A case from 32 days old broiler with swollen and fatty liver, swollen kidney and hydropericardium alone with this lesion. Daily mortality 12-15 birds (fz: 3500) and in increasing rate.Please suggest the dx & Rx?
Shiva BhusalI IBH mainly affect chicks at 2-3 wks with main lesion mainly in liver and somewhat kidney with out effect on proventericulus and gizzard but adenovirus can affect proventericulus and gizzard and lead to gizzard errosin
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
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.
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?
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.
