Research, Extension, and Education
Our group focuses on strategies to improve host resilience in neonatal calves and periparturient dairy cattle, the periods of increased disease risk in dairy cattle. We are particularly interested in interventions such as nutritional strategies or optimization of vaccination protocols that result in decreased antimicrobial usage on farms. The goal of our lab is to identify and test mechanisms that enhance immunity in calves and cows, thereby increasing their resistance to infectious diseases. The methods employed to achieve these goals combine mechanistic studies using cells or tissues in the laboratory with epidemiological studies in the field. Our current areas of active research include:
Dr. Abuelo serves as the Dairy Extension Veterinarian for MSU Extension. This appointment puts the lab in a unique position to continue having a close interaction with the Michigan dairy industry, communicate research findings, and identify new questions that need answers. All members of the lab participate and benefit from this interaction with Extension. Most of the research conducted in the lab takes place on commercial dairy farms, and graduate students are active participants in the extension/outreach efforts to the industry.
Similarly, our lab is committed to training the future veterinary agricultural workforce. As such, Dr. Abuelo coordinates the MSU continuing education program in Bovine Health Management, and the MSU Summer Food Systems Fellowship Program, targeting practicing veterinarians and DVM students, respectively.
- Determining the impact of oxidative stress on newborn calf vaccination responsiveness.
- Evaluating the utility of biomarkers of oxidative stress measured in the dry period to predict early lactation diseases.
- Modulation of oxidative stress via antioxidant supplementation and its impact on immunity and disease risk.
- Identifying the impact of dam late-gestation status on neonatal calf immunity.
- Optimization of vaccination protocols in calves and cattle to reduce the incidence of endemic diseases.

Abuelo et al. 2021
Our results show that feeding calves a second meal of colostrum within the first few hours of life has a positive impact on calf health and might have positive effects into the first lactation.

Abuelo et al. 2021
Our study showed that dry-off is a stressful event for dairy cows resulting in decreased rumination time for several days. Also, rumination time around dry-off was associated with some early-lactation diseases and, thus, could be a useful tool to identify at-risk cows early enough to allow for preventive interventions.

Cuervo et al. 2021
This study demonstrated that oxidative stress can compromise some immune responses of dairy calves that are needed for an efficient response to vaccination.
