This study aimed to investigate the microbial population dynamics and metabolite profiles of Ongole crossbreed cattle (OCC) fed a combination of feed additives using metagenomic and metabolomic analyses. A crossover design was employed, involving four 3-year-old fistulated OCC bulls, each receiving four distinct dietary treatments per experimental...

Silage fermentation is generally assisted by lactic acid bacteria (LAB). The aim of this study was to screen selected LABs for silage inoculant. A total of 60 LAB isolates from the Indonesian Culture Collection (InaCC) were used in this study. Screening was carried out in an MRS broth medium using three different substrates, which were glucose, suc...

The domesticated mulberry silkworm Bombyx mori L. and the wild non-mulberry silkworms are discussed in this article as potential sources of raw materials for cosmetics. Both families of silkworms produce cocoons, which are made up of the pupa and the two main proteins, fibroin and sericin. The product of the B. mori L. silkworm has the potential to...

Background and Aim Ruminant enteric methane (CH4) is one of the largest sources of greenhouse gases that contribute to global warming. To minimize environmental harm caused by ruminants’ CH4 production, natural substances can be used to suppress it. Chitosan from crustacean sources had been known to obstruct CH4 generation in the rumen. About 18% o...

Rice anaerobic fermentation is a significant source of greenhouse gas (GHG) emissions, and in order to efficiently utilize crop residue resources to reduce GHG emissions, rice straw anaerobic fermentation was regulated using lactic acid bacteria (LAB) inoculants (FG1 and TH14), grass medium (GM) to culture LAB, and Acremonim cellulolyticus (AC). Mi...

This research evaluated the effect of adding probiotic Lactiplantibacillus plantarum (P), commercial enzymes (CE), and enzyme stimulation secretion (ESS40) on in vitro fermentation. The research was conducted in two stages: selection of probiotic production media and in vitro fermentation. Increasing dextrose, lysine, and methionine levels decrease...

The utilization of polyphenol‐modified starch in ruminants has not undergone extensive exploration. This study aimed to investigate the impact of the complex formed between starch and Melastoma candidum D. Don fruit extract on physicochemical properties, phenol release kinetics in various buffers simulating the gastrointestinal tract, methane produ...

Rumen-protected methionine (RPM) is one of the ways to avoid methionine degradation in the rumen and maximize methionine absorption in the intestinal tract of ruminants. This study aims to investigate the effect of RPM added to the diets of ruminants on rumen fermentation and plasma amino acid concentration by in vivo studies using a meta-analysis...

Protein content of the substrate affects the nutritional composition of maggot ( Hermetia illucens ). This study aimed to summarize and confirm a wide range of findings about the effect of substrate protein on the nutritional composition, macrominerals, and amino acids of maggot. This meta-analysis data was acquired from papers indexed by Scopus th...

Feed safety becoming the main factor to produce good quality food. The purpose of this study was to evaluate the ability of lactic acid bacteria in degrading aflatoxin B1, suppressing the growth of contaminant bacteria, and its application on feed. Biological degradation of aflatoxin B1 (AFB1) in liquid cultures and Escherichia coli and Saccharomyc...

Background and aim: Resistant starch (RS) is difficult to digest in the digestive tract. This study aimed to evaluate the effects of heat-moisture treatment (HMT) on RS in cassava and examined its impact on rumen fermentation. Materials and methods: Cassava flour was used as a raw material and used in a randomized block design with four differen...

Silage fermentation is naturally carried out by lactic acid bacteria (LAB) to mainly produce lactic acid (LA) and other organic acids as preservatives. Along with fermentation time, the growth of LAB will replace and suppress undesirable microorganisms. This meta-analysis study aimed to explore silage microbiome differentiated by LAB inoculants and...

The absorption of the minerals produced by the probiotics in ruminants is expected to improve the absorption of the required nutrients. The study used different dietary rations with different percentage of concentrates: forages, different selenium doses, different locations and different strains of lactic acid bacteria as probiotics. The trials wer...

Extracts of Acacia and Quebracho have been used as a feed additive in ruminant diets; the effects, however, have been varied. This study used a meta‐analysis approach to evaluate the use of those extracts on nutrient utilization, performance, and methane production of ruminants. A database was developed from 37 published papers comprising 152 dieta...

Background and Aim: Lactiplantibacillus plantarum is one of the lactic acid bacteria that is often used as probiotics. This study aimed to evaluate the effects of Lactiplantibacillus plantarum TSD10 as a probiotic on rumen fermentation and microbial population in Ongole breed cattle. Materials and Methods: This study adopted an experimental crosso...

The objective of this study was to determine the characteristics of fresh rice straw silage quality prepared with addition of Lactiplantibacillus plantarum 1A-2 and crude cellulase alone or in combination. Quality of the silage was observed through the chemical composition, chemical structure and in vitro digestibility. Six treatments were used in...

Lemongrass is the raw material for lemongrass oil production. Indonesia is one of the ten largest lemongrass oil producing countries in the world. Lemongrass oil industry will be generated large amount of lemongrass waste. The aim of this study was to determine the effect of elephant grass (Pennisetum purpureum) substitution with lemongrass waste o...

Rice bran and cassava peel can be used as nutrients for yeast growth to produce mannoproteins. Currently, the application of yeast cell wall mannoproteins has only limited use in the food sector such as winemaking, stabilizers and emulsifiers in salad dressings. The functional and biological abilities of mannoproteins are influenced by their consti...

This study investigated the effect of phloroglucinol (1,3,5-trihydroxybenzene) supplementation alone on methane production, rumen fermentation profiles, and microbial population structure of mixed in vitro cultures. Treatments included a control group containing a substrate with no supplement, and substrates supplemented with 2, 4, 6, 8, or 10 mmol...

This study was conducted to investigate the effects of phloroglucinol (PHLO) and the forage:concentrate ratio (F:C) on methane (CH4) production, rumen fermentation profiles, and the microbial population in vitro. Rumen fluid was collected from male Friesland sheep using a stomach tube before the morning feeding. The treatments comprised two differe...

This study aimed to perform a meta-analysis on the effect of 3-nitrooxypropanol (3-NOP) on enteric methane (CH4) emissions from ruminants. A total of 12 in vivo studies from 10 articles were integrated into a database. Ruminant species included were dairy cows, beef cattle and sheep. Concentration of 3-NOP in diets varied from 0 to 280 mg/kg dry ma...
