Abstract:

The need for roughage required for animals are provided from meadows and pastures and sources such as fresh forage, hay, silage and haylage obtained from field agriculture. In periods when the weather is hot, meadow-pastures come to the fore as the source of roughage, and as the weather begins to cool, silage has become common. The aim of current study was to determine the fermentation traits of sole and binary mixtures (80:20, 60:40, 40:60 and 20:80%) of forage pea “FP” (Pisum arvense L.) and oat (Avena sativa L.) “O”. Plants were harvested and chopped in size of 2 cm in size. Then, they were filled in plastic bags according to the mixture ratios, and stored at 25 ± 2 °C for 45 days. End of the 45. day, silo samples were investigated for dry matter ratio, pH, crude protein ratio, lactic acid, acetic acid, butyric acid, lactic/acetic acid ratio, and some mineral nutrients (potassium, phosphor, calcium, magnesium, and iron). According to the Flieg score, silages have the highest value excepted sole forage pea and, they were in good quality class of silage. The highest crude protein content was determined in sole forage pea (19.36%), 80FP+20O% (17.91%) and 60FP+40O% (17.61%). The ratio of lactic/acetic acid, which is the stimulant of fermentation development and reveals the homofermentative character, was determined in the mixture of 9.455% with in 60FP+40O%. Mineral nutrients in all treatments were found within the livestock requirement excepted sole silages. As a result, it was determined that the mixture of forage pea and oat 80+20% and 60+40% silages were better in terms of silage quality.
