| 1 | Co-fermented defatted rice bran alters gut microbiota and improves growth performance,antioxidant capacity,immune status and intestinal permeability of finishing pigs显示文摘Based on preparation of co-fermented defatted rice bran(DFRB)using Bacillus subtilis,Saccharomyces cerevisiae,Lactobacillus plantarum and phytase,the present study aimed to evaluate the effects of cofermented DFRB on growth performance,antioxidant capacity,immune status,gut microbiota and permeability in finishing pigs.Ninety finishing pigs(85.30±0.97 kg)were randomly assigned to 3treatments(3 replicates/treatment)with a basal diet(Ctrl),a basal diet supplemented with 10% unfermented DFRB(UFR),and a basal diet supplemented with 10% fermented DFRB(FR)for 30 d.Results revealed that the diet supplemented with FR notably(P<0.05)improved the average daily gain(ADG),gain to feed ratio(G:F)and the digestibility of crude protein,amino acids and dietary fiber of finishing pigs compared with UFR.Additionally,FR supplementation significantly(P<0.05)increased total antioxidant capacity,the activities of superoxide dismutase and catalase,and decreased the content of malonaldehyde in serum.Furthermore,FR remarkably(P<0.05)increased serum levels of Ig G,antiinflammatory cytokines(IL-22 and IL-23)and reduced pro-inflammatory cytokines(TNF-α,IL-1β and INF-γ).The decrease of serum diamine oxidase activity and serum D-lactate content in the FR group(P<0.05)suggested an improvement in intestinal permeability.Supplementation of FR also elevated the content of acetate and butyrate in feces(P<0.05).Moreover,FR enhanced gut microbial richness and the abundance of fiber-degrading bacteria such as Clostridium butyricum and Lactobacillus amylovorus.Correlation analyses indicated dietary fiber in FR was associated with improvements in immune status,intestinal permeability and the level of butyrate-producing microbe C.butyricum,which was also verified by the in vitro fermentation analysis.These findings provided an experimental and theoretical basis for the application of fermented DFRB in finishing pigs. | Weifa Su Zipeng Jiang Cheng Wang Yu Zhang Tao Gong Fengqin Wang Mingliang Jin Yizhen Wang Zeqing Lu | 2022 | Animal Nutrition2022，，4： | 3 |

| 15 | Remote monitoring cost minimization for an unreliable sensor network with guaranteed network throughput显示文摘In this paper we consider a link-unreliable remote monitoring scenario where the monitoring center is geographically located far away from the region of the deployed sensor network,and sensing data by the sensors in the network will be transferred to the remote monitoring center through a third party telecommunication service.A cost associated with this service will be incurred,which will be determined by the number of gateways employed and the cumulative volume of data successfully received within a specified monitoring period.For this scenario,we first formulate a novel constrained optimization problem with an objective to minimize the service cost while a pre-defined network throughput is guaranteed.We refer to this problem as the throughput guaranteed service cost minimization problem and prove that it is NP-complete.We then propose a heuristic for it.The key ingredients of the heuristic include identifying gateways and finding an energy-efficient forest of routing trees rooted at the gateways.We also perform theoretical analysis on the solution obtained.Finally,we conduct experiments by simulations to evaluate the performance of the proposed algorithm.Experimental results demonstrate the proposed algorithm outperforms other algorithms in terms of both the service cost and the network lifetime. | Xu Xu Weifa Liang Zichuan Xu | 2014 | Information Processing in Agriculture2014，1，2： | 1 |

| 19 | Production of hispidin polyphenols from medicinal mushroom Sanghuangporus vaninii in submerged cultures显示文摘Objective: The medicinal mushroom Sanghuangporus vaninii produces pharmaceutically valuable hispidin polyphenols in natural habitats. However, due to the slow growth in nature, S. vaninii grown in the field(sclerotia) is not reliable for pharmaceutical purposes. Although higher biomass of fungal mycelia can be obtained in submerged cultures, the accumulation of hispidin polyphenols is rare.Methods: In this study, the polyunsaturated fatty acids(PUFAs), linoleic acid(LA), linolenic acid(ALA),and methyl jasmonate(Me Ja) were employed as the stimulant agents to coordinate the accumulation of biomass and hispidin polyphenols in its submerged cultures.Results: The addition of LA and ALA promoted the mycelial accumulation, while the addition of Me Ja inhibited the growth of S. vaninii concomitant with reduced total polyphenols. UPLC-Triple-TOF-MS analysis revealed an increased production of hispidin, phellinstatin, pinnilidine, and its derivatives upon the addition of LA and ALA, and hypholomine B and its isomer, 3,14’-bihispidinyl, and phelligridin E upon the addition of Me Ja on day 13. Intriguingly, total polyphenols from the Me Ja-supplementing cultures harbored a high capacity in scavenging free radicals. Chemical structural analysis showed that hispidin polyphenols had higher antioxidant activity due to more hispidin moieties induced by Me Ja.Conclusion: The supplement of PUFAs affects the synthesis and composition of hispidin polyphenols in S.vaninii. Our results provide a possibility to coordinate the production of hispidin polyphenols via submerged cultures of S. vaninii. | Wenwen Yuan Weihua Yuan Rong Zhou Guoying Lv Mengni Sun Yanxia Zhao Weifa Zheng | 2023 | Chinese Herbal Medicines2023，15，4： | 0 |
| 20 | Bacillus amyloliquefaciens 40 regulates piglet performance,antioxidant capacity,immune status and gut microbiota显示文摘Probiotics can improve animal growth performance and intestinal health.Bacillus species,Lactobacillus species,Bifidobacterium species,yeast etc.are the common types of probiotics.However,understanding the effects of probiotics on the immune status and gut microbiota of weaning piglets and how the probiotics exert their impact are still limited.This study aimed to investigate the effects of Bacillus amyloliquefaciens 40(BA40)on the performance,immune status and gut microbiota of piglets.A total of 12 litters of newborn piglets were randomly divided into 3 groups.Piglets in control group were orally dosed with phosphate buffered saline;BA40 group and probiotics group were orally gavaged with resuspension BA40 and a probiotics product,respectively.The results showed that BA40 treatment significantly decreased(P<0.05)the diarrhea incidence(from d 5 to 40),diamine oxidase,D-lactate,interleukin(IL)-1βand interferon-γconcentrations compared with control group and probiotics group.Meanwhile BA40 dramatically increased the total antioxidant capacity,IL-10 and secretory immunoglobulin-A concentrations in contrast to control group.For the microbial composition,BA40 modulated the microbiota by improving the abundance of Bacteroides,Phascolarctobacterium(producing short-chain fatty acids)and Desulfovibrio and reducing the proliferation of pathogens(Streptococcus,Tyzzerella,Vellionella and paraeggerthella).Meanwhile,a metabolic function prediction explained that carbohydrate metabolism and amino acid metabolism enriched in BA40 group in contrast to control group and probiotics group.For correlation analysis,the results demonstrated that BA40-enriched Phascolarctobacterium and Desulfovibrio provide insights into strategies for elevating the health status and performance of weaned piglets.Altogether,BA40 exerted stronger ability in decreasing diarrhea incidence and improved antioxidant activity,gut barrier function and immune status of piglets than the other treatments.Our study provided the experimental and theoretical basis for the application of BA40 in pig production. | Zipeng Jiang Weifa Su Wentao Li Chaoyue Wen Shuai Du Huan He Yu Zhang Tao Gong Xinxia Wang Yizhen Wang Mingliang Jin Zeqing Lu | 2023 | Animal Nutrition2023，，1： | 0 |
