Depends on what you're looking for in the meat.
First of all, the facts that your bovine is a steer and is of the black angus breed are practically irrelevant. Most any breed of beef cattle and both sexes will butcher similarly given similar conditions of development.
Typically cattle are butchered when they are nearing nine months to sixteen months of age. This is the time frame when they are nearing or reaching their full size. Allowing meat cattle to go beyond this time frame will most likely result in tougher, more stringy meat (aka meat of poorer quality). However, the time frame in which you butcher your animal can depend largely on if they have reached the size and fat content that you desire. My family always butchered our steers and heifers around nine to ten months of age.
If by "when" you mean what time of year, then that is a silly question. I guess that all depends on when you want the meat, how long you want it to last, and when your steer reaches the right age range/weight.
A yearling Angus steer should weigh around 800 lbs.
A good Angus steer, especially if you are choosing a steer for 4H or FFA, must have good conformation, good average daily gain (preferably 2 lbs per day or more) and good feed intake. You can choose your steer from a local cattle producer that raises Black Angus cattle to find a good steer to raise for the show circuit. The cattle producer will help you find the best steer for you as well.
Usually it is better to butcher a beef steer but heifers are okay.
Absolutely not! Angus is a breed, which encompasses not just steers, but also cows, bulls, heifers and calves of the same breed. The Angus breed are black polled cattle that originated from Scotland and is the breed that has gained huge popularity in the United States.
I believe angus is best for meat.
A steer typically weighs around 1300 lbs at slaughter. Cows, on the other hand, can be any weight, depending on their frame size.
Yes, they can. Just remember that a Holstein steer's nutritional needs may be a bit more higher than an Angus yearling's.
There really is no difference between Angus beef and "regular" beef. Pure Angus beef may have a bit more marbling to it and be a bit more tender, juicy, and (to some) be more bland than "regular" beef, but in reality, a Shorthorn or Speckle Park steer will often have the same sort of marbling quality. Because when the hide comes off, they all look the same.
It all depends on what feed is being fed to that steer, as in what feed is available, what the ratio of forage to grain is for that steer, and the steer's breeding and genetics. Some breeds or crossbreeds of steers will require less feed to achieve a pound of gain than other breeds or crossbreeds. For instance, an Angus steer will gain a pound on less feed than a Simmental steer.
The average hanging weight of a 20-month-old Hereford Angus steer typically ranges from 600 to 800 pounds. Factors such as diet, genetics, and overall health can influence this weight. Generally, beef cattle at this age are well-developed, contributing to a substantial hanging weight when processed.
A mature Angus beef typically weighs between 450 to 1,100 kilograms (about 1,000 to 2,400 pounds). The weight can vary based on factors such as age, diet, and genetics. On average, a finished Angus steer ready for market is often around 600 to 800 kilograms.
For such a general question, it requires a general answer: It depends on the steer and the type of feed corn being used to feed that steer. There is some sort of general "rule of thumb" out there that it takes around 9 lbs of grain to get one pound of beef, but that is pretty ambiguous. It takes more pounds of corn to get a pound of gain on a Holstein steer than it would on an Angus steer, for instance. Also, cracked corn will get a steer to gain more weight than whole corn will.
