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.

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.

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.

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.

AbstractOne hundred and eighty piglets (24 days old, 6·0 kg live weight) were used to investigate interactions between lactose, avilamycin and inulin on growth performance and nutrient digestibility in weaned piglets. The piglets were blocked on the basis of live weight and within each block assigned to one of six dietary treatments (six replicates (pens) per treatment). The piglets were offered diets containing either a low (175 g/kg) or high (295 g/kg) lactose levels with one of the following food additives (1) 0 supplementation (2) avilamycin (60 mg/kg) or (3) inulin (15 g/kg) in a 2 × 3 factorial arrangement. The starter diets were offered for 21 days and all diets contained chromium III oxide at 150 p. p. m. There was an interaction (P< 0·05) between lactose level and both avilamycin and inulin on average daily gain (ADG) during the starter period (days 0 to 21). The pigs receiving 295 g/kg lactose level had a higher overall ADG than pigs receiving 175 g/kg lactose level. However, there was no difference between 295 g/kg lactose and 175 g/kg lactose in ADG when the diets were supplemented with avilamycin or inulin. There was an interaction between lactose level and inulin in the apparent digestibility of gross energy (GE) and nitrogen (N) (P< 0·05). The inclusion of inulin with 175 g/kg lactose increased GE digestibility compared with the 175 g/kg lactose only diet. However, the inclusion of inulin with 295 g/kg lactose had no effect on GE digestibility. The inclusion of inulin with 295 g/kg lactose reduced N digestibility compared with the inclusion of inulin at 175 g/kg lactose. However, there was no difference in N digestibility between 175 and 295 g/kg lactose only diets. In conclusion, there was no benefit in terms of pig growth rate to supplementing diets high in lactose with either inulin or avilamycin. However, the inclusion of inulin improved the energy digestibility of diets low in lactose.

Dietary Treatments

A total of 150 crossbred pigs [(Duroc × Yorkshire) × Landrace; body weight (BW) = 5.74 ± 1.15 kg; weaned at day 21 after birth] were assigned to one of five dietary treatments (six pens per treatment and five pigs per pen) by BW and sex (two barrows and three gilts) for a 6 wk experiment. The pen was considered the experimental unit in the statistical model. Treatments were corn–soybean meal diets supplemented with 0.0033% tiamulin as well as 0%, 0.05%, 0.10%, or 0.20% fermented garlic (FG). The average daily gain, average daily feed intake (ADFI), and feed conversion ratio were linearly (p < 0.05) increased by FG inclusion during days 21–42 and days 0–42. Dietary supplementation of FG linearly increased (p < 0.05) the coefficient of apparent total tract digestibility of dry matter, nitrogen, and gross energy as well as blood immunoglobulin G concentration during week 6. The fecal ammonia (NH3), total mercaptan emissions, and Escherichia coli counts were linearly (p < 0.05) reduced by FG in the diet. Dietary supplementation of FG increased (p < 0.05) ADFI during days 21–42 and days 0–42 and reduced (p < 0.05) fecal NH3 emissions compared with pigs fed tiamulin. In conclusion, the results indicate that FG can enhance growth performance and digestibility, and reduce fecal E. coli counts as well as fecal gas emissions in weanling pigs.

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.

A total of 160 crossbred weanling pigs [(Landrace × Yorkshire) × Duroc, 28 days old] with an initial bodyweight of 8.01 ± 0.74 kg were used in a 42-day trial (Phase 1: Days 1–14, Phase 2: Days 14–42). The experiment was conducted to evaluate the effects of the inclusion of fermented oats (FO) to a corn and soybean meal-based diet on the performance of weanling pigs fed with high nutrient-density (HD) and low nutrient-density (LD) diets. Pigs were randomly distributed into one of four dietary treatments in a 2 × 2 factorial arrangement. Two levels of nutrient density [LD = 3323 (Phase 1: 1–14 days) and 3269 kcal/kg (Phase 2: 14–42 days); HD = 3446 (Phase 1: 1–14 days) and 3325 kcal/kg (Phase 2: 14–42 days), the differences in dietary energy were based on differences in the content of fish meal, animal fat, corn and FO [0%, 5% (Phase 1) or 2.5% (Phase 2)] were used according to the bodyweight and sex of pigs [8 replicate pens per treatment with 5 pigs in a pen (3 gilts and 2 barrows)]. During the overall trial period (Days 1–42), the average daily gain and gain:feed ratio of pigs fed HD and FO diets were significantly higher (P ≤ 0.05) than those of pigs fed with LD and non-fermented oats diets respectively. On Day 14, the apparent total tract digestibility of dry matter and nitrogen of the HD groups were significantly greater (P ≤ 0.05) than those of the LD groups. The apparent total tract digestibility of energy of the FO groups was significantly greater (P ≤ 0.05) than that of the non-fermented oats diet groups during the whole experimental period. Pigs fed with FO showed higher (P ≤ 0.05) ileal Lactobacillus and lower (P ≤ 0.05) Escherichia coli counts compared with those fed with the non-fermented oats diet. In conclusion, administration of FO to a LD diet demonstrated beneficial effects on the growth performance, nutrient digestibility and ileal microorganisms balance of weanling 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.

In experiment 1, a total of 30 weaning pigs were allotted to three dietary treatments to check the palatability of the dietary feed. Diet treatments were as follows: reference diets = basal diets + 0.05% saccharin (50% Saccharin-natrium), TRT1 = 0.03% saccharin–neotame mix (50% Saccharine-natrium + 2% Neotame), TRT2 = 0.02% neotame (10% Neotame), and TRT3 = 0.02% saccharin–neotame mix (10% Saccharine-natrium + 10% Neotame). TRT2 group was significantly higher than other treatments in palatability (P < 0.05). In experiment 2, a total of 52 weaning pigs were allotted to four dietary treatments. In the average daily gain and average daily feed intake over 1 wk, the TRT2 group was significantly higher than the TRT1 and TRT3 groups (P < 0.05). The concentration of triglyceride in the blood was highest in the TRT1 treated group and the lowest in the TRT2 group (P < 0.05). The Lactobacillus was significantly higher in the TRT2 and TRT3 treatments compared with 0.05% saccharin (50% Saccharine-natrium) (P < 0.05). There was no significant difference in the number of Escherichia coli (P < 0.05). In conclusion, diets supplemented with neotame could improve palatability, and artificial sweeteners can affect nutrient digestibility, blood characteristic, and fecal microbiota.
