The impact of various calcium sources offered to Arabic hens during their early-laying stage on calcium consumption and egg production.

Objective: The research was conducted to calculate feed, calcium (Ca) intake, Ca requirements, and egg production for Arabic hens during the early egg-laying period.

Materials And Methods: A total of 135 30-week-old Silver female Arabic pullets were randomly allocated to one of three treatments with five replicate cages with a semi-scavenging system of nine pullets per cage in a completely randomized design and allowed to choose Ca from limestone and oyster shells. As a control (T1), pullets were only given a complete feed with Ca and phosphorus percentages according to Hy-line International in 2018.
