This study aimed to determine the regulatory mechanism of dietary zinc lactate (ZL) supplementation on intestinal oxidative stress damage in a paraquat (PQ)-induced piglet model. Twenty-eight piglets (mean body weight 9.51±0.23 kg) weaned at 28 d of age were randomly divided into control, ZL, PQ, and ZL+PQ groups (n=7 in each group). The ZL-supplemented diet had little effect on growth performance under normal physiological conditions. However, under PQ challenge, ZL supplementation significantly improved average daily gain (P<0.05) and reduced the frequency of diarrhea. ZL improved intestinal morphology and ultrastructure by significantly increasing the expression level of the jejunal tight junction protein, zonula occludens-1(ZO-1) (P<0.05), and intestinal zinc transport and absorption in PQ-induced piglets, which reduced intestinal permeability. ZL supplementation also enhanced the expression of antioxidant and antiinflammatory factor-related genes and decreased inflammatory cytokine expression and secretion in PQinduced piglets. Furthermore, ZL treatment significantly inhibited the activation of constitutive androstane receptor (CAR) signaling (P<0.01) in PQ-induced piglets and altered the structure of the gut microbiota, especially by significantly increasing the abundance of beneficial gut microbes, including UCG＿002, Ruminococcus, Rikenellaceae＿RC9＿gut＿group, Christensenellaceae＿R＿7＿group, Treponema, unclassified＿Christensenellaceae, and unclassified＿Erysipelotrichaceae (P <0.05). These data reveal that pre-administration of ZL to piglets can suppress intestinal oxidative stress by improving antioxidant and anti-inflammatory capacity and regulating the crosstalk between CAR signaling and gut microbiota.

Priming effect（PE） on soil organic carbon（SOC） decomposition caused by the addition of organic carbon（C） is an important ecological process in regulating soil C cycle. Additionally, most priming studies are confined to laboratory trials, while the assessment of soil PE under field conditions with variable weather conditions is scarce. This study assessed the direct effects of glucose addition and in-situ warming on the extent of PE under field conditions in a temperate forest. We evaluated soil PE using13C-glucose labelling, a simple and novel technique, based on the Keeling plot method. Glucose addition significantly enhanced native SOC decomposition and induced strong PE. However, the effect of in-situ warming on the extent of PE was not significant. This study confirms the importance of PE in regulating SOC turnover under field conditions.
