I've got a three year old romney that of late appears to be down more than up. She was moved to new pasture about a month ago along with everyone else, and had been out there for a few hours a day prior to this permanant move. It's been quite hot the past couple days, so while I've kept an eye on her, I wasn't terribly concerned. She's alert, her eyes are bright, and gum color good (for a black sheep!) Yesterday evening she was up and grazing and not wanting to be messed with; I laid any concerns to rest, figuring it just the heat. This morning, not nearly so warm, and she was down again. Didn't make any move to get up when I walked over to her. Burping, chewing cud, no tight belly. Eyes and color still good, but just no desire to get up and move. She's been dewormed, but we're due for another fecal flotation, which I've been doing rather regularly since we've been dealing with coccidia. Her weight is quite good...actually could shed a few pounds after this month on pasture. Weight good over the top of her back, so doesn't look like a typical parasite case. Any thoughts? Could the additional weight be an issue?
