Equine exertional rhabdomyolysis (ER) is a syndrome that affects the skeletal muscles within a horse. This syndrome causes the muscle to break down which is generally associated with exercise and diet regime.
First symptoms are usually muscular weakness, soreness and stiffness causing problems with walking and breathing. Within hours of first symptoms horse may be unable to stand and in 72 hours of the onset of signs mortalities may occur. [16] [13] [1] The mortality rate of atypical myopathy is high; only 30-40% of affected horses survive. [9]
Four chambers (pollen sacs) lined with nutritive tapetal cells are visible by the time the microspores are produced. After meiosis, the haploid microspores undergo several changes: The microspore divides by mitosis producing two cells. The first of the cells (the generative cell) is small and is formed inside the second larger cell (the tube cell).
Heart rate is often used as a measure of the animal's pain level and a heart rate >60 bpm is more likely to require surgery. [25] However, this measure can be deceiving in the early stages of a severe colic, when the horse may still retain a relatively low rate. [28]
Microgametogenesis is the process in plant reproduction where a microgametophyte develops in a pollen grain to the three-celled stage of its development. In flowering plants it occurs with a microspore mother cell inside the anther of the plant.

Grass is a natural source of nutrition for a horse. Equine nutrition is the feeding of horses, ponies, mules, donkeys, and other equines. Correct and balanced nutrition is a critical component of proper horse care. Horses are non-ruminant herbivores of a type known as a "hindgut fermenter." Horses have only one stomach, as do humans.
