“…A high negative relationship between fiber and digestibility may be found in forage, but not in soybeans. Previous studies reported that high fiber fraction will reduce the digestibility of the feed (Wahyono et al, 2019(Wahyono et al, , 2021. In present study, EE was negatively correlated with IVDMD.…”

“…NDF content represents most of the cell wall/fiber of soybeans seeds (Van Eys, 2015), while ADF content consists of primary lignocellulose structure and is resistant to microbial fermentation in the rumen . NDF levels have a negative correlation with feed intake, while ADF has a negative correlation with digestibility values of feedstuffs (Wahyono et al, 2021). The mean NDF content (19.97 %) of the soybean genotypes was higher than that reported in other literature (Dei, 2011;Ishler and Varga, 2015;Van Eys, 2015).…”

This work investigates the effects of different soil pH and different genotypes on the nutrient profiles and in vitro digestibility of soybeans. Thirty soybean genotypes were evaluated for nutrient composition, fiber content, and in vitro digestibility after cultivation in pH 4.0 and 5.4 soils. The experiment was arranged factorially in a completely randomized block design. The experimental factors were soybean genotype and soil pH. Results showed significant (p < 0.001) differences in fiber content, non-fiber carbohydrate content, and in vitro dry matter digestibility (IVDMD) parameters among studied genotypes. There were significant differences (p < 0.05) between the two soil pH conditions for ash, organic matter, ether extract, neutral detergent fiber, acid detergent fiber, hemicellulose, and nonfiber carbohydrate. Organic matter, crude protein, ether extract, and non-fiber carbohydrate content in soil with pH 5.4

“…Rumen liquor (400 mL) and buffer solutions (1200 mL) were mixed into each digestion jar and incubated at 39 o C for 48 h. After incubation, bags were rinsed in tap water and dried at 105 o C for 12 h. Samples were analyzed for NDF using fibre analyzer ANKOM A200 (Ankom Technology Corp, Fairport, NY, USA). In vitro true digestibility (IVTD) was calculated using the equation previously reported by Wahyono et al (2021), as follows:…”

The objective of this study was to evaluate the yield, nutrient profile and in vitro digestibility of new BMR mutant lines of sorghum in Indonesia. These mutant lines were GH2.1, GH2.2, GH2.3, GH4.1, GH4.2, GH4.3 and GH4.4. One sorghum mutant line (CTY) and two national sorghum varieties (Super 1 and Bioguma) were also evaluated as controls. In vitro digestibility and rumen fermentation were measured using Ankom Daisy Fermenter and Hohenheim gas test methods, respectively. In vitro measurement consisted of ten treatments with five replications following a completely randomized design. The highest stem sugar content was found in Bioguma (11.22%) and GH4.4 (9.32%) (p<0.05). The Bioguma variety and the GH2.3 mutant line had a higher number of stem segments and fresh forage yield than the Super 1 variety (p<0.05). A greater concentration of crude protein (CP) was observed for the GH.2.1, GH2.2, GH2.3 and GH4.1 lines (p<0.05). The GH2.3 mutant line had the lowest acid detergent lignin (ADL) content (p<0.05), while Bioguma had the highest level of non-fibre carbohydrate (NFC) compounds (p<0.05). The highest relative feed value (RFV) was observed for the GH2.3 line (p<0.05). Furthermore, GH4.2 and GH2.3 had greater in vitro true digestibility (IVTD) (p<0.05) but were not significantly different from Bioguma. Regarding yield characteristics, nutrient composition and in vitro digestibility values, the highest values were found in the Bioguma variety and the GH2.3 mutant line. Except for n-valerate (nC5), significant differences in all rumen fermentation parameters were observed among sorghum cultivars (p<0.05). Regarding the interrelationship between parameters, we found a medium correlation of DMD with the ADL and cellulose content of sorghum forage (R 2 = -0.489 and R 2 = -0.674, respectively). Based on these findings, the GH2.3 BMR mutant line should be further developed as forage sorghum.

“…As reported in rice straw and palm oil leaves, agricultural and plantation by-products have low nutrient compounds and high fibre contents.

About 25% of the anthropogenic methane emissions are due to ruminal fermentation from ruminant livestock. Green medicated supplement (Green MS) is a prototype herb and slow-release urea-based supplement to reduce methane emissions from livestock. This experiment aimed to evaluate the methane emission and digestibility of forage-based rations supplemented with Green MS. This study examines six forages (palm oil leaves, rice straw, Napier grass, sugarcane leaves, native grass and maize straw). That six forages were supplemented with Green MS. The total treatments were 12, with four replications. A completely randomized design was applied in this study. Besides native grass, Green MS can reduce in vitro enteric methane by 0.23 - 3.05 ml/200 mg DM (P < 0.05). However, Green MS did not change the value of all forage’s optimum gas production (a+b). It is interesting to note that gas production from non-soluble fibre (GPNSF) could be enhanced with Green MS in maize straw and native grass (P < 0.05). The response to supplements varies depending on the utilization of the feed substrate in incubation. In conclusion, without affecting feed digestibility, Green MS supplementation could lower enteric methane emissions.
