COMPARISON OF ANTIBODY TITRES OF NEWCASTLE DISEASE VIRUS IN RANDOMLY COLLECTED SERA AND EGG YOLK OF LAYERS

Abstract

A study was conducted to compare the Newcastle Disease (ND) virus antibody titre in randomly collected sera and egg yolk of layers using haemagglutination inhibition (Hl) test. The mean logeHI titre values detected in sera and egg yolk were 4.50 and 5.68 respectively. Statistically there was significant difference between the two means (p < 0.03). Egg yolk samples may be used as a test material for detection of titre of ND virus antibodies in layers. But when egg yolk is the test material, the H! titre detected tends to be significantly higher.
