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.

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.

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.
