A total of 192 samples were collected from three different poultry farms and slaughterhouses and <i>C. jejuni</i> was detected in 47.4% of them. The prevalence of <i>C. jejuni</i> was higher in poultry slaughterhouses than in farms. A total of 69 <i>C. jejuni</i> were tested for their susceptibility to different antibiotics. From these 15 isolates from poultry farms and slaughterhouses, 50-70% exhibited antibiotic resistance.

Nearly all <i>C. jejuni</i> isolates harboured plasmid sizes ranging from 2.3 to 23 kb. The virB11 gene of <i>C. jejuni</i> was characterised using PCR and there was no gene amplification in the isolated strains. All multidrug-resistant (MDR) isolates from poultry farms and slaughterhouses had full-length lipo-oligosaccharide molecules, based on their molecular weight.4.

The poultry sector is possibly the fastest growing and most flexible of all livestock sectors. At present, the main changes to the table egg production system include the gradual abandonment and closure of all cage-housing systems for laying hens, driven by animal welfare concerns and stricter legislation in many countries. In the future, keeping hens in enriched cage systems may be restricted or phased out in response to evolving animal welfare guidelines and public demand. To meet the welfare and behavioural requirements of the hens, it is desirable to choose housing on litter or housing in aviaries as a substitute for housing in enriched cages.2. The objective of this systematic review was to examine non-cage housing systems and hemp-based dietary interventions in relation to skeletal health in laying hens. This review focussed on the risks associated with alternative housing systems, particularly the increased incidence of bone fractures and the potential of nutritional strategies to mitigate skeletal disorders, including osteoporosis.3. The proportion of hens housed in non-cage alternative housing systems is currently increasing sharply but carries certain risks. One of the most significant concerns is skeletal integrity, as hens in aviaries experience a higher rate of keel bone fractures due to collisions, falls and deviations thought to be related to internal pressure. Numerous studies have shown that the incidence of keel bone damage (<i>i.e</i>. fractures and deviations) was greater in aviaries compared to enriched cage systems.4. Optimal skeletal health can be supported through proper nutrition, which plays a crucial role in bone metabolism. Key nutritional elements, including calcium, vitamins D, E and K, polyunsaturated fatty acids and hemp-based products, have been shown to be beneficial in preventing skeletal disorders and associated fractures due to their specific roles in maintaining bone structure and strength.</p>","PeriodicalId":9322,"journal":{"name":"British Poultry Science","volume":" ","pages":"1-30"},"PeriodicalIF":1.6,"publicationDate":"2025-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143975864","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}

A formulation was developed to induce spontaneous biofilm formation of probiotic bacteria (BV, BS and LL) by testing various media containing minerals and polymers on polystyrene plates. The most potent probiotic strains were identified based on their efficacy in inhibiting SH and APEC. The formulation was tested on wood shavings to hinder APEC and SH. The safety and colonisation of the formulation was assessed in chicken embryos (CE) from 19 d of incubation to the broiler chicken stage.3. After evaluating various media, one containing calcium, magnesium, iron and polymers (dextran, chitosan and xylan) was selected. Notably, xylan, a highly sustainable biopolymer, showed outstanding results at a low concentration (27 µg/ml), which led to its selection for conducting inhibition tests on wood shavings against SH and APEC. The <i>B. velezensis</i> demonstrated superior biofilm formation and efficacy in controlling SH and APEC. Consequently, a BV strain was selected and associated with a strain of LL.4.
