Where Agriculture, Efficiency, and Curious Cows MOOve Together for a Sustainable Operation

By Isamaris Aparicio González

The change of generations 

In Hatillo, Puerto Rico, a municipality known as “The Capital of the Dairy Industry”, Carlos Alberto Pérez Pérez, a 3rd generation dairy farmer and agronomist from the University of Puerto Rico, Mayagüez Campus, visits his farm every day with the desire to make a difference and the passion to educate and create a more efficient system for traditional dairy farming. His story with farming began with his grandfather, Don Benjamín Pérez, who started a dairy farm in 1974 and raised his family around it. Carlos' father followed the steps of his own, becoming part of the dairy farmer community, and now Carlos is committed to continuing the family legacy.

Carlos witnessed his father's unwavering dedication to dairy farming, to the point of being late to his own wedding to deliver a calf. "Fortunately, the one who waited at the altar was my mother and they have been married for 36 years", said Carlos as he described how farming became a passion for his entire family. Carlos’ farm “Hato Don Benja” is named in honor of his grandfather. It is a place where cows graze on 19 acres overlooking the Atlantic Ocean. Carlos’ Voisin style rotational grazing has led him to produce quality milk he provides for his family’s cheese industry, “El Casero”. To ensure quality, he performs genomic tests on his cows meticulously choosing them based on their performance potential.

Video: Genetics vs Genomics in Swine - Dr. Max Rothschild



In this episode of The Swine it Podcast Show Canada, Dr. Max Rothschild, Distinguished Professor at Iowa State University, explains how genetics and genomics have transformed swine production. He explores genomic selection, key gene discoveries, and the role of gene editing in improving disease resistance and productivity. Practical insights on litter size, meat quality, and industry adoption are also discussed. Listen now on all major platforms!

"Genetic improvement in swine production accelerated significantly once molecular tools enabled identification of DNA level variation influencing growth, reproduction, and meat quality across commercial populations."

Meet the guest: Dr. Max Rothschild / max-f-rothschild-b3800312 earned his PhD in Animal Breeding from Cornell University and has spent over four decades at Iowa State University advancing swine genetics and genomics. His research focuses on genetic improvement, disease resistance, and molecular tools for swine production. A leader in pig genome research, his work has shaped modern breeding strategies.
