Experimental birds and their management: The
experimental laying birds were housed in a battery
system and each of the replicate of two birds was put in
a separate cages. After one week of acclimatization, the
seven experimental diets were randomly assigned and
fed to the layers ad libitum for a total of four weeks. The
body weights of the layers were determined for the
whole replicate on the onset of the experiment and once
a week till the end of the experiment. This data was used
to calculate weight gain. Each of the 2 replicates of the
treatment group (T1, T2, T3, T4, T5, T6 and T7) had its
feed and bucket weighed and then the groups was fed
ad libitum.
