Evaluation of methane-utilising bacteria products as feed ingredients for monogastric animals.

Principles for the Use of Non-protein-nitrogen and 'bypass' Proteins in Diets of Ruminants

The apparent inefficiency of ruminants compared with monogastric animals in utilising protein rich feeds has been used as an argument to emphasise the importance of monogastric animals in preference to ruminants for meat production. Recent studies however (see Preston & Willis, 1970 ; flrskov, Fraser, McDonald & Smart, 1974 ; Kempton & Leng, J-976 ), have indicated that with correct balancing o...

Mitigating climate change: the role of domestic livestock.

Livestock contribute directly (i.e. as methane and nitrous oxide (N2O)) to about 9% of global anthropogenic greenhouse gas (GHG) emissions and around 3% of UK emissions. If all parts of the livestock production lifecycle are included (fossil fuels used to produce mineral fertilizers used in feed production and N2O emissions from fertilizer use; methane release from the breakdown of fertilizers ...

Removal of Excess Cellulose and Associated Polysaccharides in Fruit and Vegetable By-Products – Implication for Use in Feed for Monogastric Farm Animals

In vitro Evaluation of Different Feeds for Their Potential to Generate Methane and Change Methanogen Diversity

Optimization of the dietary formulation is the most effective way to reduce methane. Nineteen feed ingredients (brans, vegetable proteins, and grains) were evaluated for their potential to generate methane and change methanogen diversity using an in vitro ruminal fermentation technique. Feed formulations categorized into high, medium and low production based on methane production of each ingred...

Annals of Animal Science

The growing concerns of consumers on the use of antibiotic as a growth promoter in livestock feed have fueled the interest in alternative products. In the recent years a group of natural product known as phytogenic has been a focus of several studies. Phytogenics are a heterogeneous group of feed additives originating from plants and consist of herbs, spices, fruit, and other plant parts. These...
