Optimizing Cassava Starch Residue Inclusion in Broiler Diets: Balancing Growth Performance, Liver Health and Gut Microbial Dynamics

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Moderate inclusion (20–30%) of cassava starch residue in broiler diets improved gut morphology and reduced E. coli counts with minimal adverse effects, while higher levels impaired growth and liver health. The findings highlight CSR's potential as a partial maize replacement, but caution is needed at elevated inclusion rates.

The evolutionary landscape and serotypic dynamics of avian infectious bronchitis virus from spike protein

iMetaOmics, Volume 3, Issue 1, March 2026.
This study integrates two decades of surveillance with genomic and structural analyses to decipher how spike protein glycosylation haplotypes drive avian coronavirus evolution. We uncover how specific glycosylation patterns associate with receptor‐binding affinity, shape global transmission dynamics, and correlate with clinical outcomes.

Histomorphology of bursa of Fabricius: effects of stock densities on commercial broilers

Brazilian Journal of Poultry Science, 2006
During the past few years, there has been considerable interest on the effects of stocking density on broiler behavior and immunity. Stress may cause immunodeficiency by affecting cell and humoral responses, as well as body weight decrease, and foot-pad ...

Bridging the gap: improving methodologies for future avian microbiome research

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Recent advances in the field of wild avian microbiome research have significantly deepened our understanding of the eco‐evolutionary dynamics of bird–microbe interactions. Consequently, the field is now approaching a pivotal moment in uncovering the ultimate factors shaping avian microbiome structure, especially in relation to birds' ecological ...

Effect of Probiotic and Synbiotic Supplementation on Growth Performance, Serum Parameters and Gut Histomorphometry in Broiler Chickens Challenged With Eimeria

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
This study assessed probiotic and synbiotic supplementation via drinking water in Eimeria challenged broilers. In a 2×3 factorial design with 360 Cobb 500 chickens, Eimeria impaired growth, FCR and gut morphology, while probiotics and synbiotics improved performance, intestinal structure and serum biochemistry, alleviating coccidiosis induced damage ...

The Bursa of Fabricius and Homograft Immunity

Poultry Science, 1965
Abstract Hieronymus Fabricius (1621) reported the existence of a sac in the podex of the hen which he believed served as a semen receptable. (Apparently he didn’t notice its presence in cocks). Named the Bursa of Fabricius in his honour, the function of this organ was unknown until the discovery of its role in antibody production by a remarkable ...
