Okay, as an individual from an agricultural area, I tend to get really nit-picky about how livestock is represented in media. So it’s always bothered me that Batcow (or Bat-Cow) has been identified at least once as a Jersey cow.
Here’s a picture of Batcow.
And here’s a Jersey cow.
The breed is typically solid brown, with lighter coloring on the legs and face, but no white patches. Sure, Batcow could be a mix breed of a Jersey and Holstein (below), as that would have given her her white patches.
However, Holsteins are a tall breed and Batcow is a relatively short cow. See how she compares to Jon and Damian.
Also, both Holsteins and Jerseys are dairy breeds, so it’s highly unlikely that she would have been in a slaughterhouse if she was indeed a Jersey or Jersey/Holstein mix, especially since she appears to be a rather young cow. Beef cattle are sent to slaughter. Also, neither Holsteins nor Jerseys have horns.
Of course, Batcow can also be found with this red-and-white coloring, as seen below.
Also, she has a brand on her hip, which is typically used on beef cattle rather than dairy cattle. My best guess is that Batcow is actually one of these!
Hereford cows! A small, beef breed with red-and-white coloring. The white on the underbelly and face matches Batcow, and Herefords can have red facial markings. Also, Herefords carry the genetics for small horns and furry topknots on the tops of their heads, all traits exhibited by Batcow. I know Batcow is mostly white-and-brown in current comics, but Herefords range from dark red to light red, so I’m still sticking to the thought that Batcow is a very light red-brown Hereford. Also, Herefords are a very gentle breed known to recognize their owners, and Batcow certainly loves her cuddles and her Damian.
So there’s my PSA, discussing what breed of cow Batcow actually is.
