Looking at the droppings there would appear to be a relatively low incidence of diarrhoea (2 only). In some systems, where there are a lot of flies and the faeces are stored under the pens (e.g. deep pits) higher incidences say up to 30-40% of droppings can be affected which definitely reduces egg production and increases mortality. Where the faeces are cleared away by belt (as in the picture?) th ...

Presumably they were using individual pig body weights on day 42 to get their statistical results, and hence ADG was not significant if done on a pen average basis, as you suggest. Interestingly, from a veterinary perspective, the diarrhoea was occurring 4-6 weeks after weaning and not the usual 1-2 weeks after weaning (normal post-weaning diarrhoea period associated with E. coli). Were other bact ...

Caecal droppings (yellow pasty mucoid droppings) in layers can be very common, caused by Brachyspira infections. We found them to be present in most free-range flocks, causing 20% drop in production and an additional 10% mortality if untreated. In cage sheds, flies seemed to be important in the transmission of the infection - faeces - flies - feed - and in many tropical countries they have open-si ...

Tarusenga Munyanyi Back in the 2000s we had a lot of problems with mucoid yellow droppings particularly in free-range flocks. We carried out a survey on a large number of farms and found that these problems were primarily associated with Brachyspira species infections, B. pilosicoli, B. intermedia and B. innocens. See http://www.octagon-services.co.uk/poultry.htm enteric diseases section there are ...

Sorry for delay been away on holiday. Yes it has been found in turkeys aged 7.5-18 weeks old. There is a potential risk but I must admit that I have not seen it in the UK. It could be due to the use of anti-coccidials in turkeys in the UK such as monensin and lasalocid in growing turkeys. In Philippines, growing chickens were kept on wire and I am not sure how their turkeys were reared. Regards Da ...

It is difficult to diagnose as the Brachyspira only survive in faeces for 24 hours. This is the reason PCR was so helpful. Normally id enough samples are submitted they will pick it up. Murdoch University in Perth Australia is particularly good at it. Usually we do not treat unless 20% of birds are showing the frothy diarrhoea, when it gets to 40% you can see a marked reduction in performance of ...

Dear Ismet, avian intestinal spirochaetosis is spread worldwide in both layers and breeders. The isolation of Brachyspira is quite difficult but PCR techniques are available to determine the presence and the species. Most flocks by the age of 40 weeks will be positive. Certain strains B. pilosicoli and B. intermedia are the common pathogenic ones and usually the condition is associated with the in ...
