A bottle of Grow and Shine apparently contains 946 ml (3 mg melatonin per ml). Roughly $60 per bottle unless you buy a bunch. At 25 cc per head per day, a $60 bottle would last one calf 37 days ($1.62 per day). That's cheaper than the implants for that period of time, but I guess I'll have to find out on effectiveness.
I sent an e-mail to Kirk Stierwalt last night. I think a very good question to ask him in his seminars is about supplements in general and his take on them and what they use: hair growth, "soundness" additives like glucosamine, etc. I'm guessing he'll refer us to Shag, but who knows.
I'm guessing he'll refer you to Shag, too, since his name's on it... shoot, his picture, even. I've not been a big fan of all the additives (seems like lots of snake oils out there), but we did feed Shag to our OKC steer this time, and I guess I'll say I'm a believer. I picked up a bucket at the Fort Worth steer show, and fed it through 'til yesterday, and I really think it helped alot with hair and bloom, at least. Without a cooler, we kept pretty good hair, and it grew a little all the way through. He never shed at all (you could rinse him and comb him all over and there wouldn't be a noticeable amount of hair left in the comb, and it was thick enough you had to use a skip tooth or fluffer) 'til the first of March, and very little after that (which was also after he was clipped for our county show), which is an accomplishment in itself to me. I wish we'd started it earlier - a friend of ours started it around Thanksgiving, and ended up with lots of really good hair, also without a cooler. As far as it's other claims (appetite, soundness, etc...) I don't know how much good it does, 'cause we didn't have any problems with that before we started, but I'll say we will be using it in the future.
Btw, Kirk might not be home from OKC 'til tomorrow night after the premium sale (obviously a problem we don't have - lol).
