Producing a top percentage Simmental is a lengthy process, but it can be done. This Planned Mating will produce a PBSM calf due October 2013. We have to ask ourselves and our customer base — What kind of bull or heifer do they want? In this instance, the parameters that we were trying to improve upon are carcass merits, while not greatly affecting any of her other traits we deem as being better than average for the breed. Look at this heifer for example: EDR Black Berry Y 04 CE > 15.5 Top 10% BW > -2.1 WW > 60.5 YW > 95.6 MCE > 13.4 MM > 27.4 MWW > 57.7 Doc > 12.8 CW > 23.9 YG > -0.21 Marb > 0.61 BF > -0.030 REA > 0.73 SF > -0.34 API > 161.0 TI > 83.4 The numbers below the EPD’s are Accuracy (ACC), which is always low for a young animal like EDR Black Berry because she hasn’t had any progeny, yet (calves). The numbers below Accuracy represents how she ranks in each category, nationally. A trait 20% or above represents a trait leader. Below are her rankings in all categories beginning with CE 10% etc. I will highlight her traits 20% or above in bold. % 10 10 45 40 3 15 20 20 55 45 5 60 15 35 2 2 This is important so we know where she needs improvement– the question is how can we now improve future generations, since we know her strong points and her weak points. This is where we use Planned Matings so we can mock breed her to various bulls to see which bull will fit her the best. So pull up the Planned Mating page and on the Dam “Box” enter her number, which is 2606986 and for the Sire “Box” enter 2605948. https://herdbook.simmental.org/simmapp/template/plannedMating%2CPlanMate.vm Push calculate and the resulting matched mating will be her future calf with estimated EPD’s. Now we can see where we improved. Again, my goal for this breeding was to increase her carcass merits, which include BF, YG, REA, SF, without greatly affecting her other good points. CE > 18.7 Top 1 % BW > -2.4 Top 10 % WW > 58.2 Top 55 % YW > 93.6 Top 45 % MCE > 15.4 Top 1 % MM > 28.1 Top 10 % MWW > 57.2 Top 20 % Doc > N/A CW > 21.9 Top 60 % YG > -0.36 Top 20 % Marb > 0.48 Top 15 % BF > -0.06 Top 20 % REA > 0.88 Top 3 % SF > -0.40 Top 15 % API > 166.0 Top 1 % TI > 80 Top 1 % I say we did — YG, Marb, BF, SF, are all above 20 % — which are Trait Leaders nationally. In Fact, out of all 16 measures (EPD’s) –this calf is a Trait Leader in 12 of them.
