The following study evaluated effects of a xylanase and beta-glucanase combination on growth performance of broilers fed energy reduced versus nutritionally adequate maize-soybean meal-based diets. A total of 648, one-day-old male broilers (Ross 308) were assigned to floor-pens (24 birds/pen, nine pens/treatment, three treatments) in a randomised block design. Treatments included: (1) a nutritionally adequate positive control diet (PC); (2) a negative control (NC) diet in which energy, crude protein and digestible amino acids were reduced by 3.4% (-105 kcal apparent metabolisable energy), 2.3% and 1.2 to 3.0% vs PC, respectively; and (3) NC plus a xylanase and beta-glucanase combination that supplied 1,220 U xylanase and 152 U beta-glucanase per kilogram of final feed. All diets contained a background of 500 FTU/kg phytase and were offered to birds ad libitum. Birds fed NC showed reduced average daily gain (ADG) by -6.1% (P<0.05); increased feed conversion ratio (FCR) by 9.2 points (P<0.05), and overall (d 1-35) body weight corrected FCR which was increased by 9.4 points (P<0.05) vs the PC group. Enzyme supplementation increased final BW (+4.2%, P<0.05), ADG (+5.4%, P<0.05) and tended to reduce FCR (+7.5 points, P=0.054) from d 22-35 vs NC, without affecting average daily feed intake. Improvements in performance due to the enzyme combination were equivalent to performance on the PC diet in all cases. The results suggested that significant improvements in growth performance of broilers fed maize-soybean meal-based diets which had been reduced in energy and nutrients can be realised by supplementation with xylanase in combination with beta-glucanase.

Abstract The efficacy of a novel consensus bacterial 6-phytase variant (PhyG) to totally replace dietary inorganic phosphorus (Pi) was evaluated in grower pigs fed diets with reduced net energy (NE) and digestible amino acids (AA), using growth performance and total tract digestibility (ATTD) of nutrients as outcome measures. A total of 352 growing pigs (23.4 ± 1.3 kg) were randomized to 4 dietary treatments with 8 pigs/pen and 11 pens/treatment. Diets were corn, soybean meal, distiller’s dried grains with solubles and wheat middlings based, formulated by phase (Grower 1, 25 to 50 kg and Grower 2, 50 to 75 kg). The positive control (PC) diet provided adequate energy and nutrients. A negative control diet was formulated without Pi (0.12% STTD P) and reduced Ca (-0.12 to -0.13 percentage points), NE (-32 kcal/kg) and essential AA (-0.15 to 0.3 percentage points) vs. PC. The NC was supplemented with 500 or 1,000 FTU/kg of PhyG. Data were analyzed by analysis of variance and orthogonal polynomial were used for linear response to increasing PhyG. Nutrient reductions in the NC reduced (P &lt; 0.05) average daily gain (ADG) during both phases and overall, increased (P &lt; 0.05) feed conversion ratio (FCR) and tended to reduce (P &lt; 0.1) feed intake during Grower 1 and overall, vs. PC. Supplementation of PhyG showed linear improvement (P &lt; 0.05) in FCR during Grower 1 and ADG during Grower 2 and PhyG at 1,000 FTU/kg maintained a similar growth performance compared to PC. Addition of PhyG improved (P &lt; 0.001) ATTD P and tended to improve ATTD of DE (P &lt; 0.1) in linear manner. In conclusion, the novel consensus phytase can replace Pi and compensate for the reduction of Ca, NE and digestible AA in grower pig diets with equal performance compared to the nutrients adequate positive control.

Soy protein concentrate improves nutrient utilization and growth performance compared to soybean meal, and diets with a low crude protein (CP) level decreases diarrhoea. The objectives were to (1) test a low CP diet based on different soy products, and (2) to test a very-low CP diet (15.1%) with amino acids (AA) on diarrhoea and productivity. A total of 5,635 weaned pigs (~28 days), were assigned to five dietary treatments; PC (positive control): Standard CP levels (192, 189, 191 g/kg CP) with 2500 ppm ZnO; NC (negative control): Same as PC without ZnO; SP (Soy protein concentrate): Low CP levels (176, 174, 191 g/kg CP); SB (Soybean meal): Low CP levels (177, 176, 191 g/kg CP); and XLA (X-low CP + AA): Very low CP levels (154, 151, 191 g/kg CP) with AA. The PC and XLA diets reduced diarrhoea by 41 and 61%, respectively, compared to the NC group, while no difference between SB and SP were observed. The XLA diet reduced feed intake and daily gain compared with PC and NC, where SP, SB, and XLA had a poorer feed conversion compared with PC. Conclusively, the SP and SB low-protein diets did not reduce diarrhoea or growth performance, whereas the XLA diet decreased both diarrhoea and performance.

Abstract An experiment was conducted to test the hypothesis that inclusion of the direct fed microbial Clostridium butyricum in diets for weanling pigs will improve growth performance, systemic immune function, microbiota composition, and gut morphology in weaned pigs. A total of 275 newly weaned pigs (20 ± 2 d of age) with an average initial BW of 6.4 ± 0.8 kg were allotted to a randomized complete block design with 11 pens per treatment. Diets included a positive control diet containing Carbadox, a negative control diet without Carbadox, and three treatment diets in which 1,250 × 108 cfu/kg, 2,500 × 108 cfu/kg, or 3,500 × 108 cfu/kg of C. butyricum was added to the negative control diet. A two-phase feeding program was used (phase 1, 14 d; phase 2, 21 d). At the conclusion of the experiment (day 35), a blood sample was collected from one pig per pen (11 pigs per treatment) and this pig was then euthanized and digesta and tissues samples were collected. Results indicated that for the overall phase, pigs fed the positive control diet had greater (P &lt; 0.05) ADG and ADFI and tended (P = 0.064) to have greater final BW than pigs fed the negative control diet. The ADG and G:F increased and then decreased as increasing doses of C. butyricum were included in the diet (quadratic, P &lt; 0.05). The concentration of tumor necrosis factor-α was less (P &lt; 0.05) in pigs fed the positive control diet compared with pigs fed the negative control diet or diets containing C. butyricum. Crypt depth tended (P = 0.08) to be less in pigs fed the negative control diet compared with pigs fed the positive control diet and villus height tended to increase as the doses of C. butyricum increased in the diets (quadratic, P = 0.08). Villus height also tended (P = 0.084) to be greater in pigs fed diets containing C. butyricum compared with pigs fed the positive control diet. Crypt depth increased as the dose of C. butyricum increased (quadratic, P &lt; 0.05) and villus width at the bottom tended to increase (linear, P = 0.072) as the dose of C. butyricum increased in the diet. Alpha and beta diversity indices of ileal and colonic microbiota were not affected by diet. In conclusion, addition of 1,250 × 108 cfu/kg of C. butyricum, but not greater levels, to diets fed to weanling pigs increased growth performance and tended to increase villus height and crypt depth, but changes in the abundance of intestinal microbiota were not observed.

ABSTRACT The objective of this study was to evaluate the use of an enzyme complex-α-amylase, ß-glucanase, phytase, cellulase, xylanase and protease-in the feed of swine in growing and finishing phases, by assessing their performance (daily weight gain, daily feed intake, and feed conversion), dry matter, crude protein, and crude energy apparent digestibility, and the feed costs. Eighty pigs-castrated males, and females-of approximately 63 days of age and initial weight of 20.18±1.98 kg were distributed in a 5×2 factorial arrangement (diet × sex), in a randomized block design, with eight replications. The treatments used were: positive control diet consisted of 3,300 kcal/kg in the growth-I phase, and 3,250 kcal/kg in the growth-II and finishing phases; negative control diet with energy reduction of 85 kcal/kg of metabolizable energy (ME) (NC85); NC85 diet with addition of enzyme complex (EC85); negative control diet with energy reduction of 100 kcal/kg ME (NC100); NC100 diet with addition of enzyme complex (EC100). The addition of the enzyme complex to the diet with energy reduction of 100 kcal/kg ME increased the digestible protein content of the diet for the swine in the growth-II phase. The addition of the enzyme complex to the diet with energy reduction of 85 and 100 kcal/kg ME increased the digestible energy content of the diets for the swine in the finishing phase. The use of enzyme complex in diets with reduction of 85 kcal/kg ME for male swine in growing and finishing phases is recommended for improving feed conversion and economic efficiency during the growth-I phase. The use of enzyme complex is not justified for female swine.

Abstract The capacity of a novel consensus bacterial 6-phytase variant (PhyG) to entirely replace dietary inorganic phosphorus (Pi) source in grower pigs fed diets with reduction of calcium (Ca), net energy (NE) and digestible amino acids (AA) was evaluated, using growth performance and apparent total tract digestibility (ATTD) of nutrients as outcome measures. A total of 352 mixed-sex pigs (initial BW 23.4 kg) were randomized to 4 treatments, 8 pigs/pen and 11 pens/treatment. Diets were corn-soybean meal-based and formulated by phase (grower 1, 25 to 50 and grower 2, 50 to 75 kg BW). The positive control diet (PC) provided adequate nutrients and a negative control diet (NC) was formulated without Pi (1.2 g/kg ATTD P) and reduced in Ca (-0.12 to -0.13 percentage points), NE (-32 kcal/kg) and digestible essential AA (-0.004 to -0.026 percentage points) vs. PC. Two further treatments comprised the NC plus 500 or 1,000 FTU/kg of PhyG. Data were analyzed by ANOVA, mean contrasts and orthogonal polynomial regression. Nutrient reductions in the NC reduced (P &lt; 0.05) average daily gain (ADG) during grower 1 and overall (73 to 136 days of age), increased (P &lt; 0.05) feed conversion ratio (FCR) during grower 1 and overall and tended to reduce (P &lt; 0.1) average daily feed intake (ADFI) during grower 2 and overall, vs. PC. Phytase supplementation improved (P &lt; 0.05) FCR during grower 1, ADG during grower 2 and overall, ATTD of DM and P, and tended to improve DE (P = 0.053) in a linear dose-dependent manner. PhyG at 1,000 FTU/kg resulted in growth performance (all measures, all phases) equivalent to PC. The findings demonstrate that PhyG at 1,000 FTU/kg totally replaced Pi in complex grower pig diets containing industrial co-products, compensated a full nutrient matrix reduction and maintained performance.

Quadratic Effects

Abstract An experiment was conducted to test the hypothesis that a Buttiauxella phytase expressed in T. reesei can compensate the reduction in standardized total tract digestible (STTD) P, Ca, digestible energy (DE), and standardized ileal digestible (SID) AA in diets for pigs without impaired growth performance. A positive control diet (PC) was formulated to meet the requirement for STTD P and total Ca (0.33% STTD P and 0.60% Ca). A negative control diet (NC) was formulated with 0.18% STTD P and 0.45% Ca and with reduction of DE by 43 kcal/kg and SID AA by 0.01–0.02% vs. PC. Adding 250, 500, or 1,000 phytase units (FTU) per kg to the NC diet for a total of 5 experimental diets formulated three additional diets. A total of 155 pigs (BW: 8.77 ± 1.38 kg) were allotted to the 5 treatments, and there were 8 replicate pens per treatment. The experiment was conducted for 21 d. Pigs were weighed at the beginning and conclusion of the experiment, and daily feed allotments were recorded. Average daily gain (ADG), average daily feed intake (ADFI), and gain: feed ratio (G:F) were calculated for each treatment. Data were analyzed using contrast statements to compare PC and NC, PC and phytase, and to determine linear and quadratic effects of phytase. Results indicated that pigs fed the NC diet had reduced (P &lt; 0.05) ADG and G:F compared with pigs fed the PC diet (Table 1). Adding phytase to NC increased ADFI (linear, P &lt; 0.05) and ADG (quadratic, P &lt; 0.05) with the greatest values for the 1,000 FTU treatment. Including phytase in the diet also resulted in a quadratic increase (P &lt; 0.05) in G:F. In conclusion, Buttiauxella phytase may be included in diets with reduced nutrients and energy for weanling pigs without compromising pig growth performance.

An experiment was conducted to study the influence of isoamylase supplementation to maize-soybean diets on productive performance and amylase activities of broilers from 1 to 42 d of age.The results showed that different dose of isoamylase（300g/T,600 g/T,900 g/T, containing 3000IU of isoamylase/g）in the maize - soybean meal diet significantly affected the performance of broilers within 1-42 days. Within 1-21 days , the average daily gain(ADG) of experimental groups( experiment I (E I) experiment II (E II) experiment III (E III) ) improved by 3.2% -10.32%(P>0.05) compared with the control groups(negative control(NC) and positive control(PC)), average daily feed intake(ADFI) improved by 0.63%-7.43%(P>0.05), while feed conversion ratio decreased by 0.55%-4.43%(P>0.05); Within 21-42 days , the ADG of experimental groups decreased by 1.38%-4.84% and ADFI by 11.89%-15.58% (P<0.05), feed conversion ratio by 5.41%-7.54% compared with that in the NC group; Within 1-42 days , the ADG of experimental groups improved by 0.54%-4.06%(P>0.05), while ADFI decreased by 0.75%-11.83% (P<0.05), and feed conversion ratio by 3.97%-7.52% (P>0.05) compared with those in the negative control. Isoamylase supplementation influenced amylase activity of various parts of the chyme in digestive tract and the tissues of small intestine and pancreas. 21 d, the amylase activity in experimental groups improved by 4.67%-79.29%(P<0.05) compared with PC, α-amylase activity in the majority experimental groups were lower than PC group, but the difference was not significant(P>0.05).

An “Amino acid (AA) partial deletion method” was used in this experiment to study the limiting sequences and appropriate ratio of lysine (Lys), methionine (Met), and threonine (Thr) in the diets of 7- to 9-month-old Holstein heifers. The experiment was conducted for three months with 72 Holstein heifers (age = 22 ± 0.5 weeks old; BW = 200 ± 9.0 kg; mean ± standard deviation). Following an initial two weeks adaptation period, heifers were allocated to one of four treatments: a theoretically balanced amino acid diet (positive control [PC]; 1.00% Lys, 0.33% Met, and 0.72% Thr), a 30% Lys deleted diet (partially deleted Lys [PD–Lys]; 0.66% Lys, 0.33% Met, and 0.72% Thr), a 30% Met deleted diet (partially deleted Met, [PD–Met]; 1.00% Lys, 0.22% Met, and 0.72% Thr), and a 30% Thr deleted diet (partially deleted Thr [PD–Thr]; 1.00% Lys, 0.33% Met, and 0.45% Thr). Experimental animals were fed a corn–soybean meal-based concentrate and alfalfa hay. In addition, the animals were provided with supplemental Lys, Met, and Thr (ruminal bypass). The results found no differences in the growth performance and nitrogen retention between PD–Thr treatment and PC treatment (p > 0.05). The average daily gain (p = 0.0013) and feed conversion efficiency (p = 0.0057) of eight- to ninr-month-old heifers were lower in both PD–Lys and PD–Met treatment than those in PC treatment. According to growth performance, Lys was the first limiting AA, followed by Met and Thr. Moreover, nine-month-old Holstein heifers in PD–Lys treatment and PD–Met treatment had higher levels of serum urea nitrogen (p = 0.0021), urea nitrogen (p = 0.0011) and total excreted N (p = 0.0324) than those in PC treatment, which showed that nitrogen retention significantly decreased (p = 0.0048) as dietary Lys and Met levels decreased. The limiting sequence based on nitrogen retention was the same as that based on growth performance. The appropriate ratio of Lys, Met, and Thr in the diet based on nitrogen retention was 100:32:57. In summary, the limiting sequence and appropriate amino acid ratio of Lys, Met, and Thr for seven- to nine-month-old Holstein heifers fed a corn–soybean meal-based diet were Lys > Met > Thr and 100:32:57, respectively.

Abstract Two experiments were conducted to determine the efficacy of commercial products on growth performance of nursery pigs fed high fumonisin diets. In Exp. 1,350 pigs (241 × 600; DNA; initially 9.9 kg) were used with 5 pigs per pen and 14 pens per treatment. Five dietary treatments consisted of a positive control (low fumonisin, 4 ppm fumonisin; FB1 + FB2), negative control (50 ppm fumonisin;) and the negative control with one of three products (0.3% of Kallsil Dry, Kemin Industries Inc., Des Moines, IA; 0.3% of Feed Aid Wide Spectrum, NutriQuest, Mason City, IA; 0.17% of Biofix Select Pro, Biomin America Inc., Overland Park, KS). Diets were fed for 14 d. Pens were assigned to treatments in a randomized complete block design with initial weight as the blocking factor. Data were analyzed using nlme package in R program (version 3.5.2) with pen as experimental unit. Pigs fed the negative control, or diets with Kallsil Dry or Feed Aid had decreased (P&lt; 0.05) ADG, ADFI, and G:F compared with those fed the positive control and diet with Biofix. Pigs fed the positive control diet had decreased (P&lt; 0.05) d 14 serum sphinganine to sphingosine (Sa:So) ratio than those fed other diets. In Exp. 2, 300 pigs (241 × 600; initially 10.4 kg) were used and fed experimental diets for 28 d. Procedures were similar to Exp. 1 except there were 12 replicates per treatment and diets contained 30 ppm fumonisin. Pigs fed the negative control, or diets with Kallsil Dry or Feed Aid had decreased (P&lt; 0.05) ADG and G:F, and greater (P&lt; 0.05) d 14 and 28 Sa:So ratios compared with the positive control and diet with Biofix. In summary, adding Biofix to high fumonisin diets mitigated the negative effects of fumonisin while Kallsil Dry and Feed Aid did not.

Abstract Two experiments were conducted to determine the efficacy of various commercial products on growth performance of nursery pigs fed diets high in fumonisin. In experiment 1, 350 pigs (241 × 600; DNA, Columbus, NE; initially 9.9 kg) were used with five pigs per pen and 14 replicates per treatment. After weaning, pigs were fed common diets for 21 d before the experiment started. The five dietary treatments consisted of a positive control (low fumonisin), a negative control (60 mg/kg of fumonisin B1 + B2 in complete diet), and the negative control with one of three products (0.3% of Kallsil Dry, Kemin Industries Inc., Des Moines, IA; 0.3% of Feed Aid Wide Spectrum, NutriQuest, Mason City, IA; 0.17% of Biofix Select Pro, Biomin America Inc., Overland Park, KS). Diets were fed in mash form for 14 d and followed with a low fumonisin diet for 13 d. For the 14-d treatment period, pigs fed the positive control diet and Biofix Select Pro had greater (P &lt; 0.05) average daily gain (ADG), average daily feed intake (ADFI), and gain:feed (G:F) compared to those fed the high fumonisin negative control, or high fumonisin diets with Kallsil Dry or Feed Aid Wide Spectrum. Serum sphinganine to sphingosine ratios (SA:SO) were greater (P &lt; 0.05) in all pigs fed high fumonisin diets compared to the positive control. In experiment 2, 300 pigs (241 × 600; DNA; initially 10.4 kg) were used. Procedures were similar to experiment 1 except there were 12 replicate pens per treatment, high fumonisin diets contained 30 mg/kg fumonisin, and experimental diets were fed for 28 d. Similar to experiment 1, pigs fed the positive control diet and treatment with Biofix Select Pro had greater (P &lt; 0.05) ADG and G:F, and lower (P &lt; 0.05) serum SA:SO compared to pigs fed the high fumonisin negative control, or high fumonisin diets with Kallsil Dry or Feed Aid Wide Spectrum. In summary, pigs fed diets containing 60 mg/kg of fumonisin for 14 d or 30 mg/kg of fumonisin for 28 d had poorer ADG and G:F and greater serum SA:SO compared to pigs fed a diet with less than 5 mg/kg of fumonisin. Adding Biofix Select Pro to diets appeared to mitigate the negative effects of high fumonisin concentrations, while Kallsil Dry and Feed Aid Wide Spectrum did not.
