A 6 wk trial was conducted to evaluate the effects of nucleotide supplementation in improving performance, nutrient digestibility, and immune blood profiles so as to reduce foot-and-mouth disease (FMD) vaccine stress in growing pigs. A total of 120 growing pigs [(Yorkshire × Landrace) × Duroc] with an average body weight (BW) of 25.76 ± 1.83 kg were used. Pigs were allocated to one of three treatments (eight pens per treatment; three barrows and two gilts per pen) based on BW and sex. Pigs were injected with FMD vaccine at 84 d of age (2 wk after experiment started). Dietary treatments consisted of (1) CON: corn–soybean-meal-based diet, (2) NUC1: CON + 0.5% nucleotide, and (3) NUC2: CON + 1.0% nucleotide. In the current study, the growth performance of gain:feed ratio (G:F), the apparent total tract digestibility of dry matter and nitrogen was linearly (P < 0.05) increased with the increasing level of nucleotide. After injection, the concentration of cortisol and epinephrine was decreased (P < 0.05) linearly in nucleotide treatments. In conclusion, nucleotide supplementation to FMD vaccinated pigs showed positive effects on improving performance, immune system health, and reducing vaccine stress in growing 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.

The present study was conducted to evaluate the effects of replacing corn with brown rice on growth performance, nutrient digestibility, carcass characteristics, and gut microbiota of growing and finishing pigs. A total of 100 growing pigs (23.80 ± 2.96 kg BW; 10 weeks of age) were randomly allotted to 4 dietary treatments (5 pigs/pen; 5 replicates/treatment) in a randomized complete block design (block = BW) as follows: corn-soybean meal basal diet (CON) and replacing corn with 50% (GBR50), 75% (GBR75), and 100% (GBR100) of ground brown rice. Each trial phase was for 6 weeks. During the growing period, there were no differences on growth performance and nutrient digestibility among dietary treatments. Similarly, no differences were found on growth performance, nutrient digestibility, and carcass characteristics of pigs during the finishing period among dietary treatments. As a result of the beta diversity analysis, microbial populations were not clustered between CON and GBR100 during the growing phase, but clustered into two distinct groups of CON and GBR100 during the finishing phase. In conclusion, brown rice can be added to the diets of growing-finishing pigs by replacing corn up to 100% without negatively affecting growth performance of the pigs; additionally, this may have an effect on changes in pig intestinal microbiota if continued for a long time.

Abstract As an alternative to antimicrobial growth promoters, fermented feed (FF) has been continuously developed for two decades; however, its effects on feed, performance, digestibility, and meat quality of pigs have yet to be systematically and comprehensively evaluated. This study aimed to (i) quantitatively evaluate the effects of fermentation on nutritional components of feed stuffs; (ii) quantitatively evaluate the effects of FF on pig growth performance, digestibility, and meat quality; and (iii) explore the dose–effect relationship. From PubMed and Web of Science (searched range from January 1, 2000 to April 4, 2019), we collected 3,271 articles, of which 30 articles (3,562 pigs) were included in our meta-analysis. Our analysis revealed that fermentation significantly increased the CP content in feed (P &lt; 0.05). For weaned piglets and growing pigs, FF significantly improved ADG, G:F, DM digestibility, N digestibility, and energy digestibility (P &lt; 0.05). However, compared with the basal diet, FF had no significant effects on growth performance and nutrient digestibility in finishing pigs (P &gt; 0.05). In the subgroup analyses, fermented ingredients increased the growth performance of weaned piglets and growing pigs, and fermented additives promoted the growth of pigs at all stages. The dose–effect analysis confirmed that the optimal doses of fermented ingredients and additives were 8% and 0.15%, respectively. Furthermore, FF had beneficial impacts on meat quality through increased lightness, redness, marbling and flavor and reduced drip loss (P &lt; 0.05). In conclusions, FF improved growth performance and meat quality primarily due to its positive effects on nutritive value and utilization.

The aim of this study was to assess the effects of dietary probiotic enhanced liquid acidifier combined with mannan-rich fraction on growth performance, nutrients digestibility in growing pigs. Thirty [(Duroc×Yorkshire)×Landrace] pigs with the average initial BW of 36.75±1.57 kg were allocated into three treatments by a randomized complete block design. There were five pens per treatment with six pigs per pen. Dietary treatments include: 1) CON (basal diet); 2) T1 (basal diet+probiotic 0.1%) and 3) T2 (basal diet+probiotic+mannan rich fraction 0.2%). the data were analyzed as a randomized complete block design using of SAS University Version 4.0. The model included the effects of block (replication) and treatment. Pen served as the experimental unit. During the entire experimental period of 6 weeks, results showed that addition of complex probiotic at the level of 0.2% to diet increased ADG significantly (p<0.05). Also, digestibility of DM and N tended to increase. To sum up, results in this experiment indicated that dietary [(probiotik×acidifier)×mannan-rich-fraction]  supplementation had a positive effect on growing pigs performance and nutrient digestibility
