1 The use of the electron microscope has advanced our understanding of cell biology further ... In the early 1930's this limit had been reached and there was a scientific desire to see the fine details of the interior structures of organic cells (nucleus, mitochondria, inside the nucleus itself, nucleolus).
MaxQ Tall Fescue Grass - Safe For Horse Pastures & Hay. Fescue toxicity has long been an issue for horses, sheep and cattle. Endophyte-free varieties of Tall Fescue Grass were developed, but they suffered from reduced plant hardiness and survival.
The equine digestive system is designed to extract nutrients from grass. Horses need long-stem fiber to remain healthy - in a perfect situation horses will graze for approximately 18 hours per day.

Hay is made from grass, legumes or cereal crops that have been mowed, cured and baled. The type of vegetation from which hay has been made can vary based on location, availability and preference of the horse owner.
