Well, it's not actual hair and feathers, it's an amino acid extracted from those sources. There is also fat, no mention of the source. I would think that fat would act like an attractant and its source important. If it is say chicken fat than one would think it less attractive than fish based fats and oils, which are natural to the fishes environment.
But just speculating.
