Gizzard and proventiculus

May be severe mycotoxins

Check crop and proventriculus for any fungal growth. Because it may happen in case of candidiasis. Provide the birds with Acidified Copper sulphate@1g/2 litre of water and Magnesium Sulphate @ 1g/litre of water for three days

bad pellet quality and feed toxicity

Hydropericardium rings of Adeno virus involvement.

This is the challenge I have faced many time with experienced of Mycotoxicosis with Adenoviral infection IBH also related to kidney swollen but liver liver is mottled with enlargement

Proventriculitis could be the causes virus eg. Reo adeno, IBD, IB virus. could be bacterial origin eg. clostridium or other causes as biogenic amines,copper sulfate toxicity and mycotoxicosis.

Might be due to adenoviral and or Reoviral involvement if you are getting similar findings in all other birds

Hi everybody, in this case I see enlarged of proventriculus with feed and shrunked gizzards which are empty. May I ask firstly, do you make fasting program, and do you use fine feed or bad pellet quality ? If both no, we can focus other factors such as mycotoxine and especially Adeno virus.

There are probably several factors. 2 main culprits: 1) infectiuous "proventriculitis" caused by a mix of more or less identifieed virus and bacteria 2) good pellet quality made of very fine mash. That means high feed intake but very poor control of the feed flow in the upper gut and no development of the gizzard muscle. This has probably an effect on the dilatation isthm section. This factor is easier to fix than preventing early chick contamination, especially in deep litter production systems.

Hi Guys, Anybody else has experienced biogenic amines causing proventriculus to become flaccid or enlarged? There is also a similar Proventricular Dialation disease caused by Avian Bornavirus? How is the Biosecurity of the sheds? https://wildlifehealthaustralia.com.au/Portals/0/Documents/FactSheets/Avian/Avian%20Bornavirus%20and%20Proventicular%20Dilatation%20Disease%20Nov%202013%20(2.3).pdf

Yes

I have seen such cases , in Pune region during 2007-2009 period with enlarged proventriculus and gizzard erosions. In your case it is 100% HPS and IBH based on lesions mentioned by you. It is better to find another source of chicks who’s parents got vaccinated with Adenovirus Serotype 4,8a 8b. Adenovirus mainly passed thru feces so take care to treat birds with virucidal agents in D/W and don’t put burden on liver instead give high energy feed , liver supplements like Liv-52 is absolutely perfect. Wish you best luck

I strong recommend use the sieve #5 to grind the corn and produced pellet 3.2mm or 4 mmm it will solve all the problems regarding the issue plus improve the feed conversion. Please study gelatinização before any argumentation about my comments. Plus your personal experience regarding what I am trying to share to improve your operations performance.

It may be a case of IBH .In this specific case a significant decrease in feed offering along with feed dilution with wheat bran is very effective.
