Process for modifying protein digestion of ruminant feeds and products produced therefrom

1. A process for increasing rumen undegraded protein in an animal feed comprising:

mixing water with a yeast biomass;

adding the water and the yeast biomass to a composition comprising canola meal, soybean meal, or a combination thereof and an alkaline crystalline solid selected from the group consisting of lime, calcium oxide, and a combination thereof, such that the composition has a moisture content of between 8-35% by weight and the alkaline crystalline solid reacts with the water and generates heat;

mixing the composition; and

heating the composition to a temperature of at least 100° C.;

wherein the canola meal, the soybean meal, or the combination thereof has an increased amount of rumen undegraded protein after the alkaline crystalline solid reacts with the water;

wherein the canola meal comprises at least 60% rumen undegraded protein and the-soybean meal comprises at least 55% rumen undegraded protein.

2. The process of claim 1 , further comprising subjecting the composition to increased pressure.

3. The process of claim 1 , wherein the process results in the reduction of glucosinolates and/or secondary metabolites thereof in the canola meal.

4. The process of claim 1 , wherein the composition further comprises cotton seed meal.

5. The process of claim 1 , wherein the composition consists of the water, the yeast biomass, and the canola meal, the soybean meal, or the combination thereof.

6. A process for increasing rumen undegraded protein in an animal feed comprising:

mixing a composition comprising canola meal, cottonseed meal, water, a yeast biomass, and an alkaline crystalline solid selected from the group consisting of calcium oxide, and combinations thereof, such that the alkaline crystalline solid reacts with the water and generates heat;

heating the composition to a temperature of at least 100° C.; and

drying the composition;

wherein the canola meal and the cottonseed meal has an increased amount of rumen undegraded protein after the alkaline crystalline solid reacts with the water;

wherein the composition comprising the canola meal and the cottonseed meal comprises at least 60% rumen undegraded protein.

7. The process of claim 6 , further comprising:

heating the composition in a device to a first temperature; and

subjecting the composition to a second temperature that is lower than the first temperature;

wherein the first temperature is the highest temperature of the process.

8. The process of claim 7 , further comprising removing the composition from the device.

9. The process of claim 6 , wherein the increased amount of rumen undegraded protein in the canola meal is between 69.0-76.6% expressed as a percentage of crude protein (CP).

10. A process for increasing rumen undegraded protein in an animal feed comprising:

mixing a composition consisting of soybean meal, canola meal, cotton seed meal, water, a yeast biomass, and an alkaline crystalline solid selected from the group consisting of calcium oxide, lime, and combinations thereof wherein the composition has a moisture content of between 8-35% by weight and the alkaline crystalline solid reacts with the water and generates heat;

heating the composition with steam;

wherein the soybean meal, the canola meal, and the cotton seed meal have an increased amount of rumen undegraded protein after the alkaline crystalline solid reacts with the water;

wherein the composition comprising the soybean meal, the canola meal, and the cotton seed meal comprises at least 55% rumen undegraded protein.

11. The process of claim 10 , wherein the increased amount of rumen undegraded protein in the soybean meal is between 50.0-65.5% expressed as a percentage of crude protein (CP).
