Quillaja Saponin

The purpose of this study was to evaluate the effects of dietary supplementation of Quillaja saponin (QS) on growth performance, nutrient digestibility, fecal microbiota, and fecal gas emission in growing pigs. A total of 50 crossbred growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 23.83 ± 1.95 kg were randomly assigned to 1 of 2 treatments for a 56-day trial with 5 replicate pens per treatment and 5 pigs (2 barrows and 3 gilts) per pen. Dietary treatments including control diet and control diet supplemented with 200 mg/kg QS. The average daily gain was significantly increased during days 0-56, while the fecal ammonia emission on day 56 and fecal coliform bacteria counts on day 28 were significantly decreased in pigs fed with QS containing diet. However, dietary supplementation of QS had no significant effects on apparent total tract digestibility. In conclusion, dietary supplementation of 200 mg/kg QS had beneficial effects on growth performance, fecal microbiota, and fecal gas emission in growing pigs. Considering the carry-over effects, the adaption period should be at least 28 days when supplementing 200 mg/kg QS to the diet of growing pigs for improving the growth performance.

Abstract This study was carried out to assess the effects of dietary supplementation of enzymatic bio-conversion of Scuterallia baicalensis (SB) extract on the growth performance, nutrient digestibility, fecal microbiota, fecal gas emission, blood hematology, and antioxidative indicators in growing pigs. A total of 200 crossbred pigs [(Landrace × Yorkshire) × Duroc] with an initial body weight of 24.52 ± 1.99 kg were used in a 42-day experiment with a completely randomized block design. Pigs were randomly divided into 4 treatment groups with 10 replicate pens per treatment and 5 animals per pen (2 barrows and 3 gilts). There were four diet conditions: 1) CON, basal diet; 2) TRT1, basal diet + 0.1% apramycin; 3) TRT2, basal diet + 0.1% SB extract; 4) TRT3, basal diet + 0.1% enzymatic bio-conversion of SB extract. The pen was taken as the experimental unit. Tukey’s multiple range test was used for evaluation of differences among the treatments. Compared with the CON group, TRT1 or TRT3 groups had higher final body weight (BW) (P = 0.074) and average daily gain (ADG) (P = 0.075), and lower feed conversion ratio (FCR) (P = 0.054). The apparent total tract digestibility (ATTD) of dry matter (DM) (P = 0.095) in TRT1 group was higher than that in CON group. Serum glutathione peroxidase (GPX) (P = 0.047) and glutathione (GSH) (P = 0.074) concentrations in TRT3 group were higher than those in CON or TRT1 groups. However, there were no significant differences in fecal microbiota, fecal gas emission, and blood hematology among all dietary groups. A positive correlation between apramycin supplementation in the diet and ADG and the ATTD of DM were observed. A positive correlation between enzymatic bio-conversion of SB extract supplementation in the diet and ADG and the concentration of GPX and GSH in serum were also observed.

Dietary Treatments

A ten-week experimental trial was carried out to determine the effect of - dietary inclusion of Achyranthes japonica extract (AJE) on finishing pigs overall performance. A total of 150 finishing pigs with initial body weight (BW) of 54.17 ± 2.27 kg were randomly allocated to 5 dietary treatments. The dietary treatments were CON (Basal diet), TRT1 (Basal diet + 0.025% AJE), TRT2 (Basal diet + 0.05% AJE), TRT3 (Basal diet + 0.1% AJE), TRT4 (Basal diet + 0.2% AJE). Dietary AJE supplementation linearly increased BW, average daily gain (ADG), and gain to feed ratio (G:F) during week 5. At week 10 and overall experiment, there was tendency for linear increase in BW, ADG and ADFI. Dietary supplementation of AJE failed to show significant effects on nutrient digestibility, fecal microbiota, meat quality, and fecal gas emission. The dietary supplementation of AJE showed a linear increase in the backfat thickness at week 10 and there was no significant difference observed on the lean meat percentage. In summary, Achyranthes japonica extract supplementation diet had a beneficial effect on the growth performance and backfat thickness and also no effects on nutrient digestibility and fecal microbiota of the finishing pigs.

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.
