Abstract
The aim of the present study was to evaluate the efficacy of Bacillus-based probiotic in pullet to lay period. A total of 12-wk-old 384 Hy-line Brown pullets (initial BW of 1.05 kg, 8 replications; 16 birds per replication pen) were used in a 6-wk feeding trial. Birds were blocked based on BW and randomly allotted to 1 of 3 dietary treatments that consisted of basal diet as CON; GPM, basal diet+ (GalliPro Max/B. subtilis, 500 g/ton); GPT, basal diet+ (GalliPro Tect/B. licheniformis, 500 g/ton). During the pullet stage, birds that were fed CON diet and CON diet supplemented with either 500 g/ton B. sublitis or B. licheniformis were randomly assigned to 1 of 7 treatments with 9 replications (6 birds per replication) during lay period. For this, a total of 162 birds fed CON diets were randomly chosen and subdivided into 3 groups and fed CON, GPM, and GPT diets. From the birds that were fed either GPM or GPT diet at pullet phase, about 108 birds from each treatment were randomly chosen and were subdivided into 2 treatments and fed either GPM or GPT diet. The feed intake was higher (P < 0.05) in GPT treatment and lower (P < 0.05) in GPM treatment compared with CON during the pullet period. In addition, the excreta Escherichia coli counts were reduced (P < 0.05) in pullets fed GPT diet. The egg production rate significantly increased (P < 0.05) for layers fed GPM diet and a slight increase was also seen for GPT treatment birds compared with CON during week 32. During the lay period, the average mean values for albumen height and yolk color at week 25 to 45 were higher (P < 0.05) for GPM fed birds compared with those fed GPT and CON diets. In conclusion, Bacillus-based probiotic supplementation in the diet conferred some positive effects during pullet to lay period.

Abstract
Apparent ileal digestibility (AID) of energy, dry matter (DM), nitrogen (N) and amino acids and standardized ileal digestibility (SID) of amino acids in low quality soybean meals with different CP concentration (SBM 44% CP and SBM 48% CP) with or without 400 U β-mannanase/kg supplementation were evaluated in 20 cannulated barrows ((Landrace×Yorkshire)×Duroc) with an average BW of 25.08±3.42 kg. A N-free diet was used to determine basal endogenous losses of amino acids. The supplementation of β-mannanase improved (P0.05) AID of N and energy. The type of SBM (SBM 44% CP v. SBM 48% CP) had no effect on AID of DM, N and energy. β-mannanase improved (P<0.05) AID of sum of essential amino acids, arginine, histidine, lysine, valine and glycine. The SID of lysine was higher (P<0.05) in enzyme supplemented than in non-supplemented diets. Larger AID and SID of threonine and proline (P<0.05) were observed in SBM 48% CP than in SBM 44% CP. In conclusion, the supplementation of enzyme improved AID of arginine, histidine, lysine, valine and glycine, but it did not cause marked difference in SID of these amino acids except for lysine. The low nutrient digestibility of the SBM sources used in the present experiment might have favoured the positive effect of β-mannanase supplementation.

Abstract
A total of 192 Hy-Line Brown 40-week-old Salmonella-free layers were randomly assigned to 4 dietary treatments in a 5-wk experiment to test the efficacy of probiotics on egg production and quality, excreta and intestinal microbiota of laying birds challenged with Salmonella gallinarum. Dietary treatment comprised of (1) NC: ; basal diet, negative control, (2) PC: ; basal diet + oral S. gallinarum administration, positive control, (3) T1: ; basal diet + 0.1% Bacillus subtilis RX7 1 × 10(9) cfu/g + S. gallinarum administration and (4) T2: ; basal diet + 0.1% Bacillus methylotrophicus C14 1 × 10(9) cfu/g + S. gallinarum administration. All birds (n = 144) except NC were orally challenged with 1 ml suspension of 10(8) cfu/mL S. gallinarum KVCC BA 0700722 once at d 28 after the initiation of experiment. The egg production improved in post Salmonella-challenged birds whereas egg equality was improved during pre-challenge in probiotic supplemented birds compared to NC and PC. The Salmonella counts in the excreta were lower (P < 0.05) in T1 and T2 than PC at the end of the experiment whereas the Lactobacillus counts in the excreta were higher (P < 0.05) in T1 compared with NC. The Escherichia coli counts in excreta were numerically lower in T1 and T2 than PC. In the small and large intestine, there was slight increase in Lactobacillus counts in T2 compared with PC. The Salmonella counts in small and large intestine tended to be lower in T1 and T2 as compared with PC. However, Salmonella counts in challenged birds not supplemented with probiotics were significantly higher than non-challenged birds.

Abstract
Bacillus-based feed additive was evaluated for its efficacy on growth performance, nutrient digestibility, fecal gas emission, and the consumption of time and amount of water for cleaning the pen of growing finishing pigs. A total of 120 growing pigs (23.59±1.41 kg) were used in a 16-wk feeding trial. Pigs were randomly distributed into 1 of 2 treatments on the basis of body weight and sex. There were 12 replicate pens per treatment, with 5 pigs (3 barrows and 2 gilts) per pen. Dietary treatments were CON which was basal diet, and T1 which was CON+62.5 ppm microbial feed additive that provided 1.47×10(8) cfu of Bacillus organisms per gram of supplement. During the weeks 0 to 6, average daily gain (ADG) in T1 treatment was higher (p<0.05) than CON, but no improvement in average daily feed intake (ADFI) and feed efficiency (G:F) was noted. During 6 to 16 weeks, no difference (p>0.05) was noted in growth performance. However, ADG was improved (p<0.05) and overall ADFI tended (p = 0.06) to improve in T1 compared with CON. At week 6, the co-efficient of apparent total tract digestibility (CATTD) of dry matter (DM) nitrogen (N) was increased (p<0.05) in T1 compared with CON. Fecal NH3 emission was decreased (p<0.05) in T1 compared with CON, at the end of 6th and 15th weeks. The time and water consumed for washing the pens were decreased (p<0.05) in T1 compared with CON. In conclusion, supplementation with Bacillus-based feed additive could improve the overall growth performances, increase the CATTD of DM and decrease the fecal NH3 content and the time and water consumed in washing the pens for growing-finishing pigs.

Abstract
Two hundred and sixteen Institut de Sélection Animale (ISA) brown layers (40 wks of age) were studied for 6 wks to examine the effect of microalgae powder (MAP) on egg production, egg quality, blood lipid profile, and fatty acid concentration of egg yolk. Dietary treatments were as follows: i) CON (basal diet), ii) 0.5% MAP (CON+0.5% Schizochytrium powder), and iii) 1.0% MAP (CON+1.0% Schizochytrium powder). From 44 to 46 wks, egg production was higher in 1.0% MAP treatment than in control treatment (linear, p = 0.034); however, there was no difference on the egg production from 40 to 43 wks (p>0.05). Serum triglyceride and total cholesterol were significantly reduced in the groups fed with MAP, compared to those in groups fed with control diets (Quadratic, p = 0.034 and p = 0.039, respectively). Inclusion of 0.5% MAP in the diet of layers improved egg yolk color, compared with hens fed with basal diet at 46 wks (quadratic, p = 0.044). Eggshell thickness was linearly increased in MAP-fed treatments at 46th wk (p<0.05). Concentration of yolk docosahexaenoic acid (DHA; C22:6n-3) was increased in treatment groups fed with MAP (linear, p<0.05). The n-6 fatty acids, n-6/n-3 fatty acid, and unsaturated fatty acid/saturated fatty acid were decreased in treatment groups fed with MAP (linear, p<0.05). These results suggest that MAP improved the egg production and egg quality, and may affect serum lipid metabolites in the layers. In addition, MAP increases yolk DHA levels, and deceases n-6/n-3 fatty acid ratio.

Abstract
A total of 120 finishing pigs ([Yorkshire×Landrace]×Duroc) with an average body weight (BW) of 49.72 ±1.72 kg were used in 12-wk trial to evaluate the effects of protected organic acids on growth performance, nutrient digestibility, fecal micro flora, meat quality and fecal gas emission. Pigs were randomly allotted to one of three dietary treatments (10 replication pens with 4 pigs per pen) in a randomly complete block design based on their initial BW. Each dietary treatment consisted of: Control (CON/basal diet), OA1 (basal diet+0.1% organic acids) and OA2 (basal diet+0.2% organic acids). Dietary treatment with protected organic acid blends linearly improved (p<0.001) average daily gain during 0 to 6 week, 6 to 12 week as well as overall with the increase in their inclusion level in the diet. The dry matter, N, and energy digestibility was higher (linear effect, p<0.001) with the increase in the dose of protected organic acid blends during 12 week. During week 6, a decrease (linear effect, p = 0.01) in fecal ammonia contents was observed with the increase in the level of protected organic acid blends on d 3 and d 5 of fermentation. Moreover, acetic acid emission decreased linearly (p = 0.02) on d7 of fermentation with the increase in the level of protected organic acid blends. During 12 weeks, linear decrease (p<0.001) in fecal ammonia on d 3 and d 5 and acetic acid content on d 5 of fermentation was observed with the increase in the level of protected organic acid blends. Supplementation of protected organic acid blends linearly increased the longissimus muscle area with the increasing concentration of organic acids. Moreover, color of meat increased (linear effect, quadratic effect, p<0.001, p<0.002 respectively) and firmness of meat showed quadratic effect (p = 0.003) with the inclusion of increasing level of protected organic acid in the diet. During the 6 week, increment in the level of protected organic acid blends decreased (linear effect, p = 0.01) Escherichia coli (E. coli) counts and increased (linear effect, p = 0.004) Lactobacillus counts. During 12-wk of experimental trial, feces from pigs fed diet supplemented with organic acid blends showed linear reduction (p<0.001) of E. coli counts and the tendency of linear increase (p = 0.06) in Lactobacillus count with the increase in the level of organic acid blends. In conclusion, 0.2% protected organic acids blends positively affected growth performance, nutrient digestibility, fecal gas emission and meat quality in finishing pigs without any adverse effects on blood parameters.
