| Summary: | The hot and humid tropical climate has a highly
detrimental effect on growth. feed efficiency,
survivability and disease resistance In broiler
chickens. Commercial broilers are particularly
susceptible to heat stress because metabolic heat
production increases with growth rate while heat
dissipation does not. We examined the
possibilities of modifying the birds' own natural
coping mechanisms through early age stimulation.
Two experiments was carried out to investigate
the effects of stress attributed to early age
fasting on heat tolerance and disease resistance
in broiler chickens at market age, and to
ascertain the mechanisms involved on a molecular
level |
