Observational analysis showed increased milk production and rumen fermentation in dairy cows, suggesting fermented total mixed ration may enhance feed efficiency in hot environments.
Key Points
Milk production was enhanced with fermented total mixed ration, indicating improved feed efficiency under heat.
Cows consuming fermented total mixed ration had higher volatile fatty acids, which support energy metabolism.
The analysis involved multiparous Holstein cows, using a crossover experimental design with controlled dietary treatments.
Feeding fermented total mixed ration may provide a viable solution for dairy cows facing heat stress challenges.
