Abstract
Ever since the reduction of antimicrobial growth
promoters in animal feed, infectious diseases have re-emerged in certain parts
of the world, necrotic enteritis (NE) for one. The
current study determines the protective efficacy of egg yolk antibodies (EYAs)
in experimentally infected broiler chicken. Eighty (80), day-old broiler chickens were
procured and divided into four groups (G1-G4). Group G1
served as a negative control, while G2 served as positive control viz
infected with C. perfringens type A (1
x 108 cfu/ml) from days 17-19 of the experiment. Groups G3
and G4 immunized passively with anti-clostridial
IgY @ 1 ml per bird between days 21-24
via oral route, while 22nd and 24th days via I/M route,
respectively. Two killings were performed (days 26th and 35th)
and the birds were observed for growth performance, hematology and serum
biochemistry. The study results showed a statistically significant decrease in
growth, hematology and serum protein values, while elevation in serum enzyme
values of the birds in group G2 when compared to group G1.
The groups G3 and G4 (passively immunized) showed the
values less affected and close to the physiological ranges. Hence it was
concluded that anti-clostridial EYAs (IgY)
has ameliorative effects against experimental clostridial infection in broiler
chicken.
