Abstract

The use of antibiotic in poultry is not allowed due to its potential of bacterial resistance and its potential of residue in the poultry products. Brown seaweed (Sargassum crassifolium) contains sugar, sulphate, and uronic vitriol which display antibacterial and antiviral activities. This research aims to examine the effect of adding uronic sulfuric acid extracted from Sargassum crassifolium (Sc) on the weight of digestive organs (as % of BW) of Lohman hens. The stomach is a body part of poultry that consisted of yield, gizzard, ventriculus, duodenum, jejunum, ileum, caecum, and colon as rates of BW. One hundred and twenty laying hens were grouped into two main groups: (1) groups of laying hens given commercial antibiotic and (2) group of laying hens without antibiotic. The hens were divided into five treatments of brown seaweed (Sc) extract in drinking water: A1=0% Sc (control); A2=2.5% Sc; A3=5% Sc; A4=7.5% Sc; and A5=10% Sc. The research used Completely Randomized Design by Factorials Pattern consisted of 5 brown seaweed extract treatments as first factor and presence of antibiotic in feed as second factor; each treatment was replicated 3 times. Every replication comprised of six birds. The variables observed in this research were weight of viscera (as % of BW) of digestive organs. There were significant difference between hens given antibiotic and without antibiotic in feed on the crop, gizzard, proventriculus, jejunum, ileum, caecum, and colon weight; however there were no difference on the duodenum weight. It can be inferred that uronic sulfuric acid extracted from Sc has potency to increase the viscera weight (as % of BW) of laying Lohman hens. The treatment 10.0% Sc in drinking water without antibiotic in feed has the most elevated digestive organs weight.
