"Evaluating Eggshells as a Sustainable and Economical Alternative Calcium Source in Poultry Feed"

This study evaluates eggshells as a cost-effective and eco-friendly alternative source of calcium in chicken feed versus traditional sources of calcium supplements based on their effect on chicken growth, egg weight, and egg production. The experiment was conducted for six weeks in which chickens were divided into an experimental treatment group (receiving eggshell calcium) and a control group (receiving traditional sources of calcium). Information was gathered on six-week body weight of chickens, weekly egg weight from weeks 36 to 40, and overall egg production for the duration. Statistical analysis was conducted using One-Sample T-Test under SPSS, which indicated significant difference (Sig. = 0.000) in all parameters recorded. The treatment group was heavier (411.39g vs. 185.55g in the control group) but compared to the latter, had better egg weight relatively (63.20g vs. 60.70g) and moderately improved egg yield (5.35 vs. 4.70 eggs/bird). Findings of the study confirm eggshell calcium can be used effectively and inexpensively as a supplement in poultry feeds to boost development and production with ease while it promotes efficient schemes of waste disposal in poultry business.
