Gene Edited Cows Thrive in Heat: Remarkable Farm Trials!

[00:00:00]The difference was [music] remarkable.

[00:00:01]This technology is no longer just an idea in a laboratory. It is now being tested on real farms and the results are very promising.

[00:00:11]Several key field trials took place in 2025 and into 2026, providing the first large-scale data on how these animals perform. [music] One major study was run by Tropical Resilience Genetics or TRRG in Australia.

[00:00:29]They placed gene-edited slick Holstein [music] cows into commercial herds. They also placed Jersey dairy cows into the same herds and compared their performance to standard cows during major heat waves.

[00:00:43]The difference [music] was remarkable.

[00:00:44]The TRRG data was clear.

[00:00:47]During the hottest periods, slick cows produced about 3 to 4 more liters of milk per day.

[00:00:54]The slick cows kept a better appetite and showed fewer signs of heat stress.

[00:00:59]They also had better reproductive outcomes getting pregnant again sooner after giving birth, a key driver of profitability.

[00:01:08]Some measurements showed methane emissions per liter were lower because the animals were more efficient.
