Bypass Soy Protein MP

Rumen-Protected Soybean Meal for Dairy and Beef

Bypass Soy Protein MP is a rumen-protected soybean meal for high-producing dairy cows, cows in early lactation and beef cattle diets requiring additional digestible protein. With 458 g/kg crude protein, substantial rumen stability and exceptionally high post-ruminal digestibility, it provides a concentrated source of digestible protected protein for precision metabolizable protein formulation.

Independent evaluation by specialised research institutes established 82.48% rumen stability (BRE) and 99.60% post-ruminal protein digestibility (DVBE). With 362.2 g/kg undegraded dietary protein (UDP), 448 g/kg DVE91 and 454 g/kg PDIE, Bypass Soy Protein MP offers high evaluated protein values across different formulation systems.

Protein Quality Beyond Crude Protein

In ruminant nutrition, protein value depends on more than crude protein concentration. Rumen-degradable protein supports microbial protein synthesis when sufficient fermentable energy is available, while rumen-undegradable protein can contribute additional digestible amino acids after passage through the rumen.

Bypass Soy Protein MP reduces the susceptibility of soybean protein to ruminal microbial degradation. Its combination of rumen protection and post-ruminal digestibility can help nutritionists increase digestible dietary protein supply without relying exclusively on higher crude protein concentrations. The appropriate balance depends on the complete ration and animal requirements.

82.48% Rumen Stability: Measured Protein Protection

Bypass Soy Protein MP has a rumen stability (BRE) value of 82.48%, derived from an extensive in-situ/in-sacco rumen incubation protocol extending to 336 hours, conducted by an independent research institute using rumen-fistulated cows.

The 336-hour period describes the experimental protocol used to characterise protein degradation. It does not represent rumen retention time or mean that 82.48% of the protein remained undegraded after 336 hours. BRE must also be distinguished from calculated RUP or UDP values, which depend on degradation kinetics, passage assumptions and the protein evaluation system.

These measurements demonstrate substantial rumen protection and provide a technical basis for evaluating the ingredient in rations requiring additional digestible undegraded dietary protein.

99.60% Post-Ruminal Protein Digestibility

Rumen protection alone does not guarantee metabolizable protein supply. The protected fraction must also remain digestible after leaving the rumen. Excessive treatment can reduce ruminal protein degradation while compromising post-ruminal protein and amino acid availability.

Bypass Soy Protein MP achieved 99.60% post-ruminal protein digestibility (DVBE), measured using the mobile nylon bag technique in cows fitted with duodenal cannulas.

This demonstrates exceptionally high digestibility of the evaluated rumen-undegraded protein fraction. Together, the BRE and DVBE measurements establish the product's central nutritional characteristic: substantial rumen protection combined with exceptionally high post-ruminal protein digestibility.

DVE91, PDIE and UDP for Precision Formulation

Bypass Soy Protein MP provides 362.2 g/kg UDP, 448 g/kg DVE91, 431 g/kg WDVE, 454 g/kg PDIE and 442 g/kg PDIN. These values support professional protein formulation across different nutritional evaluation systems.

Its OEB91 value of -18 g/kg reflects the ingredient's calculated contribution to rumen nitrogen balance within the Dutch DVE/OEB system. This provides flexibility when balancing rumen-degradable nitrogen and digestible protein supply in the complete ration.

UDP, DVE91, WDVE, PDIE and PDIN are system-specific nutritional values and should not be interpreted as interchangeable measurements.

Controlled Maillard Protection

Bypass Soy Protein MP is produced through a controlled Maillard-based treatment using reducing sugars. The process modifies the susceptibility of soybean protein to microbial degradation in the rumen while aiming to preserve post-ruminal digestibility.

Careful process control is essential. Insufficient treatment may provide limited rumen protection, while excessive treatment can reduce protein and amino acid availability. The measured combination of 82.48% BRE and 99.60% DVBE demonstrates the balance achieved between rumen protection and post-ruminal digestibility.

Applications in Dairy and Beef Nutrition

High-Producing Dairy Cows and Early Lactation

High-producing dairy cows have elevated requirements for metabolizable protein and essential amino acids to support milk production and milk protein synthesis. During early lactation, dry matter intake may lag behind increasing nutrient demands.

Bypass Soy Protein MP can contribute additional digestible undegraded dietary protein when calculated metabolizable protein or amino acid supply is limiting. Inclusion should be evaluated alongside microbial protein synthesis, fermentable energy supply, dry matter intake and the complete ration.

Growing and Finishing Beef Cattle

In growing and finishing beef cattle, metabolizable protein requirements depend on body weight, growth rate, developmental stage and dietary conditions. Bypass Soy Protein MP can complement microbial protein supply when additional digestible dietary protein is required.

Compound Feeds and Protein Concentrates

Bypass Soy Protein MP can be incorporated into compound feeds, protein concentrates, complementary feeds and customised ruminant formulations. Inclusion rates should be determined according to animal requirements, complete-ration composition and the selected protein evaluation system.
