    Default Gonadal reserves - depletion and replenishment - stallion dependant???

    Is each stallion completely different in this regard? Would their reserves deplete in different degrees and would they replenish in different degrees as well?

    Are there any studies done as to percentage depletion over the course of XX days if they are used once a day? Twice a day? Three times a day over the course of XX days or weeks as to the semen quality degeneration and if you stop breeding with them today and give them a break, what percentage - number wise - is replenished each day that they are idle?

    I am trying to explain to someone that the course of action they are taking with their stallion is not in the best interest of the semen quality of the stallion but have no idea of actual numbers / percentages to quote to him

    Can the gonadal reserves ever deplete to "0" ??? And if that happens, how long before they replenish or is that something that would take weeks to get back to full operating capacity?

    And they dont have a microscope so no point in asking them to take a sample over the course of XX days and look for themselves what is happening to the semen itself but that suggestion to get one - pronto - has been put forward to them

    Many thanks

    I have no idea about studies but I do know that there are some stallions in Kentucky that at the height of breeding season that are covering mares two, and sometimes three times in a day for a few months.

    ^ I wonder if in those cases they are keeping an eye on numbers through the post mount ejaculate and governing themselves accordingly. And if they allow the increased activity in April/May knowing full well in 60 days time the activity for that stallion will be lessened or over with for the season

    Would think it would be stallion dependent. Would also think that it must be extremely hard on the stallion's hocks and back - plus keeping weight on him might be an issue.

    TC - they breed when the mares need to be bred, and are full on busy starting the middle of February. Many of them are also duel hemosphere stallions so when they're done here they shuttle elsewhere. There are stallions in Kentucky that are breeding over 200 mares between Feb 14th and early June at the very latest.

    The busiest last year was Cape Blanco - bred 220 mares in Kentucky then shuttled to New Zealand. Giant's Causeway has kept up that sort of schedule for years.
