The Poultry Hub team thought, given the rise in both public engagement around how we farm and the huge increases in so- cial media, it was time to provide the industry and our researchers an oppor- tunity to tell their story.
Excreta of the individ- ual birds were collected and assessed for specific biomarkers using chick- en-specific enzyme-linked immunosorbent assays.
Ideally, such tests can be completed in less than a day and can indeed help industry to reduce costs associated with enteric diseases.
The key question asked by journalists is: “So, what’s your story?”
I would like to share this story, written by Reza Barekatain, highlighting the great achievements he has made in his recently completed PHA funded project ‘Identifying non- invasive biomarkers of in- testinal permeability and inflammation in broiler chickens’.
In poultry, most cur- rently available methods require bleeding or eu- thanising the animals, which are invasive and not beneficial on farm.
These need to be further validated in larger scale trials including samples from group-housed ani- mals.
Further, if the identified biomarkers are found re- sponsive to certain feed additives, this can facili- tate effective in-feed in- terventions to minimise the impact of gut health issues.”
Participants learnt that they, as the person being asked the question, hold all the power in the relation- ship, and are known in the business as the ‘talent’.
Hence, we identified the need to determine bio- markers with which the intestinal integrity is as- sessed rapidly and in a non-invasive manner.
Once validated and commercial kits made available at an afforda- ble price, the assays could provide a relatively rapid method to detect proteins that are either elevated

Television channel and newspaper journalists generally want a second voice, so participants were asked to think about who could play the supporting character in their story, and to make sure they were available.
“A healthy gut has al- ways been essential for good well-being.
A Poultry Hub Australia supported project, led by Dr Reza Barekatain at the South Australian Re- search and Development Institute in collaboration with Feedworks and Uni- versity of Adelaide, spe- cifically sought to identify selected proteins in excre- ta of chickens as biomark- ers of intestinal perme- ability and inflammation, as a non-invasive method to assess gut integrity.

Enterocytesareintestinal cells that form a physical barrier to prevent harm- ful bacteria and unwanted materials from entry into the gut, and also allow nu- trient absorption.
Most previous studies have focused primarily on necrotic enteritis models and sampling the intesti- nal contents.
Hosted by Poultry Hub, with the support of Aus- tralian Eggs and AgriFu- tures, the forum provided the opportunity for re- searchers, industry mem- bers and Australian busi- nesses to be introduced to the media.
When there is a ‘dys- functional gut barrier’, there is a chance of bac- terial translocation from the intestine into internal organs, often causing in- testinal inflammation and impaired performance.
In this study, we sub- jected meat chickens to two different ‘leaky gut’ (gut barrier dysfunction) models based on a stress- inducing factor (dexa- methasone as synthetic

We found proteins, in- cluding fibronectin, al- kaline phosphatase and lipocalin 2, in the excreta were responsive to the in- testinal barrier dysfunc- tion models tested in the study.
Meanwhile, the iden- tification of additional biomarkers of gut health and real-time detection devices remain an active area of research.
These were a few of the tips and pointers that came up in conversation with the three journal- ists who took part in the online ‘Meet the Media’ forum held on Tuesday September 22.
Even 2500 years ago, Hippocrates said: “All disease begins in the gut” – and poultry are no dif- ferent.
Gut integrity sits at the core of gut health re- search to support health and growth in poultry.
