Abstract
This study was conducted at the University of Maiduguri Poultry and Research farm, to investigate the effects of various calcium sources on the productive and egg quality performance of spent layers. A total of ninety (96) Black Harco layers at the age of 58 weeks were randomly assigned in to four different treatment and replicated two times with12 birds each in a completely randomized design (CRD). They were reared on varying calcium and phosphorus sources name bone meal, oyster shell, periwinkle shell and limestone for treatment T1,T2,T3 and T4. The study revealed that feed consumption and feed conversion Ratio did not differ (P<0.05) significantly among treatment groups. Egg weight, Albumen length and Haugh unit also did not differ significantly. However, albumen height, albumen width and albumen index and shell thickness differ significantly between treatment groups and was in favour of limestone. This indicates that the various Ca/P sources affect these parameters. The mortality record of 5.20% recorded was in treatment T3 and T4. The study concluded that the various Ca/P sources did not affect feed consumption and FCR but some egg quality factors.
