Good health
starts in the gut.
Bovamine® Dairy Milk Replacer
Supplement is a science-based
probiotic that is proven to:
* Promote the integrity and
function of the digestive tract
* Stimulate immune responsiveness
* Improve growth rate, pre- and
post-weaning

acute exposure to high THI damages cells of
the cow's digestive tract, allowing pathogens
and toxins to enter the blood stream. Cows exposed to high THI have impaired immune function, lower milk production, lower milk fat and
protein percentages, reduced dry matter intake,
poorer reproductive efficiency, shorter pregnancy lengths, and lower calf birth weights.
Ventilation
All animals require a constant supply of clean,
fresh air. Adequate ventilation removes excess
heat, moisture, dust, microbes, and gases that
accompany housed animals. Poor ventilation
is identified by observing condensation on curtains, ceilings and support structures, and increased moisture and ammonia concentrations.
Poor air quality can result in immune suppression and an increased incidence of pneumonia.
HANDLING
Proper handling is often called good stockmanship. Improper (or rough) handling of dairy
cattle is a psychological stressor which is characterized by fear resulting from new or unfamiliar events, pain, excessive noise, touch, and
visual experiences. Improper handling has been
shown to increase cows' fear of humans, while
gentle handling can reduce fear. Improper handling can result in both acute and chronic stress
which may result in reduced milk production.

TRANSPORTATION
The majority of research on the impact of
transportation on cattle has been conducted
with beef cattle. These studies have shown that
hauling cattle long distances can reduce dry
matter intake and average daily gains. Some
studies have also shown that cattle hauled long
distances have suppressed immune function
that may increase their risk of disease. We can
speculate that hauling dairy cows, calves, or
springing heifers long distances may also result
in reduced immune function.
CONCLUSIONS
Managing stress in dairy cows results in
healthier and more productive animals. Stress
in dairy cows is caused by stressors that can't
be avoided (calving and dry off) and also by
stressors that can be managed (feeding management, molds and mycotoxins, sanitation,
social stress, cow comfort, high THI, ventilation, handling, and transportation.) These
stressors affect immune function, health, and
production, and their economic effects can be
significant. For this reason, assessing the level
of stress on your farm and developing a plan
to manage stress can have a significant pay-off.
Which stressors are your cows facing? What
level of stress are your cows experiencing?
What plan do you have in place to manage your
cows' stress?
