I'm looking for suggestions on what to feed my 3 year old Standardbred mare. She is worked for a 1/2 hour to a full hour 5 days a week on the lunge line to strengthen her muscles. She is currently on 1 qt of beet pulp (shredded and soaked) as well as 1 cup of oats and a 1/4 cup of canola oil. However, I'm worried this is not enough to keep weight on her while she's being worked on a daily basis. Keep in mind (not sure if this site has US posters) that I am in Ontario and may not be able to get some of the US branded feeds. Any suggestions would help, don't want her to start losing weight before show season!
