When zooming in on your horse you will see an overall view of your horse, a vague representation in words, bars and numbers. To care for your horse appropriately, you should have the diet choices all totaling around 100%:
• Alfalfa: This is a green straw, made from harvested alfalfa plants that provides a lot of basic nutrients. Alfalfa encourages energy, but shouldn't be given too much of, it can cause colic (a real bad stomache ache).
• Oathay: Oathay is a great base food that is mellow on the horses and provides some nutrients as well as keeps general weight on horse. It does not provide the horse a lot of carbohydrates (energy).
• Grain: Grain provides the horse a little treat, and supplemented vitamins that are not provided in oathay of alfalfa. It also has sugar which gives the horse a little jump start on energy. It can also cause colic if given too much of.
• Hot Oats: Hot Oats is basically what it says, with a lot of sugar. It gives the horse artificial energy but not the vitamins. It can make them very hyper, and can also cause colic if given too much of.

  Tip:The default starting food for a horse is sufficient, however I notice if I am constantly working on such a thing as discipline... the horse mellows out a lot so I usually give him/her about 10% hotoats and less oathay to keep it's energy up.

Horses in stables should be trained somehow everyday, it may lose it's stats or training. These horses are put in to stalls. Horses only loose their stats if it is above their natural level (100% is the natural level, you can view this percentage on the horses page adjacent to it's stats if you are the owner). Horses in stalls should be fed at 100%. Usually if fed at 100% and given attention to daily, horses condition remains near 100% and their energy recoups fully. They are also kept clean and ready for show!
Horses in pasture do not loose stats, but their energy is not optimum nor is their condition. They do loose training slightly over virtual days/turns. It is cheaper to put horses in pasture and if you have a lot of horses, it provides a great way to sort out your horses and cut your expenses. Sometimes you may want to keep a horse in pasture until it ages, or mayhaps you just use that horse as a broodmare or something. Horses in pastures, due to their condition not at par nor their energy, will not have the same performance as one in a stable.

Tip:Keep horses you are training and showing in the stable, and horses that you are not training or showing in the pasture.

The condition bar on your horse's summary or its individual page represents its overall health. There are a few factors that effect this: Its treatment, health problems, age and location. New horses (new borns that are born a year old ;] ) are not born to 100%, and horses in pasture do not reach 100%. Condition rises over time (virtual days) if the horse is fed and given attention. If the horse has a health problem such as exhaustion, condition can be improved a bit more each day by treating it in the train horse option. Once a horse regains condition, and energy and the treatments are given the health problem will likely go away. Each health problem has it's own effect on a horse, some may decrease speed, energy regain, or performance etc... The health issues are not yet fully implemented as of writing this, and they will be added over time.

Tip:To improve health: Make sure diet is at 100% (good diet if colic: 40 oathay 15 grain 30 alfalfa 15 hot oats just not too much 'hot/sweet food!'). You may proceed with a light training every day as long as energy is OK, to speed it up slightly, you can Treat Injury (training option for broken in horses).

The horse's Score is allotted to individual horses when they compete. The quantity given is based on: how many horses were in the event, how the horse placed vs. the other horses, and how open the event was, such as level. It is a good way to judge how a horse may perform, horses with higher score have had more experience in competing, and that slight extra edge. It is also important to see how many events the horse has entered, to see if it really has the natural talent and the training. This can be done by viewing the W/P/S. W/P/S stands for: Wins/Places/Shows. Wins are the number of times the horse has won an event, Places are the number of times it has received second place, and shows are the number of times it has recieved third place. Usually around the W/P/S it will mention out of how many events that horse has competed in, it has recieved these placings.
Net Earnings are how much the horse has actually won in events minus the entry fee for its owners. It does not include bets won on the horse.

Mood represents the horses current mood. A horse that is given a lot of sugar in it's diet over time...will probably be more hyper. Diet and training types effect a horses mood. Generally, a sprint around the track will make it a bit more spirited than a discipline lesson in the arena. Mood can effect it's performance when competing some: for example, a lazy horse on the race track might just not run as fast as it could... where as a hyper horse in the dressage arena might think the letter 'B' was out to eat him or her.
Personality is the horse's natural state of being. It is usually determined on genetics and it's breed. A few factors such as neglect can change it. A very docile horse will probably not become as hyper as easy as a horse that is naturally high strung. You can also discipline horses to make them more mellow, and enrage to increase their attitude (however- if not a bronco horse, the horse may loose training skill- confusion!).

Natural Vs. Actual : Natural stat is your horses natural potential: It is represented by the vague descriptions Poor, Average, Good, Very Good, Supurb . This is decided on its parents, and Breed. It also decides a good portion of its foals outcome.
Actual stat is the percent of the Natural stat that horses have achieved, It is represented by a percentage (%). All horses are born with 90% of their natural potential. Actual stats are improved through excericizes (its training) and are what events mostly judge on! It has a slight effect on outcome of foals. Examples: A horse with 140% Good Strength probably actually stronger than one with 90% of supurb. A horse with 90%Good Speed is indeed slower than a horse with 90% Very good Speed.

Stats are unique to each horse. Some horses are born naturally stronger than others, where other horses can be very stupid. The stats pretty much determine what your horse will be good in. When you view your horse, you will see the four stats, and a percentage above a vague description of it's potential. There are two different types of factors for each individual stat which is listed below. The two are: natural and actual, or genetic and training. Let's use Strength for example The percantage is the percent of natural strength the horse has achieved. A horse with 120% strength will not necessarily be stronger than one with 90%. You will notice a weeker horse may reach it's potential strength faster or the same than one that is strong. This is only because it is a smaller number to reach, however this horse will not gain strength overall as fast as one that is naturally stronger. Also, the higher the horse's individual stat is, the slower it gains, so training a horse with poor speed to become the fastest horse in the world just might not happen in its lifetime, not only does the speed get harder to gain because it is high, but it gains so incredibly slower because of it's natural speed, not only that, but it's fighting its old age which slows it down!
Factors that determine the natural stat are its genetics (mom and dad) and breed. There is a way to increase this or decrease it per an individual horse but it takes a lot of work! Think of it as this way... a horses muscles can be short and thick (strong), or long and lean (endurance). or long and strong (speed). It is up to you to balance to decide what condition your horse needs for maximum potential. This can happen technically when a horse reaches its stat cap, which means a lot of training and age. A horse that has been trained very excessively in say strength, will have its natural strength increased very slowly, however, other stats will drop.
To summarize Natural vs. Actual (str., end, speed or int): Natural abilities of stats are incured mostly by inheritance and breed, as to the Actual is the actual ability which is gained by its training at a rate based on its natural ability. All horses are born with 90% of their actual stats, and given a vague discription (poor, good, very good etc...) of their natural abilities. It is kept as a vague description for reasons of surprise. In reality- one does not really know if a champion is born but one can make estimates as to its potential. Almost Any horse can Be a Champion if it is TRAINED And trained as in Every Turn - a Few times a turn - and train in everything!.
• Endurance: Endurance is your horses stamina. It measures how fast a horse recoups energy, how far it can go at how fast, and how much work it can do. It is important to more extents than others in all training specializations. Endurance is increased by excercizing it in any way, some ways more than others, such as a five mile ride will increase it's stamina more than a dressage session.
  
• intelligence: intelligence is how well your horse can accept knowledge and be trained. A smart horse will learn disciplines and understand concepts faster than a stupid one. It is important mostly in Dressage and Eventing, and some in jumping. intelligence is increased by specific trainings such as dressage or disciplines, whereas a sprint around the track might confuse the horse some in some disciplined trainings.
  
• Speed: Speed is basically how fast a horse can run. Obviously it is most important in racing, and somewhat important (when it comes down to the final end I suppose) in endurance. It can also be critical in an event such as show jumping or eventing, but strength usually determines this type of speed - how fast a horse can get over a jump course! Speed can be increased by working on the speed muscles- by going full speed, and by a heavy work out of an endurance ride.
  
• Strength: Strength can measure how well a horse can carry its rider, or do specific tasks such as jumping. It is important to more extents than others in all training specializations. Strength can be increased in most types of trainings, jumping being more than others.
  

  Tip: A horse that has achieved more than it's natural skill/stat (100%+) will slightly decay if left with out attention for a day in it's stall (stable).
