As a longhorn breeder, I found it to be an excellent article in many ways.
They not only have smaller calves, and are good mothers - they are also loaded with personality. "Longhorn Breeders pull trailers, not calves" is very true. Commercial breeders might consider that more stronly for their first time heifers.
Lonhorns (registered) are not cheap animals, and as far as feed goes, well, what you feed is what you get. The beef is lower in cholesterol, leaner, and requires less cooking time. If you are into cattle, I recommend you try a longhorn on your cows.
