The effects of electrolysed water (acidic or slightly acidic) on microbial load and physicochemical properties of chicken carcases were determined.

On d 1 and 7 post slaughter, samples were evaluated for physicochemical and microbiological characteristics. The pH, oxidation reduction potential (ORP) and available chlorine concentration (ACC) values of the solutions used in the application were determined.3. During storage, lipid oxidation remained stable in the samples treated with slightly acidic electrolysed water (p < 0.05). In addition, the application of acidic electrolysed water significantly (p < 0.05) decreased b* (yellowness) colour in the samples. Carcases in the A group had the lowest counts of total coliform bacteria, total mesophilic aerobic bacteria and S. aureus on d 1 (p < 0.05). Campylobacter counts in samples from group B significantly (p < 0.05) decreased during the storage period. The lowest E. coli count was detected in group A on both d 1 and 7 (p < 0.05). The reduction in Salmonella spp. counts during storage was similar in all groups.4. The results suggested that electrolysed water applications may be appropriate as an alternative to the chlorine dioxide solution used on the slaughter line in chicken slaughterhouses.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"633-639"},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143572192","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The eggshell weight of the UFG group was numerically reduced (p > 0.05) compared to the CFG and SFG groups. The papilla, barrier, effective layers and the thickness of the particular eggshell layers were different in each group. The amount of calcium (Ca) and phosphorus (P) in the bones, eggshells and excreta varied by group. According to gene expression analysis, PMCA and CaBP-28K expression in the duodenum and jejunum differed significantly4. The results suggested that segmented feeding may enhance Ca deposition in eggshells, reduce bone Ca loss and improve its utilisation efficiency.

This research explored the potential of hyperspectral imaging (HSI) to predict meat texture and the wooden breast (WB) condition in raw chicken breast fillets, categorised as normal, moderate WB and severe WB. The Meullenet-Owens Razor Shear (MORS) measurement was employed to characterise raw meat texture traits, including force, energy and peak count.2. Significant differences in MORS force, energy and peak count were observed between normal and severe WB fillets. However, no significant differences in these traits were found between normal and moderate WB fillets.3. Partial least square regression (PLSR) models, using the full wavelength range of visible and near-infrared (Vis-NIR) spectra, successfully predicted meat texture traits, with MORS peak counts exhibiting the highest predictive ability (Rp = 0.915 and RMSEp = 2.26). Key wavelengths were identified using the regression coefficient (RC) method, highlighting their significance in characterising meat texture.4. A linear discriminant analysis (LDA) model, incorporating all key wavelengths, achieved accurate predictions of WB severity, with 84.72% in the calibration set and 77.78% in the prediction set. This model demonstrated the potential of HSI in distinguishing WB fillets from normal ones, with an accuracy of 97.22%in the calibration set and 91.67% in the prediction set.

Faecal microbiota transplantation (FMT) is a technique that promotes gut microbiota diversity and abundance by transplantation of faeces into a recipient's gastrointestinal tract via multiple routes.2.

Inulin can inhibit pathogenic bacterial growth by lowering pH, promote mineral absorption and improve intestinal barrier integrity.3. In this study 90 one-day-old chicks were randomly into three groups; control (CON) group was fed a basic diet; FMT group fed two diets containing 40 ml faecal microbial suspension; and INU group fed a diet containing 1.5% inulin and 40 ml faecal microbial suspension.4. Administering the FMT mixed with inulin effectively reduced blood levels of IL-1β, IL-4 and IL-6, promoted the growth of thymus, bursa of Fabricius and spleen. In addition, it enhanced intestinal barrier function, increased intestinal goblet cells and Paneth cells production, promoted probiotic colonisation and butyrate formation and reduced intestinal inflammation.5.

Chicken ghrelin (GH) plays an important role in regulating growth hormone secretion, immunity and gastrointestinal motility. This study utilised haematoxylin-eosin staining, quantitative reverse transcription PCR and western blotting to examine the effects of high-level ghrelin on the proliferation of small intestinal epithelial cells, intestinal nutrient transport and the mucosal immune barrier in chicks.2. Eighty, 17-d-old layer type chicks were randomly divided into two groups: control (C treated with sterile phosphate buffer) and the ghrelin-treated group (GH; intraperitoneally injected with 0.5 nM GH per 100 g body weight). At 1, 3 and 5 d post-injection, six chicks from each group were randomly selected for sampling of the duodenum and ileum.3. Administering GH reduced the expression of proliferating cell nuclear antigen protein in the duodenum and leucine-rich repeat-containing G protein-coupled receptor 5 mRNA in both the duodenum and ileum. In addition, GH affected villus height and ratio of villus height to crypt (H/C) depth in these sections and fatty acid binding protein 6 expression in the ileum. The relative mRNA levels of oligopeptide transporter 1, solute carrier family 3 member 1, solute carrier family 1 member 1 and solute carrier family 5 member 1 were decreased by GH.4. Birds treated with GH had a decrease in duodenal intraepithelial lymphocytes, Paneth cells and ileal goblet cells. There was a reduction in mucin 2 mRNA in goblet cells and lysozyme C and phospholipaseA2 mRNA in Paneth cells. Additionally, the relative mRNA levels of avian β-defensin 1 (AvBD1), AvBD6 and AvBD7 in the duodenum and ileum decreased with GH administration.5. The GH inhibited proliferation of chicken duodenal epithelial cells and decreased surface area available for intestinal villus absorption. This affected the transport of intestinal amino acids, glucose and bile acids and impaired the function of the mucosal immune barrier in both the duodenum and ileum.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"656-671"},"PeriodicalIF":1.7,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143673383","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study employed an automated estimation method for quantitatively assessing valuable meat parts in broiler chickens. This involved the segmentation of computed tomography (CT) images through elastic registration, utilising feature and model selection.2. Sixty Tetra HB colour broiler chickens (30 males and 30 females) were randomly selected and examined by CT at 10 weeks of age (live weight: 2560 ± 400 g). The animals were slaughtered, and their breast and thigh muscles were dissected and weighed (thigh and breast weights were 90 ± 19 g and 337 ± 58 g). Multi-atlas registration was used for segmentation, followed by feature extraction (256 features/individual) from the CT images.3. Four different regression analysis techniques (linear, PLS, lasso and ridge) with and without feature selection were applied to the collected data with k-fold cross-validation for estimating the thigh and breast muscle weights. The feature selection produced significantly better results in all cases.4. Among the analysis techniques, lasso and ridge regression performed the best for both muscle groups (thigh and breast muscles). These were as follows: lasso for breast: r2 = 0.993, RMSE = 4.87 g; ridge for breast: r2 = 0.995, RMSE = 4.03 g; lasso for thigh: r2 = 0.976, RMSE = 2.94 g; and ridge for thigh: r2 = 0.965, RMSE = 3.53 g.5. The results demonstrated the effectiveness of the automated method, initially tested on rabbits, in accurately estimating valuable meat parts of broiler chickens.

Liver-enriched antimicrobial peptide 2 (LEAP2), ghrelin and growth hormone secretagogue receptor (GHSR) are critical components of the appetite regulation system. This study analysed changes in LEAP2-ghrelin-GHSR expression across diverse feeding conditions and body weights in adult broilers and investigated the effects of intraperitoneally injected LEAP2 and ghrelin peptides on the feed intake of chicks.2. In adult broilers, the expression of LEAP2 in the liver and intestine exhibited significant variations under different feeding conditions (fed, fasting and refeeding), with a notable reduction observed during fasting. Compared to the fed group, proventriculus ghrelin and hypothalamus GHSR gene expression doubled, but was not statistically significant. Serum analyses revealed that fasting significantly decreased LEAP2 levels relative to the fed state and a significant negative correlation was identified between LEAP2 levels and body weight in fasting chickens. Conversely, ghrelin levels remained stable irrespective of feeding states and showed no correlation with body weight.3. Intraperitoneal injection of LEAP2 mature peptide, comprising the N-terminal 14 amino acids significantly reduced feed intake of chicks within the initial 4 h. In contrast, ghrelin injection resulted in a decrease in feed intake during the first 30 min. However, prior administration of ghrelin followed by LEAP2 mitigated the suppressive effect of ghrelin on feed intake within this timeframe.4. This study demonstrated that chicken LEAP2 gives a more sensitive feedback factor than ghrelin under different feeding conditions in adult broilers. It revealed that LEAP2 in a chick model modulated feed intake. These findings provide a theoretical basis for exploring the underlying mechanisms of LEAP2-mediated feed intake regulation in poultry.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"1-8"},"PeriodicalIF":1.7,"publicationDate":"2025-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145130015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
