Average urine production in adult humans is around 1.4 L (0.31 imp gal; 0.37 US gal) of urine per person per day with a normal range of 0.6 to 2.6 L (0.13 to 0.57 imp gal; 0.16 to 0.69 US gal) per person per day, produced in around 6 to 8 urinations per day depending on state of hydration, activity level, environmental factors, weight, and the ...
According to the Global Methane Assessment published in 2021, methane emissions from livestock (including cattle) are the largest sources of agricultural emissions worldwide [40] A single cow can make up to 99 kg of methane gas per year. [41] Ruminant livestock can produce 250 to 500 L of methane per day. [42]
A lactating cow produces about 322g of methane per day, [27] i.e. more than 117 kg per year through burping and exhalation, making commercially farmed cows a major (37%) [28] contributor to anthropogenic methane emissions, and hence to the greenhouse effect. 95% of this gas (wind) is emitted through burping.

If you need to pee a lot (or hardly ever), here's what it could mean.
According to the Global Methane Assessment published in 2021, methane emissions from livestock (including cattle) are the largest sources of agricultural emissions worldwide [10] A single cow can make up to 99 kg of methane gas per year. [11] Ruminant livestock can produce 250 to 500 L of methane per day. [12]
Concentrations of heavy metals such as lead, mercury, and cadmium, commonly found in sewage sludge, are much lower in urine. [25] Typical design values for nutrients excreted with urine are: 4 kg nitrogen per person per year, 0.36 kg phosphorus per person per year and 1.0 kg potassium per person per year.
Similarly, the number of flatus episodes per day is variable; the normal range is given as 8–20 per day. [23] The volume of flatus associated with each flatulence event again varies (5–375 mL). [ 2 ] [ 21 ] [ 24 ] The volume of the first flatulence upon waking in the morning is significantly larger than those during the day. [ 2 ]
It is a very toxic substance to tissues and extremely soluble in water. Only one nitrogen atom is removed with it. A lot of water is needed for the excretion of ammonia, about 0.5 L of water is needed per 1 g of nitrogen to maintain ammonia levels in the excretory fluid below the level in body fluids to prevent toxicity.
