Özet
The relationships between small intestine morphological values and body weight gain of slow-growing broilers with cumin essential oil (CEO) added to their diets at different levels and raised in a free-range system were investigated. A total of 450 slow-growing, 1-day-old chicks were used. The animals were divided into three groups and fed with 0 ppm (control group), 200 ppm (C200 group), or 400 ppm (C400 group) CEO added to their feed for 70 days. According to the results of the morphological analysis, while diets with CEO decreased the villus and crypt dimensions in the duodenum and ileum, they decreased only villus dimensions and the ratio of villus height to crypt depth in the jejunum. The morphological parameters of the small intestine showed positive correlations with each other in all groups and were found to be statistically significant. However, differences were observed in the correlations between body weight gain and morphological intestinal parameters. Body weight gain, villus width, and crypt depth in the control group were positively correlated, while the same traits tended to show negatively correlations in the C200 and C400 groups, but not in a statistically significant manner. It was concluded that 200 and 400 ppm CEO added to the feed of slow-growing broilers raised in a free-range system have a suppressive effect on the morphological parameters of the small intestine and, according to correlation analyse, it has a slowing effect on body weight gain. © 2023, Verlag Eugen Ulmer.
