Do you feed your cat a food that helps with human allergies? Did you know you have chickens to thank?

While i was on facebook today I came across some studies posted by The Association of Avain Veterinarians (AAV) about how exposing chickens to Fel d1, which is one of the most common causes of cat related allergies in humans, has them produce eggs that carried antibodies of that allergen in their yolks. When those yolks were then fed back to the cats the cats experienced a reduction in that allergen. This is lovely news for cat lovers with cat related allergies. I posted one of the studies below as its pretty interesting. Also shout out to the cat who was removed from the study for being fractious lol

Also specifically we have lab strain Leghorn chickens to thank as it seems like its usually leghorns who are used for these things, which makes sense since they are very productive layers and very genetically similar. Blue and Greenie distant relatives lol (Blue bird below for people who dont know what a leghorn is)

Reduction of active Fel d1 from cats using an antiFel d1 egg IgY antibody

Background

Fel d1 is the most important allergen from cats. Fel d1 is produced primarily in saliva and spread to the haircoat during grooming and then transferred to the environment via hair and dander.

Objectives

A novel approach to reducing allergenic Fel d1 exposure was evaluated, involving binding the Fel d1 with an anti-Fel d1 polyclonal egg IgY antibody. The hypothesis was that hair from cats who had been fed foods containing anti-Fel d1 IgY would show a significant reduction in active Fel d1 (aFel d1).

Methods

Hair collected from 105 cats completing a 12-week study was evaluated for aFel d1 via ELISA. Hair was collected four times over a 2-week baseline period, then weekly during the 10 week treatment period during which cats consumed a food containing the anti-Fel d1 IgY.

Results

Baseline aFel d1 (μg/g hair) varied greatly among the cats in this study. From week 3, there was a significant reduction in mean aFel d1 with an overall average decrease of 47% by week 10, ranging from a 33–71% decrease vs baseline. Cats with the highest baseline aFel d1 showed the greatest decrease in aFel d1.

Conclusions & Clinical Implications

Feeding anti-Fel d1 IgY to cats successfully reduced Fel d1 on their haircoat with the greatest decreases observed in cats with initially high levels. Feeding a diet with anti Fel d1 IgY significantly reduced the active Fel d1 on the hair of cats.
