Feeding heat-treated colostrum to neonatal dairy heifers: Effects on growth characteristics and blood parameters
(2009)
Newborn Holstein heifer calves were studied to compare absorption of immunoglobulin G (IgG1 and IgG2),
total serum protein concentration, lymphocyte counts,
health scores, growth, and starter intake after receiving ...
Effects of a prebiotic supplement on health of neonatal dairy calves
(2009)
Calf morbidity and mortality represent major financial losses for many dairy producers. The
primary cause of calf mortality in the U.S. is diarrhea caused by intestinal bacterial infections.
Traditionally, formulated ...
Evaluation of calf milk pasteurization systems on 6 Pennsylvania dairy farms

Waste milk has been fed to calves for many years, but
concerns with bacterial contamination as well as possible
transmission of diseases have discouraged widespread use
of this feed. Pasteurization of waste milk is one ...

Feeding heat-treated colostrum or unheated colostrum with two different bacterial concentrations to neonatal dairy calves
(2009)
The objective of this study was to determine the
effects of feeding heat-treated colostrum or unheated
colostrum of different bacterial counts on passive transfer
of immunity in neonatal dairy calves. First milking

Feeding colostrum with an esophageal feeder does not reduce immunoglobulin G absorption in neonatal dairy heifer calves
(2011-12)
Although the use of esophageal feeders
is commonly recommended to aid in
timely provision of colostrum to calves,
there are few published studies that compare
their effectiveness with other feeding
methods. Therefore, ...
Effect of heat treatment of bovine colostrum on bacterial counts, viscosity, and immunoglobulin G concentration
(2010)
A study was conducted to identify the optimal temperature
and time at which heat treatment of bovine
colostrum would least change viscosity and IgG concentrations
yet reduce bacterial count. First-milking
colostrum ...
