“…Starch was almost completely digested at the end of the small intestine in the present experiment, in accordance with the results found in pigs of different age fed with various dietary starch sources 10–12. Weaned pigs fed barley diets had total NSP AID in the range of 18–32% 11, 27.…”

“…Non‐starch polysaccharide sugars (arabinoxylans, β‐glucan) may negatively affect the nutritive value of cereals as shown particularly in young chickens 32–34. In pigs, although there is evidence to support the practice of supplementation with NSP‐degrading enzymes, the results are not conclusive 12. However, β‐glucans in the diet are known to elevate the viscosity in digesta,35, 36 lowering the utilisation of dietary nutrients 37…”

“…Describing the protein value of foods in terms of their ileal digestible amino acids, although laborious and still not optimal, is useful to estimate the actual amounts which become available to the organism 9. While a number of studies have appeared in the literature concerning intestinal digestibility of wheat or barley starch and NSP in pigs,10–12 the information on this topic is very limited for triticale and totally absent in the case of the Iberian pig. Accordingly, the aim of the present work was to explore barley and triticale digestibilities of amino acids and carbohydrates in growing Iberian pigs.…”

BACKGROUND: Iberian pig production is linked to the use of the Mediterranean woodland, where the use of local feed resources is of paramount importance for the sustainability of the system. The aim of the present work was to explore the potential of triticale cv. Camarma as compared to barley cv. Esgueva in Iberian pig feeding by studying their respective ileal digestibilities of amino acids and carbohydrates in animals cannulated at the end of the ileum.

“…Crystalline among varieties of corn exist as has been demonstrated for barley (van Wijk et al, 1998;McCann et al, 2006) and for field peas (Fan and Sauer, 1999). Because of the increased concentration of standardized ileal digestible indispensable AA in NutriDense corn compared with yellow dent corn, less supplemental protein such as soybean meal is needed in diets containing NutriDense Table 11.…”

Two experiments were conducted to measure the energy and nutrient digestibilities in NutriDense corn and other cereal grains. An additional objective was to evaluate the effect of balancing diets with AA on the values measured for DE and ME of corn varieties. In Exp. 1, 6 growing pigs were fitted with a T-cannula in the distal ileum and allotted to a 6 x 6 Latin square design to measure apparent ileal digestibility (AID) and standardized ileal digestibility (SID) values for CP and AA in NutriDense corn, yellow dent corn, barley, wheat, and sorghum. Diets based on each of the 5 cereal grains were formulated, along with a N-free diet. Results of this experiment showed that the AID for most indispensable AA were greater (P < 0.05) in NutriDense corn and wheat than in the other cereal grains. The SID for Lys in NutriDense corn (77.6%) was greater (P < 0.05) than in yellow dent corn (68.5%), and sorghum (56.9%), but not different from wheat (75.1%) and barley (71.7%). The SID for Arg and Met in NutriDense corn also were greater (P < 0.05) than in yellow dent corn (88.1 and 87.2% vs. 84.5 and 82.8%, respectively). For the remaining indispensable AA, no differences in SID between NutriDense corn and yellow dent corn were observed. For all AA, the lowest values (P < 0.05) for AID and SID were obtained for sorghum. If calculated as grams of standardized ileal digestible AA per kilogram of DM, concentrations of all indispensable AA in NutriDense corn were greater (P < 0.05) than in yellow dent corn, but barley and wheat had greater concentrations of most AA than yellow dent corn and NutriDense corn. In Exp. 2, 12 growing barrows were placed in metabolism cages, and the DE and ME of NutriDense corn and yellow dent corn were measured. Both grains were used in diets without or with crystalline AA supplementation. Each diet was fed to 6 pigs in a 2-period, changeover design. The DE and the ME in NutriDense corn (4,004 and 3,922 kcal/kg of DM, respectively) were greater (P < 0.01) than in yellow dent corn (3,878 and 3,799 kcal/kg of DM, respectively). Values for DE and ME were not affected by the addition of crystalline AA to the diets. It is concluded that NutriDense corn has a greater value than yellow dent corn in diet formulations due to increased concentrations of digestible, indispensable AA and energy. However, barley and wheat have greater concentrations, whereas sorghum has lower concentrations, of many digestible AA than NutriDense corn.

“…So, there is an interaction with the exogenous and endogenous enzymes secreted by animals (Bedford & Schulze ; McCann et al . ). We hypothesize that the hydrolysis process in vitro can save energy rather than the direct addition of exogenous energy to animals.…”

Two experiments were conducted to assess the feeding value of water-soaked barley (WB) as a replacement for dehulled barley (DB) in pigs. In experiment (Exp.) 1, eight barrows (body weight = 30.56 ± 0.78 kg) were fitted with a T-cannula and allotted to a duplicated 4 × 4 Latin square design: WB10, 100g/kg WB; WB20, 200 g/kg WB; DB10, 100 g/kg DB; and DB20, 200 g/kg DB. In Exp. 2, 80 barrows (body weight = 70.56 ± 1.29 kg) were used in a 56-day experiment: (i) WB15, 150 g/kg WB; (ii) WBD10, 100 g/kg WB and 50 g/kg DB; (iii) WBD5, 50 g/kg WB and 100 g/kg DB; and (iv) DB15, 150 g/kg DB. In Exp. 1, the apparent ileal digestibilities of total essential amino acids were higher (P < 0.05) in WB10 treatment than DB20. For Exp.2, the WB15 and WBD10 had higher pH and lower cooking loss (P < 0.05) than other two treatments. The WB15 treatment decreased (P < 0.05) the contents of palmitic acid (C16:0) in Longissimus dorsi muscle than WBD5 and DB15 treatments. In conclusion, it is suggested that water-soaked barley improved some amino acid digestibility and the cooking loss and moderate fatty acid profiles in Longissimus dorsi muscle.
