What’s the Weight of a Foal?

During the growth and development process of horses, they get to undergo various weight stages. Firstly, the first weight record made in a horse’s life is during birth when the horse is still a foal. When foals are born they are usually around 10% of their parent’s weight. For example, a newly born thoroughbred horse from a 1000lbs mother will probably weigh 100lbs. The time of birth is a very key factor when it comes to the size and weight of a foal. The gestation period for horses is usually 340 days. Any baby horses born earlier before the gestation period is mature will obviously weigh less even though their weight increases with time. 

How to Weigh Horses

Horse owners and stablemen usually use livestock scales to determine the weight of a horse. Hereby, the horses are supposed to walk on the livestock scale which estimates the approximate weight of the stallion. A horse owner can buy a livestock weighing machine from the local store at a price of €650 or even more dependent on the brand and its efficiency. 

However, many people find horse weighing machines to be very expensive thus seeking alternative approaches that can help you estimate the approximate weight of your racing stallion. Others decide to go for public weighbridges whereby they put the horse on a trailer, measure the total weight (horse+trailer) first; then measure the trailer without the horse. Subtracting the weight of the trailer from the total weight will give you the approximate weight of your horse. 

Using horse weighing machines

The sales of weighing machines have rapidly risen recently since they have become popular in the thoroughbred industry. Stud farms use weighing machines to weigh newborn foals as soon as they are born and racing stallions as well. Vets also use these machines to keep track of their patients’/sick horses’ weight. Trainers have proven to use this equipment the most since they have to track the subject’s weight from the start of training until when it’s over and the race competition draws closer. Therefore, weighing machines are likely to produce the perfect answer for the frequently asked question by horse enthusiasts, ‘How much does a race horse weigh?’ Let’s have a look at the various breeds suitable for horse racing and their specific weight class as well.
