Abstract
The present study was conducted to evaluate
the effects of thermal conditioning on blood pH
in native chicken Aseel (ASL), Naked Neck (NN)
and its cross variety such as Aseel x Nandanam
chicken-4 (ARW) and Naked neck x Nandanam
broiler-3 (NNB3). Chicks from four varieties
were divided into control (C; 28±1°C) and heat
exposed (H; 39±1º C for 2 hours during 0-2 and
5-6 weeks of age). Chicks from H group (HE) and
chicks from control group (CE) were exposed to
39±1°C for 4 hours daily on 12th week of age. On
14th, 42nd and 84th day, blood was withdrawn and
pH was measured. On 14th and 42nd day, blood
pH was significantly (P<0.01) high in H group in
all the four varieties. However, CE group chicks
had significantly (P<0.05) high blood pH (Respiratory
alkalosis) on 84th day, compared to H
group. Based on the results, it can be concluded
that early thermal conditioning develops heat
resistance in later part of life.
