I just stopped in to TSC to pick up some Durvet B complex. They told me (remember these are TSC employees) that they had replaced Durvet with the Aspen brand. This is what I found on the shelves, Aspen brand injectable B for cattle. Guys, it has NO Niacin. Don't let them sell it to you.
Someone on here reported a TSC employee saying that cheerios are a good niacin supplement. I wish they would just keep their mouth shut if they don't what they are talking about.
The guy at my TSC had no idea why I wanted it for my duck. I went ahead a gave him a 5 minute educational lesson while I was there. This was also the same guy that try to talk me into buying chicken feed for my duck. Let's just say he learned a lot this morning and was kind enough to offer me a job...
