Methane from anaerobic fermentation in the rumen of cattle is a major contributor to greenhouse gases (50-60%). Methanogenesis is an important process in the ruminants as it scavenges hydrogen produced during the anaerobic fermentation of sugars in the rumen and, thereby, balances the fermentation...

The article reflects data on the positive effect of organic manganese on methanogenesis and metabolic processes in the rumen of bulls. It was found that the introduction of manganese at a dose of 4,0 g per 1 kg of dry matter in a sample with bran to a greater extent reduced the production of metha...

For determining the efficiency of forage combinations with varying tannin levels in small ruminants, an experiment was conducted on 36 finisher Malpura lambs. Animals were divided into 3 groups (T₁, T₂ and T₃) of 12 each and fed ad libitum complete feed blocks consisting 65, 30 and 5 parts...

The Southern Africa Development Community (SADC) region is not a major emitter of greenhouse gases (GHG). However, Sub-Saharan Africa is considered a potential future hotspot for GHG emissions because of its large livestock population dispersed across large arid lands, coupled with the inherent low ...

This issue contains 25 papers on in vitro ruminal fermentation and production of AGVS, methane and carbon dioxide with the inclusion of plant extracts from the semi-desert of Zacatecas, Mexico; the use of amino acids in the dairy industry; use of feed additives to improve feed efficiency and growth ...

Methane is an extremely potent yet short-lived greenhouse gas and is thus recognized as a promising target for rapid climate change mitigation. About 35% of anthropogenic methane emissions are associated with livestock production, and most of these emissions are the outcome of enteric fermentation...

Methanogenesis in ruminants contributes to both greenhouse gas emissions and feed energy losses whereby the latter becomes specifically important in energy-deficient periparturient cows. It was hypothesized that increased concentrate feed proportions (CFP) and feeding with the methane inhibitor...

Introduction: Pastures provide an important part of ruminant fodder needs, and farmers store some pasture plants to use in winter-feeding of livestock. Therefore, having enough information about the nutritional value of such plants can help to optimize their consumption in animal feeding....

The inclusion of plant extracts that contain secondary compounds with the potential to modulate rumen fermentation and improve animal performance has gained attention in recent years. The aim of this study was to evaluate the effect of the inclusion of yerba mate extract (Ilex paraguariensis ST....

Methane (CH₄) emission from enteric fermentation of ruminant livestock is a source of greenhouse gases (GHG) and has become a significant concern for global warming. Enteric methane emission is also associated with poor feed efficiency. Therefore, research has focused on identifying dietary...
