Nutritional value of distillers dried grains with solubles from corn and sorghum and xylanase in diets for pigs

Abstract

Two experiments were conducted to evaluate the digestibility and energy of distillers dried grains with solubles (DDGS) from corn and sorghum with or without xylanase enzyme in diets for pigs. The values of dry matter (DM), organic matter (OM), crude protein (CP), mineral matter (MM), ether extract (EE), neutral detergent fiber (NDF), gross (GE), digestible (DE), metabolizable energy (ME), and digestibility coefficients (DC) were determined. In the experiment 1, we used eight barrows of 26.15±3.45 kg with repeated measures in three periods of five days of collection. The treatments consisted of a reference diet (RD); RD with 200 g kg −1 corn DDGS or sorghum DDGS; and RD with 400 g kg −1 corn DDGS or sorghum DDGS. Corn DDGS showed higher values of DE, ME, and DC of EE, GE, and CP. Inclusions of 400 g kg −1 of the test ingredients resulted in higher values of DE and ME and trend for higher DC of DM, OM, and CP. In experiment 2, nine barrows weighing 34.91±1.46 kg were fed RD, 200 g kg −1 corn DDGS or 200 g kg −1 corn DDGS plus xylanase enzyme. The inclusion of xylanase did not influence the digestibility and energy values in diets containing corn DDGS. Values of DE and ME of corn DDGS were 3,477 and 3,277 kcal kg −1 , respectively, for the substitution of 200 g kg −1 and 3,761 and 3,068 kcal kg −1 for the substitution of 400 g kg −1 RD. For sorghum DDGS, DE and ME values were 3,030 and 2,863 kcal kg −1 , respectively, for replacement of 200 g kg −1 and 3,398 and 3,296 kcal kg −1 for substitution of 400 g kg −1 RD. Levels of up to 400 g kg −1 do not influence the DE and ME of the diets but impair the digestibility coefficient of DM, OM, CP, EE, MM, and NDF. The use of xylanase enzyme in diets containing 200 g kg −1 of corn DDGS does not affect the digestibility of the diets.

Variabilidade da composição nutricional de coprodutos de etanol de milho do Brasil para suínos

“…Por outro lado, Stuani et al (2016), em uma abordagem analítica, compilaram resultados de diversos estudos e obtiveram um valor médio de 3.695 kcal/kg para EM. Outro estudo investigando DDGS de milho produzido no Brasil, Corassa et al (2019) registraram valores de 3477 e 3761 kcal/kg para ED e 3277 e 3609 kcal/kg para EM com 20 e 40% de inclusão do ingrediente na dieta, respectivamente.…”

“…Com enorme potencial de substituição aos ingredientes tradicionais, os coprodutos de etanol de milho podem reduzir custos e otimizar formulações de rações para cadeias produtivas como a suinocultura brasileira, a quinta maior do mundo (ABPA, 2019) entretanto, pouquíssimos estudos com coprodutos do Brasil foram realizados (Corassa et al, 2017(Corassa et al, , 2019(Corassa et al, , 2021.…”

Dried distillers grains with solubles in diets during late gestation affects behavior and maintains the performance of sows

“…The inclusion of 300 g kg −1 DDGS in the diet of gestating sows tends to elicit an early display of lying or inactivity behavior. Therefore, the fiber provided through DDGS favors welfare to gestating sows, despite the worsening in the digestibility coefficient of the diet compared with corn-soybean meal diets (Corassa et al, 2019). Furthermore, according to De Leeuw et al (2005), sows fed highfiber diets, exhibit less frequent posture changes during gestation, which reduces aggressiveness Dried distillers grains with solubles in diets during late gestation affects behavior and maintains the... Corassa et al and occurrence of other stressing factors during this period, which is especially important for housed group like in this study.…”

Comparison of chemical composition, energy content, and digestibility of different sources of distillers corn oil and soybean oil for pigs

“…Ethanol production from corn generates co-products such as dried distillers grains (DDG), DDG with solubles (DDGS), and high protein DDG (HPDDG), which contain great content of lipids, crude protein, and energy, being widely used in non-ruminant feeding in North America (Stein and Shurson, 2009;Chatzifragkou and Charalampopoulos, 2018). Few studies about these corn co-products produced in Brazil over their nutritional value and the effects on pigs and poultry growth performance and carcass traits have been performed in the last few years (Corassa et al, 2017;Schone et al, 2017;Bittencourt et al, 2019;Corassa et al, 2019;Paula et al, 2021).…”
