There's no set pattern like deer. They shed around their birthdays. From what I'm seeing their horns grow back in about 5 to 6 months. I don't know that for a fact but I've been wathcing one grow since about November and I'd say he'll be hard horned by end of Feb. to early March.
I believe it all depends when they are born, some shed in the fall and some in late spring. I think the growth season is about like any other deer 5 or so months.
Their yearly cycle is like a WT in the number of mos. to grow, # of mos. hard horned etc. Unlike a WT, their cycles are not seasonal or triggered by the amount of daylight. Axis cycles revolve around their birthday, and since does can breed anytime of year you can have animals in all stages at the same time. However, there seems to be a large % of animals that follow a core cycle and go hard horned around the end of May. You can do the math on the rest.
We've found about a 70/30 split between those that are hard horned May-Oct/Nov versus those that are 'off cycle'. As mentioned, they start their cycle based on birth date, it's just that most are born to coincide with that cycle.
In india, their major cycle is based primarily off the rainy seasons, with the improved range conditions triggering the female to go into eostrus a couple months after the rains begin. Would make sense if they are following a somewhat similar pattern here as late spring is typically our wettest time of the year, with a lesser wet period in the early fall.
