Randomized comparison between a forced air system and warm water bath for resuscitation of neonatal hypothermic calves with or without oral administration of caffeine.

Background: Hypothermia is a cause of neonatal calf death in cold climates. Practical and effective rewarming methods are important for bovine health within affected regions.

Hypothesis/objectives: To compare the rewarming rate and blood analytes (glucose, lactate, and cortisol) of calves resuscitated with forced air with warm water bath, with or without oral administration of caffeine.

Multicenter study of uterine tears and other reproductive complications in periparturient goats presented to veterinary teaching hospitals.

Background: Goats are increasingly popular as both production animals and pets. The frequency of and factors associated with periparturient reproductive complications in goats are largely unreported.

Objectives: (1) To report the frequency of periparturient reproductive complications in does presented to university veterinary hospitals and (2) to identify factors associated with uterine tears in the study population.

Comparison of turbidometric immunoassay and brix refractometry to radial immunodiffusion for assessment of colostral immunoglobulin concentration in beef cattle.

Background: Colostral immunoglobulin G (IgG) concentration is critical to the attainment of adequate transfer of passive immunity in cattle, however, studies comparing available tools for measurement of colostral IgG concentration in beef cattle are limited.

Objectives: To report the agreement between 3 commercially available tests for evaluating IgG concentration in beef colostrum.

Animals: Two hundred six beef-breed cows hospitalized for calving management or dystocia.

Comparison of turbidometric immunoassay, refractometry, and gamma-glutamyl transferase to radial immunodiffusion for assessment of transfer of passive immunity in high-risk beef calves.

Background: Attainment of adequate transfer of passive immunity (TPI) is critical to health of calves; however, studies comparing available tools for measurement of TPI in individual beef animals are limited.

Objectives: To report agreement between 4 tests evaluating individual TPI status in beef calves.

Animals: One hundred ninety-six beef calves born to cows and heifers presenting for calving management or dystocia.

Effects of endogenous progesterone during ovarian follicle superstimulation on embryo quality and quantity in beef cows.

Despite modifications in techniques and protocols used for multiple ovulation embryo transfer in recent decades, transferrable quality embryos (TQE) has remained relatively unchanged. The objective of this study was to evaluate the effects of endogenous progesterone during beef cow superstimulation on embryo quality and quantity. Thirty non-pregnant beef cows were sorted into 1 of 5 replicates and randomly assigned to one of two groups: High Progesterone (HP) or Low Progesterone (LP).
