Abstract
Coccidiosis has a major impact on poultry industry as it affects
broiler and layer birds of all age groups. Caecal
coccidiosis, caused by
Eimeria tenella
is a very devastating
enteric disease in broiler, which involves huge economic loss.
In
present study,
experimental infective dose of
Eimeria tenella isolated from field was determined
in broiler chicken and subsequent alterations in different plasma
biochemical constituents were evaluated at interval of 5th,
7th and 9th day of post inoculation (PI) with the selected dose of
20000-25000 sporulated oocyst per bird. The dose was selected
based on titration. A significant increase in plasma glucose,
total cholesterol level and aspartate aminotransferase (AST)
activity were observed where as a significant decrease in the
level of total plasma protein, albumin, globulin, triglyceride and
alanine aminotransferase (ALT) activity were evident during
infection
Highest degree of infection. was found on 7th
day
PI. Onward 9th
day of PI onward clinical recovery was confirmed on the basis of
pathognomonic
caecal lesion score, clinical signs and symptoms.
