Arm & Hammer Animal Nutrition will be sharing some exciting new research at the 2014 American Dairy Science Association Annual Meeting, July 20 – 24, in Kansas City, Missouri. Of particular interest are several studies, and their short summaries, listed below. Click on the abstract number to access more information; once on the page, scroll to the desired abstract.
We encourage you to attend these presentations to learn more about the research. Stop by our booth (#520) during the conference if you’d like to discuss this research further or if you have questions about the Arm & Hammer Animal Nutrition product portfolio.
Impact of DCAD on dairy cow feed intake, milk production, rumination and feed efficiency: This University of Maryland meta-analysis looked at data from 1965 through 2011 to determine if there is a linear response to DCAD over a wide range of studies. Results showed that for each 10-point increase in DCAD, there is a good likelihood of increasing milk fat percentage and total production, rumen pH, NDF digestibility and fat-corrected milk.
Effect of dietary fat source on milk production and milk composition in early lactation: This study from Washington State University found that milk production and milk fat production was similar for the two supplemental dietary fat sources examined—MEGALAC® and a fatty acid prill that was high in palmitic acid (C16:0). The results suggest that cows at different stages of lactation use individual fatty acids differently; the recommendation is to be sure to feed MEGALAC in early lactation.
Using potassium carbonate to increase dietary DCAD and improve dairy feed efficiency: This University of Maryland study set out to determine the optimal dietary DCAD level needed to maximize feed efficiency. Results show that increasing DCAD from +25 to +40 meq/100g DM resulted in linear increases in fat-corrected milk. Results also indicated that individual cows at about 100 days in milk or later and producing about 85 pounds of milk would likely optimize their feed efficiency with a DCAD between +30 to +40 meq/100g.
Effect of precalving dietary DCAD on milk production: A meta-analysis: Researchers in Australia and the United States explored the milk production impact of feeding a negative DCAD diet for 21 days prepartum. The results were significant and showed that cows fed a negative DCAD diet during this time frame produced 2.5 pounds per day more fat-corrected milk for at least the first 65 days in milk, equating to a minimum of 163.5 pounds more milk per lactation.
