An experiment was conducted to investigate the effects of almond fruit meal fermentation using Aspergillus niger on growth performance and intestinal morphology of broiler chickens. Almond fruit meal was fermented in an air-tight plastic bucket for 7 d after inoculation with 20 ml of spore suspension of Aspergillus niger per kg of meal. The fermented fruit meal (FAFM) and unfermented almond fruit meal (UAFM) replaced maize in a control diet at 150 g kg-1 and fed to 360 d-old broiler chicks in 3 dietary treatments, 6 replicate groups of 20 chicks each over a 42 d period. Broilers fed a diet with FAFM had greater daily weight gain (P<0.05), daily feed intake (P<0.05) than those on UFAM and control group in whole period; had an improved feed to gain ratio (P<0.05) only at 1-21 d period. The retention coefficients of nitrogen and fat were significantly increased (P<0.05) in broilers fed FAFM and control compared to the UAFM. There was no significant difference (P>0.05) in fibre retention. There were significant increases (P<0.05) in the relative lengths of duodenum, jejunum, ileum and whole intestinal length of broilers fed UAFM compared with either FAFM or control broilers. Similarly, small intestinal weight was greater in UAFM than FAFM broilers. Histological observation revealed loss of mucosa gland in the jejunum of broilers fed UAFM compared with those fed the control and FAFM. The results indicate that Aspergillus niger fermented almond fruit meal manifested positive influence on performance, retention of nutrients and intestinal morphology of broilers. 1477690235.php
