A male researcher in a dark grey jumpsuit and blue gloves performs a veterinary procedure on a Holstein cow in a dairy barn facility.
Using a holistic approach that integrates basic and applied sciences, the Ribeiro Lab addresses the challenges of impaired transition cow health and subfertility at multiple levels, from farm management to individual cow physiology and tissue biology.
 
Our work has contributed to advances in dairy cattle reproduction, particularly in improving the understanding of normal embryo development and identifying deviations associated with pregnancy loss. In transition cow management, our research has highlighted the long-term implications of transition health for dairy production efficiency and farm economics.
 
A key focus of the program is the complex relationship between health and reproduction. Nutritional and pharmacological interventions are used to investigate physiological responses and their implications for animal health and fertility. Our findings are translated into practical management recommendations and innovations that support the sustainability of dairy production systems.
 
In addition to research, our group is committed to educating undergraduate and graduate students in the fields of Animal Health and Reproduction through classroom instruction, mentorship, and research training, as well as to disseminating scientific information to stakeholders and the broader public by working closely with academic institutions, scientific and professional organizations, and allied industries. This website and its associated media platforms represent another component of our commitment to knowledge translation and transfer to the public.

Research

Using a holistic approach that integrates basic and applied sciences, Dr. Ribeiro’s research program addresses the challenges of impaired animal health and subfertility at multiple levels - from farm management to individual physiology and tissue biology.

A fan-like arrangement of several printed academic research papers from the Journal of Dairy Science. The front-most paper is titled "Reproductive performance of grazing dairy cows following presynchronization and resynchronization protocols." The background is softly blurred, highlighting the stacked publications.

Publications

Peer-reviewed publications that disseminate the scientific findings of Dr. Ribeiro’s research program, contributing to advancements in animal biology and management.

Dr. Ribeiro stands on a stage, gesturing while giving a presentation. He is wearing a light-colored button-down shirt, jeans, a conference lanyard, and a headset microphone. To his left, a large screen displays a presentation slide with text and a colorful pie chart. Red curtains are visible in the background.

Outreach

Outreach activities that bridge research and on-farm application, delivering evidence-based strategies to enhance livestock management.

Teaching

Through innovative courses, Dr. Ribeiro has educated and guided thousands of students, helping to inspire future leaders in animal and veterinary sciences and shape careers in research and industry.

A student with long blonde hair tied in a ponytail, wearing green coveralls and blue gloves, stands in a dairy facility. She is looking at a digital control panel mounted on a piece of stainless steel machinery. In the background, the side of a cow is partially visible through the metal railings of the stall.

Funding

Competitive research funding provides resources for Dr. Ribeiro’s team and collaborators, supporting high-impact studies and hands-on training opportunities for students.

Lab students wearing work coveralls, rubber boots, and blue gloves walk together down the center aisle of a large, open-air dairy barn. To their right, several Holstein cows are lined up at a feeding trough with hay. One person in a green coverall holds a clipboard, and the group appears to be conducting a site visit or research task.

Opportunities

Dr. Ribeiro’s research group offers motivated students and researchers the opportunity to gain hands-on experience in advanced animal management and research methods within a collaborative, team-based environment. They also benefit from interacting with a broad network of academic and industry partners.
