I have lived on a Commercial ( mixed breed) Beef Farm my whole life and can dispute a few myths here:
Any Breed when selected for a trait like muscling, easy of fleshing, carcass size, mothering..ect over time will can/ will be as good as the other breeds.
All Cattle are the same color underneath when you remove their coat.
Angus are not the End All Be ALL of Beef Cattle ~ The Breed Association was very smart on their breed promotion. (Although they do posses a lot of great trait). There are many other breeds of cattle that have been selected for generations for Beef traits. We have a herd with influence from many breeds... Simmental, Charolais, Gelbvieh, Shorthorn, Belted Galloway, Angus, Hereford, Jersey... lol and lots more. Over the years we have selected for meat and carcass traits. And let the results weigh on the herd selection.
Can anyone here tell what breed of chicken they are eating when they are plucked, cleaned and cooked...
I think if you are going to start raising your own beef and breeding them you have a few questions to ask yourself.
What like of feeding program are you planning to raise the beef animals on? Grass, Hay and Grain...
What are your facilities like? Barn / Corrals ...
What time of the year are you planning to calve.
What traits are the most important to you? Temperament, Size, Ease of Fleshing...
How much land do you have to raise your herd?
Also Dairy Breeds are very edible too. The down sides are they are built to have narrow frames, slow maturing and tend to take a lot longer to be finished to butcher.
