Abstract
AbstractThe present study was carried out to evaluate the effect of dietary supplemental vitamin D3(VD3) on P absorption and utilisation as well as its related mechanisms in the small intestine of broilers. A total of 384 1-d-old Arbor Acres male broilers were assigned randomly into four treatments following a completely randomised design with a 2 (dietary non-phytate P (NPP) contents: 0·43 and 0·22 %)×2 (dietary VD3supplemental levels: 0 and 87·5 μg/kg) factorial arrangement. The experiment lasted for 22 d. The results showed that P contents in serum from the hepatic portal vein and tibia ash of broilers were higher (P<0·05) for 0·43 % NPP than for 0·22 % NPP. The type IIb Na-dependent phosphate cotransporter (NaP-IIb) protein expressions in the duodenum and ileum were higher (P<0·05) also for 0·43 % NPP than 0·22 % NPP. Supplementation of VD3enhanced (P<0·05) tibia P retention rate and type III Na-dependent phosphate cotransporter (PiT)-1 protein expression in the duodenum of all broilers. Moreover, VD3supplementation decreased (P<0·002) mortality and increased (P<0·02) serum P content from the hepatic portal vein after 4 h of feeding, tibia ash content, tibia ash P content and protein expressions of NaP-IIb and PiT-1 in the jejunum of broilers fed diet with 0·22 % NPP. Thus, dietary supplemental VD3promoted intestinal P absorption and bone P utilisation, and this effect might be associated with enhanced PiT-1 levels in the duodenum and PiT-1 and NaP-IIb levels in the jejunum respectively when dietary NPP is limiting.

Abstract
The objective of the current study was to examine the effect of the inclusion levels of distiller's dried grains with solubles (DDGS) which partially and fully replaced soybean meal (SBM) in laying hen diets with or without enzyme or vitamin E supplementation on nutrients digestibility and excreted nitrogen and phosphorous. For these purposes, a total of 180 Hisex Brown laying hens at 22 weeks of age were randomly distributed into 15 treatment groups in a 5 × 3 factorial design experiment including five levels of DDGS (0, 5.5, 11, 16.5 and 22% replaced for the same percent of SBM which represents 0, 25, 50, 75 and 100% respectively in the diet) and three levels of feed additives (without, 250 mg enzyme/kg diet or 200 mg vitamin E/kg diet) through 22-42 weeks of age. Results revealed that digestion coefficient values of nutrients including DM, OM, CP, EE, NFE and CF were more preferable in hens fed diets involved 25% DDGS instead of SBM than that of the control diet and other treatment groups. In contrast, hens fed 100% substitution of DDGS caused significant (P ≤ 0.01) decrease in digestibility coefficients of all nutrients. The amount of daily excreted N was decreased in hens fed 25 or 50% DDGS substitution, whilst feeding 75 or 100% DDGS led to an elevation in N excretion. The proportion of excreted phosphorous was statistically (P ≤ 0.01) decreased as the level of DDGS increased. Generally, neither enzyme nor vitamin E supplementation had any significant effect on the studied parameters. It could be concluded that DDGS could be used up to 50% as a replacement of SBM (11% of the diet) without any adverse effects on nutrients digestibility. Laying hen farms using DDGS up to 25 or 50% substituted for SBM in its diets (5.5 or 11% of the diet) will have clearer environment of nitrogen and phosphorous pollution than others whose diets free of DDGS.

Abstract
It is becoming a common practice to use higher levels of wheat distillers dried grains with solubles (wDDGS) in poultry diets. The objective of this study was to determine the effects of level of inclusion of wDDGS with or without enzyme (E-, i.e., wDDGSE-) supplementation on performance and water consumption of turkey hens (0 to 72 d). Two diets (0 or 30% wDDGS) were formulated to meet the nutrient requirements of Hybrid Converter turkeys. Diets (0 or 30% wDDGS; starter, grower, and finisher) were then blended to obtain a different level of inclusion (15%) of wDDGS. The 30% wDDGS diet was divided into 3 fractions and 2 fractions supplemented with either protease (P+, i.e., wDDGSP+; 0.126 g/kg) or β-mannanase (M+, i.e., wDDGSM+; 0.05 g/kg). All 5 diets were fed ad libitum as mash. The 700 0-d turkey hens were randomly allocated into groups of 35 birds per replicate with 4 replicate floor pens per treatment, in a completely randomized design. Water consumption per pen was recorded beginning at 7 d. There was no effect of dietary treatment on feed intake. BW of turkey hens (52 d; grower) was significantly higher for 30% wDDGSP+ as compared to 0% wDDGSE- or 15% wDDGSE- diets; but was not different from 30% wDDGSE- or 30% wDDGSM+ diets. FCR (P < 0.01; 28 to 52 d), and total FCR (P < 0.05; 0 to 72 d) was significantly improved for birds fed 15 or 30% wDDGS regardless of enzyme treatment compared to 0% wDDGSE-. Water intake (WI, in mL per bird per day) tended to be higher (P = 0.08) between 7 and 28 d for 30% wDDGSP+ diets compared to other treatments. Similarly, WI of birds fed 30% wDDGSP+ was higher (P < 0.05; 28 to 52 and 52 to 72 d) and total WI (P = 0.07; 7 to 72 d) tended to be higher than other treatments. This study is the first to report the impact of wDDGS on WI. As high as 30% wDDGS can be substituted in turkey hen diets. No effect of P+ or M+ at the inclusion level tested was found on performance.

Hydrolysis of phytate and formation of inositol phosphate isomers without or with supplemented phytases in different segments of the digestive tract of broilers. J Nutr Sci 2015; 4:e1.

Abstract
The objective was to characterise degradation of myo-inositol
1,2,3,4,5,6-hexakis (dihydrogen phosphate) (InsP6) and formation of inositol
phosphate (InsP) isomers in different segments of the broiler digestive tract. Influence
of an Aspergillus niger (PhyA) and two Escherichia
coli-derived (PhyE1 and PhyE2) phytases was also investigated. A total of 600
16-d-old broilers were allocated to forty floor pens (ten pens per treatment). Low-P
(5·2 g/kg DM) maize–soyabean meal-based diets were fed without (basal diet; BD) or with a
phytase added. On day 25, digesta from different digestive tract segments were pooled per
segment on a pen-basis, freeze-dried and analysed for P, InsP isomers and the marker
TiO2. InsP6 degradation until the lower ileum (74 %) in BD-fed
birds showed a high potential of broilers and their gut microbiota to hydrolyse
InsP6 in low-P diets. Different InsP patterns in different gut segments
suggested the involvement of phosphatases of different origin. Supplemented phytases
increased InsP6 hydrolysis in the crop (P < 0·01) but
not in the lower ileum. Measurements in the crop and proventriculus/gizzard confirmed
published in vitro degradation pathways of 3- and 6-phytases for the
first time. In the intestinal segments, specifically formed InsP4–5 isomers of
supplemented phytases were still present, indicating further activity of these enzymes.
Myo-inositol tetrakisphosphate (InsP4) accumulation differed
between PhyE1 and PhyE2 compared with PhyA in the anterior segments of the gut
(P < 0·01). Thus, the hydrolytic cleavage of the first phosphate
group is not the only limiting step in phytate degradation in broilers.

Abstract
Two studies were conducted to determine the true P digestibility (TPD) of black-eyed pea (BEP) and peanut flour (PNF) and the TPD response to phytase supplementation using the regression method. Sequential diets containing 115, 230, or 345 g of BEP/kg (experiment 1) and 115, 230, or 345 g of PNF/kg (experiment 2) without or with 1,000 units of phytase/kg were formulated. Chromic oxide was added to the diets at the rate of 5 g/kg as an indigestible marker. At 20 d posthatch in each study, 384 male broiler chickens (Ross 708) were weighed and allotted to the diets with 8 replicates of 8 birds each in a randomized complete block design. The birds had free access to the experimental diets until d 26 posthatch. In both studies, dietary P increase and phytase supplementation improved (P < 0.001) growth performance of the broiler chickens. There were linear increases (P < 0. 001) in ileal and excreta P output but a linear decrease (P < 0.001) in apparent P digestibility with an increase in dietary P levels. Phytase supplementation reduced (P < 0.001) ileal P and excreta P output and increased (P < 0.001) apparent P digestibility and retention. Apparent Ca digestibility was affected (P < 0.01) by P level and phytase addition in BEP and by P level (P < 0.05) in PNF. Apparent Ca retention in BEP increased (P < 0.05) with phytase addition. The TPD in the BEP increased (P < 0.01) from 29 without phytase to 83% with the addition of 1,000 units of phytase/kg. There was an increase (P < 0.01) in TPD of PNF from 67 without phytase to 75% with phytase supplementation. There was a corresponding increase (P < 0.01) in true P retention from 10% without phytase to 61% with phytase in birds on BEP diets and an equivalent increase (P < 0.01) in true P retention from 74% without phytase to 84% with phytase in birds that received the PNF diets.

Abstract
An experiment was conducted to evaluate the influence of a novel microbial phytase on broiler performance from d 0 to 42 and tibia ash at d 21. Male Cobb 500 broilers (n = 2,016) were fed 1 of 7 experimental diets: positive control (PC) formulated to meet or exceed nutrient recommendations; PC plus dicalcium phosphate (PC+DCP) formulated to provide Ca and P at 0.10% above the PC; PC plus 500 U/kg of microbial phytase (PC+500); negative control (NC) with Ca and P reduced from the PC by 0.16 and 0.15%, respectively; and NC plus 500 (NC+500), 1,000 (NC+1,000), or 1,500 (NC+1,500) U/kg of microbial phytase. Diets were fed in 3 phases from d 0 to 21, d 22 to 42, and d 43 to 49 to 32 birds/pen and 9 replicate pens/diet. From d 0 to 21, broilers fed the NC diet had decreased (P ≤ 0.05) BW gain and tibia ash compared with broilers fed all other diets, except tibia ash in birds fed PC+500. Phytase supplementation at 500, 1,000, or 1,500 U/kg to the NC improved (P ≤ 0.05) BW gain and tibia ash comparable with the PC. Feed conversion ratio (FCR) was improved (P ≤ 0.05) in broilers fed NC+1,500 compared with broilers fed all other diets. From d 0 to 49, growth performance was not influenced (P > 0.05) by diet. However, FCR was improved (P ≤ 0.05) in broilers fed 1,500 U/kg of microbial phytase compared with broilers fed the PC, PC+DCP, and NC. There were no differences in performance or tibia ash between broilers fed the PC or PC+DCP, which would indicate the PC diet was sufficient in Ca and P. Therefore, the improvements in FCR in the NC+1500 may be associated with mitigation of the antinutrient effects of phytate rather than improved P utilization.

Abstract
BACKGROUND An experiment was conducted to investigate the effect of sorghum distillers' dried grains with solubles (sDDGS) and xylanase supplementation in broiler chicken diets. A total of 432 Cobb-500 day-old male broiler chicks were used in a 4 × 2 factorial design (0, 100, 200 or 300 g kg(-1) sDDGS with or without xylanase supplementation). Each treatment was replicated six times with nine birds per replicate in a 35 day study. RESULTS Feed intake was increased (P < 0.001) throughout the study with the inclusion of dietary sDDGS. Body weight gain (BWG) was unaffected except for the last 2 weeks of study, when birds that received 200 and 300 g kg(-1) sDDGS had higher (P < 0.001) BWG. Feed conversion ratio (FCR) increased (P < 0.05) as sDDGS in the diet rose to 100 g kg(-1) during the starter phase and the whole period of study. Over the starter period, xylanase supplementation improved (P < 0.05) FCR, particularly for the highest inclusion of sDDGS. Protein digestibility deteriorated (P < 0.001) as sDDGS in the diet rose to 300 g kg(-1) . Xylanase reduced (P < 0.001) the concentration of xylose in the ileum of birds. The activities of sucrase and maltase in the jejunal mucosa were reduced when birds were offered 200 and 300 g kg(-1) sDDGS. Incorporation of sDDGS increased (P < 0.01) the total short-chain fatty acid concentration in the caeca. CONCLUSION The results showed that diets containing large amounts of sDDGS will benefit from xylanase supplementation, particularly in terms of FCR.

Abstract
Two experiments were conducted to estimate standardized phosphorus (P) retention (SPR) of corn, soybean meal (SBM), and corn-soybean meal (C-SBM) diet in broilers and verify the additivity of SPR for feed formulation of broilers. In total, ninety-six 22-d-old male broilers with similar BW were used in each experiment. After 3 d of acclimation, chicks were fasted for 24 h and then fed P-free, corn, SBM, or C-SBM diets, respectively for 4 h in experiment 1 or 72 h in experiment 2. In experiment 1, the results showed that the excreta collection time of 52 h (48 h after feed withdrawal) was adequate for the estimation of SPR. The basal endogenous P loss (EPL) of chicks fed the P-free diet was estimated to be 123±7 mg/52 h per bird. The values of SPR corrected by basal EPL were 37.6 and 50.5% for corn and SBM, respectively. The determined value of SPR of the C-SBM diet was very close (P>0.79) to the predicted summation of SPR from corn and SBM (44.4 vs. 43.5%). In experiment 2, the results showed that the excreta collection time of 96 h (24 h after feed withdrawal) was sufficient for the estimation of SPR. The basal EPL of chicks fed the P-free diet was estimated to be 85.4±4.0 mg/96 h per bird. The values of SPR corrected by basal EPL were 40.2 and 52.9% for corn and SBM, respectively. The determined value of SPR of the C-SBM diet was lower (P<0.001) than the predicted summation of SPR from corn and SBM (39.7 vs. 46.0%), which might be due to the effect of higher total P intake. The results from the current study demonstrated that the P-free diet could be used for measuring basal EPL in broilers and then estimating the SPR values of feedstuffs for broilers. However, the additivity of SPR in the diet formulation needs to be studied further.

Abstract
Three experiments were conducted to evaluate the compositional and nutritional values of corn grains [phytase transgenic corn (PTC) and isogenic conventional corn (CC)] and compare the efficacy of corn-based phytase and extraneous microbial phytase for enhancing the utilization of phytate phosphorus (P) in single corn or corn-soybean mixed meals (corn:soybean = 2.5:1, wt:wt) fed to roosters. Following a 48-h fasting period, 16 roosters were given 50 g of each sample via crop intubation and excreta were collected for 48 h. Nitrogen-free and phosphorus-free diets were used to evaluate endogenous amino acid and endogenous P losses, respectively. Chemical composition was not different between PTC and CC, whereas the phytase content for PTC was greater than CC (8,047 vs. 37 FTU/kg of corn, DM basis; P < 0.001). No difference was observed in the TME and true amino acid availability values between the PTC and CC in roosters. The true P utilization for PTC was greater than CC (37.92 vs. 55.85%; P < 0.001), and CC and PTC contained 0.13 and 0.19% available P (AP, DM basis; P < 0.001), respectively. There was no difference in P utilization (72.76 vs. 70.23%; P > 0.05) between roosters fed PTC and extraneous microbial phytase in equivalent FTU/kg of diets. The results of this study indicated that the chemical composition, TME, and true amino acid availability in PTC are essentially equivalent to that in CC, and the true P utilization for roosters is higher in PTC than in CC. Corn expressing phytase is as efficacious as equivalent microbial phytase when supplemented in corn-soybean diets for chickens.

Abstract
1. This experiment investigated growth performance and nutrient utilisation responses of broilers to partial replacement of maize and soyabean meal in broiler diets with 100 g kg(-1) maize Distillers' Dried Grain with Solubles (mDDGS) as well as responses to supplementation of an admixture of carbohydrases and protease (XAP) or phytase individually or in combination in the diets. 2. A total of 288 one-day-old broilers were allocated to 8 treatments in a randomised complete block design and a 2 x 2 x 2 factorial arrangement of treatments. The three factors were two levels each of mDDGS (0 or 100 g kg(-1)), phytase (0 or 1000 FTU kg(-1)), and XAP (0 or 500 mg kg(-1)). 3. Each treatment had 6 replicate cages with 6 birds per replicate cage. The control diets were formulated to meet all nutrient requirements of broilers according to National Research Council recommendations of 1994, but were marginally deficient in non-phytate P and ME. 4. Weight gain and gain:food were higher in broilers receiving diets containing mDDGS. The coefficient of apparent ileal N digestibility was lower in diets with mDDGS. Phytase increased the coefficient of apparent ileal DM digestibility in all diets. 5. Phytase improved the coefficient of the apparent total tract DM retention independently of mDDGS and tended to improve the coefficient of apparent P retention in the diets without mDDGS. The enzymes were additive in their effects in the diets with mDDGS. Overall, the results showed that adding 100 g kg(-1) mDDGS to a maize-soyabean meal diet had no negative effect on growth when energy and nutrient concentrations were similar to the maize-soyabean meal diet, and that phytase or an admixture of carbohydrases and protease individually or in combination modestly improved nutrient utilisation independently of mDDGS addition. Combination of the enzymes did not produce greater benefit than the use of phytase alone.
