Do not stress or overheat breeding animals.

10.8.5 Do not stress or overheat breeding animals.

Stress and overheating should be avoided in both female and male breeding animals because it may make them infertile. If the female must be taken to the male, she should be taken before she comes into heat. If she is already in heat, she should be walked gently and during the cool time of the day. In boars, overheating may cause infertility for two months.
