While doing some leisure reading I ran across this article and thought I would pass it on with the following questions.

optimize a calf's immune system
http://www.progressivedairy.com/index.p ... &Itemid=76




To boost passive immunity, dairymen have relied on high volumes of "good" quality colostrum administered to the calf within the first few hours after birth.

This practice has worked fairly well, but recent research and development by a Wisconsin company has demonstrated a program that can address passive immunity significantly by making the "best" colostrums even better with the addition of specific IgG's.
Absorption of IgG's in the first few hours of life is very important. However, IgG's that are not absorbed are effective at binding potential pathogens in the gastrointestinal tract and upper respiratory tract. IgG's can be delivered orally and intranasally at times when the animal is subjected to stress or exposed to potential pathogens with good effect.

My questions are, has anyone ever used an intranasal product and was it effective?
Would you consider using a intranasal product in your newborn program?
Thanks
