Episode 44: 2022 May Journal Club

Podcast Topic

Today’s episode is an installment of the Journal Club and is around an actual table once again! Our guests gathered at the Tri-State Dairy Nutrition Conference to discuss some of the newest research published in the Journal of Dairy Science surrounding reducing DCAD, nutrient digestibility and ammonia emissions from manure.

Timestamps

Dr. Lee stated that by reducing DCAD, the urine or lactating cows would have a lower pH, leading to reduced ammonia emission. Traditionally this leads to decreased milk production. (7:48)

Haley Zynda mentioned that there was milk fat depression across all three diets, even the high or average DCAD diets. (16:50)

Dr. Lee said their study saw a 15% decrease in ammonia, which is a significant environmentally beneficial benefit and increases the mineral value. (26:45)

Dr. Lee also mentioned that in this study, they saw a negative production effect, so at this time, it would not be economically viable. But over the next 5-10 years, we can improve upon the strategy and make it practical. (34:47)

Haley Zynda wrapped up by commenting the natural next step in research would be a field trial and trying to grow these crops, especially those using sulfur to decrease the DCAD and soils that are sulfur deficient. (50:09)
