Any clean jpj sons been tested?
justintime said:The TH defect is identical to the defect that was in the Galloway breed back in the 50s and early 60s. The Galloway breed eradicated all lines that carried the defect, and some very good cattle had to be eliminated in order to do this. This was a tough decision but it results in the breed eventually being free of TH.
When Dr Beever was researching TH in the Shorthorn breed, he commented to me that he found it rather unique that the TH defect in Shorthorns was identical to the defect in Shorthorns. He said while the same mutation could happen in two different breeds but it would be a really rare occurrence for this to happen.
I related a comment I was told by some Irish Shorthorn breeders, when I asked where the Quanes ( Deerpark) had found the sire of Deerpark Improver? They said that after many generations of just using bulls of their own breeding in their herd, the decided to add some outcross breeding, and had purchased a red bull from the local auction market. At this point, Dr Beever interrupted me, and said that " this is finally starting to make some sense" He said he was almost certain that this auction market bull probably went back to some old Galloway breeding in his genetic make-up. This certainly would be the easiest way to have the same genetic defect appear in two breeds. ( it may also answer the question of where all the hair comes from in most TH carrier animals)

Knabe- Yes Galloways still carry the same double haircoat they have for centuries. Galloways tend to be bigger boned also.
-XBAR- said:Defects have varying levels of expression. Many calves afflicted with DS appear perfectly normal.
I dont remember all the details on the two bulls I had just the fact that they were different than the typical improver TH.I know there was a mutation called Outcast that was out there.nativeman said:I thought the improver line was the only line of shorthorns with TH. What were the other ones if you could say.Is that why you don't see much of all the English imports from 30,40,50,60s in breeding lines any more.
OH Breeder said:-XBAR- said:Defects have varying levels of expression. Many calves afflicted with DS appear perfectly normal.
Being afflicted would mean to me displaying the defect. Some cattle can be DS Carriers but are not visibly affected. DSC can have normal calves. From what I was told then it becomes a similar matrix to TH when mating two DSC and or a PHC to DSC.
I haven't quiet wrapped my head around DSH yet.
beebe said:Am I safe from defects or do I need to test the natives to make sure there are no defects?

all cattle probably have defects. no one is safe. no one needs to hyperventilate, bad mouth people about who hid what etc. technology and communication now makes it easier to identify and breed around them instead of just taking cull price. everyone has probably sold a carrier of something to someone. it's time to move past the past and move on.
OH Breeder said:I would test to make sure you are free.
This has been bothering since I read it the first time. If the Galloway breed got rid of defects why has the Shorthorn breed not done the same? I would think that it would be a great advantage to be able to say that the breed is clean.justintime said:The TH defect is identical to the defect that was in the Galloway breed back in the 50s and early 60s.
