[QUOTE="JustSimmental, post: 869084, member: 14624"] The reason I am asking these questions is that I am looking for a Blk Angus AI sire to use on PB Simmental that does not pose a threat to my bloodlines, as I don't want a potential buyer to look into a calves background and see a trait trac of yellow or red-- it just doesn't look good. Simmental has trait trac -- which shows any known genetic defects from all Sires regardless of breed. 1. Why do PB Black Angus breeders continue to use the GAR Precision line when that line has been proven to be a tested carrier of NH and AM and a population risk for CA genetic defects? 2. As a PB Angus breeder what is your threshold you use in choosing an AI Sire by EPD's. For example, what WW EPD would you consider too low. Another example-- REA. REA is not a Blk Angus strong suit and when crossing them with Simmental we end up with an animal that is borderline substandard for Sim/Angus in this category. 3. When you are choosing a Blk Angus AI Sire --what EPD's are you choosing for the most and why; what EPD's are your buyers looking at the most? (growth EPD's or carcass merit). 4. An example of what kind of cattle I want to breed for: i will just pull a cow off my list of PB Simmental cows > This is a GW Lucky Dice cow CE BW WW YW MCE MM MWW YG CW BF MARB REA SHR API TI 8.3 0.5 34 71 5.6 5.4 22.1 -0.01 5.3 .05 0.50 0.31 - 50 121 70 When I look at this cow I want to improve BW WW YW REA API TI and I am trying to decide what Angus Bull might help improve her numbers. The problem with Blk Angus is their BF and REA is bad; their MM is sometimes bad; WW is sometimes bad; and YG is bad. So I plan to use SS Fast Track When I run this PB Angus sire through ASA his number change a good bit to the following: BW WW YW MM MWW YG CW BF MARB REA API TI -5.7 47 100 4.9 28.4 .31 14.1 .11 1.14 .07 175 109 The progeny from this pairing ends up with these numbers: BW WW YW MM MWW YG CW BF MARB REA API TI -2.6 42 85 5.2 25.3 .15 8.5 .07 .83 .19 148 89 This individual ranks in the top 1% nationwide for API and TI but this is where I lose: YG BF and REA is terrible. I also end up with a Yellow trait trac in the lineage. Do you think the bull buyers care? Anyway I would appreciate some ideas and your honest thoughts. Thanks in advance JS [/QUOTE]
