| Popis: | The use of antibiotics is currently banned because it can cause resistance to pathogenic bacteria and cause residues in products. This study aimed to see the effect of drinking water containing uronic acid extracted from Sargassum crassifolium (S. crassifolium) on the immunity of Lohman chicken eggs. One hundred and twenty laying hens were divided into 2 groups: (1) chickens given commercial feed containing antibiotics and (2) feed without additional antibiotics. The chickens were randomly assigned to one of the 5 brown seaweed supplementation treatments in drinking water A1=0.0% S.crassifolium (control); A2=2.5% S.crassifolium; A3=5.0% S.crassifolium; A4=7.5% S.crassifolium; A5=10.0% S.crassifolium. The study used a completely randomized factorial design of 5 treatments, 2 factors, and 3 replications. Each replication consisted of 6 heads of laying hens. There were differences between treatments on titer antibody but were no difference on infection of Salmonella sp the Conclusion. The uronic acid extracted from S. crassifolium has been able to increase the immunity of Lohman chicken eggs. |
