IMPACT OF GINGER POWDER SUPPLEMENTATION IN BROILER DIET ON THE IMMUNE STATUE DEVELOPMENT AND SMALL INTESTINE MORPHOLOGY
AbstractA study using 300 one-day-old Ross-308 broilers was conducted to assess the effects of dried ginger root powder (Zingiber officinale) addition at percentages (0.2, 0.4 and 0.6) % in the treatments T1, T2 and T3 respectively on growth performance, immune status and small intestine morphology of broiler chickens at different ages. Compare with the control group (T0) without adding ginger powder.
The broiler body weight, body weight gain, viability, production index, and economic profit impacted with addition of ginger powder significantly (P≤0.05) increase in T3 at ages (1-21 d) and (36-42). As well as feed conversion ratio (FCR) particularly improved. In addition the morphological of small intestine goblet cells number in (duodenum , jejunum, and ileum), immunological delayed type of hypersensitivity DTH and ELISA titer against Newcastle(ND), Gumboro (IBD) and Infectious bronchitis (IB) diseases of broiler chickens were significantly higher (P≤0.05) at the ages 21, 35 and 42 d. While mortality and H/L ratio were significantly lower in the treatments of ginger supplementation especially in T3 compare with the control group without ginger addition.
