DDGS and enzymes make a good mix in broiler diets.

Distillers Dried Grain with Solubles (DDGS) is the result of extracting ethanol from grains through dry milling. The average level of protein contained in the DDGS is 26% (as fed). The level of total Lysine is higher than in corns with low digestibility (60-70%). In the case of sulphur amino acids, the digestibility is a little bit higher (70-75%). If we take a finisher standard diet for broilers (28-42 days for birds) based on corn and soy with a 15% inclusion of DDGS as an example, the level of protein in the diet is nearly 20%, with digestible lysine that represents 5% of the total and moderated levels of sulphur amino acids and threonine digestible (12% and 13% respectively). The content of unsaturated fat is high (5-10%). The hydrolysis process and the drying to which the product is submitted increases the concentration of free fatty acids. Between different authors, the ME can vary between 2,600 and 2,950 Kcal, depending fundamentally on the composition, processes and digestibility coefficients from different fractions. The content of total phosphorus is high, with high availability, resulting in 0.45-0.55% of avail-able phosphorus. They can also contain high levels of xanthophyll, which can improve pigmentation; up to 35 mg/kg were found in DDGS. The levels of crude fibre obtained analytically are in excess of 10%. Almost all the starch has been converted to ethanol, so that a big concentration of non-starch polysaccharides and especially cell-wall components exists. This is why the use of exogenous enzymes is presented as an alternative; to increase the efficient use of nutrients in diets formulated with DDGS. DDGS can be a good alternative ingredient in diets for broilers. Its use in combination with a multi-enzymatic complex, combined with an extra dose of phytase, can help to achieve optimal performance. A few trials, conducted in Argentina, are described here; In the first assay, 640 male broilers were distributed between 32 floor pens according to a randomised, complete block design. With 20 birds per pen, it consisted of four treatments with diets containing 15% of DDGS: A-diet with a normal energy level; B-diet with a low level of energy (-150Kcal) and a 50g dose of multi-enzymatic complex (xylanase, amylase and protease); C-diet with a low level of energy (-150Kcal) and a 100g dose of multi-enzymatic complex (xylanase, amylase and protease); D-diet with a normal energy level and 100g dose of a bacterial phytase (dose equal to 1,000 FTU). The feeding plan consisted of a pre-starter for up to 10 days, a starter from 11 to 21 days, and a finisher up to 42 days. Although statistical differences were not found with the statistical methods used, numerically speaking, the diets formulated with DDGS with a low level of energy and the addition of multi-enzymatic complex resulted in higher body weight (Table 1) and less feed conversion than DDGS diets with normal levels of energy without the addition of enzymes. The DDGS used contained 10% crude fibre. The addition of multi-enzymatic complex increased the digestibility of diets with a greater fibre content. The addition of 1,000 FTU of phytase (750 FTU formulated and 250 FT on top) to DDGS diets with normal levels of energy resulted in better weight and less feed conversion than the rest of the treatments. The addition of an extra dose of phytase would allow benefits to be gained from other nutrients, not only phosphorus. read more about research ;http://www.allaboutfeed.net/Nutrition/Raw-Materials/2015/12/DDGS-and-enzymes-make-a-good-mix-in-broiler-diets-2721468W/
