This study was carried out to evaluate the effects of immune
enhancers such as Beta-glucan on some blood parameters of quails
such as white blood cell differential count, and level of viral
antibody for Newcastle disease by using the hem agglutina
tion
inhibition (HI) test .
Seventy five, 1 days old Japanese quail chicks were randomly
divided into three groups of 25 chicks, with similar initial average
body weight.
This experiment was conducted at Kharabo farm, Faculty of Agriculture,
University of Damascus. A total of 252 chicks of Japanese quail breeder females
were distributed on the first day of life into two groups, Gicks in G1 were
reared from 1-28 day
s of age under ideal required temperature according to
their age, while chicks in G2, were subjected to heat stress from 8 am to 5 pm at
42 °C from the first day of hatching until 28 day of age and to the ideal
required temperature from 5 pm until 8 am. Chicks of each group were
distributed into three subgroups, with three replicates per subgroup.

Universityin order to determine the effect of heat sress and level of vit. C on the
blood indicators of of Japanese quailc A total of 252 females Chicks were
distributed randomly into
two groups (G and G2) at one day of age, The chicks
in G1were subjected to an ideal temperature required according to their age up
to 30 days old, while the chicks in G2 were subjected to heat stress at 42 °C
during the daytime from 8 am to 5 pm and to ideal temperature from 5pm to
8am for the same period of rearing. Chicks of each group were distributed into
three subgroups given three levels of vitamin C: 0, 10 and20 g/l, with three
replicates for each sub-group during the rearing period. Blood samples were
collected from eighteen birds selected randomly from each group. Results
indicated that there was a significant increase in both red blood cells and
hemoglobin in the stressed group.
