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.

Abstract

This study was conducted to evaluate the effect of different levels of mangosteen peel meal (Garcinia mangostana Linn.) supplementation in commercial rations on feed consumption, body weight gain, and feed conversion ratio of broiler chickens. A total of 100 broiler chicks aged 8 days with uniform body weight were randomly assigned to four dietary treatments with five replications, each consisting of five birds. The treatments were: T1 (control, commercial ration without mangosteen peel meal), T2 (commercial ration + 2.50% mangosteen peel meal), T3 (commercial ration + 3% mangosteen peel meal), and T4 (commercial ration + 3.50% mangosteen peel meal). The experiment was conducted using a Completely Randomized Design (CRD). Data were analyzed using analysis of variance (ANOVA) and Duncan's multiple range test. The results showed that supplementation of mangosteen peel meal up to 3.50% did not significantly affect (P>0.05) feed consumption, body weight gain, and feed conversion ratio of broilers. The average feed consumption ranged from 603 to 640 g/bird, body weight gain ranged from 296 to 310 g/bird, and feed conversion ratio ranged from 1.99 to 2.17. It was concluded that mangosteen peel meal supplementation up to 3.50% in commercial rations did not improve the production performance of broilers.
