Bone Sauce

Postby George Collins » Wed Feb 29, 2012 12:10 am

Dippel's Oil (sometimes known as Bone Oil) is a nitrogenous by-product of the destructive distillation manufacture of bone char [1]. This liquid is dark colored and highly viscous with an unpleasant smell. The oil contains the organic compound pyrrole. It is named after its inventor, Johann Conrad Dippel, who lived in the Castle Frankenstein and is said to be the influence for Mary Shelly's "Frankenstein."

Dippel's oil had a number of uses which are now mostly obsolete. These included medicinal uses,[2] use as an alcohol denaturant, as an ingredient in sheep dips, as an animal repellent (tradenamed as "Renardine"), as an insecticide, and as a chemical warfare harassing agent. By not being lethal, the oil was claimed to not be in breach of the Geneva Protocol. During the desert campaign of World War II, the oil was used to render wells undrinkable and thus deny their use to the enemy.[3][4]'s_oil

And here is a recipe for making Dippel's Oil, aka Bone Oil, aka Bone Sauce:

The next project on the list is to manufacture some to protect all of the newly planted fruit trees.

I have seen a thread about this stuff on another permiculture site. I think it said that Sepp claimed that it worked to keep deer away for 10 years. That claim amazed me because I felt it would wash off or ware off befor that long. But I am not one to argue with Sepp, so I must last a long time on the trees. I would say try it and see how well it works, it is cheap to make and only takes a day to make. I am guessing that it smells pretty bad, so be careful how close to the house you use it at 1st. Let us know how well it works to keep the deer away from your fruit trees. I would be very interested to hear about your process of making it and how well you felt it worked for you.
Never doubt that a small group of dedicated people can change the world, indeed it is the only thing that ever has.

I will keep everyone updated on the results. I had supper with Youngblood tonight and told him about it. He was very interested in it as he has waged many battles against deer. He has tried every thing he has ever heard about to keep deer out of his crops and each and every one failed except for fencing his garden in with concrete reenforcement wire. The method of application that I envision is painting the bone sauce onto the trunks and limbs of the at risk trees. But as we sat around the supper table, a thought occurred - What would happen if one were to dilute it sufficiently to allow it to be sprayed onto a crop via a pressurized sprayer?

Might be something we try also.

When we returned home, I did an additional spot of research and found this:
Title: Rope test may indicate efficacy of tail-biting treatments in growing pigs
Author(s): Bracke, M.B.M.
Source: Animal Welfare 18 (2009)3. - ISSN 0962-7286 - p. 263 - 266.
Department(s): Wageningen UR Livestock Research (Animal Sciences Group) (2003 - )
Research programme(s): Outside graduate schools
Type of publication: Refereed Article in a scientific journal
Year of publication: 2009

Abstract: Tail biting is a most serious welfare problem in pigs raised for slaughter. In instances of an outbreak of tail biting, scientists have recommended that farmers take measures such as removal of affected animals, provision of enrichment materials and application of repellents to the pigs' tails. However, no scientific study has ever confirmed the efficacy of any of these suggestions in counteracting an ongoing outbreak. Here, the efficacy of two repellent ointments, Dippel's oil and Stockholm tar, were examined in a tail-chew test. For this, a novel piece of nylon rope was used as a tail model to measure biting behaviour semi-automatically in 24 single-sex groups of growing pigs (total 264 pigs). Repeated measures analysis showed no effect of time, gender or unit (12 pens per unit), but a highly significant effect of treatment, in that both Stockholm tar and Dippel's oil significantly reduced rope manipulation compared to controls. These results suggest that Stockholm tar and Dippel's oil may be effective in reducing tail biting. The approach taken may be valuable in further testing of strategies to reduce tail biting and improving pig welfare

I'm thinking that if it'll keep a hog from chewing on something that he otherwise would have, can there possibly be a stronger testimony short of personal experience towards establishing its efficacy?

I'll be interested to hear how it goes for you George. It kinda creeps me out from here, so I imagine it's gonna keep the deer away.
