What are these struts for on this cattle shed? Can they go?

[cowboy25]

I'm looking to turn this part of an old cattle shed into a workshop extension for building shepherds huts and the like, but what are these metal struts for? And can I remove them? Two of them come down quite low and would totally get in the way of what I would be making. Can I remove them? I've never seen them in this type of construction before.

Has the doorway been moved?  Looks like there is no significant lintel/support over the opening, so perhaps those struts are to stop any movement of the vertical steels around the opening.

It was just a big agricultural metal door there which I removed a few years ago, the struts predate that and were probably there on construction of the building. Only thing I can think is that this building used to house a rotary milking parlour making it a special building in that regard but I still can't understand what the struts are for or why a building built to house a rotary milking parlour would need these struts in the roof.

I would guess those struts stop the wall falling in or out.   
 

It looks like a single block wall with no visible pillars, and I think of such as being very weak.

 

The sort of gable truss that forms the top half of that wall is just sat on top.   There is no strength in the wall to stop it bulging in or out and that would result in the gable wall failing.  I think.   No doubt a grown up will be along soon to clarify.
