“…At present, we are not aware of any reports describing the nutritional value of triticale DDGS for poultry or recommended inclusion levels in practical diets. Antinutritional factors, in particular nonstarch polysaccharides (NSP), are likely to limit nutrient digestibility and maximum inclusion levels of triticale DDGS in broiler diets as they do in the intact grain (Antoniou and Marquardt, 1981;Al-Athari and Guenter, 1988). The antinutritional effects of NSP in triticale DDGS could be overcome through supplementation with exogenous NSP-degrading enzymes, which successfully increased nutrient digestibility in triticale grain for broilers (Pourreza et al, 2007).…”

The nutritive value of triticale distillers dried grains with solubles (DDGS) for broilers was investigated in 2 experiments. In experiment 1, four hundred male broilers housed in battery cages were fed diets including 15 or 30% triticale DDGS (extruded or not) or a basal diet, supplemented with or without a multi-enzyme complex from d 21 to 28. Birds were killed and ileal digesta was collected on d 28 to establish the apparent ileal nutrient digestibility (AID) coefficients for both assay diets and DDGS as test ingredients based on 5 cages per diet. In experiment 2, a 42-d performance study compared growth phase-specific diets formulated to similar levels of AME, CP, and digestible lysine with graded levels (0, 5, or 10%) of triticale DDGS inclusion based on a minimum of 4 pens per diet x sex combination. Breast muscle weight and percentage yield were determined on d 37 by sampling 5 birds per pen. In experiment 1, there was a significant (P < 0.05) DDGS level of inclusion x enzyme interaction for CP, lysine, methionine, tryptophan, isoleucine, histidine, and phenylalanine, such that the AID increased with enzyme supplementation based on 15% but not 30% DDGS inclusion. At 15% DDGS inclusion, enzyme supplementation increased the AID of these nutrients in DDGS between 6 and 19 percentage units. Extrusion of triticale DDGS increased (P < 0.05) the AID of GE, CP, methionine, tryptophan, branched-chain amino acids, and phenylalanine between 3 and 8 percentage units. In experiment 2, feeding up to 10% triticale DDGS had no adverse effect on feed intake, weight gain, or feed efficiency of broilers compared with controls over the 42-d study. Feeding up to 10% triticale DDGS did not affect breast weight or yield on d 37. In conclusion, feed enzyme complex supplementation and extrusion both increased the nutritive value of triticale DDGS for broilers. Triticale DDGS can be fed at up to 10% of practical broiler diets without adverse effect on performance and breast muscle yield.

“…Earlier studies have indicated that a mild acid-autoclave treatment was partially successful in alleviating the growth-depressing properties of rye for chicks (MacAuliffe et al 1976), although autoclaving alone was ineffective (Moran et al 1969;Antoniou and Marquardt 1981 (Pettersson and Aman 1988) ). Pettersson and Aman (1989) …”

“…As growing (O'Neil and Rae, 1965;, ergot toxicity was dismissed as an explanation for the growth depression observed with Sample B. The adverse effect of rye on the growth of chicks has been attributed to the properties of pentosans in rye grain (Antoniou and Marquardt, 1981). The possibility of toxic levels of pentosans arising from the rye parentage of triticale should be explored as a possible source of antinutritional activity.…”

True metabolizable energy (TME) values and amino acid compositions of three triticale and two wheat samples were determined. The TME values of triticale and wheat averaged 3.54 kcal (14.8 kj) and 3.60 kcal (15.1 kj)/g dry matter, respectively. Triticale protein contained more lysine, arginine, aspartic acid, and alanine than wheat protein. One of two triticale samples linearly depressed live weights at 38 days when fed in diets for Small White turkeys at 0, 150, 300, and 450 g/kg as a direct substitute for wheat. Ergot contamination was eliminated as a possible cause of the growth depression observed. The possibility of adverse levels of pentosans in triticale was considered. (
