In ruminants, nutrient inputs are first to fermentative digestion by ruminal microorganisms. The microbial fermentation products eventually become available as energy (volatile fatty acids) and protein (microbial cells) for animal tissue metabolism. However, ruminal fermentation also produces methane (CH4), carbon dioxide (CO2) and ammonia (NH3). Methane production in the rumen is an energetically wasteful process, since the portion of the animal’s feed, which is converted to CH4, is eructated as gas.
hello dear
i think Frayna this type of compounds suitable for the production of biogas as primary materials classified according to studies done by this study, and the waste produced Badrnzrgrftn weighing 270kg
Containing about 34% of a cow's rumen contents of the stomach and intestines, and the potential of biogas production m3 / kg TS 0/47 biogas production rate of this process more than 200 tons of waste per year is approximately equal to (4/5 × 106 m3 6 10 × 3 / 3 is estimated that the heat value of methane is equivalent to 27 / 7kWh .
i hope answer your question.
this is my Ideas of course.
Indeed its a topic of interest and discussion when there are heated discussion on environment conservation and global warming. But, as Rafael mentioned above, there are several hundreds human deeds that are causing the green house effect where mitigation approach has been mere. Besides, ruminants are an important source of animal protein and also the only source of family income in the third world countries. So, i would rather suggest looking for options like feeds which could help in capturing extra protein and energy in the form of VFA and lead to minimal wastage in the form of methane and ammonia. I worked in one of such small summer project, but still awaiting the lab results. So, yes i wouldn't take them as a problem.
Dear Mohamed,
The rumen fermentation may appear to be uneficient, but cannot forget that ruminants are able to feed resources that we are not able to eat. In this sense, they are of great value.
Moreover, we must take into account that the benefits derived from ruminants are huge:
- Environmental ones: carbon sequestration, soil fertilization, flora diversification, reduction of the risk of fires, etc.
- Economic: main activity in rural and developing/underdeveloped areas
- Social: job opportunities, the only source of proteins, etc.
The thing is: we have to know where and how to rear animals in each specific ecosystem and context (environmental, social and economic), because nothing sustainable everywhere nor everytime.

Dr. Alfredo J. Escribano.
If one uses rumen in an artificial environment, the output is then an animal based protein that has the same nutritional properties as a fish from the ocean. If you strip the lipids from the protein, then the output is close to fish meal. The lipids have the same nutritional composition as fish oil.
Ruminants are instead the way way forward. Rapid monogastric production put a lot of strain on grains especially in the developing countries as the bulk of poultry diet are dependent on grains which directly compete with humans with available feed resources. Researches have shown that ruminants in the wild emits lesser methane compared with their domesticated counterpart. Focus should instead be placed on improving pasture available to feed ruminants, incorporation of hydrogen sink in the rumen and combating methane producing archea in the rumen while continuing efforts to breed ruminants with lower methane emission is on going.
There are many problems in the ruminants, from birth to rumen development. Ruminants have a groove called esophageal, which is a stretch of the esophagus or a tube that bypasses the retina and the groin and enters directly into the paper and primary function of the groove in small ruminants to allow the milk to museum directly from the esophagus To the paper without passing through the rumen and the curriculum
Well, it depends on the perspective of discussion. With regards to greenhouse gas emission, ruminant are causing environmental pollution in the the form of methane, nitrous oxide and groundwater pollution . for the advocate of climate changes, recent research suggest that there is no practical based evidence that anthropogenic greenhouse gasses are responsible for climate change and peradventure there is, such impact is insignificant. but the real cause of climate change is attributed to lower cloud cover fraction .
However, with regards to nutrition and nutrient recycling, ruminant offers the benefit of providing essential nutrient and animal protein from non-human edible material and the manure derived from such could be turned back to the soil.
From the health aspect, there are diseases relating to consuming ruminant product, but these are associated with excess intake. Also, consuming product of pasture-fed ruminant is better than grain fed ruminant, due to the lower omega-6 to omega-3 ratio.
Ruminant animals have their usefulness in agriculture and can cause pollution.

thank you for the question , but if the researcher found a practical method to break down methane formation that will decrease the problem, in my research i read some papers shows that antioxidant decrease methane conformation in the rumen.
also antioxidant increse protein escaping to the small intestine which decrease ammonia conformation.
