Charecteristcs Of Murrah Buffallo/Advice

[vrindavanfarms]

Hello,
I am a commercial Buffallo Dairy farmer.I am a bit confused about the lactating period in them.Somehwere I read that the cycle is like this:
Milking period: 10 months from Delivery.
Servicing: Within 3 months from Delivery.
Dry Period: 3.5 months.
But in my case the buffallo which calved in August dried in Feb.in just 7 months.Why is this?Is it because it was pregnant and that could be the reason for drying off early?If not mated in couple of months from calving then the dry period is prolonging.So what is the best way out?Also I observed that most of them dont show sign of heat and was just traced by taking male around.And also after mating,I was under the impression that they are pregnant but after 3 months when we checked for confirming,found some of them not pregnant and also during these 3 months neither they show any sign of heat nor the male sensed heat in them while he was taken around every day in mornings.Please advice,if anyone can guide me because these things leads to the erosion of profit by feeding them in prolonged dry period.
Thank s a lot in anticipation
