Profil Hematologi dan Pertambahan Bobot Badan Harian Ayam Broiler yang Diberi Cekaman Panas pada Suhu Kandang yang Berbeda
ABSTRACT: A research have been
conducted to find the impact of heat stress at 3 level of cage temperature on
hematology profile and broiler daily body weight gain. Sixteen broilers (strain
Cobb) at the age of 20 days were randomly divided to 4 groups. First group was
control group that treated without given heat stress (KL). Second, third, and
fourth groups were treated with heat stress in cages with temperature,
respectively 33 ± 1oC, 36 ± 1oC, and 39 ± 1oC. Heat stress was given 4 hours
daily during 7 days consecutively. The result indicated that cage temperature
up to 36 ± 1oC has not significantly affected hematology profile and broiler
daily body weight gain. The impact of increasing temperature have been found at
cage temperature of 39 ± 1oC after 7 days of treatment, which were the
increasing number of leucocytes, decreasing number of erythrocytes, and
decreasing of broiler daily body weight gain. The broiler of the age above 20
to 27 days that exposed heat stress during 4 hour per day in the cage
temperature of 39 ± 1oC can obtain heat stress in serious level.
