The aim of the trial was to compare the efficacy of immersion-based crate washing systems with a spray-based washing system in reducing Campylobacter spp. Therefore, the crate washing systems in two slaughterhouses were sampled. In one of these two slaughterhouses, the immersion-based crate washing system was replaced by a new spray-based system which was sampled. Samples were collected from the slaughterhouse equipment, the crate washing system as well as from the crates both before and after cleaning and disinfection (C&D). All samples were screened for the presence of Campylobacter spp.; water and crate samples were used for enumeration. Molecular typing was performed to investigate the source and routes of contamination.3. In all cases, crates were contaminated with Campylobacter spp. prior to washing. However, only the spray-based system achieved a significant reduction after C&D Molecular typing revealed that the same strains were present on the crates after C&D as before cleaning. Additionally, crates could become contaminated by previously cleaned crates via wash water in the immersion-based crate washing system.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"358-366"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142930672","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}

Six pelleted diets with different ratios of whole oats to dehulled oats, ground either finely (2 mm) or coarsely (6 mm), resulting in 0.05% (LOH), 6.5% (MOH) and 11.4% (HOH) OH inclusion, were fed to broilers to study gizzard functionality and its influence on passage of large oat hull (OH) particles. The hypothesis was that coarse OH would be selectively retained in gizzard for grinding, but higher levels would increasingly result in passage of unground OH.2. In experiment 1, gizzard and small intestinal contents were sampled from 78 birds at 28-29 d of age. Neutral detergent fibre (NDF) of gizzard contents was over three times higher than that of diets, indicating selective retention. An interaction effect of OH and screen size was seen for large particles (>1.6 mm) in the upper ileum, which was higher for MOH and HOH than LOH and only for coarse diets. This indicated that passage of unground coarse large particles from the gizzard increased when it exceeded a maximum retention level.3. In experiment 2, pre-weighed amount of HOH 2 mm and HOH 6 mm diets were fed to 80 birds for 2 h and were sampled on d 30 at 0, 2, 4, 8 and16 h to study OH degradation and flow. Contents were sampled from the crop, gizzard, small intestine, colon/cloaca and excreta. Unrecovered NDF in gastrointestinal tract plus excreta increased with more time and coarseness. An interaction effect between time and screen size was found for large particles in excreta, which was higher for 6 mm diets than 2 mm diets at 16 h.4. The presence of large OH particles in excreta challenged the previous assumption that particles are ground in the gizzard to a certain critical size before passing down further down the digestive tract. Some OH seemed to escape grinding in gizzard and this was higher for coarser particles.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"391-400"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142709316","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}

It remains unclear whether slow-growing broilers actually represent an overall animal welfare improvement - a major knowledge gap for policymakers and animal welfare NGOs. This paper addresses this knowledge gap by using an economic model to produce an all-things-considered estimate of the welfare effects of slow-growing genotypes. A quantitative end-point welfare metric that accounts for welfare challenges throughout the production cycle used the Pain-Track method from the Cumulative Pain Framework.2. Longer lifespans of slow-growing broilers (relative to fast-growing broilers) typically caused an increase in the time spent in low-intensity negative affective states. However, despite the additional broilers being farmed and their longer growth period, switching to slow-growing genotypes caused a decrease in higher-intensity negative affective states - a major win for welfare.3. These results can be used to alleviate consumer and producer concerns that any transition causes a welfare risk and provide an optimistic understanding of the overall welfare impact of transitioning to slow-growing broilers.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"290-298"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142930675","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 evaluated the impact of nanoemulsion coating solutions, comprising chia mucilage and different concentrations of sage essential oil (SEO) on antioxidant properties and quality characteristics of turkey breast during storage using VI.2. Five coating solutions were developed, including coating with water (CV), chia mucilage (CMV), chia mucilage + 0.5% SEO (CMS1V), chia mucilage + 1% SEO (CMS2V) and chia mucilage + 1.5% SEO (CMS3V).3. The results indicated that increasing the SEO in nanoemulsion solutions significantly boosted antioxidant activity. Incorporating sage essential oil at a concentration of 1.5%, led to a notable reduction in peroxide value (PV) and thiobarbituric acid reactive substances (TBARS), which suggested reduced lipid oxidation. Additionally, the carbonyl and sulphhydryl content of turkey strips were significantly influenced by nanoemulsion coating solutions. Microbiological analysis revealed that nanoemulsions containing chia mucilage + SEO effectively reduced microbial load during storage, highlighting the antimicrobial properties of SEO. Furthermore, nanoemulsion coatings containing SEO inhibited the increase in total volatile basic nitrogen (TVB-N) values during storage, which extended the freshness of the meat.4.

The remaining isolates from other Salmonella spp. serotypes (n = 84) and bacterial species (n = 8) were negative in both LAMP assays.3. The methods detected DNAs from S. Enteritidis and S. Heidelberg after a single-step pre-enrichment in buffered peptone water of the poultry samples, which agreed with previously developed PCR methods to detect these same two serotypes.4. In conclusion, LAMP assays were useful for rapid serotype-specific detection, being suitable for surveillance purposes in resource-limited environments such as poultry farms.","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"367-373"},"PeriodicalIF":1.6,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142615189","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}
