The value of tail-end partially dehulled canola meal (DCM) was assessed in comparison to the conventional canola meal (CCM) from which it was derived using broiler chickens. CCM obtained from five crushing plants underwent the partial-dehulling. Nutrient retention was determined using 33-d-old broiler chickens and a 21 -d growth study was also conducted. DCMs contained a higher concentration of crude protein and amino acids and the utilization of energy and amino acids was improved. Energy utilization was also affected by crushing plant and there was an interaction between plant and meal type, suggesting that the dehulling was not uniform for meals obtained from the five plants. The DCM had higher digestibilities than the CCM (for 10 amino acids), but there were also plant effects for 7 amino acids. In the second experiment, feed intake, weight gain and mortality levels were not affected by tail end dehulling, but feed efficiency was. The similarity in chick performance and health between the chicks fed DCM and CCM indicates that there was no apparent concentration of anti-nutritional factors. In conclusion, although variability between crushing plants is a concern, tail-end dehulling has potential to increase the quality and marketability of canola meal for poultry diets.

Standardized ileal digestibility (SID) of amino acids (AA) and apparent metabolizable energy corrected for nitrogen (AMEn) in samples of organic corn and soybean meal (SBM) were determined. Conventional corn (CC) and SBM (CSBM) samples were tested for comparison. A total of 560, fourteen-day-old male broiler chickens (Cobb 500) were weighed, placed in cages (10 birds per cage), and allocated to seven (n = 8) semi-purified wheat-starch-based diets. Diets were (1) CC, (2) imported organic corn, (3) local organic corn, (4) CSBM, (5) imported organic SBM (OSBMI), (6) local organic SBM (OSBML), and (7) nitrogen-free wheat starch. Only few differences were observed on SID of AA; SID of lysine was lower (P = 0.002) in organic corn samples relative to CC, and SID of methionine was lower (P = 0.002) in OSBML sample relative to CSBM and OSBMI samples. The AMEn of CC was higher (P < 0.01) than that of organic corn samples. The AMEn of OSBML was higher (P < 0.001) than for CSBM and OSBMI; however, the value for OSBMI was higher (P < 0.001) than for CSBM. In conclusion, utilization of AA in conventional and organic feedstuffs was comparable; however, differences in energy utilization warrant considerations in organic broiler feed formulation.

The effects of replacing between 0 and 100% of dietary soybean meal with canola meal was investigated using broiler chicks and laying hens. At the highest inclusion levels, canola meal accounted for 38 and 25% of the diet of broilers and layers, respectively. For broiler chicks, there was no effect of the dietary treatments on feed intake, weight gain or feed efficiency (P > 0.05). Canola meal replaced 100% of dietary soybean meal without any significant effect on protein, fat, calcium, phosphorus or magnesium retention and energy utilization. There was also no significant effect of replacing soybean meal with canola meal on fecal soap concentration, bone ash and bone calcium, phosphorus and magnesium content. There was no significant effect of replacing all dietary soybean meal with canola meal on performance, nutrient retention and bone mineralization in laying hens (P > 0.05). These results suggest that canola meal can replace soybean meal without any adverse effects on general performance, nutrient retention or mineral metabolism of chicks and laying hens.

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 The objective of this work was to evaluate the effect of the use of hybrid phytase, alone or combined with carbohydrases, in poultry diets with nutritional reductions of calcium, available phosphorus, and metabolizable energy on the nutrient digestibility and bone quality of broiler chickens. A total of 1,875 broilers were distributed in five treatments in a completely randomized design, with 15 replicates of 25 chickens each. The treatments consisted of a positive control feed (T1) and of four negative controls (T2 to T5): T1, basal diet (BD) with corn and soybean; T2 and T3, BDs with reductions of 70 and 100 kcal kg-1 metabolizable energy, respectively, and both with reductions of 0.16% Ca and 0.15% available P; and T4 and T5, BDs with the same nutritional reductions, but supplemented with enzymes, i.e., T4 = T2 + 500 phytase units (FTU) per kilogram and T5 = T3 + 500 FTU kg-1 + 560 xylanase units (TXU) per kilogram + 250 glucanase units (TGU) per kilogram. The use of 500 FTU kg-1 hybrid phytase in pelleted corn-soybean meal diets allows a good digestive performance by broilers and replaces the nitrogen-corrected apparent metabolizable energy at 70 kcal kg-1, as well as 0.16% Ca and 0.15% available P.

Abstract BackgroundThe use of newly harvested corn in feed causes wet droppings in broilers and increased feed cost which was termed as “new season grain problem”. The present study was conducted to evaluate the proteomic profile of newly harvested corn and the subsequent influence on intestinal microbiol community for broiler chickens. MethodsNewly harvested corn stored for either half a month (HM) or two months (TM) was used, and the pasting properties, total soluble sugars, and proteomic analysis technology was used to explore the influence of storage on natural aging corn properties. Additionally, seventy-two 7d Ross 308 male broiler chicken were fed with different stored corn. Apparent metabolizable energy (AME), digesta viscosity, intestinal morphology and microbiota were examined to explore the influence of feed corn storage on broiler chickens. ResultsPasting properties in the TM corn exhibited decreased viscoelastic properties. Proteomic studies found a total of 26 proteins that were differentially expressed between the two treatment groups. Proteins involved in starch and polysaccharides biosynthesis were upregulated in TM compared with HM. Chickens fed on TM diet had higher relative energy utilization compared to the HM birds. With increased corn storage, the relative digesta viscosity decreased significantly (P≤0.05). The total number of goblet cells and lymphocytes was lower in chickens fed the TM diet. The microbiota data showed that the TM chickens had decreased abundance of diarrheal bacteria such as Hungatella hathewayi and Bacteroides fragilis, and increased butyrate-producing bacteria such as Alistipes compared to the HM chickens. ConclusionsStorage of newly harvested corn induced the synthetic reaction of large molecules and changed the solubility of starch and protein with increasing soluble sugars and decreasing pasting properties that may improve the fermentation of intestinal microbiota, improve the energy utilization and protect gut health without the risk of diarrhea.

Abstract The aim of investigations was the estimation of nutritional value of currently cultivated yellow lupine cultivars in raw and extruded form, and their usefulness for broiler chickens. Two experiments were conducted with male Ross 308 chickens. In a digestibility trial 60 fifteen-day-old birds were randomly assigned to three dietary treatments (20 replications in each). Birds were kept in individual pens. Digestibility was calculated using the difference method. From day 16 to 21, diets contained lupine meal in raw or extruded form and the basal diet in the ratio 20:80. Subsequently, the total digestibility of dry matter and crude fat, also apparent nitrogen retention and AMEN value of lupine seeds were determined on chickens fed different forms of lupine. The ileal digestibility of crude protein and amino acids of lupine seeds was also analyzed. In the second experiment the one-day-old birds were randomly assigned to ten dietary treatments (10 replications in each) and were fed diets with increasing amounts of raw or extruded lupine from 10 to 30%. The chickens in control treatments were fed a diet without lupine. Extruded yellow lupine meal was characterized by lower phytic P content in comparison to raw yellow lupine meal. The content of remaining ingredients and antinutritional substances was similar. Yellow lupine seeds post extrusion were characterized by better total crude fat digestibility, nitrogen retention and AMEN values, compared to raw seeds. Higher ileal digestibility was confirmed in numerous amino acids, except lysine, threonine and valine (P≤0.05). By feeding the broilers with diets consisting of 10 to 30% of lupine seeds post extrusion (experiment II), improved apparent fat digestibility, apparent nitrogen retention and AMEN values were achieved in young chickens (P<0.01). Using 10 and 20% of lupine in the diets showed significant positive effects of extrusion on body weight gains, feed intake and feed conversion rate. The performance indices of chickens were drastically decreased by use of 25% ratio of both raw and extruded yellow lupine in the diet. This effect was heightened by a 30% share in feed mixtures.

Sorghum grain (SG) contained more crude protein (103.5 g/kg) and ash (17.0 g/kg) but less crude fiber (17.7 g/kg) and total lipid (22.6 g/kg) than corn. The SG contained 0.37% ± 0.02 tannin, had a higher apparent metabolizable energy value than corn or wheat and contained all of the amino acids considered essential for chickens at levels in general between those of corn and wheat. Two experiments were carried out to ascertain the nutritive value of SG as a partial replacement for corn and wheat in practical poultry diets using 320 male and 320 female Cobb chicks in each. Starter (finisher) diets fed from 0–21 days (22–42 days) contained the following levels of SG: 15 (19); 30 (39); 45 (58)%. The diets were isoenergic and isonitrogenous. The inclusion of up to 45% SG in the starter diet and up to 58% in the finisher diet had no significant effect on mortality, live body weight, feed conversion or percentage of grade A carcasses.

Abstract. The effect of different phytases on the performance response, nutrient utilization and tibia characteristics of chickens was investigated. The five pelleted diets were the following: positive control (PC) with added monocalcium phosphate; negative control (NC) formulated with equivalency values of phytase for Ca and digestible P; and three further diets where different phytases were individually added to the NC diet at 500 FTU/kg. The phytases were derived either from Aspergillus (phytase I), or E. coli (phytases II and III). Compared to PC, the performance parameters, as well as apparent metabolizable energy (AMEn), mineral retention, bone breaking force and tibia mineral content were suppressed by the reduction of dietary Ca and digestible P. All phytases enhanced the overall body weight gains and feed conversion ratio in comparison with NC, but none outperformed PC. Only phytase II improved AMEn compared to NC and PC group. However only phytase I outperformed NC group in terms of mineral retention and P retention was higher than phytase II and III. No significant differences were observed in fat digestibility and N retention. Bone strength among phytases did not differ and all improved this parameter compared to the NC diet. However, even though all phytases enhanced tibia minerals content, the improvement was less pronounced with phytase III. Moreover, the differences in all analysed tibia minerals between phytase III and II were significant suggesting that even among 6-phytases derived from and expressed in the same organism, different efficacy or mode of action can occur.
