Aug 23, 2021 · Compared with low-concentrate diets, high-concentrate diets can be rapidly fermented by ruminal microorganisms to produce short-chain fatty acids (SCFAs), especially propionate and butyrate,

Fermented feed: Improve animal performance, ingredients

Mar 26, 2021 · Fermented feed and pig performance. Fermented feed ingredients include protein sources and energy sources. Fermentation improves protein digestibility, increasing the number of small peptides, decreasing larger-sized peptides, and improving amino acid availability.

A Review of Effect of Saponins on Ruminal Fermentation

Jul 10, 2023 · Saponins are steroid, or triterpene glycoside, compounds found in plants and plant products, mainly legumes. However, some plants containing saponins are toxic. Saponins have both positive and negative roles in animal nutrition. Saponins have been shown to act as membrane-permeabilizing, immunostimulant, hypocholesterolaemic, and defaunating agents in the rumen for the manipulation of ruminal

Advances in Pasture Management and Animal Nutrition to

Jul 24, 2021 · The increasing demand of meat requires the adoption of sustainable intensification livestock systems, applying nutritional strategies to reduce any negative contribution from beef cattle to global warming and, at the same time, to increase animal performance and productive efficiency. The pasture management practices and feed supplementation, mainly using non-edible feed with less costs, could

Management of Enteric Methane Emissions in Ruminants Using

Dec 7, 2022 · Given the high amount of CH 4 emissions from enteric fermentation, particularly cattle but also other species, the commercialization of feed additives alongside farmer training, can be a very good approach to curb emissions. One can compare reduced enteric methane emissions to energy efficiency gains in other sectors.

Effects of Exogenous Biochar Addition on High - IOPscience

Aug 22, 2021 · In order to explore the effects of adding biochar on biogas production by high solid concentration anaerobic fermentation of livestock and poultry manure and agricultural safety, this study used pig manure, cow manure and chicken manure as fermentation raw materials, and carried out experiments on biogas production by mesophilic temperature anaerobic fermentation with high solid concentration.

Process optimization and feature analysis of an anaerobic

Dec 30, 2021 · Fermentation temperature, total solid (TS) concentration, and mechanical stirring are important factors affecting anaerobic digestion. Medium and high temperatures can promote anaerobic digestion processes, but to ensure the reaction temperature of the material in engineering applications, the energy consumed will also be increased [Citation 5

Mechanism of action, benefits, and research gap in fermented

Mar 1, 2024 · This review details the mechanism of SBM fermentation and its impacts on animal health and discusses the recent trend in the application and emerging advantages to livestock while shedding light on the research gap that needs to be critically addressed in future studies.

Diversity and dynamics of the bacterial community involved in

Jun 3, 2017 · Overproduction of livestock manures with unpleasant odors causes significant environmental problems. The microbial fermentation bed (MFB) system is considered an effective approach to recycling utilization of agricultural byproducts and pig manure (PM). To gain a better understanding of bacterial communities present during the degradation of PM in MFB, the PM bacterial community was evaluated

Frontiers | Metabolic Hydrogen Flows in Rumen Fermentation

Adding a hydrogenotroph with a high V max for H 2 can allow a high flow of H 2 incorporation into a desirable fermentation product. However, if the K m of the added hydrogenotroph for H 2 were high, H 2 would still accumulate, and the magnitude of gaseous H 2 losses could be important.

Fermentation | Free Full-Text | Effects of Different Soybean

Dec 1, 2022 · Soybean (Glycine max Merr.), with a high nutritional value, is an important oil crop and a good protein feed crop. Due to the shortage of high-protein feed and the high import pressure on soybean, scarce high-protein feed is the main research target for improving feed quality. High-quality soybean (Qihuang 34) and high-yield silage maize (Zea mays L.) (Jingling silage 386) varieties were used

Responses of nutrient utilization, rumen fermentation and

May 29, 2024 · Dairy buffaloes are typically fed a high-forage, low-quality diet with high fiber. These conditions result in an inherent energy and protein inefficiency. In order to make full and rational use of feed resources and improve the production level and breeding efficiency of dairy buffaloes, the effects of various roughages on nutrient digestibility, ruminal fermentation parameters, and

Microbial composition, rumen fermentation parameters, enteric

Jul 19, 2023 · This experiment was designed to investigate the relation of high and low methane-yield phenotypes with body weight (BW), dry matter intake (DMI), lactation performance, enteric CH4 emissions, and rumen fermentation parameters in lactating dairy cows. A total of 130 multi- and primiparous Holstein cows were screened for enteric CH4 emissions using the GreenFeed system (C-Lock Inc.). Out of

Whole-plant corn silage improves rumen fermentation and

Ruminococcus_2 was positively correlated with amino acid metabolism and carbohydrate metabolism. Feeding whole-plant corn silage can improve the growth performance and rumen fermentation of beef cattle by altering rumen microbiota and regulating the metabolism of amino acids, carbohydrates, and nucleotides.

Dietary manipulation: a sustainable way to mitigate methane

Jun 18, 2018 · Methane emission from the enteric fermentation of ruminant livestock is a main source of greenhouse gas (GHG) emission and a major concern for global warming. Methane emission is also associated with dietary energy lose; hence, reduce feed efficiency.
