The process of bringing a mare into heat, or cycling, involves using hormones like hCG (human chorionic gonadotropin) or prostaglandins. These hormones work by mimicking the natural hormonal processes that occur during the estrous cycle.
Sweating in horses is primarily associated with:
* Physical exertion: Horses sweat when they work hard, run, or are hot.
* Stress or excitement: Horses can sweat if they are anxious, scared, or stressed.
* Illness or pain: Horses can sweat as a sign of illness or pain.
While the hormones used to induce estrus can cause some temporary changes in a mare's behavior, they do not directly cause sweating.
If your horse sweats after receiving a shot, it is likely due to one of the other reasons listed above, such as stress from the injection itself.
It's always important to consult a veterinarian for advice on inducing estrus in your horse. They can advise on the appropriate hormone, dosage, and timing, and can help to address any concerns you have about your horse's health and well-being.
