Abstract This study was conducted to determine the standardized ileal digestibility (SID) of amino acids (AA) in hydrolyzed feather meal (HFM), flash dried poultry protein (FDPP), poultry meal (PM), and meat and bone meal (MBM) fed to broiler chickens and pigs. Four semi-purified diets and a nitrogen-free diet were prepared. Exp. 1 was conducted with 416 male broiler chickens (initial body weight [BW] = 705 ± 100.0 g) at d 18 post-hatching in a randomized complete block design. Birds were fed diets for 5 d and then euthanized to collect ileal digesta. In Exp. 2, ten barrows (initial BW = 22.1 ± 1.59 kg) surgically fitted with T-cannulas at the distal ileum were assigned to duplicate 5 × 4 incomplete Latin square design with 5 diets and 4 periods. There were 5-d adaptation and 2-d ileal digesta collection periods in each experimental period. Data were analyzed as a 2 × 4 factorial arrangement with the effects of species (i.e., broiler chickens and pigs) and four experimental diets. There were interactions (P < 0.05) in the SID of His, Lys, Thr, Trp, and Val between diets and species. In broiler chickens, the SID of Lys in MBM was greater (P < 0.05) than HFM and FDPP but was not different from PM. Pigs fed MBM had greater (P < 0.05) SID of Lys than HFM, FDPP, and PM. In broiler chickens, the SID of His, Thr, and Trp in FDPP and PM were greater (P < 0.05) than HFM but was less (P < 0.05) than MBM. In pigs, the SID of His, Thr, and Trp in FDPP and PM were greater (P < 0.05) than HFM but was not different from MBM. In conclusion, differences in the SID of AA among animal protein sources were affected by species of monogastric animals.

Abstract The objective of this study was to compare the standardized ileal digestibility (SID) of amino acids (AA) in 3 poultry by-products including hydrolyzed feather meal (HFM), flash dried poultry protein (FDPP), and poultry meal (PM) and also a meat and bone meal (MBM) between broiler chickens and pigs. Experimental diets consisted of 4 diets containing each test ingredient as a sole source of nitrogen and a nitrogen-free diet. In experiment 1, 416 male broiler chickens with a mean initial body weight (BW) of 705 ± 100 g were allotted to 5 diets with 8 replicate cages per diet in a randomized complete block design with BW as a blocking factor at day 18 posthatching. After 5 d of feeding experimental diets, birds were euthanized by CO2 asphyxiation, and ileal digesta samples were collected from distal two-thirds of the ileum. In experiment 2, 10 barrows with a mean initial BW of 22.1 ± 1.59 kg were surgically fitted with T-cannulas at the distal ileum and allotted to a duplicate 5 × 4 incomplete Latin Square design with 5 diets and 4 periods. Each period lasted for 7 d including 5 d of adaptation and 2 d of ileal digesta collection. Data from experiments 1 and 2 were pooled together and analyzed as a 2 × 4 factorial arrangement with the effects of species (broiler chickens or pigs) and 4 experimental diets (HFM, FDPP, PM, or MBM). There were interactions (P &lt; 0.05) between experimental diets and species in the SID of His, Lys, Thr, Trp, Val, and all dispensable AA except Tyr. In broiler chickens, the SID of Lys in FDPP (73.3%) was greater (P &lt; 0.05) than in HFM (55.7%) but was lower (P &lt; 0.05) than in MBM (86.5%), which was not different from PM (78.7%). In pigs, however, the SID of Lys in FDPP and PM (70.0 and 70.1%, respectively) were greater (P &lt; 0.05) than in HFM (39.0%) but were lower (P &lt; 0.05) than in MBM (79.2%). Broiler chickens fed FDPP and PM had lower (P &lt; 0.05) SID of His, Thr, and Trp than those fed MBM; however, there was no difference in the SID of His, Thr, or Trp among pigs fed FDPP, PM, or MBM. The SID of Val in MBM was greater (P &lt; 0.05) than in the other test ingredients for broiler chickens, but there was no difference in the SID of Val among test ingredients for pigs. Pigs had greater (P &lt; 0.05) SID of Ile and Met than broiler chickens. In conclusion, the pattern of differences in the SID of His, Lys, Thr, Trp, and Val, but not the other indispensable AA, among poultry by-products and MBM were different between broiler chickens and pigs.

Apparent Metabolizable Energy

Enzymes benefit digestion and absorption of the ingredients and their addition to an animal-origin meal (AOM) can improve its nutritional quality. This research aimed to evaluate the effect of protease on nutrient digestibility, amino acids, and metabolism of AOM energy for broilers. Four hundred and eighty broiler chickens were distributed in a completely randomized design (4 × 2 factorial scheme), eight treatments, six replicates containing 10 birds/replicate. Treatments consisted of poultry viscera meal, swine viscera meal (SVM), bovine meat and bone meal, and basal diet; with and without protease addition. Two tests were performed. In the first test, the total excreta collection method was used with birds at 13 to 20 days of age and 25% of the reference feed was replaced by AOM. In the second test, a protein-free diet was administered to birds at 21 to 24 days of age and AOM replaced 25% of the starch. The inclusion of protease increased the apparent metabolizable energy corrected for nitrogen balance of SVM by 15.99% and the apparent metabolizable crude energy by 5.7%, and it also raised the coefficient of true ileal digestibility of the amino acids in the AOMs by 5.67% on average. The inclusion of protease improved the apparent metabolizable crude energy of AOMs, apparent metabolizable dry matter of bovine meat and bone meal, coefficient of true ileal digestibility of essential amino acids, and apparent metabolizable energy corrected for nitrogen balance of SVM. Dietary supplementation of protease may be a potential strategy to improve the digestibility of amino acids for broilers, a possibility of using animal-origin meals as a protein source of diets.

Abstract The objective of this study was to compare the standardized ileal digestibility (SID) of AA in fish meal (FM), porcine plasma (PP), porcine red blood cell (RBC), and blood meal (BM) between broiler chickens and pigs. Five diets were prepared for both species including 4 diets containing test ingredients and a nitrogen-free diet. In Exp. 1, 416 male broiler chickens (initial BW = 705 ± 100.0 g) at d 18 post hatching were assigned to diets in a randomized complete block design with BW as a blocking factor. After 5 d of feeding, birds were euthanized for collection of ileal digesta. In Exp. 2, 10 barrows (initial BW = 22.1 ± 1.54 kg) surgically fitted with T-cannulas at the distal ileum were allotted to duplicate 5 × 4 incomplete Latin square design with 5 diets and 4 periods. Each experimental period consisted of 5-d adaptation and 2-d ileal digesta collection periods. Data for Exp. 1 and 2 were considered together as a 2 × 4 factorial arrangement with the effects of species (i.e., broiler chickens and pigs) and four diets (i.e., FM, PP, RBC, and BM). There were interactions (P &lt; 0.05) between species and diets on the SID of AA except for Pro. The SID of Lys, Met, Thr, and Trp in FM, PP, and RBC for broiler chickens were not different from values for pigs; however, the SID of respective AA in BM for broiler chickens were less than values for pigs. The SID of indispensable AA in BM were less than in FM, PP, or RBC within each species, but the SID of indispensable AA in BM for broiler chickens was less than values for pigs. In conclusion, utilization of AA in animal protein ingredients containing high concentration of CP varies between broiler chickens and pigs.

Abstract AbstractThree experiments were conducted to test the hypothesis that standardized ileal digestibility (SID) of amino acids (AA), concentration of metabolizable (ME), and standardized total tract digestibility (STTD) of P in a new source of distillers dried grains with solubles (DDGS; ProCap DDGS) are greater than in conventional de-oiled DDGS. In experiment 1, nine barrows (initial BW: 67.2 ± 6.4 kg) with a T-cannula in the distal ileum were allotted to a triplicated 3 × 3 Latin square design with three diets and three periods for a total of nine replicate pigs per diet. Two diets included ProCap DDGS or de-oiled DDGS as the sole source of crude protein (CP) and AA. An N-free diet was used to determine the basal endogenous losses of CP and AA. Ileal digesta were collected on days 5 and 6 of each period after 4 d of adaptation to diets. Results from experiment 1 indicated that ProCap DDGS contained more CP and AA compared with de-oiled DDGS. The SID of all AA in ProCap DDGS was greater (P &lt; 0.001) compared with de-oiled DDGS with the exception that the SID of Pro was not different between the two sources of DDGS. In experiment 2, 24 growing barrows (initial BW: 32.7 ± 3.1 kg) were housed individually in metabolism crates and used in a randomized complete block design and fed a corn-based diet or two diets containing corn and each source of DDGS with eight replicate pigs per diet. Fecal and urine samples were collected for 4 d after 7 d of adaptation. Results from experiment 2 indicated that concentration of ME in ProCap DDGS was greater (P &lt; 0.05) compared with corn or de-oiled DDGS. In experiment 3, 32 growing barrows (initial BW: 20.2 ± 0.9 kg) were placed in metabolism crates and allotted to four diets with eight pigs per diet using a 2 × 2 factorial treatment arrangement. The de-oiled DDGS and ProCap DDGS were both included in a diet without microbial phytase and a diet with microbial phytase (500 units/kg diet). Pigs were adapted to the diets for 5 d and fecal samples were collected for 4 d. Results from experiment 3 indicated that inclusion of phytase in the diet containing ProCap DDGS increased (P &lt; 0.05) the STTD of P, but addition of phytase to the de-oiled DDGS diet did not increase STTD of P (interaction, P &lt; 0.001), but the STTD of P was greater (P &lt; 0.05) in de-oiled DDGS compared with ProCap DDGS. In conclusion, ProCap DDGS has greater SID of AA and contains more ME, but has reduced STTD of P compared with conventional de-oiled DDGS.

Abstract Two experiments were conducted to evaluate the digestible energy (DE), metabolizable energy (ME), and standardized ileal digestibility (SID) of amino acids (AA) in dried yeast (DY) and soybean meal (SBM) fed to pigs. In Exp. 1, 30 barrows with an initial body weight (BW) of 20.7 ± 1.01 were assigned to 5 diets in a randomized complete block design with period and BW as blocking factors. A basal diet was prepared to contain corn, canola meal, and soybean oil as energy-contributing ingredients. Four additional diets were prepared by adding 5 or 10 g/kg DY or SBM at the expense of energy-contributing ingredients in the basal diet to estimate the DE and ME in test ingredients by regression analysis. On a dry matter basis, estimated DE and ME in DY were 4,022 and 3,352 kcal/kg, respectively, and those in SBM were 3,876 and 3,601kcal/kg, respectively. There was no difference in estimated DE or ME between DY and SBM. In Exp. 2, 21 barrows (initial BW = 20.0 ± 1.31 kg) surgically fitted with T-cannulas at the distal ileum were assigned to 3 diets in a randomized complete block design with BW as a blocking factor. Two diets were prepared to contain DY or SBM as the sole source of nitrogen, and a nitrogen-free diet was prepared to determine the basal ileal endogenous losses of AA. The SID of AA, except for Gly and Pro, in SBM were greater (P &lt; 0.05) than in DY. The SID of indispensable AA in DY ranged from 64.7% for Thr to 86.1% for Arg, whereas those in SBM ranged from 84.8% for Thr to 92.3% for Arg. In conclusion, energy values in DY was comparable with SBM, but the SID of most AA in DY were less than in SBM.

Abstract An experiment was conducted to investigate the effect of rice bran (RB) and Ronozyme® WX on apparent and true ileal amino acid (AA) digestibility coefficients in broiler chicks using a regression approach. Two hundred and forty 21-day-old Abor Acre plus chicks were randomly allotted to six diets with varying levels of RB (100, 200 and 300 g/kg) without (0g/kg) or with Ronozyme® WX (25g/kg) supplementation in a 2x3 factorial arrangement using a randomized complete block design. Each treatment had 5 replicates with 8 birds each. The birds were fed for 5 days (d 22–26). On d 26, digesta was sampled from distal ileum. Data were analyzed using general linear model at α0.05. Lysine had the highest concentration among the essential amino acids (AAs) while the lowest concentration was observed for threonine. Rice bran at 10% for the essential amino acids with enzyme was significantly higher but compared with concentrations of RB at 10% and 20% without enzyme. There were no significant differences among the true ileal amino acid digestibility coefficients except lysine (10% RB) without enzyme (0.91) which was significantly higher than 20% RB with enzyme (0.84) but similar to other treatments. Rice bran with enzyme had a significant (P &lt; 0.05) interactive effect on the apparent ileal digestibility coefficients of arginine, histidine, isoleucine methionine and phenylalanine. When RB was supplemented with enzyme, a significant (P &lt; 0.05) interactive effect on true ileal digestibility coefficients of arginine and methionine was observed. Rice bran-enzyme interaction had no significant effect on the non-essential AAs. The slopes of the regression lines ranged from 0.77 (arginine) to 0.98 (phenylalanine). In conclusion, enzyme supplementation did not significantly influence the digestibility coefficients of AA in rice bran. However, the inclusion of 10% and 20% RB supplemented with Ronozyme® can help to improve the methionine content in rice bran.

Dietary Protein Level

The effect of dietary protein content (25, 60, 95, 130, 165 and 200 g crude protein (N × 6.25)/kg diet) on the apparent and true ileal digestibilities of N and amino acids in meat-and-bone meal given to the growing rat was investigated. Semi-synthetic diets in which meat-and-bone meal was the sole protein source were given to 180 g body-weight rats for 14 d. On the fourteenth day the rats were fed and then killed 4 h after the start of feeding and digesta were sampled from the terminal 200 mm ileum. Endogenous amino acid excretion was determined for eighteen rats given an enzymically hydrolysed casein (EHC)-based diet and with subsequent treatment of the digesta using ultrafiltration. The EHC-fed rats were killed 3 h after the start of feeding and digesta were collected from the terminal 200 mm ileum. True ileal digestibility values determined with reference to Cr as a marker were higher than the corresponding apparent estimates. Apparent digestibility values of N and amino acids increased significantly (P < 0.001) with increasing dietary protein level; however, dietary protein content had no significant (P > 0.05) effect on the true ileal digestibilities of N and amino acids. The mean apparent ileal digestibility of N in meat-and-bone meal ranged from 65.6 to 75.3%. The corresponding range for the true ileal digestibility of N was 76.9 to 78.2%. True ileal digestibility, unlike apparent digestibility, appears to be independent of dietary protein level and may allow feed ingredients to be compared accurately even if they are ingested in different quantities.
