As a Simmental and Simangus breeder I can say that probably there are only a few good bloodlines available and once you have gone thru them its pretty much over. It would take a lot of time to go back to Fleckvieh and start a new PBSM bloodline --I think that is kinda where we are. There are only 2 Red bloodlines available in PBSM now that any serious cattleman would want.
I'd say that 80% of the bulls available today in Simmental have Legacy in their background --very much overused --some are inbred Legacy. For example a popular animal is Upgrade --not only does he have 600U in his bloodline 4 times he also has Legacy, so once you use him you have grossly inbred everything you own. He's okay for the commercial sector as a Terminal sire, but for the PB business he is a bust. He is mostly popular in the Show Sector within Simmental.
The chickens are coming home to roost on these show cattle bred bulls -- people are finding out that they are a crap sammich on their numbers and dont perform well in a commercially focused operation.
There are two sectors within Simmental: the Performance Sector and the Show Sector.
My analogy, though harsh, is just to better differentiate between the two for better understanding.
The Performance Sector are the breeders that take all the data. We are the members of the Total Herd Enrollment Program, Carcass Merit Program; we send our bulls to test stations; we collect the data on CE, BW, WW, YW, MCE, MWW, MM, DOC, YG, Marb, BF, Shr, API, TI, Scrotal, Hip Heights, Ultrasound, frame scores, etc. and this is where the EPD's and Indices are derived from.
The Show Sector are the breeders that put in little or usually no data in the system. They are not members of Total Herd Enrollment, they don't support the Carcass Merit Program; they don't put bulls in state Bull test stations and they are usually the first ones to tell you that EPD's are not worth anything. Even though they do not collect any data they use the data.
My analogy for this is the Tax Payer and the Welfare Recipient.
The Tax Payer, being the members of the Performance Sector; add to the till in the form of data collection. We are the ones that provide all the information for the EPD's and Indices. We have been propping up the Show Sector for decades as they utilize and benefit from the data we collect. It's just like the tax payer paying the way for the welfare recipient.
The Performance Sector is more commercially focused as we think that any breed association that is not commercially focused would be a dying breed. We are the Tax Payers providing for the welfare recips.
The Welfare Recipient, being the members of the Show Sector; add nothing to the till, yet benefit from those who do all the work. They are the first ones to tell you that you should base your quality assessments on Phenotype. They are the ones who have been able to stay in business by keeping the misinformed and/or ill-informed buyer in the dark on EPD's and Indices. These are the people raising show cattle that have no supporting data of any quality parameters, because they do not input any data – their data is derived from the Performance Sector.
The show sector folks are really upset over the EPD's, Indices, DNA testing --basically anything that brings forth more transparency -- mostly because their cattle wont work for the "guys" trying to make a living
"Here" Salers had a reputation for nasty personality.
