The same ewe that lost lots of her wool last year while very pregnant is losing it again this year. I had thought it was a calcium deficiency. But this year I have had lots of mineral out and don't think that's the case.
Anybody have any ideas what else could be the problem?
what breed of sheep do you have? Do you shear them before you put them in breeding groups?
How old is the ewe? Is she scratching ( rubbing herself) against fences till there are raw areas or just loosing wool? I raise Icelandic and Katahdin sheep, so I have some experience in
both wool and hair sheep..
I'm sure you've already looked for evidence of raised, reddened skin or scratching and no lice detectable, here, wool loss it's a sign of sheep scab although I don't know whether that occurs in the US.
As it's happened twice during late pregnancy, were she here in the UK I'd be thinking nutritional deficiency, can you be sure she is ingesting the mineral? If you can be sure it still could be she is a heavy user or has trouble metabolising some minerals and trace elements while she is gestating. The other reason I can think of is stress.
I had a poke about after I last posted and it seems zinc deficiency can cause wool loss, if she's returning to normal after giving birth, it could be that or just the stress. Sounds like one of those odd little things that happens, is she young?
I sometimes think that sheep invent new things to worry the sheherd each year ;)
Have a question on sheep lice. All my Romney and Merino sheep(6) have now lost wool over their ears, tails, back of leggs and on either side of body. I found live lice crawling around. Have shorn them and did a saturation of Premectin 2. However, they are still losing wool. I've researched and haven't found info that will help. I'm told to do it again in 2 weeks. It is cold here in Connecticut and I have had to put nylon coats on them. They don't seem to be itching anymore but are still losing wool. Any thoughts would be much appreciated.
Thanks. I have been cleaning and spraying bedding and barn, as well. They do sleep in at night. The lice apparently jump from sheep to sheep in close contact. I'm wondering if it might be better to dust them instead of the pour-on method?
I had to ask my husband to go out and feed tonight as I was just too upset and couldn't see more wool missing.
