Creating Jac: selecting bloodlines for performance reining horses

2013 NRHA sires Quarter Horse NewsMy husband is one of those guys, you know, the ones who know all the stats from their favorite football team including the past, present and up-and-coming. He doesn’t only do this for his sports team though…he does it with reining horses too.

His knowledge of reining horses-past, present and up-and-coming is quite amazing. He loves analyzing bloodlines and performance records. I give him credit for creating Roxy, Vaquero, Jac and many other great horses because he chose the combination of sire and dam resulting in those horses being foaled.

Today Jesse showed me some interesting statistics from the April 2014 Quarter Horse News. The first thing he showed me was the chart in the photo. These are the top sires in the NRHA in 2013 based on how much their offspring won in 2013.

Jac (Jac’s Electric Whiz) is by Jacs Electric Spark who is number 4 on the list. What Jesse was pointing out though was how high Jacs Electric Spark average was. For example the first sire, Wimpys Little Step, had 359 foals show last year.  They earned $1,429,148 bringing their average to $3,981.00.

Jac’s Electric Spark averaged $6,273.00.

On another page of the News were statistics on Maternal Grandsires, which is the sire of the mother. Jac’s mother was Whizards Baby Doll who was by Whizard Jac.

Whizard Jac was ranked number 16 on this list BUT his average was higher than any of the 15 horses above him on the list.

Keep in mind that Jesse chose to create Jac four years ago. Not bad Jess, not bad at all.

    Finding this late, but loving it. The Jac series were the reason I bit the bullet and bought my first untouched 2 yr old (also a sorrel stud colt !) and decided to start him myself in 2016. Soon 4 yrs later he’s still with me, still struggling to become a reiner, lol, and I just got myself a new reining project, this time a weanling ouf og a Gunner son. Thanks for the Jac series, it will always remain one of the best horse resource in my view.

    I think some (just some) stats can be a bit misleading, when you factor in that in a lot of cases, anyone who can afford the stud fee can breed to a particular stallion. Of course, having said that, it makes a point that all stallions available to the public can be bred to junk (my word, but you get the picture) mares, and the stallions that come out in the top stats must be contributing a Lot to these mares. However, in the reverse, it does make me wonder if the stallions that rank very highly on the Lists, have owners who have been more selective regarding which mares they accepted to breed to their stallions. Just a thought.
    When I was in the breeding game, I DID reject mares, based on my personal opinion of the mares quality and temperament. I was fortunate enough to be in a position where I could afford to do that, and undoubtedly this would have made a difference in how many decent foals were produced. Of course, if these foals are not competition horses, it is again speculative as to their quality.
    Having said all this, I DO believe that breeding horses that have competed successfully, and held up to the rigors of that schedule, would always be your best bet!
    Thank-you for all your insights and excellent articles. What you did with Roxy (among others) proved beyond a shadow of a doubt that you know what you are talking about.

    I wanted to se Jac’s bloodlines so I looked him up and the QH news says hes dead…. I know from your posts that hes not but you might want to straighten that out lol

      Did you accidentally look up his sire- Jacs Electric Spark? He died. I will try to look into it.

    It is truly impressive to me how, he is able to keep all this knowledge straight !! Never ceases to amaze me. He has done a great job creating these horses. When we are ready to breed Izzy…. iwe will be seeking his knowledge once again !!!
