Depends on several factors: how the legumes are fed, moisture content of the feed, body weight of the cow, etc.
On a rainny day they eat grass.
None. Cows don't eat money.
they eat walk a little bit and sleep that what cows do
Yes. A lot of the legume plants that they eat have flowers--clover, alfalfa, sanfoin, etc--thus it isn't all that uncommon for a cow to eat a bunch of flowers in addition to the grass they graze.
Cows tend to eat the most during the morning and evening hours, as well as throughout the day.
Cattle can eat during all hours of the night and day, since they only sleep a few hours during the day at a time. If the day is hot, they will stay in the shade and only graze during the cool in the morning and evening. If it is cold out, they will eat as much as they will to keep themselves warm then rest and ruminate. Cows that are fed in a barn like most dairy cows will eat when they are fed, pausing to rest and ruminate, then eat again. All cattle are fed ad lib so they eat as much as they want before laying down to chew their cud.
Cows, like all animals, do not eat water, they drink it. And cattle typically consume around 10% of their body weight in water per day.
This is common misconception that you have started to believe. Cows and cattle do not eat 24 hours a day. They only eat around 16 to 18 hours per day, and spend the rest of the time resting to chew their cud, socializing with other cattle, getting milked (only if they're dairy cows), traveling back and forth to watering holes, etc. Cattle can only eat so much before they're stomachs get full.
eat grass and sleep they are not fun
