Astaxanthin (ASX) is a xanthophyll pigment isolated from crustaceans and salmonids. Owing to its powerful antioxidant activity, ASX has been reported to have the potential to protect against gastric ulcers and a variety of other illnesses. Histamine (His) is a dietary factor that causes gastric erosion and ulceration in young chicks. In this study, we examined whether ASX had protective effects...

Inclusion body hepatitis (IBH) is a devastating disease of chickens caused by Fowl adenovirus (FAdV) and molecular studies hexon gene important for classification FAdV isolates, epidemiology IBH infection development effective control strategy. The objective the study was to molecularly characterize isolates obtained from field outbreaks in broiler chicken 2017 2019. Liver gizzard samples named...

Thirty-four fowl adenoviruses (FAdVs) isolated from chickens with gizzard erosion (GE) from 1999 to 2010 were characterized phylogenetically together with foreign isolates. The phylogenetic analysis based on part of the hexon gene classified these 34 FAdV isolates into 3 groups: FAdV-1, -8a and 8b, thereby suggesting that FAdVs associated with GEs in chickens are diverse. All 30 FAdV-1 isolates...

An experiment was conducted to investigate the effects of supplemental copper (Cu) chelates (methionine, chitosan and yeast) on the performance, nutrient digestibility, serum IgG level, gizzard erosion, Cu content in the liver and excreta and the level of total cholesterol in breast muscle and serum of broiler chickens. Two hundred and forty hatched broiler chickens (Ross 208) were assigned to ...
