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

Crested macaque (Macaca nigra), one of the seven endemic primates in Sulawesi is the most endangered macaque species that has been categorized as critically endangered by International Union for Conservation of Nature (IUCN). However, almost nothing is known about the reproductive biology in associated with the behavioral during pregnancy. The data is important to support a management and breeding programs such as pregnancy diagnostic and conservation program in this species. The research aimed was to study the behavior of the crested macaques during pregnancy. Observations were performed on the 10 adult females of the group of Rambo 1 (R1) which has been habituated at Tangkoko-Batuangus Nature Reserve, North Sulawesi. Behavioral data were collected using focal animal sampling and recorded using instantanaeous sampling on females during menstrual cycling, pregnancy, and after parturition (lactation). During five months observations, a total of 393.63 observation hours were recorded. The results showed that daily activities of the M. nigra during menstrual cycling were dominated by feeding (26.60%), foraging (15.95%), and locomotion (16.16%). Daily activities during pregnancy was dominated by feeding (27.03%), foraging (16.37%), and resting (13.45%), whereas after parturition (lactation) period is dominated by resting (26.12%), foraging (19.51%), and feeding (14.98%). The resting was the most activity in the end of pregnancy and few day after parturition. The diets were collected successfully composed of the fruits (34 species), arthropods (3 species, 2 families, 4 orders), fungi (4 genus), and plants (5 species). Climate was influenced on the composition of the diet, especially on fruit and arthropods. In conclusion, the activity budgets were different during menstrual cycling, pregnancy, and lactation, especially feeding, foraging, locomotion, and resting.

Abstract

Elephant grass is a common forage for livestock fodder, yet it is prone to damage and requires preservation through silage-making techniques. This study was investigating the potential usage of expired commercial syrup (ECS) as a source of glucose in elephant grass silage production. The research used a Completely Randomized Design with five treatments and five replications. Treatments included a control group that consist of elephant grass (P1/control), and four supplemented grasses with ECS at levels of 2.50% (P2), 5% (P3), 7.50% (P4), and 10% (P5) based on dry matter (DM). After ensiling for 30 days at room temperature, various parameters were measured, i.e. aroma, texture, color, fungal growth, pH, dry matter, dry matter loss (DML), and fleigh value. Data were analysis using analysis of variance, followed by Duncan's test. The results revealed that ECS incorporation up to 10% DM had a significant influence on the evaluated parameters (p<0,05). The results showed P5 received the highest ratings from panellists for aroma (3.75; distinctive fermented acidity), texture (3.61; fine and non-clumping), and color (3.54; green). Additionally, P5 exhibited minimal fungal growth (1.57%), an optimal pH range (3.24-4.56), the highest dry matter content (31.4%), the lowest dry matter loss (2.27%), and the highest fleigh value (138). The research concluded that expired commercial syrup could use as a stimulant additive in elephant grass ensiling, effectively.
