Pullets had higher bursal and thymic weight indices and more antibody response to La Sota vaccination than broiler chickens (Gallus gallus domesticus)

Veterinary Medicine and Science, Volume 6, Issue 3, Page 462-469, August 2020., 2020
La Sota vaccination, used in protection of chickens against Newcastle disease, did not produce clinical signs or lesions in vaccinated broiler and pullet chickens, however, pullets produce higher antibodies than broilers because of their higher bursa weight index.
