The Effect of Coriander on the Histological Structure of the Intestine and Liver in Broilers

Medicinal plants are used in poultry feed due to their beneficial effects on the intestinal microflora, digestibility of nutrients, intestinal morphology, aspects that are found in the quality of meat and eggs. Currently, due to its characteristics, coriander is widely used in the food, pharmaceutical and medical industry, in the cosmetics and perfume industry, but also in the zootechnical field, as an alternative to antibiotics, in raising young animals and birds. In this context, the aim of this study was to evaluate the additional effects of the diet of chickens with coriander powder on intestinal and liver morphology. The study was performed on a number of 24 broilers (ROS 308 hybrids), male, divided into two groups, each group with two replications, 6 individuals / group: Control group (CG) fed only by the basic diet and the experimental group (CoG) in which the basic diet was supplemented with 1% coriander powder. The duration of the experiment was 42 days. Supplementation of the basic diet of chickens with 1% coriander powder led to an increase in the analyzed histomorphometric parameters, the differences compared to the control group (CG) being significant (p0.05) for the width of the villi. In addition, at the hepatic level, dietary supplementation with coriander powder led to vascular hypertrophy, the presence of perivascular leukocyte infiltrates and the manifestation of cytoplasmic vacuolation of hepatocytes in the perilobular territories. Histomorphometric analysis of the data obtained in this study and histological changes in the liver provide new information on the use of coriander seed powder in broiler feed, as a potential promoter of their growth.
