Effect of Addition of Waste Jam Mixture on Relative Feed Value and Aerobic Stability of Alfalfa Silages

Abstract

This research was planned to determine the effects of adding waste jam mixture to alfalfa silages on relative feed value (RFV) and aerobic stability. Experimental groups: Liquid fraction RI: 50 mg/20mLpure water, RII: 100 mg/20mL pure water / kg alfalfa, solid fraction RPI: 30mg / 30mL pure water and RPII: 60 mg/30mLpure water/kg alfalfa. To the control group was added 20mL/ kg alfalfa pure water.The alfalfa, which was harvested at the beginning of flowering and withered, was left for fermentation by adding jam. After the silages were opened (60 days), a 7-day aerobic stability test was performed in the laboratory.The addition of jam and jam particles significantly increased the digestible dry matter content (DDM) of the silages compared to the control group (P<0.01). DDM contents in control, jam and jam particle groups were 67,65%; 69,98%; 68,74%; 68,95% and 69,53% respectively. In addition, dry matter consumption (DMI) amount and relative feed value (RFV) increased in jam groups. Adding jam and jam particles to alfalfa silages increased carbon dioxide (CO₂) production in the aerobic period (P<0.01).During this period, yeast counts increased rapidly (P<0.01) in silages, while mold was detected in the RPII group. When the data obtained are evaluated; It was concluded that alfalfa silages with 50 mg/kg liquid jam or 50 mg/kg jam particles added can remain stable for 7 days in the aerobic period, and metabolic energy calculated from DDM (ME_DDM) and RFV are positively affected.
