Morphology and function of broiler chicks's intestinal feed by ration containing Myriophyllum spicatum

This study was conducted in Iran for the first time. Water milfoil (Myriophyllum spicatum) was used in 180 day-old broilers chicks fed Ross «308» in the three treatments and four replications which 15 pieces were used in each replication. Treatments consisted of 0، 5 and 10 percent of dry and powdered of water milfoil. The data analyzed with Excel and MSTATC software and also، Duncan test. The amount of food intake، weight gaining and feed conversion ratio in 10، 28 and 32-day-old were determined and in 32-day sampling from duodenum tissue were done. In weight gaining، the control treatment showed the best result and treatment 5 was gain weight higher than treatment 10. No difference was observed for food conversion ratio in compare to control treatment. In morphology of intestinal the results showed، in 10% treatment the intestinal villi length was higher and had significant difference with 5% and control treatments of water milfoil plant. The crypts depth and epithelium thickness in 5% treatment was higher and showed significant difference compare to control treatment.
