ABSTRACT
This study aims to evaluate effect cage location in closed house system on Hy-Line laying hens growth performance, microclimate, ammonia (NH3) and carbon dioxide (CO2) concentration, and dust particle.. A total 5,051 heads laying hens used were Hy-line laying hens aged 28 weeks reared for 28 weeks on the experimental diet. A completely randomized design (CRD) with three treatments and twelve replications. The parameters observed was growth performance, microclimate, and health. The cage location consisted Z1: near inlet; Z2: middle of housing; Z3; near outlet. Result were analyses general linear model (GLM) and if there is a significant effect (p < 0.05) continued with Duncan multiple ranged tests. The effect of cage locations was presented significant differences (p < 0.05) on the average daily feed intake (ADFI), egg mass, temperature, NH3 and CO2 concentration. the first cage location (near inlet) in the closed-house system resulted the highest egg mass, the lowest temperature, and the lowest of ammonia and carbon dioxide concentration. It can be concluded first cage location near the inlet were the best one to support good production performance of Hy Line Laying hens.
