Need to be schooled on understanding a list of linebreeding - Page 3

Gustav:
     What is meant by "back massing"

Google it, ha ha!

bump..what is.back massing ?

Daryl: Somehow I suspect Gustav was not referring to a google search result.

Sorry, it's a made up word, and only part of Gustav's vocabulary.  I think it refers to a high coefficient of inbreeding (COI) due to popular producers appearing numerous times in 4th & 5th generations or further.  I wouldn't say I exactly agree with his concerns from an overall perspective, but there are instances where a particular individual dog might be preferably avoidable in that context (i.e., Klara zPS in Czech breeding).

I made the word and concept up.  

OK, care to explain...or must I rely on the google search result.

Gustav - I dont think you did that.

Guddu / Daryl, there's an interesting paper here:  but sorry I can't fix it as hyperlink

Google  BACKMASSING
then select  "Genetic Fidelity" by Keith T Weber.

Thanks hundmutter, tried downloading the software, did not have much luck. I think backmassing= COI (coefficient of inbreeding).

Hundmutter, maybe you're right, but Gustav was the only person I had ever seen use the term, probably at least three years ago.

English is a living language, and sometimes we subconsciously pick up ideas from origins we thought of our own making.  I suppose back massing is a more "informal" breeding-related term (i.e., like training terms such as "drives"), used by field practitioners, but probably not found in textbook reference material.

The "Genetic Fidelity" document by Keith T Weber was created April 15th, 2006.  Six and a half years ago.

Below is a four year old reference to the term from a database topic, "If you could have one GSD which would it be?"  The GSD example given is one that I'd agree with myself, when years ago EVERY dog I owned went back multiple times to the mentioned producer, particularly through Held v Ritterberg.

V Ex vom Riedstern Most dogs with any true power go back on him.Back massing on him is very good for work dog & breeding . The Only Way Forward Is Einsatzkommando

Yes, and Weber - who as you point out wrote the piece 6 yrs ago - is 'in'  
Pyrenean Mountain Dogs;  I don't know which country, possibly USA,
haven't tried to check.

The term 'backmassing' has been in use in England for 'many' years -
so many I can't remember when I first heard it, I've been around the
GSD breed for 40+ yrs.   I am 'guilty' of usinmg it rather a lot on here
lately myself, in ref to a couple of threds on Epilepsy and colour -
breeding.   ;p
