Not exactly, no. They will eat the leaves off of trees, though, even if there is grass around, but they don't eat trees like it is their primary food source. The primary food source for cattle is grass in the form of hay, silage and grain.
No, but they do like to eat the leaves off of trees as far as they can reach off the ground (which can be from 5 to 7 feet high, depending on how big the cattle are). But they prefer grass to tree leaves.
No, but cows can destroy pine trees by rubbing the bark off, chewing off the twigs and branches, etc. Pine trees are actually poisonous to cattle, especially to pregnant cows.
they eat grains and other food and that makes prices go up on food also they eat other cattle food to and there droppings kill trees.
Yes. The leaves of Fraxinus spp. of trees as well as the fruits are poisonous to cattle. They won't cause instant death like death camas or water hemlock will, but it will cause dermatitis issues and eating too many leaves and fruits are more likely to cause illness in cattle, even though they like to eat the leaves.
It will eat grass and plants other cattle would rather avoid.
No, raccoons may eat fruits and nuts produced by trees but they do not eat trees.
Watusi's eat grass, just like other breeds of cattle do.
yes,but it would be harmful to the cattle.
Grass, but mostly Highland cattle eat things that cattle in America stay away from.
You can't eat trees.
It depends on the average size of the cattle. The amount of feed to feed cattle depend on their average weight and sex of cattle. Mature cows tend to eat more than weaned calves; young bulls eat more than steers, and steers tend to eat more than heifers. Older cattle eat more than younger cattle, and, thinner cattle eat more than fatter cattle. So with that, I cannot give you an accurate number.
Same thing as other breeds of cattle eat. Please see the related question below.
