20% AN Wrangler Cake w/Vitamin A is our most popular winter protein supplement for range cattle. Wrangler Cake is an economical, natural protein supplement for use in beef herds that are offered year-around mineral and vitamin supplement programs. Feed daily to cattle maintained on medium-quality winter range (7-9% CP) that need a small boost in protein and energy. Wrangler Cake can also be fed to goats and sheep. There is no vitamin or mineral fortification added to this cake formula (other than a low level of Vitamin A), therefore a mineral program is necessary.
