“…The SID of CP and AA in corn gluten meal used in the present study were within a range of data in the literature [27,28]. While corn gluten feed and corn gluten meal were the co-products from corn, the SID values were variable between the sources, which may be explained by different concentrations of corn fractions [29]. The SID of CP and AA in lupin hulls was similar to that in SBM.…”

Objective: The objective was to determine standardized ileal digestibility (SID) of crude protein (CP) and amino acids (AA) in cereal grains and various co-products fed to growing pigs.Methods: Ten feed ingredients tested were barley (9.3% CP), lupin kernels (31.1% CP), and wheat (11.3% CP) as cereal grains, and 2 sources of corn gluten feed produced in China (21.6% CP) and Korea (24.6% CP), corn gluten meal (65.3% CP), lupin hulls (11.6% CP), rice bran (14.5% CP), soybean meal (44.8% CP), and wheat bran (15.4% CP) as co-products. Ten experimental diets were formulated to contain each ingredient as a sole source of N and an N-free diet was used to correct basal endogenous losses of CP and AA. All diets also contained 0.5% Cr2O3 as an indigestible index. A replicated 11×6 incomplete Latin square design with 11 dietary treatments, 6 periods, and 22 animals was employed. Twenty-two barrows with an initial body weight of 64.6±4.9 kg were equipped with a T-cannula in the distal ileum. An experimental period consisted of a 4-d adaptation period and a 2-d collection period.Results: The SID of CP in the barley, lupin kernels, wheat, 2 sources of corn gluten feed, corn gluten meal, lupin hulls, rice bran, soybean meal, and wheat bran were 84.7%, 90.5%, 90.4%, 77.4%, 74.6%, 89.5%, 90.4%, 74.4%, 86.9%, and 63.4% (standard error of the mean [SEM] = 5.3, p = 0.006), respectively. The respective SID values of Lys were 75.5%, 88.4%, 83.9%, 74.7%, 62.4%, 80.3%, 83.9%, 78.5%, 88.0%, and 71.2% (SEM = 3.3, p<0.001), and the SID values of Met were 83.6%, 88.7%, 89.4%, 85.7%, 78.3%, 88.9%, 89.4%, 85.3%, 91.1%, and 77.0% (SEM = 2.4, p<0.001), respectively.Conclusion: The ileal digestibility of protein and amino acids varies among the feed ingredients fed to pigs.

“…Most of the cereal byproducts are higher in nutritional value than the original grains in terms of protein, fat, and fiber content. Corn gluten feed (CGF), wheat gluten (WG), and corn germ meal (CGM) have been widely used in the ruminant diets as protein supplements that provide not only adequate nutrition but also riboflavin, vitamin A, and vitamin E to ruminants [4].…”

“…The reference concentration values for total α-carotene, total lycopene, and total lutein plus zeaxanthin are from the medians of the laboratory means from the interlaboratory comparison exercise (Levenson, et al, 2000). Another study reported that yellow corn contains relatively high carotenoid content, ranging from 11 to 20 μg/g (Loy et al, 1987). Carotenoids such as lutein and zeaxanthin content in white corn are not affected by drying and milling (Mamatha et al, 2012).…”

In the present study, bitter dry beans of lupine seeds (Lupinus termis L.) cultivar Giza-1, and powder of turmeric rhizomes, (Curcuma longa L.,), and grains of yellow corn (Zea mays L.) cultivar Giza-368 were used to prepare three tercumin capsules. Chemical composition and elementary analysis of all capsules and their sources were done. The tercumin capsules composed from three portions, the first one, is fine powdered lupine seeds (FPLS), the second portion is turmeric powdered (TP) and the third one is the grain husks of yellow corn (GHYC). Generally, these data ` that the three chosen crops studied here are good, complementary and inexpensive sources for composed capsules. While the crude protein (6.69-34.15 %) and lipids (3.82-11.07%) and TSS (21.16-25.32%). From obtained, results turmeric rhizomes contain the highest content of lutein, zeaxanthin, β-cryptoxanthin and β-carotene followed by bitter lupines Giza-1, and husks of yellow corn grain. Lupine seeds, turmeric rhizomes and yellow corn grains contain large quantities of carotenoid pigments, which can be used as dietary supplements or as safe food additives. Results of carotenoid levels in three tercumin capsules show that lutein, zeaxanthin, β-cryptoxanthin and β-carotene content in tercumin capsule-2 are higher than those determined in tercumin capsule-3 and tercumin capsule-1. TPCs in both tercumin capsules and their sources tercumin capsules ranged from 2.18 to 29.48 mg/100g. TPCs in the yellow corn grains are higher than those found in the bitter lupine seeds Giza-1 (2.185 mg/100g) and turmeric rhizomes. TPCs concentrations in the tercumin capsules-3 are higher than those found in the tercumin capsules-1 and tercumin capsules-2. The levels of TPCs in the tercumin capsules-1, capsules-2 and capsules-3 are 20.1, 25.63 and 29.480 mg/100g respectively. Total flavonoid contents in tercumin capsules and their sources were assayed and the results indicate that turmeric powdered contained the highest level 4.97 mg/100 g CE followed by grain husks of yellow corn (GHYC) and the lowest level (1.396) was found in the powder of lupine seed Giza-1.The results also showed that tercumin capsule-3 contain the highest concentration (5.142) of TFs followed by tercumin capsule-1and tercumin capsule-2 contain the lowest concentration. These results showed that total alkaloids in turmeric rhizomes (1.82%) are higher than those determined in yellow corn grains (1.203%). The levels of TAs in turmeric rhizomes are always higher than those determined in yellow corn grains.
