Hematological and Intestinal Responses of Broilers to Dietary Supplementations of Lactic Fermented Turmeric, Black Pepper or a Mixture of Both

The present experiment investigated the impact of administrations of lactic fermented turmeric, black pepper or a mixture of both into diets on the hematological parameters and intestinal ecology and morphology of broilers. Three hundred and ninety two broilers were spread to T0 (control), T1 (feed administrated with 1% lactic fermented turmeric), T2 (feed administrated with 1% lactic fermented black pepper) and T3 (feed administrated with 1% lactic fermented turmeric and 1% lactic fermented black pepper). Blood sampling was conducted at days 21 and 35, while intestinal sampling was at day 35. At day 21, erythrocyte counts were greater (P ≤ 0.05) for T1 compared to that for T2 and T3. Broilers in T1 had deceased (P ≤ 0.05) serum total triglyceride compared to that of T0 and T3. The concentration of globulin was reduced (P ≤ 0.05) in T3 than that in T0 and T1. At day 35, serum triglyceride level was more elevated (P ≤ 0.05) in T0 compared to that in T2 and T3 groups. Serum cholesterol as well as low-density lipoprotein levels were lower (P ≤ 0.05) in T3 than that in T0. Compared to other broilers, total protein and globulin concentrations were lower (P ≤ 0.05) in T3. A bigger (P ≤ 0.05) ratio of albumin to globulin (A/G) was seen in T3 compared to that in T1 and T2. Creatinine was greater (P ≤ 0.05) in T1 than in others. The titer of antibody toward vaccine of Newcastle disease was elevated (P ≤ 0.05) in T1 and T2 than in T0. The LAB counts were enhanced (P ≤ 0.05) in ileum of T1 and T2 than that in T0. Compared to T0, the villi height of jejunum was elevated (P ≤ 0.05) in treated broilers. In conclusion, administration of fermented turmeric powder improved erythrocyte counts, antibody titer toward Newcastle disease vaccine, LAB population and jejunal villi height of broilers.
