My grandmother was sitting with me at a table in the dining room of the nursing home where she was living at the time. She was over 100 years old, but still mentally sharp.
To distort a quote from the George Attla movie mentioned in a previous post on this blog: between what she knew and I knew, we got it figured out!
Furry and feathered animals like dogs and chickens have a higher dietary requirement for the sulfur containing amino acids, methionine and cysteine, typically limiting factors in the growth of hair and feathers.
In large commercial chicken farm factories hydrolyzed feathers are added to the animals’ feed formula for the above reason. The acid digested chicken feathers are bought from the chicken slaughter houses and processors, that is, recycled.
Around the time of my grandmother’s astute remark I bought 300 kg of hydrolyzed chicken feathers to feed to dogs. It was cheap. I never used much and this morning put the remainder out on the compost pile. I had forgotten it was there in the corner of the feed room.
Purely random coincidence, I read in the science news yesterday that one of the first signs of dementia and Alzheimer’s disease is impaired taste and sense of smell. Elizabeth McCann (Rogers) at 100 years of age did not have that.
After lunch that day a group of students from the local school were introduced to serenade the senior citizens. They started in on “Don’t tell my heart, my achy breaky heart…” Grandmother was irate at being forced to listen to this moronic earworm song. “No, no, stop! Take them away,” she muttered.
By the way, among her favorite foods were pork, eggs, butter, applesauce, and apple pie made with lard crust. She also was so addicted to coffee that she sometimes had to boil up a new pot at 2 AM to be able to get back to sleep.
Remember now kids, coincidence and association are not causality.
