Abstract
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.
