A total of 360-d-old male Ross 308 broilers were raised until 20 days of age with a standard commercial starter diet (metabolizable energy, 3000 kcal/kg, crude protein, 22%, Ca 0.9%, P 0.6%). On 21 days of age all birds were weighed and assigned to 5 experimental treatment groups with 6 replicate cages each consisted of 12 birds. Each P source was included at two levels (to achieve increments of 0.075% and 0.15%) to the basal diet. Titanium dioxide was included at 0.5% in all diets as indigestible marker. On day 28, all birds were sacrificed and ileal digesta were collected. The prececal P digestibility of DCP and MCP were calculated by the linear regression to be 76.60% and 85.83%, respectively. The present results suggest that the P digestibility of the P sources should be considered when formu...

In the study, seventy-five 25 weeks-old commercial white laying hens were randomly divided into one control and 4 treatment groups each containing 15 hens. Control group was fed basal diet without JA or V. Treatment group 1, 2, 3 and 4 were fed diets containing 5% V, 5% JA, 5% JA + 5% V and 10% JA + 10% V, respectively. The feeding period lasted 16 weeks. In the study, it was determined that dried-ground JA contained dry matter, crude protein, ether extract, crude fibre, crude ash, inulin and metabolizable energy (ME) at the level of 93.30, 10.02, 0.36, 5.64, 9.05, 15.80% and 3 060 kcal/kg, respectively. At the end of the study, live weight was lower by 4.36–10.09% in the treatment group 10% JA + 10% V compared with the other groups, but feed efficiency was improved in this group. T...

Control and treatment groups were fed a diet containing 0, 5 and 10% Jerusalem artichoke, respectively. Twenty five weeks old, 45 commercial white laying hens were used in the experiment. In this experiment, inulin was effective on modifying of intestinal characteristics, blood metabolites and liver enzymes in laying hens. Fecal and intestinal pH values were not altered by dietary treatments. Although, unchanged serum cholesterol and albumen content, 5% JA increased glucose (p<0.001) and decreased fructose (p<0.01), triglyceride (p<0.01) and total protein (p<0.05) contents when compared with control diet. On the other hand, 10% JA reduced serum glucose as well as fructose levels. Serum SGOT levels was increased (p<0.01) by 5% JA addition and ALP levels was decreased (p<0.05) by 10% JA.

In this study, Merino rams with ruminal fistulas were used (n = 4) to determine the effect of glucose treatment of soybean meal (SBM), full fat soybean (FFSB) and soybean seed (SBS) on the ruminal degradability of dry matter (DM) and crude protein (CP). All these feedstuffs were grinded, diluted with water and heated (2 h; 100 degrees C) either without or with supplementation of 2 or 3% glucose (20 or 30 g glucose per kg dry feed). For the determination of the ruminal degradability nylon bag technique was used (incubation times: 2-48 h). In general ruminal degradability of protein in all three soy products was reduced by glucose treatment. In FFSB CP disappearance ...

The study was conducted to determine the effects of xylose treatment of soybean meal (SBM), full fat soybean (FFSB) and soybean seed (SBS) on rumen degradability of dry matter (DM) and crude protein (CP) in four ruminally cannulated two years old Merino rams. These feedstuffs were treated with water + heat, water + heat + 2% xylose or 3% xylose. Xylose treatments at both levels (2% and 3%) decreased (p<0.001) effective degradability values (Pe) of DM and CP in SBM. Although the calculated reduction coefficients for effective CP degradability values of SBM treated with 2% and 3% xylose (37% vs 41%) were similar, they were different compared to that of untreated SBM. The calculated reduction coefficients for effective CP degradability values of FFSB and SBS treated with 2% and 3% xylose were 15.6% and 25%; 25.8% and 28.3, respectively. In conclusion, xylose treatment is more effective on protection of SBM proteins from rumen degradation compared to FFSB and SBS proteins wh...

A total of 320 one-day-old male broiler chicks were randomly allocated to 4 treatments (8 floor pens, 10 birds/pen) including 1) negative control (NC) birds fed a basal diet and not challenged with E. coli K88; 2) positive control (PC) birds fed a basal diet and challenged with of E. coli K88; 3) P. xylanexedens ysm1 treatment (PRO) birds fed a basal diet supplemented with 1 × 10 9 P. xylanexedens ysm1 cfu/kg feed and challenged with E. coli K88; and 4) antibiotic treatment (ANT) birds fed a basal diet supplemented with 20 mg of colistin sulphate/kg of feed and challenged with E. coli K88. The E. coli challenge decreased (P < 0.05) BWG in PC birds compared with the ANT birds on days 21 and 28. The FCR was higher (P < 0.01) in PC birds compared with the NC, PRO, and ANT birds on days 14, 21, and 28. Compared with the NC, PRO, and ANT birds on day 28, PC birds had shorter villi and higher number of goblet cells in both jejunum and ileum (P < 0.001). Irrespective of the dietary treatments, the E. coli challenge reduced the number of PCNApositive cells in both the jejunum and ileum on day 28. Paenibacillus xylanexedens ysm1 treatment resulted in higher concentration of mucosal sIgA in the jejunum as compared to the other treatment groups on days 14 and 28. The numbers of cecal E. coli were reduced (P = 0.017) in broilers treated with P. xylanexedens ysm1 or antibiotic in comparison with the PC group on day 28. In conclusion, the present study demonstrated that dietary supplementation of this new probiotic bacteria P. xylanexedens ysm1 improved broiler performance by modulating intestinal morphology, enhancing immune response, and reducing the number of E. coli in the cecum.

The DM of meals was determined by drying at 105°C for 24 h, and sufficient water or mixtures of water and xylose (0.5 and 1%) were added to increase the moisture content of SBM and CSM to 25% (McAllister et al., 1993). These meals were thoroughly mixed with each solution and heated for 2 h at 100°C in a convection air oven. Trial 1 Three ruminally cannulated Merino rams aged 1.5 years weighing approximately 60 kg were fed twice daily (at 09.00 h and at 16.00 h) with a ration containing 200 g concentrate (barley, 51%; sunflower meal, 25%; wheat bran, 21%; salt, 1%; dicalcium phosphate, 1% and vitamin+ mineral premix, 1%) and 1.000 g alfalfa hay. Nylon bag technique was used to measure disappearance of DM, OM and CP in the rumen of untreated and treated SBM and CSM. Nylon bags (45 µm pore size; 9×14 cm bag size)

A total of 680 three-day old Japanese quail chicks (Coturnix coturnix japonica) were assigned to 20 battery brooders, 34 chicks in each. The experimental period lasted 35 days. The treatment groups employed were: 1) a positive control which included 3.5 g available phosphorus (AP)/kg diet and 10 g Ca/kg diet; 2) a negative control which included 2 g AP/kg diet and 8 g Ca/kg diet, 3) negative control diet supplemented with either 300 FTU phytase/kg diet (phytase) or 4) 2.5 g organic acid (lactic acid+formic acid)/kg diet (organic acid); or 5) 300 FTU phytase/kg diet+2.5 g organic acid/kg diet (phytase+organic acid). All birds were fed with the positive control diet for a week and then transferred to the dietary treatments. At the end of the study, there were no differences (p>0.005) among the groups in body weight, weight gain, feed consumption, feed conversion ratio and carcass yield. Tibia ash, however, was reduced (p<0.001) for quails fed the negative control diet containing a lowlevel of AP compared to the positive control diet containing adequate AP. The addition of phytase, organic acid or phytase+organic acid to the diets containing the low-level of AP improved (p<0.001) tibia ash. On the other hand, an extra synergistic effect of phytase and organic acid on tibia ash was not determined. This study demonstrated that it may be possible to reduce supplemental level of inorganic P with phytase and/or organic acid supplementation for quail diets without adverse effect on performance and tibia ash.

In the experiment, three ruminally cannulated mature Merino rams were used to measure in situ rumen degradability characteristics of dry matter (DM), organic matter (OM) and crude protein (CP) of meal samples. CM and SBM were treated with xylose (5, 10 and 20 g/kg DM). Xylose treatment reduced maximum potential degradability values of DM, OM, CP for SBM but not for CM. Rumen effective protein degradability values of CM and SBM (k = 0.02, 0.05 and 0.08 h −1) were decreased by all treatments. Effective degradabilities of DM, OM, CP (k = 0.05 h −1) were 0.643, 0.628 and 0.772 for untreated canola meal (UCM) and 0.622, 0.608 and 0.546 for untreated soybean meal (USBM), respectively. Effective crude protein degradability values (k = 0.05 h −1) of CM treated with xylose (5, 10, and 20 g/kg DM) were 0.73, 0.67 and 0.60, respectively. Treatment of SBM with 5, 10 and 20 g/kg of DM caused a reduction in the effective crude protein degradability at the rate of 37, 48 and 65% compared with USBM, respectively. It was concluded that CM and SBM proteins can be effectively protected from degradation in the rumen by xylose treatment.

Dietary treatments consisted of a 2×2×4×4 factorial arrangements with two levels of supplemental phytase (0 or 1200 FTU kg), two levels of 25-OH (0 or 69 µg kg), four levels of Ca-1-1 (0.20% less than a 2:1 ratio of Ca to NPP; 2:1 ratio of Ca to NPP; 0.20% Ca greater than a 2:1 ratio of Ca to NPP; 0.40% Ca greater than a 2:1 ratio of Ca to NPP) and four levels of NPP (0.35, 0.40, 0.45 and 0.50%) for a total of 64 treatments. The primary basal diet was supplemented with a complete vitamin mix containing 5500 IU of cholecalciferol. Each diet was fed to six replicates per treatment; each pen having 6 birds. At 18 d birds were weighed, feed consumption determined and all birds killed for bone measurements. Toes from all birds within a pen were removed and ashed. Tibiae from both legs were removed and scored for incidence and severity of tibial dyschondroplasia and for incidence of Ca or P rickets. Ca: NPP ratios and Ca levels similar or higher than NRC (1994) recommendations appear necessary for adequate bird performance. Phy supplementation improved FCR, whereas the addition of 25-OH to diets already containing 5500 IU kg of cholecalciferol had a negative effect on FCR due to a possible hypercalcemia condition. Bone-1 development was improved by increasing NPP and Ca levels. Moreover, supplementation with 25-OH was effective in reducing leg abnormalities. Addition of 25-OH helped to relieve leg problems when suboptimal Ca levels were supplied while Phy supplementation was effective for this purpose when high Ca levels were given. These additives could be seen as a strategy to alleviate problems with suboptimal Ca: NPP ratios.

In the first experiment, glycerine was added at 0, 5, and 10% of the diet while in the second experiment glycerine was added at 0, 2.5, and 5%. Glycerine was assigned a metabolizable energy value of 3527 ME kcal/kg in formulating the diets. In each experiment the various treatments were assigned to eight replicate pens of 60 male broilers each. In the first experiment, birds fed diets with 5% glycerine did not differ significantly in performance from birds fed the control diet with no glycerine. Birds fed diets with 10% glycerine consumed significantly less feed than did those fed diets with 0 or 5% glycerine and consequently had significantly reduced body weight. It is felt that this was due in large part to reduced flow rate in the feeders used in this study as previous researchers have shown acceptance of higher levels of glycerine. In the second study, birds fed diets with 2.5 or 5% glycerine had growth rate and feed conversion that did not differ significantly from that of birds fed the diet with no glycerine. Breast yield as a percent of the dressed carcass was significantly greater for birds fed diets with 2.5 or 5% glycerine as compared to those fed the diet with no glycerine. These data indicate that glycerine from biodiesel can be a useful energy source for use in broiler diets. Concerns remain regarding acceptable levels of residual methanol resulting from separation of the fatty acids in biodiesel production.
