I've never made and any bait before and I'm wanting to give it a try. I have some beaver,bobcat,castor and BTO. I am wanting to make a fresh,no taint, palatable bait. I am not trying to replace lures. I just want something in addition to lures that will keep the animal at the set as long as possible. Any suggestions on how much BTO and castor per gallon I should start out at?

BTO is hardly palatable IME.
Where did you get the recipe?
Some ones guide book? or a local fellow?

Always been told that animals prefer a taint to their meat for easier digestion you might want to check on that plus if they can’t smell it they might not find it as easy.

I didn't get a recipe, it's what I have from this season's catch.

Law Dog I plan on using this as well as lure

Here's my opinion (its free so you can take it or forget it)
Bobcat meat doesn't have much attraction by itself from my testing
Never tested beaver compared to other meats, some say it works some that I know have tested it say there's better meats
I believe Carmen stated castor is over rated for canines and I kind of agree, I little as a subtle side odor in a formulation or two is good.
BTO I've only tested one time in four or five sets and didn't impress me but it might have been the quality of the stuff I bought (have not been impressed with other ingredients ive bought from this company) I got some stuff im sure is not cut I plan to test here soon.

If your looking for a cheap simple bait that they will eat and works pretty good try sardines. There are other good simple baits you can get your hands on if your willing to use your imagination and do some testing to let the coyotes tell you what is good.

There are a handful of books that have instructions in them. Might be worth it to buy a couple of them too.

Split the batch and see what one you like the best when your done maybe both will work for you maybe one early one late. Some of the best lures out there today stink.

Thank you for the feed back !

Beaver works for me only if it's fresh and even then limited success, tainted works better for skunks. BTO has little or no success for me either. Made up some bait last year using tainted cat with some castor and a little bit of skunk quill, been satisfied with the results. Also made a batch using tainted horse and castor with nice results. Now having said that, I can't say I would have the same results next year as things change and no two coyotes are the same in my opinion. Suggest you make a few small batches and test them with a few fake sets using a trail camera or two to see what kind of results you get from them. Also weather and time of year can effect your results too. What works good in the summer may not work well later in the season and visa-versa. I'm no expert bait maker by any means and still have a lot to learn but earlier this season had very good luck with fresh or mildly tainted deer liver. Making up a batch for trial this summer. Good luck.

Thank you for the feed back 20scout!

A slight taint on any meat makes it work better in my opinion. If you add other ingredients to the meat, do it very sparingly. Keep track of the ingredients and where you use them. See which ones work the best. Castor is great, but I haven’t used bto. You can always just add castor or bto at the set instead of in the bait if you wanted.
