Özet

This study was conducted to investigate the effect of dietary raw sour cherry kernel (RC) or fermented sour cherry kernel (FC) on apparent digestibility, ileal morphology, and caecal microflora in broiler chickens. Raw sour cherry kernel was fermented by Aspergillus niger for 7 D. A total of 343 one-day-old Ross 308 male chicks were assigned to 7 dietary treatments consisting of 7 replicates of 7 broilers each. All birds were fed with a commercial diet or diets supplemented with 1%, 2%, or 4% RC or FC. The experimental period was 42 D. Apparent dry matter (DM), nitrogen and ash digestibilities were diminished (P < 0.05) by dietary RC inclusion, although dietary FC did not negatively affect (P > 0.05) nutrient digestibility. Dietary 1% FC increased (P < 0.01) the villus height to crypt depth ratio (VH:CD) compared with the other treatment groups, although RC4 reduced the villus height (VH, P < 0.001) and VH:CD (P < 0.01), compared with the control group. Dietary treatments had no effect (P > 0.05) on the crypt depth (CD). Birds fed 1% FC had the highest (P < 0.05) caecal Lactobacillus spp. counts among the treatment groups. Enterococcus spp. and Escherichia coli counts in cecum were not affected (P > 0.05) by dietary treatments. The results showed that the dietary inclusion of 1% FC improved ileal morphology and caecal microflora without any adverse effect on the apparent digestibility. These results indicate that FC has the potential to be a feed additive which improves intestinal health for broiler diets.
