The increasing needs of calcium in the diet of aged laying hens causing them to produce low quality eggs such as thin and shell less eggs. This problem in poultry raising industry caused a huge impact on the poultry raisers as losses were increased and resulted to lower profit. The high percentage of loss give rise to farmers to seek for potential calcium sources for feeds additives such as oyster shells. Hence, this study was conducted to determine the effect of Powdered oyster shell as feed additives to 1-year-old laying hens. It was conducted at Lacong, San Gabriel, La Union from July 12, 2021 to September 10, 2021.
Forty-eight 1-year old laying hens were used in the experiment. The experimental birds were randomly distributed into four treatments following Completely Randomized Design (CRD) replicated three times. The result of the study revealed that powdered oyster shell did not significantly influence the egg production in terms of henday. On the egg quality parameters, the effect of powdered oyster shell has found comparable in terms of egg classification and number of cracked eggs. however, the number of soft shelled egg showed significant result in bird supplemented with three percent powdered oyster shell. In terms of profit above feed medicine and stock cost, treatment two got the highest average net income of Php 419.02
