Lymphatic involution and early mortality in the young chicken produced by 2.2 GeV protons [PDF]

open access: yes, 1972
Young single-comb white Leghorn cockerels were subjected to single acute doses of either 2.2 GeV protons or 250 kVp X-rays. Since young chickens exposed in the lethal range die within 48 hours of exposure, an hourly tabulation of deaths was recorded for ...

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 ...
