Re: [blackbelly] scrapie testing
See, all my African sheep are resistant. And that's enough for me to know.To follow a Government enforced scrapie program, something very different. Wait and see.Johnes disease, which is spreading in Mexico in large and Caribbean breeds not able to cope with, much more important to look at. Can't see why BB then the market for blackbelly sheep will skyrocket..., as they are unable to produce even 1/4 of a good wool sheep in flock does. The parasite resistance story about BB and St Croix, I have had them here in large numbers ask the guys in Texas, running a 1000 head of ewe, which breed are parasite resistant. For to make money, with breeds available, BB would never work.With Texel hybrids you make just 3 times the money, as they are able to handle the parasiste much better. I still have 10 year old Texel hybrid ewes, giving birth in November, and now an other set of twins. BBout of 600 head, may a 5 survived , the day we went out of drenching.With out medicamentation it is absolute impossible to run a larger herd of BB On no list you see such amount of problems as on the BB list, that should open our eyes and ask us, where to invest into the breed regards Helmut - Original Message - From: Carol J.

I agree, Helmut, that when it was just a question of complying with the government, I wasn't very enthused about the testing. Why should I spend money testing for something that our sheep don't get? However, my interest perked up when I started reading that blackbelly sheep might have a very unique genetic resistance to scrapie. In basic marketing terms, if we have something that no one else has, and everyone wants it (especially if the government is telling them they have to), then it would be to our advantage to figure out why we have that something and then figure out a way to capitalize on selling it to the have-nots. Part of learning whether or not blackbelly sheep have a unique genetic scrapie resistance involves learning the genetic makeup of our sheep, and that requires that we test them. The more of us that test our animals, the more data we have. And if that data indicates a uniqueness in our genetics, then we will have an easier time getting one of the researchers interested. If, through research, we learn that our sheep have a magic bullet in their genetics, then the market for blackbelly sheep will skyrocket. That's my logic, anyway!

Re: [blackbelly] scrapie testing/Johnes Long
I got sort of heckled off the Shedders list for bringing up mineral imbalances as causes for certain health problems. I got scoffed at because I might be reading Pat Coleby's books on natural animal care. Well, I do read Pat Coleby and she was the one who alerted me to the lack of copper in the diet as a cause for lack of resistance to a lot of diseases, including Johne's and parasites. My flock was suffering from a lot of low grade health issues. Some of those issues got pretty serious. The vets just kept saying worm 'em. Treat 'em for cocci. I dunno. These are lousy sheep. They're always dying. THREE vets couldn't make my sheep well. With a lot of trepidation, I mixed up Coleby's mineral lick which is blue with copper sulfate, but which has other minerals that buffer the copper. The sheep broke out in a war over the mix. When each in turn had gotten a tiny amount they pretty well ignored it, though they would go to it occasionally, dab their tongues in it, then go away. At this point, I went through a lot of agony, thinking I had poisoned my flock. But instead, I saw an abrupt end to virtually ALL the problems I was having. One lamb I was calling Rat Boy because he was so scruffy, is growing up into a gorgeous wether. And the really wierd thing is looking at fecal samples under the microscope. At a time when the ewes should be shedding eggs like crazy, there is hardly one. But what I have seen, is a nematode-like thing with one end blown out. Several of them. Maybe they get parasites, but their boosted immune system kills them??? Copper boosts the immune system and Coleby cites instances where farmers have bought Johne's bulls, put them on copper sufficient pastures and never had another symptom. It's all anecdotal, certainly not scientific. But we are CONSTANTLY being told not to give copper to the sheep without regard for what's actually in their feed. I analyzed all our feed and found out that the hay (including alfalfa pellets) is all sub-par for sheep in copper. But the BIG problem is that there is too much molybdenum. The ratio should be 6-10 parts copper to 1 part moly, and we were typically getting 2 parts copper to 1 part moly, when the copper wasn't adequate to begin with. In one alfalfa pellet sample we got 2X the TOXIC level of iron. There is too much potassium, which ties up the magnesium, which is probably why grass tetany is such a problem. It's not a lack of magnesium, which is adequate, it's way too much potassium. On all the hay samples the iron was way too high. But interestingly, our new crop of hay is off land that has not been chemically farmed in many years. A lot of the values are still off, but the iron content of the forage is 1/4 of the chemically farmed hay, just .04 above the upper limit for sheep. The hay came from a field about a mile away from the high-iron field that has been chemically farmed. Good for my sheep, bad for the hay field - All the nutrition from that field left that field and came to mine, where it will be run through the sheep and horses, and then enhanced, as compost, will go to nourish MY pasture, MY sheep all over again. That field will never be replenished and will eventually give out because all the nutrients are being transported off of it, never to return. I think that all this sudden susceptibility of animals to immune deficiency diseases like Johne's is a direct result of the degraded soils and the garbage the animals get fed in the feed lots. Ground chicken feathers? From chickens raised in factories? We're all blaming the animals and ourselves for selecting for one trait while disregarding another. When are we going to start looking at the soil??? Even humans are falling to new diseases every day. You can't go a day reading the newspaper without some new disease being reported. Does it have something to do with growing up at McDonald's, eating cardboard pizza and TV dinners? Tomatoes that ship rather than nourish? You can get three times the hay off a field that's been chemically fertilized, but that means its stripping three times the available minerals out of the ground at the same time - minerals that aren't being replaced by triple-16. You've got lignin and cellulose and artificially created protein - and all the heavy metals and crap that came with the fertilizer. The vital natural elements that create health are going, going, gone. I think our blackbellies have a HEAP of resistance to all sorts of stuff. But they are a product of the earth and the grass, just like we are. ALL our health starts right under our feet. We ARE responsible for bringing robust animals into the world. But all the genetic health on the planet, rolled into one animal, is a waste if the animal doesn't have one basic element to survive. Interestingly, it takes LESS selenium to kill a sheep than it does copper. The requirement for selenium is less than 2
Re: [blackbelly] scrapie testing
Very good information, thank you. But: They seem to do better on forage that the woolies do not fare well on. Working with a few thousand hair sheep in different breeds, and on side a 300 wool sheep in different breeds, no way that the average hair sheep even would come close to the production of the woolies. What has to do with the small number of hair sheep which are on the market, genetically too close. How do you like to compete against a Ile de France, where a Government did invest many Millions of Dollars to improve, against a St Croix, where no money has been invested ? St Croix on our ranch do not survive under normal management more than a 5 months, or I have to use medicamentation.But steady I read article of farmers with small and well protected flocks, how parasite resistant those sheep are.And that is not true once the flock is crowed and under stress. And about hot climate?Mexico imported large numbers of Ile de Franc, and they do in hot climate extreme well. And Mexico imported more than a 100 000 hair sheep, of very resistant type. I see Mexico producing lamb for US in large scale very soon.High quality wool/hair hybrid lambs. The Mexicans invest in meat production, and that's where we don't look at enough. About ...Big Brother but there are some things we just cannot try to get under the radar with.. most of the large Texas sheep breeders wrote me, that they have been forced in the scrapie program. I have seen one thing in my live, where ever the public did adapt too much to the government orders, country in short time in dept. See Germany , as example, always head down and they do what the Government is telling them.No money in the country. Switzerland? One the Government did artificial bring the price for butter up, the Swiss did not eat butter for a year.After that the Government gave up and butter was even cheaper than before.

Are we not trying to breed out the influence of other breeds in the BB? The AB, by accidental design, is a mixed breed, with many of the physical characteristics of the original BB. There are SOME AB breeders wanting to breed for more than just trophy horns-- overall structure, carcass quality and genetic health being their goal. And that is how a pure breed gets established-- careful genetic manipulation by controlled breeding. I know that is the purpose, supposedly, of everyone that joins the BB consortium. I sit and watch other sheep forums, as well, in order to learn more about sheep in general-- and I see the same types of issues, in perhaps the same numbers, on them, with the woollies and other hair sheep. The purpose of a hair sheep is NOT to produce wool-- it is to produce meat--on the forums where several breeds are covered, it is unanimous that hair sheep cost less to raise to maturity/slaughter. They seem to do better on forage that the woolies do not fare well on. And of course, being from warmer climes, the hair sheep are readily adapted to our warmer areas-- and in the colder ones, they do grow a protective winter coat-- here in the US, a lot of wool goes to waste. What is sold is sold to a small market of hand spinners and knitters. the market is very tight-- so much so, that I have noticed the prices on the alpaca products dropping like lead bricks!

We have to test/be in a program if we want to be able to particiapte in anyimprted semen program-- so we grit our teeth, and particiapate-- not willingly, but we do. And yes, Johnes is a much more serious thing to be worrying about-- but we do need to be able to rake advantage of any fresh genetics we can get further down the road. Of course, we can help keep resisteance in our flocks by minimizing the chemical interventions we make. We can cull poor lambing ewes, por mothers, etc. Unfortuneately, the genetics game is an expensive one--I priced the cost of the basic equipment to start the genetic screening process, and I do not believe any of us in the BB, or even the AB, have 10 Thousand USD, to spend on just part of the process!! (That does not include the fees to license the use of the equipment) And, to top it off, the equipment I found was not even geared towards sheep--probably making the cost even higher for such a specialty testing program. many of us here do not like Uncle Sam playing Big Brother but there are some things we just cannot try to get under the radar with..

Re: [blackbelly] scrapie testing/Johnes Long
Don't like to border too much with my writing. But for years, and Carol remembers that, I tell one thing: Blackbellies need much more copper, up to three times more than wool sheep. For example, with a copper level where a BB just drives well, a Texel would die in a time of three weeks. Now, if you select BB or AB with out sufficient copper , than you select just to the opposite . You create over the years a sheep which is much similar to average breed.The african or caribean type of sheep need a lot of copper and zinc to developpe parasite resistance. So the selection should be, as much copper as possible, to see which lines are able to handle that. And once you have the lines back , the gentics which can handle lots of copper, than you have as well the parasite resistance.Wool sheep do not need the copper for parasite resistance, as long as they have baltic blood. Last year we decided to feed the same feed to cattle ( 60 heads) as to our sheep. You know what happened to us? Plenty of lambs, the ewes are rebreed shortly after birth and lambs are coming and grow well. Cattle? Only one calf survied, they could not handle the spoiled silage. 15 years of harsh selection in sheep made the sheep way harder and healthier than my cattle. Why? Because in the first years, our cattle have been much better in regarding health than our sheep.So I did not cull so hard.. regards Helmut - Original Message - From: Barb Lee [EMAIL PROTECTED] To: blackbelly@lists.blackbellysheep.info Sent: Saturday, May 27, 2006 9:04 AM Subject: Re: [blackbelly] scrapie testing/Johnes Long I got sort of heckled off the Shedders list for bringing up mineral imbalances as causes for certain health problems.

Once the animal is raised in large number, only the best survive. That's why the African sheep, always in contact with wildlife, are extremely resistant and able to survive in difficult terrain. Only those imports which came out of large flocks, herds over a 3000 heads, did survive here in our climate.

Re: [blackbelly] scrapie testing
While what you say about only the best surviving difficult environments has merit, I believe there are better ways to select for resistant sheep than overcrowding them. Such as culling the ones that need deworming or frequent medical assistance. I don't know the genetics of all the sheep we hear about on this list, nor do I know all that much about the American Blackbelly or Barbado. But I believe that the Barbados Blackbelly, which is closer to the original African animal than the American Blackbelly, is hardy and much more parasite resistant than most wooled sheep. I see no reason why good pasture management and multispecies rotational grazing without either overcrowding or medical intervention would select for fragility among BB sheep. In fact, the multiple species aspect may well simulate contact with wildlife as happens in Africa.

Re: [blackbelly] scrapie testing
I've managed to learn the magic words that will help us locate other labs to do non-jugular blood collection for scrapie testing. The words are FTA cards. A quick Google search taught me that alpaca breeders use these as a requirement to prove parentage for registering their alpacas. Then I learned that the cards used to collect the blood are called Whatman FTA cards and can be purchased from the major lab supply companies (Whatman, Fischer Scientific, etc.). But then I struck gold when I found the Web site for Genaissance (http://www.genaissance.com/products_services/scrapie.html).

All of the APHIS-approved scrapie testing labs (http://www.aphis.usda.gov/vs/nahps/scrapie/app-labs-genotype-test.html#labs ) will do FTA cards, so the next step would be to work down the list and do some price comparison. When you talk to them, ask if they will do cotton swab samples and what surcharge, if any, they apply.

Re: [blackbelly] Scrapie Testing
GeneCheck is pricey, so you might want to just have them test Codon 171 ($11.00). Make sure they can report the K allele at Codon 171 if they find it (it's relatively new and VERY important). The K allele imparts the same folding pattern as the R allele and may result in the same scrapie resistance. A researcher at Oklahoma State University is also looking at Codon 136. Also, you don't HAVE to have a vet draw the blood, but good luck trying to do it yourself. Once you get the knack, it's easy, but so far, I haven't had any luck. I'm researching a couple of other blood-collecting methods. Premier sells an ear tag that collects blood in an ampule as the tag is applied. (But our poor sheep just don't need another tag in their ear.) And I'm looking into a blood-collecting card that comes in a roll with a peel off back. You peel of fthe back, get your drop of blood on it, and stick it onto a barcoded strip that you label with the sheep's ID number. I'll let everyone know when I learn more. Also, ASI has a program to help shepherds offset the cost of genotyping. I haven't used it myself, but the ASI Web site says they will reimburse the producer up to $14 for genotyping. Since GeneCheck only charges $11, it could very well be that the test might be free, so it might be worth checking into.

You collect cell samples on a cotton swab from the inside corner of the eye and put it in a labelled snack-size baggie. They check all three codons for the same price and you get a certificate back. That's nice when selling breeding stock. I have no idea if they would negotiate on volume pricing. They are hair sheep breeders as well as a testing lab. Peg Haese in SW Wisconsin __ Do You Yahoo!?

Re: [blackbelly] scrapie testing
Well I think I may go that way. To bad they are not an approved lab. I have called 2 vets close by and no one will pull blood on sheep so this will be a great benefit.

Re: [blackbelly] Scrapie Testing
Of the 21 rams I am testing 8 are 100% Barbados Blackbelly. Stephan your results of 25% QR have given me hope. If Virginia State ever has any QR Barbados Blackbelly rams available for sale let me know! It would really advance my program here! I will most certaintly keep you updated with my test results! I have no idea of how long it will take to get results back. I am finding out that I am not the most patient man. My progress has been limited to the use of QR sheep. I dream of the day I have a RR Barbados Blackbelly ram. The existence of 25% QR Barbados Blackbelly population would seem to imply there is around 6.25% RR Barbados Blackbelly sheep out there somewhere! My intentions are to join the voluntary srapie program as soon as I get R established in my Barbados Blackbelly flock. I see no reason to join until I am ready to close my flock.

It will be good data to add to our very limited information about how our breeds test in this area. Because your flock is a cross-bred flock, it could be that you end up with a higher percentage of QR/RR than a purebred flock. Our government's idiocy increases exponentially.

How many voluntary programs will become mandatory in the next 10 years? Consider all the government interest and involvement in tagging livestock. How soon before we are required to use electronic tags? ___ This message is from the blackbelly mailing list Visit the list's homepage at blackbelly@lists.blackbellysheep.info http://lists.blackbellysheep.info/listinfo.cgi/blackbelly-blackbellysheep.in fo ___ This message is from the blackbelly mailing list Visit the list's homepage at blackbelly@lists.blackbellysheep.info http://lists.blackbellysheep.info/listinfo.cgi/blackbelly-blackbellysheep.info
