The Effect of Clay‐ and Yeast‐Based Mycotoxin Binder on Performance, Lymphoid Organs, Blood Parameters, Immune Response and Haematology Parameters of Broilers Exposed to Aflatoxin B1

open access: yesVeterinary Medicine and Science, Volume 11, Issue 6, November 2025.
Broilers fed diets contaminated with 200 µg/kg AFB1 showed poor growth performance throughout the period. These adverse effects of aflatoxicosis may be associated with liver dysfunction, immune dysfunction and inflammation of immune organs. However, supplementation of 1 g/kg MAG counteracted the negative effects caused by AFB1, reducing liver ...

A transmissible disease of the bursa of Fabricius of ducks [PDF]

open access: yesAvian Pathology, 1994
Longitudinal surveys of commercial Pekin ducks from four farms with a history of poor flock performance and high mortality rate showed that there was lymphoid depletion of the bursa of Fabricius in most ducks selected from 7 days of age onward. Such lesions were not present in Pekin ducks from a farm with a history of good flock performance and low ...

The Effect of Dietary Metabolisable Energy and Stocking Density on Growth Performance, Blood Metabolites, Nutrient Utilization, and Carcass Traits in Broiler Chicks

open access: yesFood Science &Nutrition, Volume 13, Issue 9, September 2025.
High energy levels in the diet increased weight gain and improved feed conversion ratio. Increasing the stocking density to 16 birds/m2 did not negatively impact broilers performance. ABSTRACT This study aimed to evaluate the effects of dietary metabolisable energy (ME) levels and stocking density (SD) on growth performance, carcass traits, blood ...

Influence of Citrus sinensis Seeds on the Growth Performance, Ceca Bacterial Population and the Immune System Response of Broiler Chickens

open access: yesVeterinary Medicine and Science, Volume 11, Issue 5, September 2025.
Citrus sinensis seed powder at 0.5% in broiler diets optimized caecal bacterial populations, while 4% supplementation increased IgG levels compared to antibiotic use. These findings suggest potential benefits of orange seeds as a phytogenic feed additive, despite the need for further studies on their bioactive compounds and mechanisms.
