There are several research papers on chital.
The best I've seen by far on AI,breeding & management is by Dr A English from Sydney Uni & published about 1991.
Chital deer don't have a pronounced rut or season like whitetail or european deer.Hinds are receptive a few weeks after calving & four calves in three years is common.Chital suffer capture myopathy more than any animal I've worked with & must be conditioned or trained slowly when introducing them to yards or handling.This complicates AI.
I cull anything that is not "typical".In the words of Dr English "don't mess with them".
I look for strong brows & inners with a wineglass shape,but not too wide.
Narrow heads are culled & I cull all the double fours that show up ,also poor brows & inners & non symetrical heads.Chital are a double three deer & look good enough without mutations or domesticated morphs.
One of those malformed deer can be found in my slow cooker right now.lol
