Efforts to Control Salmonellosis Through the Supplementation of Zingiber zerumbet (L.) Smith Extract in Feed for Broiler Chicken Health

Abstract

The study aims to control Salmonellosis through the addition of Zingiber zerumbet (L.) Smith extract as a feed additive to maintain the health of broilers’ visceral organs and blood serum. An experimental method was employed using Completely Randomized Design (CRD), which included five treatments: T0 (basal diet), T1 (basal diet + S. enteridis infection), T2 (basal diet + S. enteridis infection + 0.33 % Z. zerumbet extract), T3 (basal diet + S. enteridis infection + 0.67 % Z. zerumbet extract), and T4 (basal diet + S. enteridis infection + 1 % Z. zerumbet extract). Each treatment was repeated five times. As a result, the treatments affected the percentage of spleen and bursa weight. The highest percentage of spleen weight was found in T1, and the highest percentage of bursa weight was indicated in T3. The treatment did not affect the serum biochemistry variables, except for globulins, whose highest level was found in T4. It is concluded that the ethanolic extract of Z. zerumbet is a potentially safe feed additive for the control of Salmonellosis in broiler chickens.
