| 4-5% larger? That's not much. So your 200 Kg cow is now 210? I'm not sure that can be directly linked to antibiotics. Maybe they were eating different food, or maybe they were given more of it? Who knows why? | |

This percentage may not be much in terms of actual cow weight... but economically the savings in production are HUGE. These pleiotropic effects are actually well documented and indeed biologists can only speculate why this occurs but it's quite a good guess that it is related to the gut flora reaching an optimal balance to allow for efficient use of cellulose (microbes in the ruminant digestive tract are symbionts, without them cows would not be able to digest feed properly).

Problem is in CH you have a higher probability of being turned into veal before you reach those teenage years
