== Not being rude == 

 I wasn't being rude, just making a point, which you seem unable to accept, judging by your cowardly removal of my comments. I note that not many people seem to be as assiduous as you are about the names judging by the response to my suggestion (suggested by yourself) at Wikipedia talk:WikiProject Poultry. 
 :Wherever did you get the idea that capitalization of Livestock breed names is "invariably capitalised in Wikipedia". viz: 
 *Berkshire pig 
 *Forest Mountain pig 
 *Aylesbury duck 
 *Ancona duck 
 *Bali duck 
 *Nigerian Dwarf goat 
 *White Park cattle 
 *Friesian horse 
 *Hog Island sheep 
 *Large Black pig 

 and how about Belgian poultry breeds 

 There are many more examples on Wikipedia and elsewhere which will support me.
