Abstract
Overcrowding of broiler chicks due to less space
induced harmful effects which act as predisposing
factor in reduction of production and performance in
poultry. Supplementation of antistressor products
can ameliorate adverse effect of various stressors
in poultry. An experiment was designed by inducing
overcrowding stress and its management by
supplementation of polyherbal antistressor,
adaptogenic and immunomodulator formulation
Stresroak in broiler chicken. One hundred and fifty
day old broiler chicks were randomly divided into
five groups of 30 chicks each. Groups I, II and III
served as control and were offered with basal diet
only. Group I served as control with normal space.
The chicks in groups II and III (positive control)
were provided space 25% and 50% lesser than normal,
respectively. The bird in therapeutic group IV and V
were provided 25% and 50% less space along with
antistressor Stresroak @1g/1kg of feed,
respectively. Growth and performance related
parameters like feed consumption, body weight, feed
conversion ration (FCR) were evaluated in addition
to haematological parameters. Polyherbal formulation
not only improved growth and performance in birds,
but also normalized the haematological parameters.
It was concluded that Stresroak exhibits
antistressor and adaptogenic activity to ameliorate
the overcrowding stress in poultry.
Keywords: stressors, overcrowding,
