DDGS Direct, DDGS Manufacturer

DDGS average total energy is about 5,530 calories per kilogram of dry matter (DM) or 2,514 calories per pound of DM. The total energy content is higher than corn. The energy digestibility in DDGS is less than corn. The measured energy digestibility. The digestible energy (DE) and metabolizable energy (ME) in DDGS are 4,140 and 3,897 calories per kilogram of DM (Pedersen et al., 2007). The digestible energy (DE) and metabolizable energy (ME) in corn are 1,882 and 1,771 calories per pound of DM (1).
Due to the conversion of starch into ethanol during the brewing process, DDGS contains only a small amount of cassava starch (2). However, the hemicellulose in corn cannot be converted into ethanol, so the chemical fibers in corn cannot be transformed into ethanol. The content of DDGS chemical fibers (such as acid and alkali washing chemical fibers and neutral washing fibers) is also relatively high.
DDGS contains approximately 0.60% phosphorus and has a digestibility rate of about 59% (table), whereas corn has a digestibility rate of only 21.5%, significantly lower than that of DDGS (Pedersen et al., 2007). The main reason for the phosphorus digestion in DDGS compared to corn may be the hydrolysis of some phytic phosphorus in the fermentation process at the alcohol plant, which produces a large amount of absorbable phosphorus. Therefore, if DDGS is included in the pig's daily ration, the utilization of organic phosphorus will increase, but the demand for inorganic phosphorus sources (such as dicalcium phosphate or monohydrogen phosphate) will often decrease. This not only reduces the cost of the daily ration but also decreases the amount of phosphorus excreted by small animals. Table 4 presents the standard carbohydrate content and ileal digestibility of carbohydrates from 36 DDGS samples from 35 different alcohol plants in the Midwest of the United States. The data in Table 4 shows that there are some differences in the digestibility of carbohydrates in different DDGS samples (Stein et al., 2005; Pahme).tal., 2006a&b; Stein et al., 2007; Urriola et al., 2007). This is primarily reflected in the lysine digestibility. Compared to other essential amino acids, the digestibility of lysine varies significantly across different versions (Fastinger & Mahan, 2006; Stein et al., 2006). Some of these differences are due to lysine in DDGS samples being damaged by heating, which reduces the digestibility of lysine in the samples (Cromwell et al., 1993). Aside from lysine, the digestibility of amino acids in DDGS is generally moderate, with variations across versions similar to other feed ingredients, within a normal range. To mitigate the risk of using DDGS with low lysine digestibility, the ratio of lysine to crude protein in DDGS should be calculated (Table 5). A low lysine digestibility in samples typically correlates with high lysine content in the samples, which is why the quality of lysine in the samples can be estimated using the ratio of lysine to crude protein. If the ratio of lysine to crude protein is 2.80% or higher, the DDGS quality is moderate to high, but if the ratio is less than 2.80, it indicates poor product quality. Since lysine is generally an important carbohydrate in swine diets, the ratio of lysine to crude protein in DDGS should generally not be less than 2.80%.

The core of the measurement should be the standardized ileal digestibility of lysine and other essential amino acids in 36 DDGS samples.
DDGS Purchase Guidelines
Due to variations among manufacturers, it is recommended that feed manufacturers test the nutritional content of DDGS before selecting it. To confirm the purity of the product, if soy hulls or body fat content is insufficient, it is generally advised to request a DDGS feed nutritional content guarantee from the supplier. The crude protein content should be at least 27%, with total body fat and nitrogen content of at least 9% and 0.55% (6). The content of weakly acidic washing chemical fibers and neutral washing fibers should not exceed 12% and 40%, respectively. To prevent heat damage to lysine in DDGS, the ratio of lysine to crude protein should be at least 2.80%. It is recommended that feed manufacturers obtain relevant information on DDGS mycotoxin levels before purchasing, as there is no guarantee.
6 Items to Inspect After Buying DDGS
Apply DDGS to formulate feed rations
When using formulated feed, it is recommended that the DDGS content be as close to corn as possible. The feed should be corn-based. DDGS serves as a carrier for standard ileal digestible carbohydrate and digestible phosphorus content. The protein in DDGS has a low lysine content, so an appropriate amount of crystalline L-lysine should be added to the feed. For growing-finishing pigs and lactating sows, when formulating feed, for every 10% increase in DDGS crystals, 0.10% L-lysine must be added. Additionally, in the formula of the feed, soybean meal can be reduced by 4.25% and corn by 5.70% (7). DDGS contains phosphorus and is digested in corn and soybean meal, so for every 10% increase in DDGS, the amount of calcium dihydrogen phosphate can be reduced by 0.20%, but the amount of sand should be increased appropriately to maintain an adequate calcium content. If the DDGS content in the feed exceeds 20%, 0.015% of crystalline L-glutamic acid needs to be added.
Compared to lactating sows and growing-finishing pigs, pregnant sows have a higher demand for digestible chromic acid. Therefore, when formulating pregnant sow diets with DDGS, the replacement of soy hulls is lower. DDGS has a relatively lower lactic acid content, so for every additional 10GS in the pregnant sow diet, the soy hull usage is reduced by only 2.20% to maintain an appropriate level of lactic acid in the diet. Consequently, if the pregnant sow diet contains 10% DDGS, the corn content (7) remains unchanged.

a If the usage of DDGS in the diet exceeds 20%, 0.015% of crystalline L-glutamic acid must be added for every 10% DGS in the diet. DDGS can also replace corn and soy hulls in the diet for pregnant animals.
