A study was conducted in 55 week old laying hen (n=225) to
determine efficacy of calcium and phosphorus supplements in
improving egg and shell quality traits. Birds were randomly
divided into three groups, one control and two treatments. Group
I (control) was offered basal diet without any additional
supplement source of Calcium and phosphorus. Group II was
supplemented Ayucal liquid (Dabur Ayurvet Ltd.) @15ml/ 100
birds/ day in drinking water and group III administered Ayucal
premix@15g/ 100 birds/ day in feed from 55th- 62nd week age.
Parameters studied were egg weight, shell thickness, breaking
strength, number of shell defects and specific gravity of egg.
Results of experiemental study revealed that supplementation of
Ayucal liquid & Ayucal premix (supplied by Ayurvet Ltd. Baddi,
India) improved overall egg and shell quality traits that can be
correlated well with the activity of herbal constituents of the
products owing calcium and phosphorus mineralization properties.
