Abstract

This study seeks to evaluate the physico-chemical properties of tofu waste silage with the inclusion of refined rice bran and chestnut tannins as additives. This study employed an experimental method using a completely randomized design, comprising four treatments and five replications. The treatments included are T1: Fresh Tofu Waste (FTW as control), T2: FTW + 5% fine rice bran (DM basis), T3: FTW + 1% chestnut tannin (DM basis), and T4: FTW + 5% fine rice bran + 1% chestnut tannin (DM basis). The variables measured were temperature, humidity, pH, mold growth, aroma, texture, color, and dry matter loss. The data collected were analyzed using analysis of variance (ANOVA), and Duncan's multiple range test was applied at a 5% significance level to assess significant differences between treatments. The findings revealed that the inclusion of fine rice bran and chestnut tannin had a significant impact (P<0.05) on the temperature, humidity, pH, mold growth, aroma, texture, color, and dry matter loss of fresh tofu waste silage. In conclusion, the addition of 5% fine rice bran and 1% chestnut tannin resulted in tofu waste silage with superior physico-chemical quality, as evidenced by the lowest dry matter loss compared to the other treatments.

Abstract

Avocado seed meal, a part of the avocado plant that is rich in antioxidants and various other nutrients and non-nutrient substances, has great potential to be utilized as an herbal additive in animal feed. This study aims to determine the effect of molasses addition on the nutrient profile and quality of avocado seed meal silage. The control treatment (P1) used plain avocado seed flour, while the experimental treatments (P2, P3, P4, and P5) incorporated increasing molasses concentrations of 1%, 1.50%, 2%, and 2.50% of dry matter, respectively. All treatments were silaged for 30 days at room temperature. Key parameters measured were nutrient content, temperature, pH, fungal growth, physical and fresh silage quality, dry matter loss, and Fleigh value. The data obtained were analyzed based on analysis of variance, differences in parameter values between treatments were further tested with DMRT at the 5% significance level. Results indicated that molasses significantly enhanced the silage's nutrient content and improved its physical and fresh quality by optimizing temperature, reducing dry matter loss, and increasing Fleigh value (P<0.05). The conclusion of this study suggests that adding 2.50% molasses can produce the highest-quality avocado seed meal silage as an optimal herbal feed for livestock.
