Feed advice

[Dizzydancer]

My mare is starting to build some nice
Top line now however I feel she may need some extra help to allow this muscle development.
Currently fed half scoop mollichaff calmer, and a scoop of spillers lite balancer. With joint supplemet and a calmer. 2x large haylage nets a night.
She is a hot, stressy horse who is allergic to alfalfa, bonus she is a good doer but any suggestions as to any feed or supplement which may help muscle development (along with correct work) but isn't going to make her unrideable/manageable. Weight wise she is spot on at present.
Thanks in advance!

If you would like to help muscle grow but not put weight on then maybe swap the light balancer to a performance balancer for higher levels of protein without calories.

Thanks firewall I will have a look around the balancers and see what we will work best!
