“…The experimental design was a 5 × 3 incomplete Latin square design consisting of five treatments and three periods, two dogs per treatment in each period, and thus six replicate dogs per treatment (Ai et al, 2013;Jeong et al, 2015). The periods lasted 15 days, with five days for adaptation to the cage and experimental diet, followed by five days of total feces and urine collection to determine digestibility, according to the recommendations of AAFCO (2008).…”

-This study was conducted to determine the coefficient of total tract apparent digestibility (CTTAD) of nutrients and gross energy (GE), metabolizable energy (ME), coefficient of metabolizability of gross energy (CM of GE), and fecal characteristics of dogs fed diets with two levels of feather meal, with or without addition of an enzyme blend containing lipase and protease activity. Ten adult Beagle dogs (aged between 1 and 2 years and weighing 10.2±1.4 kg) were arranged in a 5 × 3 incomplete Latin square design with five treatments and three periods. The extruded basal diet was provided in equal amounts to all dogs (220 g/d), and 7.5 and 15% of hydrolyzed feather meal without enzymes (HFM) or HFM processed with addition of the enzyme blend (HFM EB) was added on top of the basal diet just before feeding. The contrast analysis showed that inclusion of 7.5 or 15% feather meal negatively affected CTTAD of crude protein (CP), GE, and ME of the diets with no apparent effect of the enzyme treatment. However, when both feather meal samples were evaluated, the HFM EB resulted in better CTTAD of GE and CM of GE (0.774 vs. 0.666) than HFM without enzymes (0.670 vs. 0.567), respectively. There was no effect of either feather meal on fecal score. Regression analysis showed that the enzymes added to the feathers during the digestion process increased digestible energy by 600 kcal/kg of dry matter in the diet containing HFM EB. High-performance liquid chromatography (HPLC) analysis demonstrated that feather meal had a low molecular weight, with about 95% of the molecules below 10,000 Da. Addition of enzymes during the feather hydrolysis process may improve the energy content of the feather meal when included in diets for adult dogs.

“…Individual feed ingredient as well as mixed diets show different digestibilities for protein and dry matter (Jeong et al, 2015) according to origin of ingredients (Sarwar, 1987;Pellett, 1996) or nutrient composition of diets including crude protein, crude fiber, and dry matter (Otto et al, 2003). Due to the increasing price of feed ingredients, mainly due to an increasing demand for biofuel production, use of co-products such as distillers dried grains (DDG) has increased for new feedstocks.…”

This study was conducted to investigate the digestibility of dry matter (DM) and nitrogen (N) in oilseed meals and distillers dried grains (DDG) fed to growing-finishing pigs. As experimental animals, eleven barrows (initial body weight, 71.7 ± 17.0 kg) were housed in individual metabolism cages. The experimental design consisted of an 11 × 8 incomplete Latin square with 11 dietary treatments and 8 replication periods. The diets were individually formulated with dehulled soybean meal produced in Korea (SBM-KD), soybean meal produced in India (SBM-I), soybean meal produced in Korea (SBM-K), corn high-protein distiller dried grains (HPDDG), tapioca distillers dried grains (TDDG), canola meal (CAM), corn germ meal (CGM), copra meal (COM), palm kernel meal (PKM), sesame meal (SM), and perilla meal (PM). Pigs with SBM-KD and SBM-K showed greater (p < 0.05) intake of N than SBM-I, HPDDG, and PKM. Total feces output was decreased (p < 0.05) in SBMs (SBM-KD, -I, and -K), HPDDG, and CGM compared with TDDG, SM, and PM. The DM in excreted feces was decreased (p < 0.05) in SBMs and CGM compared to TDDG, SM, and PM. Similarly, the SM and PM fed to pigs resulted in greater (p < 0.05) fecal excretion of N than the others. Apparent total tract digestibility (ATTD) of DM in SBMs and CGM was greater (p < 0.05) than TDDG, SM, and PM. The SBMs fed to pigs showed higher (p < 0.05) ATTD of N than TDDG, COM, SM, and PM. In conclusion, our results provided nutritional information about various ingredients and would be useful to contain more precise amounts of nutrients included in feed ingredients of pig diet.

“…In particular, the CTTSD of P, which is correlated with the BEL of P, has recently been adapted to the nutrient requirements of swine (NRC, 2012). Although studies have determined CTTSD of P in major feed ingredients (Almeida & Stein, 2010;Rojas et al, 2013;Almaguer et al, 2014;Jeong et al, 2015), information about minor ingredients is limited. The authors hypothesized that various feed ingredients affect the digestibility of P. Therefore, the purpose of the current study was to evaluate the CTTSD of P in eleven alternative feedstuffs, including nine oilseed meals and two DDG in growing-finishing pigs.…”

This study was conducted to determine the coefficient of total tract standardized digestibility (CTTSD) of phosphorus (P) in oilseed meals and distillers dried grains (DDG) fed to growing-finishing pigs. Twelve barrows (initial bodyweight (BW) ± standard deviation, 52.25 ± 2.57 kg) were allocated individually to metabolism cages. The experimental design was a 12 × 8 incomplete Latin square with 12 dietary treatments and eight replication periods. The diets were formulated individually with dehulled soybean meal produced in Korea (SBM-KD), soybean meal produced in India (SBM-I), soybean meal produced in Korea (SBM-K), corn high-protein distiller dried grains (HPDDGs), tapioca distillers dried grains (TDDG), canola meal (CAM), corn germ meal (CGM), copra meal (CM), palm kernel meal (PKM), sesame meal (SM), perilla meal (PM), and a P-free diet. Intake of P was highest in SM and PM. Excretion of P was reduced in y ascending order as HPDDG, TDDG and CGM; SBM-K; and SM and PM. The CTTAD of P was higher in CGM than SBM-K, TDDG, SM and PM. HPDDG and CGM showed greater CTTSD of P than SBM-K, CAM and PM. Digestible concentration of P on CTTSD (CTTSD-P) of P was greater in PM and CAM than the others except for SBM-KD. In summary, PM could be utilized as an alternative feedstuff to SBM, but its usage is regarded only as a source of P. In addition, the results of the current study would provide valuable information for formulating pig feed with precise P utilization in ingredients using mixed diets. ______________________________________________________________________________________
