Résumé
This experiment was performed to evaluate the effects of replacing different levels of soybean meal with sunflower meal (with and without enzyme) on cecal volatile fatty acid profile and intestinal microbial colonization in laying hens. In this experiment, 360 laying hens from the age of 47 to 57 weeks, in 9 treatments and five replications (8 hens in each replicate) were performed as a 3 × 3 factorial experiment in a completely randomized design for ten weeks. The results showed that the replacement of 30 and 60 percent sunflower meal and enzyme (100 and 200 gr/ton) has significantly improved the concentration of n-valeric acid on the cecum of laying hens (P< 0.05). Simultaneously, increasing 30 percentage of sunflower meal or 100 of an enzyme enhanced isovaleric acid, n-butyric acid, isobutyric acid, propionic acid, and acetic acid (P< 0.05). Reduction in intestinal log Ecoli was discovered for samples treated with 30 and 60 percent of sunflower (P
