Abstract/Description: | To test the efficacy of zinc in ameliorating aflatoxicosis, day-old broiler chicks (n=240) were divided into 6 treatment groups containing 5 replicates of 8 birds each (T1-control; T2-T1+250ppb AFB1; T3-T1+20ppm Zn; T4-T1+40ppm Zn; T5-T2+20ppm Zn; T6-T2+40ppm Zn diet) and the experiment was conducted from day 1 to 42 days of age. The results showed that the CMI and HA titre values in T2 was lower (P<0.05) than T1. The CMI and HA titre values of T5 did not vary (P<0.05) from T1 and T2. The CMI value in T6 was higher (P<0.05) than T2 and statistically similar to T1. Grossly, swelling, enlargement and paleness with focal dark area; and histopathologically, moderate to severe degenerative changes in hepatic cells with greater disorganization in tissue marking the hepatotoxicity and proliferation of bile ducts along with periportal infiltration of heterophils and MNCs (mononuclear cells) in liver of T2 were observed. In intestine, degenerative changes, sloughing and focal area of severe necrosis along with infiltration of inflammatory cells were seen in T2. Mild gross and histopathological lesions were also reported in liver and intestine of T5 and T6. The crypt depth in T2 was higher (P<0.05) than T1. The crypt depth in T3 to T6 was statistically similar to T1. The villus length/crypt depth ratio in T1 was higher (P<0.05) than T2. The villus length/crypt depth ratio in T3 to T6 was statistically similar to T1. It was concluded that aflatoxin contamination at 250 ppb level in diet resulted in reduced immunity; gross and histopathological lesions in liver and intestine; increased crypt depth and decreased villus length: crypt depth ratio. Inclusion of zinc (40 mg/kg diet) partially ameliorated the adverse effect of aflatoxicosis on immunity; pathology of liver and intestine; and jejunal morphometry in broiler chickens. |
