Effect of heat treatment of bovine colostrum on bacterial counts, viscosity, and immunoglobulin G concentration
Elizondo Salazar, Jorge Alberto; Jayarao, Bushan M.; Heinrichs, Arlyn Jud (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 ... -

M.; Heinrichs, Arlyn Jud (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, ... -
Feeding heat-treated colostrum or unheated colostrum with two different bacterial concentrations to neonatal dairy calves
Elizondo Salazar, Jorge Alberto; Heinrichs, Arlyn Jud (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 colostrum ... -
Feeding heat-treated colostrum to neonatal dairy heifers: Effects on growth characteristics and blood parameters
Elizondo Salazar, Jorge Alberto; Heinrichs, Arlyn Jud (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 ... -
Heat Treating Bovine Colostrum
Elizondo Salazar, Jorge Alberto; Heinrichs, Arlyn Jud (2008-12)The syndesmochorial placenta of the bovine prevents transmission of Ig in utero and calves are born agammaglobulinemic. Consequently, ingestion and absorption of adequate amounts of colostral Ig are essential for ... -
It saves lives
Elizondo Salazar, Jorge Alberto; Heinrichs, Arlyn Jud (2008)Esophageal feeders are an effective tool to get colostrum into newborn calves. By following a few simple steps, a good employee can easily use it safely and, most important, immunoglobulin absorption rates compare favorably ... -
