How do you fatten your beef cattle?

Fattening beef cattle depends on what diet you want them to fatten up on, their age, their breeding, average daily gain, rate of intake, and target weight you want to have them slaughtered. Grass-finished cattle take a month or so longer to fatten up than grain-finished cattle. But both types of finisher cattle should be on a high-energy, high-protein diet to gain weight quickly. For grassers this would be young, vegetative grasses that are almost at the stage of inflourescence but the long stems that haven't quite popped up yet. It will take about 6 months for the cattle to reach target weight. For grainers, a diet of 80 to 90% diet of grain is the common way (the feedlot way) to fatten cattle within a period of 3 to 4 months. However, if you wish you could finish your cattle on a 50-50 or 40-60 diet of grain and forage, respectively or vice versa, to get a stronger tasting, yet juicy steak.

British breeds fatten quicker than Continentals will. So starting British breed-type cattle when they are but 18 to 20 months of age on a high energy ration will get them to gain enough meat on them but not too much fat. Continentals genetically are built to be lean, so you could start them whenever you like, like right after they are weaned on a grain-based diet or a diet of 50% forage 50% grain to get them to gain weight. Continentals will finish at a heavier weight than British breeds will, so also bear that in mind when choosing which breeds to fatten up for your freezer. Crossbred calves that have British and Continental breeds in them can be started either way, but the British influence will have them still fatten quicker, so backgrounding them until they are 18 months old would be a wise decision.
