Almost all hormones are, in fact, not fed to cattle. The vast majority of hormones, in their various forms, are injectable and are administered to cattle in either a capsule- or a liquid-form (particularly that of Posilac for dairy cows). Melengestrol acetate MGA is the only hormone that is administered to cattle--specifically feeder beef heifers--orally as a feed additive in order to suppress estrus activity. Estrus activity in heifers creates issues from a feeder's standpoint, as such heifers' rate of intake and gain will decrease when they are in heat, which will compromise their gaining ability and overall target weight when they are meant to be fed up for slaughter.
Depends on the ranchers themselves and what market they are targeting, and what cattle they're feeding. Cattle fed on a feedlot diet (which comprises of 97% of the finisher/backgrounding herd in the USA) are not fed hormones, but are given growth hormones via implants in the ears. Heifers, on the other hand, are fed hormones to keep them from going into heat all the time. Angus cattle on such a diet are fed primarily corn-grain-silage mixture to fatten them up prior to slaughter.
Not all farmers, no. Only those that are feeding cattle in CAFO operations (feedlot and dairy) that are raised for only beef and/or milk and in those countries that do not prohibit hormones or antibiotics being fed to cattle will be feeding cows hormones.
Corn, Corn fed cattle, Corn fed people who were fed on Corn fed cattle.
The benefits of eating grass fed beef is more than just taste. There is also a health factor to it. Typically, grass fed cattle are not fed growth hormones, or antibiotics, making them much healthier for human consumption.
No
No. Cattle can be fed other grains like barley and oats, and even more can be fed on just grass alone.
The sale of cattle that have been fattened and are ready to be butchered.
No. If grass-fed cattle got any grain, they wouldn't be grass-fed then. Grass-fed beef comes from cattle that are finished on grass only, with absolutely NO grain.
Cattle.
On a ranch per say there is really no particular shelter were cattle need to be fed. Cattle can be fed out in the open in the corrals or pastures. I think you are thinking of those black-and-white dairy cows that are commonly fed in barns.
Corn, barley, oats, etc., same grain fed to cattle.
It depends on the location, and the type or class of animals fed. There can be as little as no corn (0%) in a feed ration for cattle, or as much as 85% in a feed ration. Not all areas in the world can or will grow corn, and not all feed fed to cattle includes corn. For instance, much of the grain fed to cattle in Canada is barley or oats, not corn.
