No, however they do damage fences which can cause problems for farmers as the farm animals can escape
1) Animals treated with antibiotics get fatter quicker because theyaren'twasting any energy on fighting diseases.2) Animals treated with antibiotics wouldn't infect other animals or workers or people who ate them.
You cannot compare raising crops with raising animals. They are two separate things, but the way animals are raised today is most likely cheaper than raising animals the way small farmers raise them. On a small farm, animals have fields they can graze, are not usually given any hormones, and the use of antibiotics is rare, but in what is called "factory farms" animals are raised in buildings under very crowded conditions. Many of these animals are given hormones or are genetically modified to grow faster, and are given antibiotics to ward of disease. It is likely that using the factory farm method is cheaper than allowing them room to graze and not using hormones to cause them to produce more or to grow faster.
Cows cause "enviornmental problems" because the "fart" or "poot" "toot" or Fart. PU!!!!
Cows and chickens are farm animals. Additional farm animals include calf and colt.
only when they are sick
the difference is you wont find most farm animals in a zoo and farm animals tend to bbe smarter.
No. Marsupials are not predators of farm animals.
no, farm animals are sheep and cows
They don't...lack of illness allows animals to maintain a steady growth rate. Proper selection for fast growth rate in a breeding program increase growth rate. The idea in a feeding program is to maintain steady growth through proper nutrition, minimum stress and a clean (not germ free environment). Constant feeding of antibiotics is generally detrimental as it kills gut flora, which is responsible for a large portion of digestion in farm animals
The classification of farm animals can indeed be based on their uses. Farm animals can be classified as product producers.
Not all farmed shrimp has antibiotics and hormones, but most farmed shrimp from Asia do.
