Highly Variable Microbiota Development in the Chicken Gastrointestinal Tract
Published:September 8, 2017
Summary
Introduction A range of studies have investigated the structure of the microbiome in the gut of broiler chickens. Comparison across studies has proven difficult because of the variety of different methods used; e.g. culture based studies [1], G+C profiling analysis [2], quantitative PCR [3], and 16S rRNA based studies. The 16S-based methods have used a number of different approaches including ...
Interesting work presented, congratulations. My question then is from which day should we try to influence microbiota in birds - by feeding certain probiotics - and for how long? Yet, how do we influence the microbiota by increasing digestibility of feeds? Many thanks from Madrid, Rafa.
Rafael Duran, thanks for your interest and questions. My belief is that we need to provide probiotics no later than point of hatch, or earlier if feasible, in order to influence the development of the gut microbiota. Once this is set it is difficult, if not impossible, to alter it without continuous application of probiotics. How long to provide probiotics after hatch is difficult to say due to lack of suitable published evidence in this area. This is a topic requiring much more research effort in my view.
A/Prof Bob Hughes hi dr
Can u brief us that by providing probiotoc either required daily on regular feeding or some ratio for enhancement and which one is the best probiotic on yr research
fazal Malik Malik As I said earlier, "How long to provide probiotics after hatch is difficult to say due to lack of suitable published evidence in this area. This is a topic requiring much more research effort in my view." Which probiotics are effective is also difficult to say based on published data. As in the early days of exogenous feed enzyme usage there were many claims and also many failures. Marketing hype outpaced validation by repeatable and independent research findings back then as it does now.
Interesting article for gut health because nowadays most research is done on how to regulate the beneficial bacteria in the gut system. Sir, what is your opinion about organic acids instead of probiotics? Can acidifiers affect the gut microflora during early age? If we add OA acids during starter and finisher, which will be the form to regulate the gut microbiota?
Pirzado M Zakria I have no direct experience with organic acids or acidifiers hence have no informed opinion. I advise you to look for well written, peer-reviewed articles to answer your questions.
Pirzado M Zakria my brother in ruminants oA have good response but in mono gastric required trials any body hw have taken trials kindly he can brief us
