This study was conducted to evaluate the effect of carbohydrases on growth performance, nutrient digestibility, blood profiles, and fecal microbiota in weanling pigs fed reduced energy diet. A total of 160 crossbred [(Yorkshire × Landrace) × Duroc)] weanling pigs with an initial body weight (BW) of 7.23 ± 1.08 kg were used in this 42 d trial. Pigs were randomly allocated in one of the following four dietary treatments: (1) CON, basal diet [net energy (NE) 2545 kcal kg−1]; (2) LE, low-energy diet (NE 2470 kcal kg−1); (3) LEC1, LE + 0.1% carbohydrase; and (4) LEC2, LE + 0.2% carbohydrase based on the sex and BW. There were eight replications (pens) per treatment with five pigs (two male and three female) per pen. During day 0–7, pigs fed with LE diet had lower (P < 0.05) average daily gain (ADG) and average daily feed intake than those fed with CON and LEC2 diets. LE group reduced (P < 0.05) ADG throughout the experiment compared with CON and LEC2 groups. LE group reduced (P < 0.05) the digestibility of dry matter, nitrogen, and gross energy compared with LEC2 diet. Taken together, LE diet caused detrimental effects on growth performance and nutrient digestibility in weanlings, whereas the addition of carbohydrases (0.2%) partially counteracted these negative effects.

Abstract This study was conducted to evaluate the effects of carbohydrases on growth performance, nutrient digestibility, blood profiles and fecal microbiota in weanling pigs fed reduced energy diet. A total of 160 cross-bred [(Yorkshire × Landrace) × Duroc)] weanling pigs with an initial BW of 7.23 ± 1.08 kg were used in this 42-day trial. Pigs were randomly allocated in 1 of the following 4 dietary treatments: (1) PC, positive diet (NE 2,545 kcal/kg); (2) NC, negative diet (NE 2470 kcal/kg); (3) NC1, NC + 0.1% carbohydrases; (4) NC2, NC + 0.2% carbohydrases based on the sex and BW. There were 8 replications (pens) per treatment with 5 pigs per pen. During d 0-7, pigs fed NC diet had lower (P < 0.05) average daily gain (ADG) and average daily feed intake (ADFI) than those fed PC and NC2 diets. NC group reduced (P < 0.05) ADG throughout the experiment compared with PC and NC2 groups. NC group reduced (P < 0.05) the digestibility of dry matter, nitrogen and gross energy. Taken together, reduced energy diet caused detrimental effects on growth performance and nutrient digestibility in weanlings, while the addition of carbohydrases (0.2%) can partially counteract these negative effects.

Effect of timing of xylanase supplementation to weanling pigs and its effect on growth performance, nutrient digestibility, and fecal microbiota was investigated. A total of 128 weanling pigs [(Hampshire × Duroc) × (Yorkshire × Landrace); 6.2 ± 0.6 kg body weight (BW); weaning age: 21 d] were assigned to four treatments, with eight replicate pens and four pigs per pen. Treatments were a combination of two dietary treatments (without or with xylanase) in two periods; (period 1, days 0–14) and period 2 (days 14–42): xylanase–xylanase, xylanase–control, control–xylanase, and control–control. Fecal microbiota diversity and apparent total tract digestibility (ATTD) were determined. From days 0–14, pigs had lower (P < 0.01) BW, average daily gain (ADG), and feed efficiency when xylanase was included in the diets. The final BW (P < 0.05) and overall ADG (P < 0.02) at day 42 were greater when xylanase was supplemented from day 14 compared with supplementation from day 0. The apparent ileal digestibility and ATTD of dry matter, gross energy, nitrogen, and phosphorus were increased (P < 0.05) by xylanase. Xylanase significantly decreased (P < 0.05) the relative abundance of Veillonella spp. and tended (P = 0.08) to decrease the relative abundance of Megasphaera spp. in period 2 compared with the non-supplemented group.

This study was conducted to evaluate the effect of supplementation of different flavors (apple and anise) on growth performance, nutrient digestibility, blood profiles, and carcass quality in growing–finishing pigs. A total of 96 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 28.2 ± 0.7 kg were randomly assigned to one of the following three treatments: (1) CON, basal diet; (2) APF, basal diet + 0.05% apple flavor; (3) ANF, basal diet + 0.05% anise flavor, according to their BW and sex in this 15 wk experiment. There were eight replications (pens) per treatment and four pigs per pen (two barrows and two gilts). During week 0–5, pigs fed ANF diets had greater (p < 0.05) average daily gain (ADG) and average daily feed intake than those fed CON and APF diets. Dietary ANF treatment increased (p < 0.05) ADG during 0–15 wk compared with CON treatment. At the end of 5 wk, the apparent total tract digestibility of nitrogen in ANF treatment was improved (p < 0.05) compared with that in CON treatment. Dietary treatments did not affect the studied traits of carcass and meat quality. The inclusion of anise flavor increased ADG, but apple flavor had no effect on growth performance in growing–finishing pigs.

A total of 150 weaning pigs (7.53 ± 1.23 kg) were randomly assigned to three treatments consisting of basal diet, and the basal diet supplemented with 300 and 600 mg kg−1 of probiotics, respectively, in a 42 d trial. The incremental levels of probiotics linearly increased average daily gain during week 1 and through the overall experimental period (P < 0.05). The average daily feed intake, body weight, and the apparent total tract digestibility of dry matter, nitrogen, and gross energy also increased (P < 0.05) with the increased level of probiotics. A significant reduction in Escherichia coli counts (P = 0.0037) and increase (P = 0.0016) in Lactobacillus counts were observed on day 42.

Abstract Canola meal (CM) is widely included in swine diets, but its fiber matrix compromises its nutritional value. Whether steam-explosion with high pressure can increase nutrient digestibility of CM and hence growth performance in pigs is unknown. To explore, Brassica napus CM was processed with steam pressure at 700 or 1,100 kPa for 5 min followed by a sudden release of pressure to produce steam-exploded CM7 and CM11, respectively. Four diets containing 20% CM, CM7, CM11, or soybean meal (SBM) were formulated to provide 2.3 Mcal net energy (NE)/kg and 5.1 g standardized ileal digestible lysine/Mcal NE. From 2 weeks post-weaning, 256 pigs (BW, 10 kg) were fed the 4 diets for 4 weeks in a randomized complete block design with 16 blocks and 4 pigs per pen. Apparent total tract digestibility (ATTD) of dry matter (DM), crude protein (CP), and gross energy (GE) was 4.8, 4.3 and 3.7%-units lower (P < 0.05), respectively, for the 3 CM diets than the SBM diet, whereas diet digestible energy (DE) value was not different. Steam-explosion of CM did not affect diet ATTD of DM and GE, but reduced (P < 0.05) diet ATTD of CP. For the entire trial (day 1–28), steam-explosion at either 700 or 1,100 kPa increased (P < 0.05) average daily feed intake (ADFI) of CM, but the CM diet had lower (P < 0.05) ADFI than the SBM diet. Average daily gain (ADG) did not differ among the 4 diets. Consequently, feed efficiency (G:F) was greater (P < 0.05) for the 3 CM diets than the SBM diet. In conclusion, steam-explosion of CM did not increase diet nutrient digestibility or growth performance of weaned pigs.

A total of 90 finishing pigs (52 ±1.46kg) were randomly assigned to 1 of 3 dietary treatments as: TRT1- (CON (basal diet)), TRT-2 (CON + 0.05% yeast hydrolysate (YH)), TRT3 – (CON + 0.1% YH) for 8 weeks trial. Each treatment had 6 replications and 5 (3 gilts and 2 barrow) pigs pen. In weeks 4 and 8, YH supplement linearly increased (P < 0.05) body weight. Moreover, average daily gain was also linearly increased (P < 0.05) with YH supplementation in week 4 and the overall trial period. At the end of the trial, apparent total tract digestibility of dry matter, nitrogen, and gross energy was linearly increased in pigs fed YH supplementation. In addition, fecal lactobacillus counts, IGF-1 concentration, and the lean meat percentage was linearly increased by YH supplementation. Also, YH supplementation elicited a linear reduction on drip loss during days 3, 5, and 7. In summary, dietary yeast hydrolysate supplement positively enhanced the growth performance, nutrient digestibility, lactobacillus count and reduce the drip loss traits of finishing pig. Thus, we infer that the application 0.1% S. cerevisiae yeast hydrolysate can enhance the growth efficiency of finishing pigs.

The study was aimed to evaluate the effects of dietary inclusion of an enzyme blend on growth performance, apparent total track digestibility (ATTD) of dry matter (DM), nitrogen (N), gross energy (GE), fecal microbial population, noxious gas emissions and meat quality of pigs fed corn–soybean meal-based diets for a 16-week feeding trial. A total of 180 growing pigs (body weight of 23.3 ± 2.51 kg) were used and randomly allotted to one of three dietary treatments (positive control (PC, basal diet); negative control (NC, −150 kcal/kg of PC); A1 (NC + 1% enzyme blend)). Overall, dietary inclusion of the enzyme blend increased (p < 0.05) body weight, average daily gain and gain:feed ratio without effecting average daily feed intake. An increase was observed in ATTD of DM (p = 0.027) and GE (p = 0.026) at week 16 and 6, respectively. Dietary inclusion of the enzyme blend increased the beneficial effects on fecal microbiota counts such as Lactobacillus with a reduced presence of E. coli during the entire experiment (p < 0.05). Further, positive effects (p < 0.05) were observed on back-fat thickness and carcass weight of pigs, along with the results of reduced levels of NH3 emissions (p = 0.032) at week 16. Thus, the study suggested that the dietary enzyme blend supplement had improving effects on growth performance, ATTD of nutrients, fecal microbial counts and meat quality in pigs.

In the present study, two experiments were conducted to (1) evaluate the effect of laminarin and/or fucoidan on ileal morphology, nutrient transporter gene expression and coefficient of total tract apparent digestibility (CTTAD) of nutrients and (2) determine whether laminarin inclusion could be used as an alternative to ZnO supplementation in weaned pig diets. Expt 1 was designed as a 2 × 2 factorial arrangement, comprising four dietary treatments (n 7 replicates, weaning age 24 d, live weight 6·9 kg). The dietary treatments were as follows: (1) basal diet; (2) basal diet+300 ppm laminarin; (3) basal diet+240 ppm fucoidan; (4) basal diet+300 ppm laminarin and 240 ppm fucoidan. There was an interaction between laminarin and fucoidan on the CTTAD of gross energy (GE) (P< 0·05) and the expression of sodium–glucose-linked transporter 1 (SGLT1/SLC5A1) and GLUT1/SLC2A1 and GLUT2/SLC2A2 (P< 0·05) in the ileum. The laminarin diet increased the CTTAD of GE and increased the expression of SGLT1, GLUT1 and GLUT2 compared with the basal diet. However, there was no effect of laminarin supplementation on these variables when combined with fucoidan. Expt 2 was designed as a complete randomised design (n 8 replicates/treatment, weaning age 24 d, live weight 7·0 kg), and the treatments were (1) basal diet, (2) basal diet and laminarin (300 ppm), and (3) basal diet and ZnO (3100 ppm, 0–14 d, and 2600 ppm, 15–32 d post-weaning). The laminarin diet increased average daily gain and gain:feed ratio compared with the basal diet during days 0–32 post-weaning (P< 0·01) and had an effect similar to the ZnO diet. These results demonstrate that laminarin provides a dietary means to improve gut health and growth performance post-weaning.

The objective of the present study was to evaluate the effects of MCFA and probiotic (Enterococcus faecium DSM 7134) supplementation on growth performance, nutrient digestibility, blood profiles, faecal score, excreta microbiota, and excreta noxious gas emission in weanling pigs. A total of 140 weanling pigs [(Yorkshire &times; Landrace) &times; Duroc] were allotted to four treatments groups of seven replicates/treatment and five pigs/replicate. The four experimental diets included: CON diet (basal diet); T1 (CON + MCFA 0.2%); T2 (CON + probiotic 0.01%) and T3 (CON + MCFA 0.2% + probiotic 0.01%). Growth performance, average daily gain (ADG), average daily feed intake (ADFI), gain-to-feed ratio (G : F), Nutrient digestibility: dry matter (DM), nitrogen (N), energy were determined along with blood profiles: glucose, blood urea nitrogen (BUN), creatinine, high density lipoprotein (HDL), low density lipoprotein (LDL), total cholesterol, triglyceride, Excreta bacteria: Lactobacillus, E. coli, Excreta gas emission: NH<sub>3</sub>, H<sub>2</sub>S, total mercaptans, acetic acid and faecal scores. Overall, average daily gain (ADG) and G : F in T2 and T3 treatment groups was higher than in T1 and controls. In blood profiles, glucose levels were found to be increased in week two and six in the treatment groups compared to controls. In addition, the nutrient digestibility of DM, N and energy were found to be increased significantly in T2 and T3 when compared to T1 and controls. There was no significant difference observed between the groups for faecal score, microflora and noxious gas emission. In conclusion, dietary MCFA and probiotic supplementation in weanling pigs are efficacious alternatives to antibiotics, and can improve health status and performance.

In total, 28 multiparous sows (n = 7) and their litters were used to determine the effects of levan-type fructan supplementation on growth performance, nutrient digestibility, blood profiles, and fecal noxious gas emissions. The dietary treatments included (1) CON, basal diet; (2) FC1, CON + 0.1% fructan; (3) FC2, CON + 0.2% fructan; and (4) FC3, CON + 0.3% fructan. No significant differences were observed (P > 0.05) in body weight (BW), average daily feed intake, or back fat loss in lactating sows among treatments. However, blood lymphocyte concentrates were higher (P < 0.05) in sows fed levan-containing diets than in those fed the CON diet. Weaning BW and overall average daily gain (ADG) of piglets in the FC3 treatment were higher (P < 0.05) than piglets in the CON treatment. Blood lymphocytes and nutrient digestibility of sows, as well as the weaning BW and the ADG of piglets were increased linearly (P < 0.05) as the concentration of levan increased in the diet. The diarrhea score of piglets and the fecal gas emissions of sows decreased linearly (P < 0.05) as dietary levan increased. In conclusion, levan supplementation did not affect feed intake or decrease back fat loss of lactating sows, but it improved nutrient digestibility and immune ability, decreased fecal noxious gas emissions of lactating sows, and it improved growth performance and reduced diarrhea in piglets.
