Mine get Kent's http://www.kentequine.com/getdoc/708.../7678-pdf.aspx a ration balancer
I have three that get 1lb a day and one that gets 1 1/2 lbs a day
Each bag cost me $23.45 after taxes
So for 3 it is 47 cents a day
And for the other it is 70 cents a day
This does not include hay LOL
But just for giggles
A 1500 lb round cost me $40 and last about 10 days so $4 a day for hay for 4 horses :)
To get the price per lb just divide the price per bag by 50
To get the price per day multiply the price per pound by the number of pounds fed :)
OR divide the cost of the bag by the number of days it last
