The major ionophore in cattle feed in the United States is monensin, which has anti-protozoal properties and helps keep Giardia cysts under control.
No. Corned beef is not from cows that are fed only corn. Corned beef is beef which has been cured with salt, more specifically "corns" of salt.
They are not fed ephedrine.
Beef cattle are fed many different ways depending on how old the cow/calf is. Usually the cheap meat in stores is from dairy cows. But the best meat comes from cattle raised on alfalfa/oat mixture or cattle that are grazed on open range.
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.
Beef is usually the unhealthiest because it contains the most fat/cholesterol and ground beef can have mad cow disease from cows being fed cows.
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.
Hypothesis, since it is a statement that is being tentative about the natural world, in this case dairy cows and the response to their milking ability if they are fed wheat or not.
No. The amount of feed fed to cattle has nothing to do with change in seasons. The amount of feed fed to dairy cows is the same regardless of change in the seasons.
Bubba's Burgers down own any cows, but the beef they serve (Kauai Island Bubba's Burgers, see related link below) is indeed grass-fed.
Yes. They are fed a variety of foods to help in the production of milk or beef.
Corn-fed beef is often deemed as unhealthy, since it is high in saturated fats and low in omega-3s. Corn-fed beef is often blamed for increased obesity in people as well as heart disease and diabetes.
Beef cattle normally need just roughage to subsist. Beef cows do considerably well on just grass and hay, though some producers like to give them a taste of grain or silage or alfalfa cubes if the hay quality is poorer than necessary. Finishing beefers are typically fed a grain-based diet, though the natural-way of finishing beefers involve mostly grass and legumes. Grass-finishing is a niche market comparted to grain-finishing. Beef cattle have less nutritive requirements than dairy cows. Dairy cattle need a feed that is high in energy, protein and calcium to be able to produce good milk. Since dairy cows are quite thin, they need this feed for both bodily maintenance and lactation, as thin cows need a higher quality feed to meet maintenance needs. Grain and silage (grass, cereal grain and/or alfalfa) is the primary diet that dairy cows are fed.
