Today, we are going to discuss the dairy industry and how it has changed over the years. Have you ever hand-milked a cow? Or churned your own butter? For generations, hand-milking and churning butter were routine chores on farms across America. Over the last 250 years, advancements in equipment, genetics, and animal care have revolutionized the dairy industry.
Dairy cows themselves are highly efficient animals. They are one of the most efficient livestock animals that we have. Over the years, we have continued to maximize their productivity. According to the Dairy Herd Management, “The modern U.S. dairy cow is a biological marvel. Compared to her midcentury predecessors, she produces five times more nutrition while using 65% less water and requiring 90% less land.” In other words, they produce more with less. Today, on average, one single Holstein cow can produce between 23,000 and 28,000 pounds of milk a year. These numbers were obtained by breeding for superior genetics, specialized nutrition, improved animal health practices, and innovations in dairy management. The dairy cow became a specialized animal rather than the multi-purpose bovine of years past.
One of the most notable changes in the dairy industry is the way that we milk. Everything used to be done by hand. In the 1800s, the use of the Mehring Milking Machine revolutionized the way that we milk cows. According to the Museum of the Grand Prairie, “Mehring’s machine could milk two cows at once. A cow stood on each side of the machine with the seat toward their heads and the pump adjacent to their udders. While seated, an operator pushed the pedal bar back and forth to create suction.” We moved from tie stall milking to parlor style milking, where the technology continued to advance. Introducing a suction apparatus for each teat on a cow. Today, we have advanced so far that we have automated milking machines that require little human labor and can track total milk volume as well as the yield from each individual quarter of the udder.
The number of dairy operations has also changed. According to Georgia Milk Producers, Georgia currently has 67 dairy farms. According to the Dairy Alliance, in 2021, five years ago, Georgia had 130 dairy farms. Morgan County currently has 5. Even though we have so few farms, we are ranked 5th in the state for dairy production, according to the 2024 University of Georgia Farm Gate survey. This just goes to show that even though the number of operations has decreased, production yield continues to increase due to production efficiency and technological advancements. 🐮🧀🍶🚜🐄
