Special Issue Information

Dear Colleagues,

As the main site of nutrients digestion and absorption and an important defense line against the invasion of bacteria and endotoxins into the intestinal lumen, the intestinal tract is an important organ in response to stress in piglets. In modern intensive large-scale swine production, piglets may encounter various external stress challenges, which include social factors like stocking density, feed-related factors such as mycotoxin contamination, environmental factors like weaning stress, heat stress, pathogenic factors including Escherichia coli infections, and others. Those challenges usually affect the intestinal health of piglets, eventually, lead to economic losses. Many nutritional strategies have been applied to improve intestinal health which could increase the survival rate and growth performance in piglets. Those strategies include but not limited to supplementation of functional feed additives, such as plant extract and essential oil, trace elements, antimicrobial peptides, short-chain fatty acids and functional amino acids and derivatives. This research topic will primarily focus on the innovative nutritional strategies to improve intestinal health in piglets. Additionally, researchers are encouraged to investigate the underlying mechanisms.

Damp-heat diarrhea (DHD) in piglets presents as diarrhea and intestinal bleeding, significantly affecting both piglet health and the pig industry. Pulsatilla powder (PP), a herbal formulation composed of Pulsatilla, Rhizoma Coptidis, Phellodendron Bark, and Fraxini Cortex, has proven to be an effective treatment for DHD. Although the pentose phosphate pathway (PPP) has been associated with its therapeutic effects, the exact mechanism of action remains unclear. In this study, the DHD model in piglets was established to evaluate clinical symptoms, organ index, serum index, histological changes, colonic metabolites, and molecular mechanisms using techniques such as QPCR, ELISA, WB and metabolomics. PP improved intestinal health by restoring spleen and lung index, increasing LDL-C and HDL-C levels (HDL-C: p < 0.05), decreasing mRNA expression levels of IFN-γ and TNF-α mRNA (p < 0.01), and increasing MUC1 and MUC2 expression. Metabolomics analysis has identified 44 pathways, including pentose phosphate and glutathione pathways, and 132 differential metabolites have involved in DHD treatment. PP significantly reduced G6PD (p < 0.01), inhibited the pentose phosphate pathway, reduced NOX production (p < 0.01), and suppressed ROS production (p < 0.01). These effects alleviated oxidative stress and intestinal damage, demonstrating PP’s effectiveness in treating DHD by targeting critical enzymes and ROS levels. Full article

The genus Mallotus oblongifolius (MO), a member of the Euphorbia family, exhibits a predominant distribution in Hainan Island and has been proven to possess diverse medicinal attributes. Research indicates that ultramicro-grinding fully exposes the active ingredients of Mallotus oblongifolius, enhancing bioavailability and efficacy, compared to before. Our study investigates the effects of ultrafine powder of Mallotus oblongifolius (MOUP) on Hainan pigs. A total of sixty-four healthy castrated pigs (ternary hybrid pigs, Duroc × Duroc × Tunchang) with comparable initial body weight (BW, 68.06 ± 1.03 kg, 150 days old) were allocated randomly into four groups: the control group (CONT), the antibiotic group (ANTI), the 0.1% MOUP group (PT1), and the 0.5% MOUP group (PT2). There were four replicate pens per treatment with four pigs per pen. The pre-test lasted for 7 days and the formal test lasted for 70 days. The CONT group was fed the basal diet, the ANTI group was fed the basal diet supplemented with 300 mg/kg colistin sulfate, the PT1 group was fed the basal diet supplemented with 0.1% MOUP, and the PT2 group was fed the basal diet supplemented with 0.5% MOUP. The findings of our study indicate that the inclusion of colistin sulfate and MOUP in the diet did not have any significant impact on the production performance or carcass indicators of Hainan pigs compared to the CONT group. However, it is noteworthy that the addition of MOUP to the diet resulted in a significant improvement in the lightness, tenderness, muscle fiber morphology, amino acid composition, and antioxidant activity of the longissimus dorsi muscle, particularly in the PT2 group, compared to the CONT group. In conclusion, the present study has demonstrated that the inclusion of MOUP in the dietary regimen yields enhancements in the meat quality of Hainan pigs, particularly when supplemented at a concentration of 0.5%.
