Egg Weight and Egg Shell Thickness As Affected By Dietary Calcium

I. E. Ebenso
KEYWORDS: EGG WEIGHT , EGG SHELL THICKNESS AS AFFECTED BY DIETARY CALCIUM

ABSTRACT:

Graded levels of dietary inclusions of oyster shell and bone meal were used as calcium sources todetermine their influence on egg weight and egg thickness for laying chicken in cages, under tropicalconditions. Birds were allocated at random to 8% oyster shell and 2% bone meal in treatment 1; 7% and 3% in treatment II; 6% and 4% in treatment Ill; 5% and 5% in treatment IV respectively. Egg weight and egg shell thickness did not show significant differences (P> 0.05). Increasing calcium level above 2% depresses egg shell quality, obtained by using 5% oyster shell and 5% bone meal in the diet.
