Metabolizable energy and amino acid digestibility of corn distillers dried grains with solubles with or without enzymes supplementation in broiler diets

Effects of dietary digestible amino acids and a novel exogenous sfericase protease on growth performance of broilers

“…The magnitude of response to a given protease can be variable considering the digestibility of the undigested nutrient fraction. It has been widely reported that protein and AA digestibility are variable according to ingredients, quality of protein in feedstuffs from vegetable origin and diet composition as well as the substrate composition, birds’ age, and nutritional AA levels [ 2 , 3 , 6 , 16 ]. The digestibility of CP and AA in poultry feeds has indicated that valuable amounts of protein pass through the gastrointestinal tract without being completely digested [ 17 ], which has been the main opportunity to exogenous proteases.…”

Possibilities of dried distillers' grains with solubles application in animal feed

“…On the other hand, some characteristics such as the content of crude fiber, mostly the insoluble fraction, the lack of some amino acids such as lysine, the high fluctuations in gross energy and oil O N L I N E F I R S T content, as well as the proportion and quality of crude protein of maize DDGS represent obstacles to the addition of a higher percentage of DDGS in diets for some groups of animals (Rochell et al, 2011;Meloche et al,2013). Some authors reported that the processing parameters during bioethanol and DDGS production (temperature, the type of process, duration of separate phases of the process) can decrease the bioavailability and the digestibility of crude protein and amino acids, mainly lysine (Dalólio et al, 2020).…”
