain fatty acids (SCFAs) was 15.09 g/L, with specific products propionic acid (1.44 g/L) and butyric acid (0.15 g/L). PFMX effectively regulates substrate utilization and SCFA metabolism, offering a promising strategy for developing functional foods that target gut inflammation.
