From chatGPT:

• Phosphorus Deficiency in Animals

  • Animals with low phosphorus levels may develop pica, a condition where they crave and eat unusual substances—bones, wood, soil, etc.

  • This is often seen in cattle grazing in phosphorus-deficient areas.

• Bone Chewing (Osteophagia)

  • To compensate, animals may chew on carcasses or old bones, which may be contaminated with Clostridium botulinum, the bacteria that causes botulism.

    • These bacteria can thrive in decomposing animal matter.
