The Marwari horse undergoes significant physical transformation during its juvenile and adolescent period, roughly spanning from weaning at around four to six months through the age of three or four years. During this time, the young horse experiences multiple growth spurts that can make it appear awkward and unbalanced at various stages. It is common for a Marwari youngster to appear higher at the hip than at the withers for stretches of time as the skeleton grows unevenly, a phenomenon sometimes called being "bum high" that resolves as the horse matures.
The breed's signature inward-curving ears reach their final shape during the juvenile period, and the overall refinement of the head becomes more apparent. The Marwari's naturally arched neck and well-set head carriage begin to emerge as muscle development catches up with skeletal growth. Owners should expect the young horse's proportions to shift repeatedly before settling into its adult frame, and should resist the temptation to judge the horse's final conformation too early.
Bone and joint health during this rapid growth phase is critically important. The growth plates in a young horse's legs close at different times, with some not fully fusing until the horse is well into its third or fourth year. Overworking a juvenile Marwari before these growth plates have closed can lead to lasting damage. Regular veterinary assessments help track growth plate closure and guide decisions about when the horse is physically ready for increased workloads.
Weight monitoring during the juvenile stage helps ensure the young Marwari is growing at a healthy rate. Both excessive weight gain and underweight conditions can create long-term health complications. A body condition score should be assessed regularly, and feeding programs adjusted accordingly. The Marwari's desert heritage means the breed is generally an efficient metabolizer, and overfeeding concentrates can be just as problematic as underfeeding.
