GELDING
After being castrated a male or colt horse is said to have been gelded. There are a variety of reasons behind this seemingly rather harsh practice.

After gelding, horses are generally regarded as being easier to train and concentrate more readily on their racing.
Even more practical for National Hunt, gelding can prevent the extreme discomfort experienced by entire horses when jumping over hard fences, historically made from birch.
Irish horses intended for chasing are gelded automatically at an early age.
Most chasers are in fact geldings.
For a long time, many big flat races were not open to geldings, but this has now changed with most of the classics now being opened up to them.
One obvious financial argument against gelding is that after winning a major, a colt is instantly worth millions to big stables or stud syndicates.
