Antibiotics are currently not allowed to be used because they can make pathogenic bacteria resistant and leave residues in products. The purpose of this study was to determine whether Lohman chicken eggs' immunity was affected by drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium). Sixty laying hens were divided into two groups: 1) chickens fed commercial feed with antibiotics, and 2) chickens fed feed without antibiotics. The chickens were randomly assigned to one of five treatments that included brown seaweed in the drinking water, A1 = 0.0% (control); A2 = 2.5%; A3 = 5.0%; A4 = 7.5%; A5 = 10.0%. Five treatments, two factors, and three replications were used in the completely randomized study design. Six laying hen heads were included in each replication. Titer antibody and unsaturated fatty acid were different between treatments, but Salmonella sp. infection was the same. It came to the conclusion that the lohman chicken eggs' immunity and unsaturated fatty acid levels were both enhanced by the uronic acid extracted from S. crassifolium.
