Abstract
Common Reed (Phragmites australis (Cav.) Trin. Ex Steud, which is remained inactive and grown in saline
drainage channels, has been seen as an important potential to reduce the roughage deficit needed in animal nutrition. For this purpose, some yield, fermantation, chemical and nutritional characteristics of P.australis herbage and silage obtained from the end of the vegetative stage (EVS), the beginning of panicle (BP) and the full panicle stage (FPS) were determined. The study was carried out in 2021-2022 in Igdir, which is located in the North-East of Turkey. The results showed that the forage yield characteristics increased as the development period progressed and also that high lactic acid, low pH, acetic, propionic and butyric acid contents desired in silo feeds were obtained from the cuttings at FPS. In addition, ammonia production was low in silages at BP and FPS, but high the fleig score. It was observed that the dry matter digestibility, metabolic energy and relative feed value were higher while dry matter and crude protein ratio, acid detergent fibre and crude ash content of herbage according to silage were lower. On the other hand, the desired chemical and nutritional values in both herbage and silage were determined during the most suitable BP. As a result, it was determined that the common reed was appropriate to harvest in FPS for a silo feed with high yield and fermentation properties. In addition, it was concluded that the herbage and silage harvested at BP produced a higher quality feed material in terms of nutritional and chemical composition, respectively.
