I've seen magazine advertisements for "Green Feed" the "environmentally friendly equine feed recently made available in the United States.
Every bit of Green Feed, from the packaging to its formulation, is designed to be more environmentally friendly. Green feed includes a variety of proven, natural technologies to ensure digestive health, boost immune function, and provide optimal mineral balances. Packaged in a bag made from recyclable materials and printed with soy-based ink, this new product was designed to leave a small carbon footprint and minimize energy waste of transportation" (thehorse.com)
The strange thing is, the website for the company that makes Green Feed is relatively vague about the product, and I can't find a single picture (outside the manufacturer's brief glimpse in a slide show on their home page) or place that sells Green Feed online. Can someone clarify the mystery?
