It depends on the horse's age, use and reproductive status. Protein requirements can range from 8% to 14%
One gram of protein per kilo of bodyweight is about right for most people (those who aren't bodybuilders etc...)
Protein requirements do increase slightly with training and exercise but this is insignificant in comparison to the protein needs of a young, growing horse, or a lactating broodmare.
Some of the best food protein sources are meats, eggs, dairy, beans and nuts/seeds. You should be ale to meet your daily protein requirements without turning to supplements.
if you don not check your horse daily then your horse will die.

350-400 grams of protein daily
The Federal government's Recommended Daily Allowance (RDA) for protein is 0.8 gram per kilogram (2.2 pounds) of body weight. For example, if you weigh 150 pounds, the daily RDA for protein would be about 67 grams of protein. However, your daily protein requirements vary considerably according to factors such as lifestyle, physical condition, overall health, age, gender, carbohydrate intake, training level, and the type, duration and intensity of physical exercise.

The actual cure is simply to get your daily intake of multi-vitamins, and to get a high percent of protein daily specifically from eggs, whey protein, and casein protein. Also you must exercise daily.

No there is nothing that a pregnant horse shouldn't eat that she wouldn't eat otherwise. During pregnancy it's wise to increase her protein with a higher percentage grain/sweet feed. Also good to up her hay to a 21% protein such as alfalfa or an alfalfa mix.
15-50 grams per day limits the body's need to break down protein and will allow protein requirements to be set lower than a diet providing essentially zero carbohydrates per day.
