Agent to prevent wild animals from nibbling - comprising mixt. of copper powder, lactose and magnesium phosphate

摘要

The parent patent describes an agent for preventing wild animals from nibbling trees, fences, etc. comprises a feedstuff additive consisting of a ground mixt. of copper powder and lactose, the copper component being 0.01-1%. (pref. 0.1%.) of the mixt. In this addition, the agent also contains 0.05-50 mg magnesium phosphate per gram total mixt. Application of the agent in feedstuffs is considerably easier than application of previous agents which had to be sprayed on the plants etc. which are susceptible to damage by wild animals. The agent stabilises the bodily needs of the animals and supplies them with deficient substitutes (trace elements) which reduces their need to nibble.
