Abstract
The study aimed to observe the effect of adding probiotic powder on the hematological status and egg production in layer-phase laying hens. This research was conducted for 30 days, located in a layer farms in Sumedang Regency, West Java. The production of probiotic powder was carried out at the Central Laboratory, Padjadjaran University. The blood was analyzed at the Multitest Commercial Laboratory, Margahayu Raya, Bandung City. The variables observed in this study were the levels of erythrocytes, leukocytes, hematocrit, and egg production in layer-phase laying hens. This study used an experimental method with statistical analysis using a completely randomized design (CRD) with four levels of probiotics (0%, 2%, 3%, 4%) and five replications. The research data were analyzed using the 0.05% Variety Print Test. The result of this research showed that the addition of probiotic powder gave the same effect on the levels of erythrocytes, leukocytes, and hematocrits of laying hens. However, probiotic powder increased egg production along with the addition of the dose of probiotic powder. It can be seen that 2%, 3% and 4% probiotic powder increased 64.1%, 41.5% and 118% egg production compared to control.
