Corn Steep Liquor Powder: High-quality fermented feed ingredients

1: Why do we need to ferment feed?

In the production process, feed cost accounts for about 50% of the total cost and is the main consideration affecting production; therefore, fermented feed with high nutritional value has broad economic prospects.

From the perspective of production cost, fermented feed can obtain greater profits due to its low raw material price and high nutritional value; feed fermentation can change the physical or chemical properties of low-value feed, improve the nutritional value and bioavailability of agricultural and sideline products. Therefore, feed fermentation is an economical and efficient method to convert base material raw materials into high-value-added feed products.

2: Corn Steep Liquor powder is rich in nutrients

Corn Steep Liquor powder is cheap and nutritious; it contains 43% protein, 35% amino acids, 7% organic nitrogen, 31% carbohydrates, 21% lactic acid, rich B vitamins, various minerals and other nutrients, PH4.5; the easily absorbed protein mainly in the form of amino acids and small peptides is easily bio-available. The organic acids such as lactic acid it contains can have a positive effect on the intestinal flora of animals, thereby improving the digestibility of corn gluten meal and making it easier for animals to absorb.

3: Why is Corn Steep powder needed to be added to feed fermentation?

During the feed fermentation process, Corn Steep Powder provides abundant and easily accessible nutrients, such as protein, amino acids, vitamins and minerals, which can be used as fermentation substrates for microorganisms such as Bacillus subtilis and lactic acid bacteria, promoting microbial growth, increasing protein production, and enhancing fermentation effects, thereby improving the nutritional value of feed and producing higher-quality fermented feed.

In addition, adding Corn Steep Powder to feed fermentation can also significantly increase the number of live bacteria of microorganisms such as lactic acid bacteria in feed, thereby inhibiting the growth of certain pathogenic bacteria by producing organic acids such as lactic acid, and lowering the pH value. The lactic acid produced by lactobacilli and organic acids such as lactic acid contained in CSL itself can also give the feed a unique sour taste.

4: Effects of fermentation of Corn Steep Powder with corn gluten meal, soybean meal, etc.

Experiments have shown that by using Corn Steep Powder, corn gluten meal, soybean meal, wheat bran and other raw materials for feed fermentation, the nutritional content of the obtained feed is greatly improved; the soluble protein and small peptide content increased by 69.1% and 47.6% respectively, and the crude fiber and crude fat content increased by 69.1% and 47.6% respectively. and acid detergent fiber content significantly reduced. The pH value decreased from 5.2 to 4.3, and the lactic acid content increased significantly, reaching 125.9%. The number of viable bacteria of Lactobacillus and Bacillus subtilis increased significantly, reaching 2.6×10 6 and 1.1×10 5 respectively.

At the same time, the results showed that feeding this feed during the feeding process can increase the level of immunoglobulins, enhance the immunity of broilers, and thus improve the growth performance of animals.

In summary, the use of feed produced by adding CSL powder fermentation can reduce and improve feed digestibility, reduce morbidity, increase daily weight gain, improve feed digestibility, and reduce feed-to-meat ratio, which has extremely high economic value.
