Corn steep liquor powder: high-quality nutritional supplement for ruminants

Corn steep liquor powder is extracted from fresh corn steep liquor and contains 43% crude protein, 35% amino acids, 7% organic nitrogen, 21% lactic acid, and 31% carbohydrates. It is commonly used in the feed industry as a protein source for cattle, sheep and other animals.

1: Corn steep powder can provide rich nutrition and improve digestion efficiency

The large number of microorganisms in the rumen of ruminants can utilize amino acids to synthesize proteins, fatty acids, and other substances, which is an important pathway for animals to obtain the required protein and energy;

Research has shown that amino acids in Corn steep powder can be utilized by rumen microorganisms; Adding corn steep solids to feed with urea as the sole nitrogen source can increase the production of microbial protein synthesized by rumen microorganisms through anaerobic fermentation; Thereby increasing the protein supply to ruminants. Meanwhile, the abundant amino acids in Corn Steep Extract can also be converted into volatile fatty acids by rumen bacteria, providing the energy needed by animals.

Moreover, the amino acids in CSL powder can stimulate the cellulose decomposition activity in the rumen, enhancing the ability of microorganisms or enzymes to decompose cellulose. Experimental results have shown that adding CSL powder to roughage ration can significantly improve the digestibility of crude fiber, cellulose, and dry matter in lambs.

2: Corn steep powder can improve the nutritional value of plant residues such as straw as feed

People usually use urea treated wheat straw (UTWS) as feed for ruminants. But only 30% to 35% of the NH3 released by urea remains in the straw. And these N will be rapidly released after the feed enters the rumen, leading to rapid fermentation and excessive N production in the rumen, which in turn leads to low nitrogen utilization efficiency.

Adding CSL powder can improve the NH3 escape and poor fermentation of UTWS as feed in the rumen. Corn steep powder contains water-soluble carbohydrates that can improve fermentation efficiency; Adding corn steep solids to UTWS for ensiling can increase nitrogen fixation in the cell wall matrix, slow down N release in the rumen, thereby minimizing nitrogen loss and providing a more stable NH3 supply for rumen microbial growth.

The slightly acidic pH (4.5) of CSL also helps to enhance the NH3 fixation of UTWS during ensiling process.

3: Corn steep solids can be used in conjunction with molasses

Molasses are widely used as an energy source in animal feed. The combination of Corn steep powder and molasses can provide fermentable carbohydrates and crude protein, thereby enhancing rumen function; Provide sufficient nutrition for animals to sustain themselves.

Experiments have shown that corn steep solids and molasses can safely replace the concentrated feed in the diet, providing cows with abundant energy and protein; And it will not affect the feed intake of cattle.
