SOY BEST

Nutrient Profile - CPM Compatible

The following nutrient profile is compatible with CPM, CNCPS and ration balancing programs that are based on CPM and/or CNCPS. To view the nutrient profile that is compatible with NRC and programs based on NRC, click here.

The process for manufacturing Soy Best® High Bypass Soybean Meal has been changed and improved with the addition of Gums (lecithin and phosphatidyl-choline). This has made it necessary to update Soy Best nutrient values for use in ration balancing programs. The new process increases rumen undegraded protein and is patented.

Documentation in support of these nutrient values has been published in the Journal of Dairy Science (J. Dairy Sci., 2005, Vol. 83, Supp. 1, Abstract #86, page 90) and in “Determination of Ruminal Protein Degradation Kinetics of Soy Best with and without Soy Gums to be used in the CPM-Dairy Nutrition Model,” by Dr. Luis Tedeschi, Texas A&M University.

SAMPLING AND ASSAY PROCEDURE

This update was supervised by the CPM Ingredient Library Manager. Ten, 50-lb. samples of Soy Best were taken representing two crop years (September through February) and many production runs. The total 500 lbs. of samples was sent to the Ruminant Feed Analysis Consortium at the University of New Hampshire. RFAC personnel sent five representative sub-samples to Minor Institute. The CPM Ingredient Library Manager then supervised proximate analysis at Cumberland Valley Analytical Services, amino acid analysis at the University of Missouri-Columbia and fatty acid analysis at Clemson University. Rumen bypass protein measurements were made at West Virginia University and intestinal digestibility of bypass protein was measured at the University of Minnesota. Rumen protein kinetics was investigated by Dr. Luis Tedeschi, Texas A&M University.

COMMENT ON BYPASS PROTEIN VALUES

The 73.3% RUP value reported by West Virginia University is for a 16-hr rumen incubation in a lactating cow. RUP values reported by the University of Minnesota are calculated from the natural log of nitrogen disappearance over time (Mather and Miller, 1981, Br. J. Nutr. 45:587). RUP values from these two different procedures are not comparable (Bach et al., J. Animal Sci. 1998. 76:2885).

Footnotes
† Fresh soy gums are applied to Soy Best under non-ambient conditions, resulting in elevated vitamin E and phosphatidyl-choline. Phosphatidyl-choline and methionine are both methyl group donors and phosphatidyl-choline can spare methionine for milk protein synthesis. Ration balancing programs in use today do not account for this important fact.

§ 16 hours in rumen (J. Dairy Sci. Vol. 83, Suppl. 1, Abst. #86, pg. 90). The protein bypass value for any ingredient is not a fixed number and will vary with dry matter intake, rumen solids retention time, rumen pH and rumen microbial population.
