Iron deficiency anemia (IDA) is a nutritional deficiency disease with a high incidence rate worldwide. Bioactive peptides are safe and effective， have multiple functions and can serve as potential candidates for alleviating IDA. In this study， the anti-anemia effects of tuna dark muscle peptides were explored in a diet-induced IDA mouse model. The results showed that tuna dark muscle peptides alleviated the IDA phenotype， oxidative stress and iron metabolism. In addition， tuna dark muscle peptides reversed gut microbiota dysbiosis in IDA mice. Furthermore， the transplanted fecal microbiota from tuna dark muscle peptide-treated mice also alleviated IDA symptoms and regulated iron metabolism and the gut microbiota， indicating that the anti-anemic effects were at least partially mediated by the gut microbiota. Thus， we identified a new and safe prebiotic material to alleviate IDA and provided ideas for the development of peptides. At the same time， these data also provided a theoretical basis for fecal microbiota transplantation (FMT) to alleviate IDA.

Background:Intrauterine growth restriction(IUGR)has negative impacts on the postnatal survival,growth and development of humans and animals,with not only on newborns but also adulthood.However,the characteristics for nutrient digestion and absorption in IUGR offspring are still largely unknown.Therefore,the normal birth weight(NBW)and IUGR growing pigs were used in this study to investigate their differences in nutrient utilization,with an expectition for further nutritional optimization of the IUGR offspring during their later life.Methods:Twelve IUGR and 12 NBW growing pigs were fitted with catheters in their portal vein to measure blood flow rate as well as nutrients and metabolites in plasma.The digestibilities of nutrients in different intestinal segments,and bacterial fermentation in the large intestine were examined to reveal the characteristics of nutrients utilization in IUGR versus NBW pigs.Results:The rate of portal venous blood flow did not differ beween IUGR and NBW pigs.Plasma concentrations of total cholesterol,triglycerides and glucose were much lower but those of urea were higher in the portal vein of IUGR pigs,compared with the NBW pigs.The ileal digestibility of dry matter,gross energy and starch were lower in IUGR pigs than in NBW pigs.IUGR increased hindgut microbial diversity and bacterial fermentation activity in the caecum.In vitro cross-fermentation of ileal digesta by caecal microbes of NBW and IUGR pigs showed that gas production was much higher for IUGR ileal digesta regardless of the source of caecal inocula.Conclusion:IUGR impairs the nutrient digestion and absorption in small intestine,reduces caecal microbial diversity and promotes bacterial fermentation in the large intestine during the growing phase.These findings aid in our understanding of nutrient metabolism in IUGR pigs and provide the basis for future nutritional interventions.

Background:The application of fecal microbiota transplantation(FMT)to improve swine growth performance has been sporadically studied.Most of these studies used a single microbiota source and thus the effect of donor characteristics on recipient pigs’fecal microbiota development and growth performance is largely unknown.Results:In this study,we collected feces from six donors with heavy(H)or light(L)body weight and different ages(d 42,nursery;d 96,growing;and d 170,finisher)to evaluate their effects on the growth performance and fecal microbiota development of recipient pigs.Generally,recipients that received two doses of FMT from nursery and finisher stages donor at weaning(21±2 days of age)inherited the donor’s growth pattern,while the pigs gavaged with grower stage material exerted a numerically greater weight gain than the control pigs regardless of donor BW.FMT from heavier donors(NH,GH,and FH)led to the recipients to have numerically increased growth compared to their lighter counterparts(NL,GL,and FL,respectively)throughout the growing and most finishing stages.This benefit could be attributed to the enrichment of ASV25 Faecalibacterium,ASV61 Faecalibacterium,ASV438 Coriobacteriaceae_unclassified,ASV144 Bulleidia,and ASV129 Oribacterium and decrease of ASV13 Escherichia during nursery stage.Fecal microbiota transplantation from growing and finishing donors influenced the microbial community significantly in recipient pigs during the nursery stage.FMT of older donors’gut microbiota expedited recipients’microbiota maturity on d 35 and 49,indicated by increased estimated microbiota ages.The ageassociated bacterial taxa included ASV206 Ruminococcaceae,ASV211 Butyrivibrio,ASV416 Bacteroides,ASV2 Streptococcus,and ASV291 Veillonellaceae.The body weight differences between GL and GH pigs on d 104 were associated with the increased synthesis of the essential amino acid,lysine and methionine,mixed acid fermentation,expedited glycolysis,and sucrose/galactose degradation.Conclusions:Overall,our study provided insights

In this work,we interpreted gravity data to determine the structural characteristics responsible for high-gravity anomalies in Bagodo,North Cameroon.These anomalies had not previously been characterized through a local study.Thus,we undertook a regional-residual separation of the gravity anomalies by using the polynomial method.Geophysical signatures of near-surface small-extent geological structures were revealed.To conduct a quantitative interpretation of the gravity anomalies,one profile was drawn on a residual Bouguer anomaly map and then interpreted by spectral analysis,the ideal body solution,and 2.5-dimensional modeling.Our results showed that the intrusive body in the Bagodo area consists of two trapezoidal blocks.The first and second blocks have roofs approximately 7.5 and 14 km deep,respectively,whereas their bases are approximately 17 km deep.These values are in agreement with those obtained by the ideal body solution,which showed two cells with a density contrast of 0.3 g·cm^(−3) in comparison with the surrounding rocks.The density of this body was estimated to be approximately 3 g·cm^(−3).The topography of these rocks showed that they are basaltic rocks that would have cooled in fracture zones as an intrusion.

There are many different production situations that can be employed to meet demand. In the engineer-to- order （ETO） production situation, products are manufac- tured to meet specific customer needs by unique engineering or significant customization. In such an environment, failing to supply the required materials in the right quantities and at the right time increases the risk of breaching due date agreements and thereby losing customer satisfaction. As such, materials management is one of the most important and critical processes within production planning and control in ETO. To bring attention and improvement to this area, ETO companies may benefit from a performance measurement system （PMS） that systematically monitors how well mate- rials management is carried out. The design of a company＇s PMS varies with its production situation. Within the large body of literature on performance management and mea- surement, limited literature specifically addressing perfor- mance measurement in ETO has been identified. After being approached by a Norwegian ETO company requesting a PMS for materials management, the authors therefore set out to design the PMS from scratch, using literature on ETO, materials management and performance management and measurement as a starting point. The paper presents the proposed PMS. It provides a basis for further studies on the topic, and could be used by managers in ETO companies to assess and improve their materials management practice.

Background:Intestinal microbiota plays a key role in nutrient digestion and utilization with a profound impact on feed efficiency of livestock animals.However,the intestinal microbes that are critically involved in feed efficiency remain elusive.Methods:To identify intestinal bacteria associated with residual feed intake(RFI)in chickens,male Cobb broiler chicks were individually housed from day 14 to day 35.Individual RFI values were calculated for 56 chickens.Luminal contents were collected from the ileum,cecum,and cloaca of each animal on day 35.Bacterial DNA was isolated and subjected to 16S rRNA gene sequencing.Intestinal microbiota was classified to the feature level using Deblur and QIIME 2.High and low RFI groups were formed by selecting 15 and 17 chickens with the most extreme RFI values for subsequent LEfSe comparison of the difference in the microbiota.Spearman correlation analysis was further performed to identify correlations between the intestinal microbiota composition and RFI.Results:No significant difference in evenness,richness,and overall diversity of the microbiota in the ileum,cecum,or cloaca was observed between high and low RFI chickens.However,LEfSe analysis revealed a number of bacterial features being differentially enriched in either high or low RFI chickens.Spearman correlation analysis further identified many differentially enriched bacterial features to be significantly correlated with RFI(P<0.05).Importantly,not all short-chain fatty acid(SCFA)producers showed a positive association with RFI.While two novel members of Oscillibacter and Butyricicoccus were more abundant in low-RFI,high-efficiency chickens,several other SCFA producers such as Subdoligranulum variabile and two related Peptostreptococcaceae members were negatively associated with feed efficiency.Moreover,a few closely-related Lachnospiraceae family members showed a positive correlation with feed efficiency,while others of the same family displayed an opposite relationship.Conclusions:Our results highlight the complexity
