I had found a detailed Chinese study on lactoferrin in various stages of maternal lactation in various ethnicities and assorted regions. Then my Chromebook erased all my tabs and that page, and I only found this aummary.

It seems the earliest milk has the highest lactoferrin content and it lowers over time and stabilizes after the third month from birth. Now I will find some data on animal milk which is far lower in lactoferritin than human milk. I wonder if any studies have been done on the degree of illness in breast fed babies versus cows milk or factory formulas
https://viva.org.uk/health/a-comparison-between-human-milk-and-cows-milk/ While this study does not refer specifically to ferritin, there are some interesting comments under IRON. The chart comparing vitamin and mineral content of cow and human milk is also of interest.
Human milk is rich in lactoferrin, with a concentration around 1–2 mg/mL [7–9], whereas lactoferrin concentration in ruminant milk is 10–100 times lower than in human milk (in the range of 0.02–0.2 mg/mL) [10, 11].Mar 19, 2014
This was the best (only?) article I found comparing lactoferrin in humans, goats, and cows.

Plenty of lactoferrin supplements on Amazon. Already got plenty Benadryl.

I had read hay fed cows have more lactoferrin in the milk than grass fed cows. Don’t ask me why. I try and drink organic grass fed cow milk. Same idea as with eggs, etc. I need to find a local farm for eggs.
