Great feed

Bought it for my 19-month-old filly. She was on Tribute Growth since she was weaned, but for the past few months she looked very gangly and ribby. Since I feed Purina

Bought it for my 19-month-old filly. She was on Tribute Growth since she was weaned, but for the past few months she looked very gangly and ribby. Since I feed Purina Pro Plan to my cats and Purina Veterinary diets to my dogs, I figured I'd give it a go. Marzipan looks great and is starting to muscle up! The Outlast supplement is also great for optimizing feed uptake. I'm in the process of switching my senior gal (21) over to the senior ultium. The low feed rate saves your money and cuts back on the amount of dry matter and starch you have to feed. Also, it's lower in sugar and starch than most growth feeds, so I'm not as worried about insulin changes!
