AbstractThis study investigated the effects of different levels of propionic acid addition on the aerobic stability characteristics of the total mixture ration. In the study, the effects of four different levels of propionic acid-based additives (0, 1.5, 3.0, 4.5%) on storage conditions of 26Â°C and 30Â°C. Feed samples were stored for 7 days, 3 replicates for each treatment group. Chemical and microbiological parameters were analysed in feed samples during aerobic stability. Temperature values and ambient temperature in each treatment were measured and recorded through temperature sensors for 7 days. The addition of additives in the study decreased the pH, dry matter, neutral detergent fiber, and yeast contents of total mixed ration, increased crude protein, eter extract, water soluble carbohydrate, lactic acid, and lactic acid bacteria contents and prevented mold growth. As a result of the research, the addition of 4.5% propionic acid allowed the total mixed ration to remain stable at 26Â°C for 7 days and 30Â°C for 5 days.
