Effects of multistrain probiotics on growth performance, nutrient digestibility, blood profiles, faecal microbial shedding, faecal score and noxious gas emission in weaning pigs

Abstract Phytogenic feed additives have become attractive alternatives for use in animal diets. The objective of the present study was to evaluate the effect of a phytogenic-based feed additive on growth performance, nutrient digestibility, blood profiles, fecal noxious gas emission, and intestinal morphology of weaning pigs after dietary challenge with E. coli K88. A total of 120 crossbred pigs [(Yorkshire × Landrace) × Duroc)] with an initial body weight (BW) of 6.09 ± 0.96 kg (21 d of age) were assigned randomly to 1 of the 4 dietary treatments. Each pen housed 5 pigs, and there were 6 pens/treatment. Treatments included: T1, negative control (without antibiotics); T2, T1 + antibiotic; T3, T1 + 0.05% phytogenics; and T4, T1 + 0.2% commercial mix of organic acids. Overall, the average daily gain (ADG) with the T3 treatment was higher (P<0.05). At wk 1, the apparent total tract digestibility (ATTD) of dry matter (DM) was increased (P<0.05) with T4 treatment. The ATTD of ash with T3 and T4 treatments was greater (P<0.05). At wk 3, pigs fed with the T4 diet had a significantly higher (P<0.05) ATTD of DM. The ATTD of ash and calcium (Ca) was significantly increased (P<0.05) with the T4 treatment. Pigs fed with the T3 diet had a higher (P<0.05) ATTD of phosphorus (P). At wk 6, the ATTD of ash was significantly increased (P<0.05) with the T1 and T3 treatments. The data indicate that phytogenics positively affect growth performance of weaning pigs, indicating that their use as an alternative in the diets of weaning pigs can significantly improve ADG, under challenge with E.coli K88.

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 × Landrace) × 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.

Weaning Pigs

A total of 180, 4-week-old crossbred weaning piglets ((Yorkshire × Landrace) × Duroc; 6.67 ± 1.40 kg) were used in a 42 day experiment to evaluate the effect of dietary probiotics (Lactobacillus plantarum BG0001) on growth performance, nutrient digestibility, blood profile, fecal microbiota, and noxious gas emission. All pigs were randomly allotted to one of four treatment diets in a completely randomized block design. Each treatment had nine replicates with five pigs/pen (mixed sex) Designated dietary treatments were as: (1) basal diet (NC), (2) NC + 0.2% antibiotics (chlortetracycline) (PC), (3) NC + 0.1% L. plantarum BG0001 (Lactobacillus plantarum BG0001) (NC1), (4) NC + 0.2% L. plantarum BG0001 (NC2). On d 42, BW and G:F were lower (p < 0.05) in pigs fed NC diet compared with PC diet and probiotic diets. Throughout this experiment, the average daily gain increased (p < 0.05) in pigs when fed with PC and probiotic diets than the NC diet. The average daily feed intake was higher (p < 0.05) in pigs fed PC diet during day 0–7 and 22–42, and probiotic diets during day 0–7 compared with NC diet, respectively. The Lactobacillus count was increased and Escherichia coli count was decreased (p < 0.05) in the fecal microbiota of pigs fed probiotic diets, and E. coli were decreased (p < 0.05) when fed a PC diet compared with the NC diet on day 21. Moreover, the apparent total tract nutrient digestibility, blood profile, and the concentration of noxious gas emission had no negative effects by the probiotic treatments. In conclusion, dietary supplementation with L. plantarum BG0001 significantly improved the growth performance, increased fecal Lactobacillus, and decreased E. coli counts in weaning pigs.
