Patogen Bacteria and Visceral Organ Weight of Native Chicken in Feed Herbal Supplementation

A healthy gastrointestinal tract is the most critical assurance for
optimal poultry production. The gut health of poultry is intimately linked to feeds and feeding. This study aims to determine the effect of herbal supplementation as a feed additive, through feeding, on the relative weight of visceral organs and the number of pathogenic bacteria in the small intestine. The method used was the experimental method, which consisted of 2 treatment groups, namely group T0 (chickens were only given basal feed, without the addition of herbs) and group T1 (chickens were given basal feed and additional of 1% herbs). Each group consisted of 50 cross�breeding native chicken, namely Joper and KUB. The variables measured were the relative weight of the visceral organs (heart, pancreas, liver, spleen and bursa of Fabricius) and the number of pathogenic bacteria in the small intestine (Clostridium, Staphylococcus, Mycobacterium, Pasteurella). Data on the relative weight of visceral organs and the number of pathogenic bacteria in the small intestine were analyzed using quantitative descriptive
analysis. The results indicated that giving Joper and KUB 1% herbal supplementation had no effect on the relative weight of the visceral organs examined; nevertheless, no pathogenic bacteria were detected in the small intestine after giving Joper and KUB 1% herbal supplementation. This study concludes that no harmful bacteria are detected in the small intestine of native chicken, both Joper and KUB, and that 1% herbal supplementation as a feed additive has a good effect on the health of the heart, digestive glands, and lymphoid glands.
