The episode discusses the potential of sorghum as a dairy forage and recent advancements in its processing.
Sorghum costs less to plant and requires less water to generate productive tonnages. For years, sorghum has been ignored as a dairy forage, because the starch filled berry was nearly impossible to process, limiting the energy available to the cow. To combat this issue a male sterile bmr dwarf variety was developed with no grain head as an opportunity to harvest a nutrient dense, resilient leafy forage. Researcher Juan Pineiro, Associate Professor & Extension Dairy Specialist at Texas A&M AgriLife Research and Extension Center in Amarillo and his team substituted a portion of corn silage in the TMR with sorghum silage to determine the feasibility of this forage for dairy farms. The team found an improvement in dry matter intake which resulted in a nearly 8lb increase in milk produced when substituting 25% of the corn silage with headless sorghum silage. To compensate for the decrease in dietary starch, Dr. Pineiro added ground corn into the ration to balance energy. Additionally, Dr. Pineiro drew our attention to the recent advancements in berry processing for the non-sterile varieties. “We were able to see 0-1% intact berries remaining with the recently patented…
