چکیده

Ruminant animals play an important role in the food chain for evaluate cellulose and non-protein nitrogenous (NPN) compounds absorbed partially or not by other farm animals and humans. However, ruminant animals also bring some disadvantages. Methane, produced as a natural consequence of the ruminal digestion and it is a potential green house gas, is a problem, both ecologically and economically. Methane emissions from ruminant livestock are a contributor to total global anthropogenic emissions of greenhouse gases which have a global warming potential. Also methane produced by ruminants represents a loss of energy for ruminants. Methane is formed in the fore-stomach (reticulorumen, more commonly known as the rumen) of ruminants by a group of microbes called methanogens, which form a subgroup of the domain Archaea. Their effect on producing methane is mentioned. In this review, current approaches towards mitigation of methane in pastoral farming are summarised. The strategies to diminish methane output from livestock are required for ecological and economical dairy production. Research strategies based on vaccination, enzyme inhibitors, phage, homoacetogens, feed supplements, and animal selection are reviewed. Numerous studies have been completed on use of plant secondary metabolites (PSM) in substitute for chemical feed additives because some of them modify rumen fermentation and reduce CH4 production. Also this review describes the basic conceptual aspects of ruminal methanogenesis, which is a way of keeping a low H2 pressure in the rumen by reducing CO2, and steps where it may be possible to intervene to reduce CH4 production

Nutritional strategies to mitigate greenhouse gases emission from livestock agriculture: a review

Received: 11/11/2013 Revised: 13/12/2013 Accepted: 15/12/2013 Abstract Methane is the second key greenhouse gas (GHG) and enteric fermentation in livestock is one of the largest sources of methane emission, producing 15-20 % of the total anthropogenic methane. Methane production by enteric fermentation in the rumen accounts for the 2-12% loss of gross energy and consequently influence performan...

The Effects of Use Medicinal Plants on Rumen Fermentation Parameters in Ruminants

Rumen is a persistent and specific ecosystem consists of bacteria, protozoa and fungus where feed fermentation takes place in it. Produced Hydrogen in rumen can be used in the synthesis of the volatile fatty acids and the microbial protein and its excess would be eliminated through the production of Methane by methanogenesis. Nutritionists have tried to find ways to decrease loss and energy and...

Global Climate Change: Role of Livestock

Climate change is seen as a major threat to the survival of many species, ecosystems and the sustainability of livestock production systems in many parts of the world. Green house gases (GHG) are released in the atmosphere both by natural sources and anthropogenic (human related) activities. An attempt has been made in this article to understand the contribution of ruminant livestock to climate...

How Enteric Methane is Produced by Cattle

About 3 to 12% of the energy consumed by ruminants (cattle and sheep) is converted to methane in the rumen (referred to as enteric methane) and released into the atmosphere. Adopting feeding strategies that will minimize the amount of energy, lost as methane, can improve feed conversion efficiency, improve animal productivity, and is good for the environment. Producers can reduce their herd's m...
