Effects of curcumin supplementation in aflatoxin B1-contaminated diet on the performance and egg quality of laying duck

Abstract

The objective of this study was to asses the effects of curcumin supplementation in AFB1-contaminated diet on the performance and external egg quality of laying duck. Fourty eight seven-months female Alabio ducks (Anas platyrinchos Borneo) were randomly allocated into 3 groups with 4 replicates of 4 ducks per pen: (1) Control (commercial feed); (2) AFB1 100 ppb diet (Control + AFB1-contaminated diet} and (3) CUR diet (AFB1 100 ppb diet + 0.05% Curcumin). Dietary trial was conducted for 42 days. Ducks were weighed on day 21 and 42 to calculate the body weights changes. The percentage of egg production was calculated since 21st day. Egg weight, shell thickness, and yolk weight percentage were determined in egg samples collected on the last three days of the experiment. Data were subjected to analysis of variance (IBM SPSS 21). Results showed live weight and weight gain were signifcantly lower in AFB1 diet (P< 0.05), and curcumin supplementation could diminish the negative effect of AFB1. However, treatments had no significant effects (P > 0.05) on egg production and egg external qualities. It was concluded that curcumin supplementation has positive effects on the laying duck performance which ingest AFB1-contaminated diet.
