Effect of Particle Size of Egg Shell Mash with Treated Phosphoric Acid in Feed on Performance, and Status of Blood Plasma

Abstract

This research aimsis to study the effect of particle size of egg shell mash was treated with different levels of phosphoric acid on egg shell waste as a source of minerals in laying hens on performance, eggs production, and levels of Ca & P blood plasm of laying hens. Eggshell waste was collected from bakery, and separated into three treatments (K0/control) eggs shell washed with hot water of 80^°C; (K1) eggs shell washed with hot water of 80^°C + 3% phosphoric acid, (K2) eggs shell washed with hot water of 80^°C + 6% phosphoric acid. Egg shell was grounded into two particle mamely sizes 1 mm and 3 mm. Completely randomized design factorial (3x2) is used in biological tests used 72 chickens laying pullet phase. Chickens were randomly divided into 3 groups of phosphoric acid treatment and two measures of particle size. Each treatment was repeated three times using four laying chickens. The data was collected are feed consumption, body weight, egg production, and Ca and P levels in the blood plasm. Data were analyzed with analysis of variance according to completely randomized factorial design (3x2) in the form (3) treatment of phosphoric acid x (2) treatments particle size followed by Duncan’s different test to determine the effect of treatment. Results showed that greater levels of phosphoric acid used to wash the egg shell mash has effect significantly (P<0.01) on chicken body weight, blood plasm levels of calcium, phosphorus content of blood plasm. And not affected on feed consumption, calcium intake, and egg production. Difference particle sizes of egg shell mash is not affected on feed consumption, calcium intake, body weight, phosphorus content of blood plasm, and egg production, but significantly different (P<0.01 ) on blood plasm calcium levels. There was no interaction between phosphoric acid treatment with particle size of egg shell mash on performance, and levels of Ca & P blood plasm of laying hens
