Hay. Or Silage. Or Grass. Or Grain. Take your pick.
I looked through my car window and saw a young calf grazing in the grass.
No. They chew partly digested forage (like grass, hay and silage), not "spit."
To chew the grass/pasture that they eat
grasshopper
Depends on how old the calf is, but milk replacer mixed with water is what you can feed a baby calf. Also allow it access to hay or grass, grain, and water.
Dogs will be seen to eat long stranded grass when they feel nauseous. The grass somehow assists vomiting.
Grass is really hard to digest so they have to chew down the cell wall of the plant to digest it otherwise it'll come out exactly the way it was when it was eaten.
it uses its flat teeth to chew the top of the grass
They use the long incisors to nip off the grass and then the flat molars to chew it
Usually around 200 lbs.
Yes they do. They need their teeth to chew the grass that forms their staple diet.
