three different seasons of the year under Bangladesh conditions. Two strains
of broiler breeder flocks were reared separately on floor from 22 to 48 weeks
of age and eggs laid by these birds during spring, summer and monsoon were considered
for this study. Each season was treated as treatment with 4 sets, each of 50
eggs as replicates within a treatment. One thousand two hundred hatching eggs
(600 from Starbro and 600 from ISA MPK) were incubated in a James-way forced-draft
electric incubator and the required records were kept during incubation and
following taking out of hatches. The results of the experiment showed that hatching
performance of eggs from Starbro was significantly better in spring than those
observed during summer and monsoon. The hatchability results from ISA MPK also
showed trends similar to Starbro but data did not differ significantly among
seasons of the year. It may be concluded from the study that it is better to
consider hatching of large number of eggs during spring if the broiler parents
are reared in open-sided house.]]>Basnet, T.B., S.C. Mohapatra, S.K. Agarwal and G.B. Rao,19762271271Kumaraswany, K. and V.
