Due to the fact that the majority of preweaned dairy calf mortality can be attributed to
diarrhea, or scours and to the fact that calf loss can be controlled by either treatment or
prevention of the illness, research focus on prevention has increased. Lactoferrin (LF), a
naturally occurring protein from milk, has proven antibacterial properties. It has been shown to
not only improve calf health, but calf growth as well. LF‘s ability to maintain calf health may
establish it as a preventative agent against calf gastrointestinal illness, including diarrhea in
calves.
Milk and colostrum contain the highest amounts of LF of any bodily secretion. Lactoferrin
concentration in bovine colostrum is approximately ten to one hundred times higher than in
mature bovine milk (2 mg/mL vs. 20 to 200 µg/mL). In comparison, human colostrum and
mature milk contain 7 mg/mL and 1 mg/mL respectfully.
The primary function of LF is supposed to be the inhibition of microbial growth.
Lactoferrin redu...ces the proliferation of bacteria by damaging the bacterial cell wall. While LF
is most active against gram-negative bacteria, it also displays some activity against grampositive bacteria.
Since the bovine milk has a low LF concentration, calves may benefit from supplemental
LF. Studies have been conducted with calves fed supplemental doses of LF in order to evaluate
its beneficial effects of supplementation to calf milk replacers (MR) or to whole milk fed
calves. LF has proven to promote calf health and performances in milk replacer fed calves.
Therefore, its addition to feed in the calf rearing process might have health and economical
reasons. However, additional research needs to be conducted in order to clarify LF‘s role in
different types of calf raising programs (esspecialy in calves feed whole milk), or during
periods of pathogen challenge.
