Genetic and Biological Characteristics of Gruid Herpesvirus 1 Isolated From Wild Cranes Affected by Inclusion Body Disease of Cranes

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Inclusion body disease of cranes (IBDCs) is fatal in many cases and reportedly caused by a herpes‐like virus labeled as gruid herpesvirus 1 (GrHV‐1). Although GrHV‐1 has been isolated from IBDC‐affected cranes, it has not been genetically classified because its genome has not been partially or fully sequenced.

Optimising Growth, Immunity, and Gene Expression in Broiler Chickens Through Dietary Threonine Levels and Oil Inclusion

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
This research investigated the impact of varying threonine levels and dietary oil content on broiler chickens' growth and immunity. The results showed that combining high oil with a threonine level of 115% led to optimal outcomes for the birds. This combination improved growth performance, immune parameters, intestinal health, and gene expression ...

THE STRUCTURE OF THE BURSA OF FABRICIUS IN WILD BIRDS

The Keio Journal of Medicine, 1971
The bursa of Fabricius of wild birds, especially that of Passerine birds was investigated, and it was established that there are two types of structures in the mucous membrane, i.e., the plica type and the tubulus type. The development and structure of the lymph follicle in each type were discussed.

Effects of High‐Fructose Corn Syrup Addition to Broiler Diets on Performance, Carcass Yield, Visceral Weights, Gut pH and Some Blood Parameters

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
The addition of 100 mg/kg high fructose corn syrup (HFCS) to broiler diets negatively affected performance parameters, but HFCS supplementation positively affected biochemical parameters. HFCS could be added to broiler diets at a level of 50 mg/kg. ABSTRACT Background This study hypothesizes that using different amounts of high‐fructose corn syrup ...
