Intestinal microbiota is necessary for the guarantee of intestinal mucosal barrier. However, the detailed effect of probiotics on porcine intestinal development, especially in the early life, is still unclear. In this study, we treated 3-day-old newborn piglets with () D8 and observed its beneficial effect on piglets. The body weights, villus height, and crypt depth of jejunum were all significantly increased after treatment in piglets. also significantly increased the proliferation index of PCNA cells in the crypt, as well as c-Myc and Tcf4 expressions. Furthermore, also enhanced intestinal mucosal barrier with the increase of goblet cells and antimicrobial peptides (AMPs) expressions of Muc2, Lyz1, and pBD1. The well development of Peyer's patches and increased number of CD3 T cells, combined with increased expression of IL-4 and IFN-γ, also demonstrated the immune stimulation effect of D8. This study demonstrated that promotes the development of intestine mucosal system and maintains intestinal mucosal barrier in newborn piglets.

Glyphosate-based herbicide (GBH), a feed contaminant, has been proven to impair the growth and development of humans and animals. Previous research has revealed that maternal toxin exposure during pregnancy could cause permanent fetal changes by epigenetic modulation. However, there was insufficient evidence of the involvement of DNA methylation in maternal GBH exposure-induced intestinal health of offspring.

Acute kidney injury (AKI) has been reported to occur in 30-70% of asphyxiated neonates. Hydrogen (H) gas became a major research focus in neonatal medicine after the identification of its robust antioxidative properties. However, the ability of H gas to ameliorate AKI is unknown.

Despite the WHO recommendations in favor of breastfeeding, most infants receive infant formulas (IFs), which are complex matrices involving numerous ingredients and processing steps. Our aim was to understand the impact of the quality of the protein ingredient in IFs on gut microbiota and physiology, blood metabolites and brain gene expression. Three IFs were produced using whey proteins (WPs) from cheese whey (IF-A) or ideal whey (IFs-C and -D) and caseins, either in a micellar form (IFs-A and -C) or partly in a non-micellar form (IF-D).

Background: Epinephrine is currently the only recommended cardio-resuscitative medication for use in neonatal cardiopulmonary resuscitation (CPR), as per consensus of science and treatment recommendations. An alternative medication, vasopressin, may be beneficial, however there is limited data regarding its effect on cardiac and brain tissue following recovery from neonatal CPR.
Aim: To compare the effects of vasopressin and epinephrine during resuscitation of asphyxiated post-transitional piglets on cardiac and brain tissue injury.

Article Synopsis
- PDCoV is increasingly affecting newborn piglets, causing diarrhea, and poses significant challenges to the pig industry due to its potential for cross-species transmission.
- A new PDCoV strain was isolated from piglets in China, showing high genetic similarity to other strains and notable amino acid mutations in its S protein that alter its structure and function.
- The study confirmed that this strain damages the intestinal barrier of piglets, leads to clinical symptoms like diarrhea, and lays the groundwork for future vaccine and diagnostic development to combat piglet diarrhea.
