Primo 18 QuickStart is a multi-use show feed formulated for hard muscled late nursery pigs to soften and help their leg structure loosen. Primarily a go-to for incoming purchased pigs over 45 lb of body weight for proper muscle and body shape as pigs develop but is used to feed to finishing pigs that need muscle shape until the final show. If you want more condition and body, blend with Primo 14 Chub.
