TGC,
Yes those bulls are still at King Ranch. They are developing a new line of gerts, it does take a bit of time to achieve 5/8 Brahman and 3/8 shorthorn. I can not remember all of the details exactly. We have been fortunate to sell to King Ranch and a couple other Santa herds to accomplish this.
I should respond in more depth to our Rodeo Drive discussion. It is my belief that that that bull has genetic value in some places. Of Waukaru's 2011 calf crop only 1/2 of 1 % were sired by Rodeo Drive. I used the bull for several reasons. The daughters, granddaughters, and great-granddaughters have been major contributors to the genetics that our customers have demanded. The carcass merit of the cattle is top notch and the performance is real. Second, I often use bulls with extremely high EPD accuracies to compare to sires of low accuracies. This gives us, Waukaru, a better understanding as exactly how the current calf crop performs in terms of birth weight, calving ease, weaning weight, post wean wda, yearling weight, scrotal circumference, backfat, REA and IMF. We also collect cow body condition scores, preg rates, and DNA analysis of the cattle to determine their worth. Sometimes we remember only the good in a past herdsire, sometimes only the bad. It is interesting to note that when Rodeo Drive was used at his peak, many shorthorn cattle had a lot of dual influence. I have often wondered how the bull may have been perceived if he came along in 1977 or 1997. Other bulls that we have used in the past with a similar purpose of Rodeo have been Sutherland Ransom 179x, Mill Brook Ransom G9, Mill Brook Marc IV, Waukaru Chaps. Waukaru Prime Minister, W Austin City Limits. and even Stars and Stripes 6th.
Here is what I know so far of the only Rodeo Drive sired calf in the 2011 crop. He was born unassisted and weighed 94 pounds. The dam is sired Gold Card 5042 and I think she could hold birth weight down. (I would have thought the calf could have weighed even more) The bull ranked 12 out of 15 in his contemporary group for birth weight. I am anxious to see how the rest of his group compares to him in terms of growth. Time will tell. I think the breed has made great progress, I just want to check our work from time to time. On a side note, the dam of the Rodeo bull calf measured a 5.78 frame as a yearling, posted a yearling ratio of 108 and was the highest IMF female in here group of 2007 females. She has calved every spring and I have sold two flushes from her.
We know that in beef production we have made progress in herd health, nutrition, pasture management and many other facets. I think it is okay to stop and see if your performance level is because of genetic progress, or progress in animal husbandry. That is one of the reasons why I think it is beneficial to use older, proven sires from time to time.
