PLANNING FOR NEXT SEASON In late summer, the large majority of breeding is completed for the year and if things have gone as planned, the mares have settled. This is a good time to begin planning for the next season in order to avoid the full schedule of a breeding season in progress. Early attention to the animals’ individual health can cause next year’s breeding season to be successful with less cost and frustration when spring comes again. A mare’s normal, biological breeding season starts in mid-April and often extends through October. But most breeding activity is completed in July, making late summer a good time for examination. Record keeping, conception rates and, more specifically, horses that are not exhibiting peak reproductive performance – both mares and stallions – should be examined.
