Abstract

The present study was aimed at studying the effects of inclusion of pomegranate seed extract to fat-containing diets on nutrients digestibility, intestinal microflora and performance of broilers. A total of 320 one-day-old broiler chicks (Ross 308) were selected in a 2 × 2 × 2 factorial experiment in a completely randomized design with 4 replicates of 10 birds of each. The dietary treatments consisted of pomegranate seed extract (0 and 2%), commercial Nutriad® antioxidant (0 and 0.01%) and soybean oil without antioxidant (0 and 6% during the grower period and 0 and 8% for finisher period). The chicks were reared from 1 to 10 days in one group. On the eleventh day, 10 chicks per pen were randomly allocated to each cage per replicate. Data were performed in generalized linear model (GLM) procedures in SAS at 5% level of significance and the least square means correction after Tukey’s test was used. Commercial antioxidant improved crude fat digestibility and decreased population of caecum Lactobacillus, but pomegranate seed extract improved crude fat digestibility and increased caecum Lactobacillus population. Due to positive effects of pomegranate seed extract in fat containing diets on fat digestibility and Lactobacillus bacteria in caecum, it could be concluded that using pomegranate seed extract in fat containing diets could be useful.
