Hello All; I have a question about Extension and spotting. Does Extension cover up all white spotting? If so, can I assume that a black sheep with a white...
Hi Linda See info below from the mendelian site. Gail ... Locus name: Extension <> L<>ocus symbol: E Gene effect : The allele dominant black (ED) is a very...
Hi Gail: Thanks. I am interpreting "totally eumelanic" to mean no white anywhere on the sheep. So a white head spot or other small white spot would mean the...
That's the way I understood it to mean. Probably the only way to know for sure is to do test breedings. Sometimes it's worth it, and sometimes not. It would be...
I was under the impression that the extension locus only covered the Agouti locus. Therefore spotting would be able to occur. I have small head spots on ...
Hi Laurelen: Thanks for your input. Shetlands, the breed I am working with, have all sorts of head spots as well as the larger body spots. I don't want to ...
Jacobs are considered extension black, and have spots. My understanding was always that extension did not affect spotting at all. I have had numerous sheep out...
Hi Jennifer: Thanks. I guess I had better forget the notion of eliminating Extension if the sheep has solid and white. Any refinements, ideas or additional...
I am probably way out of line saying anything about this Extension question.....but I'm going to risk it because I think there could be an error in some of...
Hi Carol and others, Extension fascinates, confuses, and thus frightens me. I have a couple of questions ... 1. What was Extension introduced in the 1970s? ...
Extension black (dominant black) and spots do indeed go together - and frequently! This is the allele in Jacobs, Dorpers, Akaraman (I think) and also in...
Linda - this is such a timely topic for us. :-) We have 4 black Finn ewes with various HST (Head, Legs/Socks, Tail) white spots who were bred via AI to...
Hi Franna: I think you have the gist of it. As I understand your AI program, the Gotland semen would have been collected from a "grey" ram. It the ram looks ...
I've done a lot of research on color genetics for cows, goats, pigs, and sheep (we have them all). It's interesting how the people involved with each...
Bill and Linda - I will try to address both of your e-mails together. The only caveat being : I know Romney, I do not know Shetland or Jacob. However,...
Hi Maggie: I run an Agouti coloured flock of about 35 Shetland breeding ewes. The ED that concerns me (and Bill with his flock) has come into this year's crop...
Hey all, I had triplet lambs on the 16th of March. Last Friday, I sold one of them as a bottlebaby. Apparently he has refused to eat anything and has just ...
Do not bottle feed a lamb that is not sucking/swallowing or it will end up with aspiration pneumonia. Bottle feeding lambs is quite a chore and I only do it...
Thanks for the info Anita, We did just tube him tonite, got 2 oz (more or less) down him. He seemed to perk up a little, at least it didn't kill him,...
The lamb might have something more going on than just not eating. I had a lamb last year that was a week to two weeks old and stopped nursing and had bad...
Hi HollY: AgAg was my hypothetical mind experiment, probably suggested by Franna's Gotland semen :-). I am thinking that AbAg would be better as that has an ...
Hi Linda and all, I have two Ag ewes bred to an F1 gulmoget ram at Willow Garden South. I am HOPING for an At/Ag ram out of one of the two. At/Ag should be...
The problem here is this lamb has been on the ewe for 3 weeks and very few will switch to a bottle unless they have been getting one from day one. It might...
Hi Bill: I think that high multiples often come a bit sooner than "regular" twin gestation times. I may be looking for a test ram too. I am thinking that I...
Hi Gail: Sadly, no At in my flock. I expect AtAg has a distinguishable phenotype. Can you tell the AtAb phenotype on a reliable basis? AwtAt would need to be ...
Hi Bill: I think that high multiples often come a bit sooner than "regular" twin gestation times. I may be looking for a test ram too. I am thinking that I...
Hi Linda At/Ab is obvious, as the upper portion of the animal exhibits classic katmoget markings, but the belly and neck stripe are white rather than colored. ...
