When it comes to how much a horse ejaculates there is no definitive answer. Depending on the horse’s size age and health the amount of seminal fluid a horse produces can range from 4 to 20 litres (1 to 5 gallons). The record for the most ejaculate production in a single stallion was 18 litres (4.
75 gallons).While the volume of ejaculate may vary the averagehorse produces approximately 700 million sperm cells per ejaculate. The number of sperm cells per ejaculate is relatively constant regardless of the stallion’s age or health.
One stallion can ejaculate enough sperm in one breeding season to father over 1000 foals. However each mare will only produce a limited number of offspring in her lifetime. The average mare will produces between 10 and 20 foals in her lifetime though some mares may produce as many as 30 or more.
When a stallion ejaculates the semen is expelled through the penis at a rate of about 16 km/hour (10 miles/hour). The average ejaculation lasts for about 15 seconds but can range from 10 to 30 seconds.The majority of the seminal fluid is composed of water but it also contains sugars proteins minerals and vitamins.
The seminal fluid serves to protect and nourish the sperm cells as they travel through the mare’s reproductive tract.The average horse ejaculate contains between 200 and 300 million sperm cells. However only a small percentage of these sperm cells (usually between 10 and 30%) are actually capable of fertilizing the mare’s egg.
The fertilization success rate can be affected by a number of factors including the stallion’s age health and the number of sperm cells present in the ejaculate. In general younger stallions tend to have a higher fertilization success rate than older stallions.Healthy stallions also tend to have a higher fertilization success rate than those that are unhealthy.
Stallions that are suffering from a sexually transmitted infection or other health problem may have a lower fertilization success rate.Finally the number of sperm cells present in the ejaculate can also affect the fertilization success rate. In general the higher the number of sperm cells the higher the fertilization success rate.
So how much does a horse ejaculate? It depends on the horse but the average stallion produces between 4 and 20 litres (1 to 5 gallons) of seminal fluid per ejaculate. This fluid contains between 200 and 300 million sperm cells.
However only a small percentage of these sperm cells are actually capable of fertilizing the mare’s egg…
