Healthier cows may produce more bioactive compounds in colostrum

Published: October 15, 2014
Summary
Dairy cattle with enhanced immune responses not only have lower incidents of disease, but may also produce more bioactive compounds in their colostrum that are critical to newborn calves and are beneficial in fighting mastitis-causing pathogens, an Ontario Veterinary College (OVC) graduate student has found. Research has shown that High Immune Responder (HIR) cows have a lower incidence of dis...

Very interesting, thanks. Could you also see differences due to parity in production of these bioactive compounds in colostrum and could you hypothesize about transfer of these to blood of calves?

Interesting stuff. However, significant difference does not tell me how much difference. How much higher immunoglobulin G levels were found in the high AMIR cows compared to low AMIR cows. What percentage of cows were found to be AMIR high versus low. Any difference in AMIR status between heifers and higher parity cows? I would expect more high AMIR cows in higher parity cows and if that is the case then it is not really news that AMIR status influence colostrum quality.

To All; Thanks for study. However, to reach the aim of Fleming's thesis is necessary to intake in sufficient quantity and quality colostrum in time by newborn calves.

Good luck!
