Özet
Simple Summary An investigation of poor aerobic stability in high-moisture total mixed rations (TMRs) for livestock feed was conducted in this study. TMR quality factors were discovered, and prospective approaches to increase its fermentation properties and overall stability were investigated. Using infrared thermography (IRT) measurements, it was suggested that dairy cow feeding methods can be optimized in the field by identifying portions with a higher center temperature and maximum temperature difference values. According to the findings, there is a significant potential for IRT to be used in feed management and preservation processes in the future, resulting in higher levels of productivity for livestock. A major objective of this study is to identify factors influencing the quality of high-moisture total mixed rations (TMRs) for livestock feed and explore possible manipulations that can enhance their fermentation characteristics and stability in order to address the problem of poor aerobic stability. Therefore, the current study utilized infrared thermography (IRT) to assess the aerobic stability of water-added TMRs in the feed bunker. By manipulating the moisture content of freshly prepared TMRs at four different levels through water addition and subjecting it to storage at two consistent temperatures, significant correlations between IRT values (center temperature (CT) and maximum temperature difference (MTD)) and key parameters such as lactic acid bacteria, water-soluble carbohydrates, and TMR pH were established. The first and second principal components together accounted for 44.3% of the variation, with the first component's load influenced by IRT parameters, fermentation characteristics, and air exposure times, while the second component's load was influenced by dry matter content and lactic acid concentration. The results of these studies indicate the possibility that feeding methods can be optimized by identifying portions with higher CT or MTD data using IRT measurements just before feeding dairy cows in the field. As a result, increasing the use of IRT in feed management and preservation processes is projected to have a positive impact on animal productivity in the future.
