Mixed Leucaena and molasses can increase the nutritional quality and rumen degradation of corn stover silage

Abstract

Objective: The study was conducted to determine the effect of Leucaena at different proportions and doses of molasses on the nutritional quality, silage fermentation characteristic, and in vitro digestibility of corn stover silage. Materials and Methods: The study was designed in a completely randomized factorial design 3*3 pattern. The first factor was the proportion addition of Leucaena, i.e., L0 (0%), L15 (15%), L30 (30%), and L45 (45%) of inclusion of Leucaena on the dry matter (DM) basis of corn stover. The second factor was the dose of inclusion of molasses, i.e., M2 (2%), M4 (4%), and M6 (6%) on the fed basis of silage. Each treatment had five replications. The variables observed included chemical composition [DM, organic matter (OM), crude protein (CP), crude fiber (CF), hemicellulose, acid detergent fiber, and neutral detergent fiber], silage fermentation characteristics (pH and NH3-N), DM digestibility (DMD), and OM digestibility (OMD) under in vitro conditions. Results: The result shows that the inclusion of Leucaena in the proportion of 30%–45% is very effective in increasing and improving the chemical composition of corn stover silage, significantly suppresses the content of CF, and increases the CP content of the silage. Likewise, the inclusion of molasses at a dose of 4% also positively contributed to the quality of the resulting silage, especially its effect in suppressing the buffer capacity of proteins resulting in low pH values and NH3-N concentrations in silage. Conclusions: It was concluded that the inclusion of Leucaena in 30%–45% and the inclusion of molasses at a dose of 4% is very effective in increasing and improving the chemical composition, silage fermentability characteristics, and rumen degradation of corn stover silage.

Meta-analysis of the relationship between dietary starch intake and enteric methane emissions in cattle from in vivo experiments

“…This means that other nutrients present in the diet might have influenced the degradability of starch in the rumen. Sutaryono et al [ 96 ] reported that the inclusion of Leucaena in corn stover silage affected DMD and OMD in the in vitro study. This is due to the fact that cellulose is more resistant to digestion compared to starches [ 97 ].…”

“…tarramba) has the advantage of being resistant to psyllid bug pest and resistant to dry seasons (Y. Sutaryono et al, 2023).…”

“…They know that giving lamtoro feed plants can accelerate the growth of cows compared to grass feed, so the average breeder on the island of Sumbawa uses lamtoro as a basis for cattle feed . Sutaryono et al (2023) states that the ideal botanical composition consists of 60% grass and 40% legumes, further Tahuk et al (2021) explained that legumes have a very important role in the use of feed as the main source of forage for livestock, because it can increase the nutritional value of the forage given. Thus the quality of crops/feed for cattle on Sumbawa Island is high, because the type of feed that dominates the total proportion of legumes, namely lamtoro is 46.16%.…”

Effects of kinds of additives on fermentation quality, nutrient content, aerobic stability, and microbial community of the mixed silage of king grass and rice straw

“…Fermentation inhibitors are a category of additives that serve to enhance acidity, lower the pH of silage, and impede the proliferation of undesirable microorganisms, commonly including inorganic substances (aldehydes, salts and acid–base substances) and organic acids (formic acid, acetic acid, citric acid, malic acid) ( Queiroz et al, 2018 ). Research showed that the addition of molasses improved the fermentation quality of silage and reduced the breakdown of protein ( Sutaryono et al, 2023 ). Sorbic acid addition significantly improved fermentation quality and aerobic stability of rice straw silage, slowing down the reduction of lactic and acetic acids content as well as the growth of yeasts and aerobic bacteria under aerobic exposure ( Zhao et al, 2021 ).…”
