Abstract
This review examines the challenges faced by the pig industry, with a specific focus on improving the health and growth of weaned pigs. It emphasizes the immediate necessity of investigating alternative approaches to managing pig nutrition and health due to restrictions on the use of antibiotics and the prohibition of zinc oxide in weaned pig diets. The weaning phase is identified as a critical stage in piglet development, characterized by stressors that affect their gastrointestinal health, immune responses, and overall physiology. The primary challenge during weaning arises from transitioning piglets from a digestible milk-based diet to a less digestible cereal-based feed, causing nutritional stress. This manifests as reduced feed intake, leading to gastrointestinal disturbances, intestinal inflammation, and adverse effects on intestinal structure and microbiota. To address these challenges and optimize piglet development, various nutritional strategies have been explored. Notably, glucans, particularly β-glucans from fungi, cereals, algae, and yeast, show promise in alleviating weaning-related issues. Furthermore, it is important to highlight the critical roles played by Vitamin D and selenium in piglet nutrition. These essential nutrients can be sourced naturally from enriched mushrooms that are specifically enriched with Vitamin D and selenium, providing a sustainable dietary option. In conclusion, effective nutritional strategies, including glucans, Vitamin D, selenium, and enriched mushrooms, are beneficial for addressing weaning-related challenges.

Capsaicin and 1,25-Dihydroxyvitamin D 3 Glycoside: Effects on the Reproductive Performance of Hyper-Prolific Sows. Animals (Basel) 2023; 13:2794. [PMID: 37685058 PMCID: PMC10486751 DOI: 10.3390/ani13172794] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2023] [Revised: 08/26/2023] [Accepted: 08/27/2023] [Indexed: 09/10/2023] Open
Abstract
This study evaluated the effect of a natural source of vitamin D3 [1,25-(OH)2D3] and capsaicin (CAP) in the dietary supplementation of sows in the final phase (85-114 days) of gestation (Gest) and lactation (Lact) on the reproductive performance of the sows and health of piglets through two experiments (Exp I and II). In Exp I, 120 sows were subjected to four treatments: T1-control (without [1,25-(OH)2D3] and supplemental CAP); T2-3.5 µg 1,25-(OH)2D3/Gest/day and 7.0 µg Vit 1,25-(OH)2D3/Lact/day; T3-7.0 µg CAP/Gest/day and 14.0 µg CAP/Lact/day; T4-1.75 µg Vit 1,25-(OH)2D3 + 3.5 µg CAP/Gest/day and 3.5 µg 1,25-(OH)2D3 + 7.0 µg CAP/Lact/day. In Exp II, 200 sows were randomly blocked, factorial 2 × 2 (without or with Vit 1,25-(OH)2D3 and without or with CAP): T1-control (without Vit 1,25-(OH)2D3 and CAP); T2-3.5 µg Vit 1,25-(OH)2D3/Gest/day and 7.0 µg Vit 1,25-(OH)2D3/Lact/day; T3-7.0 µg CAP/Gest/day and 14.0 µg CAP/Lact/day; T4-3.5 µg Vit 1,25-(OH)2D3 + 7 µg CAP/Gest/day; and 7.0 µg Vit 1,25-(OH)2D3 + 14.0 µg CAP/Lact/day. The duration of delivery (3:48 vs. 4:57 h) and the percentage of stillbirths (5.37% vs. 7.61%) were improved (p < 0.05) in the group that received Vit 1,25-(OH)2D3 (Exp II) compared to the control group. Moreover, the dystocia rate decreased (p < 0.05) in Exp II, which received Vit 1,25-(OH)2D3 (4.21 vs. 27.63%), and in Exp I, which received the combination of Vit 1,25-(OH)2D3 + CAP (12 vs. 40%) compared to the respective control groups. Colostrum production was greater (p < 0.05) in sows that received Vit 1,25-(OH)2D3 supplementation compared to the control group, consequently resulting in higher colostrum intake (p < 0.05) of the piglets (330 vs. 258 g/piglet). The additives reduced the incidence of diarrhea (p < 0.05) in piglets (Exp I and II). Thus, the use of additives improved the reproductive performance of sows and contributed to litter growth.

Int J Mol Sci 2022; 23:ijms231810603. [PMID: 36142545 PMCID: PMC9504568 DOI: 10.3390/ijms231810603] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 09/06/2022] [Accepted: 09/08/2022] [Indexed: 11/16/2022] Open
Abstract
Porcine epidemic diarrhea virus (PEDV) infection causes watery diarrhea and vomiting in piglets. The pathogenesis of PEDV infection is related to intestinal inflammation. It is known that 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) has potent anti-inflammatory activity, but it is unknown whether 1,25(OH)2D3 can inhibit the PEDV-induced inflammatory response and the underlying mechanism. We used transcriptome analysis, gene and protein expression, RNA interference and overexpression, and other techniques to study the anti-inflammatory effects of 1,25(OH)2D3 on PEDV infection in IPEC-J2 cells. The results showed that interleukin 19 (IL-19) and C-C motif chemokine ligand 20 (CCL20) gene expression were enhanced with the increase in PEDV infection time in IPEC-J2 cells. Interestingly, 1,25(OH)2D3 supplementation obviously inhibited IL-19 and CCL20 expression induced by PEDV. Meanwhile, we also found that 1,25(OH)2D3 reduced p-NF-κB, p-STAT1, and p-STAT3 protein levels induced by PEDV at 24 h post-infection. IκBα and SOCS3, NF-κB, and STAT inhibitor respectively, were increased by 1,25(OH)2D3 supplementation upon PEDV infection. In addition, 1,25(OH)2D3 supplementation inhibited ISG15 and MxA expression induced by PEDV. Although 1,25(OH)2D3 suppressed the JAK/STAT signal pathway and antiviral gene expression, it had no significant effects on PEDV replication and IFN-α-induced antiviral effects. In addition, when the vitamin D receptor (VDR) was silenced by siRNA, the anti-inflammatory effect of 1,25(OH)2D3 was inhibited. Meanwhile, the overexpression of VDR significantly downregulated IL-19 and CCL20 expression induced by PEDV infection. Together, our results provide powerful evidence that 1,25(OH)2D3 could alleviate PEDV-induced inflammation by regulating the NF-κB and JAK/STAT signaling pathways through VDR. These results suggest that vitamin D could contribute to inhibiting intestinal inflammation and alleviating intestinal damage in PEDV-infected piglets, which offers new approaches for the development of nutritional strategies to prevent PEDV infection in piglets.

J Anim Physiol Anim Nutr (Berl) 2022; 106:1288-1305. [PMID: 36045590 DOI: 10.1111/jpn.13768] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 07/31/2022] [Accepted: 08/11/2022] [Indexed: 12/01/2022]
Abstract
25-hydroxycholecalciferol (25-OHD3 ) formed via hepatic hydroxylation from vitamin D, cholecalciferol, represents the precursor of the biologically active vitamin D hormone, 1,25-dihydroxyvitamin D. Due to a higher absorption rate and the omission of one hydroxylation, dietary supplementation of 25-OHD3 instead of vitamin D3 is considered to be more efficient as plasma concentrations of 25-OHD3 are increased more pronounced. The present review summarises studies investigating potential beneficial effects on mineral homeostasis, bone metabolism, health status and performance in sows, piglets and fattening pigs. Results are inconsistent. While most studies could not demonstrate any or only a slight impact of partial or total replacement of vitamin D3 by 25-OHD3 , some experiments indicated that 25-OHD3 might alter physiological processes when animals are challenged, for example, by a restricted mineral supply.

Abstract
Vitamin D signaling is important for intestinal homeostasis. An increase in vitamin D receptors in immune cells can modulate cell phenotype and cytokine secretion. Cytokines regulate both pro- (interleukin 17; IL-17) and anti-inflammatory (IL-10) responses triggered by external stimuli. Inflammation in intestinal tissues can disrupt the structure and the remodeling of epithelial tight junction complexes, thus, compromising the protective barrier. The objective of the study was to determine the impact of dietary supplementation with 25-hydroxycholecalciferol (25OHD3), a hydroxylated metabolite of vitamin D, on intestinal cytokine abundance and epithelial barrier integrity over time in broilers. A randomized complete block design experiment was conducted to evaluate the effect of dietary 25OHD3 inclusion on relative protein expression of the cytokines, IL-17 and IL-10, and tight junction proteins, Zona Occludens 1 (ZO-1), and Claudin-1 (CLD-1), in broiler chicken duodenum and ileum from 3 to 21 days post-hatch. On day 0, male chicks (n = 168) were randomly assigned to raised floor pens. Experimental corn–soybean meal-based treatments were as follows: (1) a common starter diet containing 5,000 IU of D3 per kg of feed (VITD3) and (2) a common starter diet containing 2,240 IU of D3 + 2,760 IU of 25OHD3 per kg of feed (25OHD3) fed from days 0 to 21. On days 3, 6, 9, 12, 15, 18, and 21, 12 birds per treatment were euthanized to collect tissue samples for quantitative, multiplex, and fluorescent Western blot analysis. Target proteins were quantified using Image Quant TL 8.1 and expressed relative to total protein. Feeding 25OHD3 post-hatch decreased ileal IL-10 (anti-inflammatory) protein expression in 21-day-old broilers compared with VITD3 only (P = 0.0190). Broilers fed only VITD3 post-hatch had greater IL-17 (pro-inflammatory) protein expression in the ileum at 18 and 21 days-of-age (P = 0.0412) than those that fed 25OHD3. Dietary inclusion of 25OHD3 lowered the abundance of key inflammatory cytokines in the ileum of young broilers.

Abstract
Porcine epidemic diarrhea virus (PEDV) infection causes heavy economic losses in the pig industry. Currently, the lack of effective treatments prompts new antiviral researches. We have shown that 25-hydroxyvitamin D3 supplementation alleviated PEDV infection in weaned pigs before. However, it is not clear whether vitamin D inhibits PEDV replication. In this study, 1,25-dihydroxyvitamin D3 (1,25(OH)2D3) inhibited PEDV induced mitochondria damage and cell apoptosis. In addition, 1,25(OH)2D3 treatment decreased PEDV nucleocapsid gene and protein levels in IPEC-J2 cells. Transcriptomic data showed that PEDV infection altered the expression of 5316 genes (2498 up, 2818 down) in IPEC-J2 cells. The differentially expressed genes were mainly involved in cell cycle process, ribonucleoprotein complex biogenesis, mitotic nuclear division, and other biological processes. Then we examined the effects of PEDV infection on cell cycle progression in IPEC-J2 cells, and the results showed that PEDV induced G0/G1 phase arrest. G0/G1-phase arrest was also conducive to PEDV replication. However, 1,25(OH)2D3 treatment decreased G0/G1 phase percentage induced by PEDV. Cyclin D and cyclin E mRNA expression were also increased by 1,25(OH)2D3 supplementation upon PEDV infection. Moreover, the regulation of 1,25(OH)2D3 on cell cycle progression was abrogated by ERK1/2 inhibitor, as well as the mRNA expression of cyclin D. The inhibition of 1,25(OH)2D3 on PEDV replication was also eliminated by ERK1/2 inhibitor. Taken together, these results demonstrated that 1,25(OH)2D3 supplementation inhibited PEDV replication, and the anti-virus effect of 1,25(OH)2D3 was mediated in part by regulating cell cycle progression through ERK1/2 signaling pathway.

Abstract
This study was conducted to test the effects of maternal 25-hydroxycholecalciferol (25OHD3) supplementation on serum parameters, intestinal morphology and microbiota in suckling piglets. The experiment started on day 107 of gestation and lasted until piglets were weaned on day 21 of lactation. Thirty-two sows were allocated randomly to two treatments (ND diet, basal diet with 2000 IU/kg of vitamin D3; 25-D diet, basal diet with 50 μg/kg 25OHD3). Results showed that maternal 25-D treatment increased (p < 0.05) serum 25OHD3 concentration in the umbilical cords, which led to higher (p < 0.05) serum 25OHD3 concentration of suckling piglets from 25-D sows. The GSH-Px activity in colostrum was higher (p < 0.05), as well as SOD and GSH-Px activities in milk, were higher (p < 0.05) in 25-D sows than ND sows. Compared with piglets suckling ND sows, piglets suckling 25-D sows had higher (p < 0.05) serum SOD activity on day 7, 14 and 21 of lactation. On day 21 of lactation, piglets form 25-D sows had greater (p < 0.05) serum levels of GH and IGF-I and lower (p < 0.05) serum DAO activity than those from ND sows. Piglets from 25-D sows had higher (p < 0.05) jejunal villus height than those from ND sows. Feeding 25OHD3 to sows tended to increase (p < 0.10) the species richness in the colonic digesta of suckling piglets, as reflected by the α-diversity index of Chao-1. In the caecal digesta, the α-diversity for bacterial community analysis of Simpson and Shannon was lower (p < 0.05) in 25-D piglets than ND piglets. The relative abundances of colonic Alloprevotella and caecal Lactobacillus were significantly higher, while the population of caecal [Eubacterium]_coprostanoligenes_group was lower (p < 0.05) in 25-D piglets than ND piglets. In conclusion, maternal 25OHD3 supplementation partly improved antioxidant status in sows and suckling piglets and altered gut microbiota in the hindgut of piglets.

[PMID: 32235600 PMCID: PMC7230640 DOI: 10.3390/nu12040962] [Citation(s) in RCA: 24] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2020] [Revised: 03/23/2020] [Accepted: 03/26/2020] [Indexed: 12/11/2022] Open
Abstract
Vitamin D (VD) plays an essential role in mineral homeostasis and bone remodeling. A number of different VD-related genes (VDRG) are required for the metabolic activation of VD and the subsequent induction of its target genes. They include a set of genes that encode for VD-binding protein, metabolic enzymes, and the VD receptor. In addition to its well-characterized skeletal function, the immunoregulatory activities of VD and the related polymorphisms of VDRG have been reported and linked to its therapeutic and preventive actions for the control of several viral diseases. However, in regards to their roles in the progression of viral diseases, inconsistent and, in some cases, contradictory results also exist. To resolve this discrepancy, I conducted an extensive literature search by using relevant keywords on the PubMed website. Based on the volume of hit papers related to a certain viral infection, I summarized and compared the effects of VD and VDRG polymorphism on the infection, pathogenesis, and treatment outcomes of clinically important viral diseases. They include viral hepatitis, respiratory viral infections, acquired immunodeficiency syndrome (AIDS), and other viral diseases, which are caused by herpesviruses, dengue virus, rotavirus, and human papillomavirus. This review will provide the most current information on the nutritional and clinical utilization of VD and VDRG in the management of the key viral diseases. This information should be valuable not only to nutritionists but also to clinicians who wish to provide evidence-based recommendations on the use of VD to virally infected patients.

[PMID: 32085410 PMCID: PMC7168134 DOI: 10.3390/pathogens9020130] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2019] [Revised: 02/13/2020] [Accepted: 02/14/2020] [Indexed: 02/08/2023] Open
Abstract
Porcine epidemic diarrhea virus (PEDV) is a highly virulent re-emerging enteric coronavirus that causes acute diarrhea, dehydration, and up to 100% mortality in neonatal suckling piglets. Despite this, a safe and effective PEDV vaccine against highly virulent strains is unavailable, making PEDV prevention and control challenging. Lactogenic immunity induced via the gut-mammary gland-secretory IgA (sIgA) axis, remains the most promising and effective way to protect suckling piglets from PEDV. Therefore, a successful PEDV vaccine must induce protective maternal IgA antibodies that passively transfer into colostrum and milk. Identifying variables that influence lymphocyte migration and IgA secretion during gestation and lactation is imperative for designing maternal immunization strategies that generate the highest amount of lactogenic immune protection against PEDV in suckling piglets. Because pregnancy-associated immune alterations influence viral pathogenesis and adaptive immune responses in many different species, a better understanding of host immune responses to PEDV in pregnant swine may translate into improved maternal immunization strategies against enteric pathogens for multiple species. In this review, we discuss the role of host factors during pregnancy on antiviral immunity and their implications for generating protective lactogenic immunity in suckling neonates.

McCue M, Reichert JL, Crenshaw TD. Impact of dietary vitamin D3 supplements in nursery diets on subsequent growth and bone responses of pigs during an immune challenge. J Anim Sci 2019; 97:4895-4903. [PMID: 31701141 PMCID: PMC6915220 DOI: 10.1093/jas/skz347] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2019] [Accepted: 11/06/2019] [Indexed: 02/06/2023] Open
Abstract
Limited evidence is available to validate beneficial responses from extra nutrient supplements for mediation of growth suppression that results from immune challenges. Extrarenal roles of vitamin D metabolites in immune function implicate vitamin D3 supplements as a nutrient for potential beneficial effects. The current objective was to assess growth and bone ash responses to dietary vitamin D3 (D) supplements for growing pigs undergoing an immune challenge. At weaning, 216 crossbred pigs (4 pigs/pen, 6 pens/treatment) were randomly allotted within sex and weight blocks to 1 of the 9 treatments. Treatments included D supplements (0, 100, or 800 IU/kg) in a factorial arrangement with 3 vaccine (V) protocols; no injection (0 × V), a single 2 mL injection of a Lawsonia intracellularis vaccine at day 14 (1 × V), or 2 mL injections of the same vaccine at days 0 and 7 (2 × V). An adjustment diet with no supplemental D was fed for 1 wk, then assigned D diets for 2 wk (P2). After P2, all pigs were phase-fed standard diets (D = 280 IU/kg) to assess subsequent growth to 115 kg. No differences due to D supplements or vaccination protocol were detected in ADG (0.233 ± 0.021 kg/d) or GF (0.642 ± 0.028 kg/d) over the 21-d nursery trial; however, ADFI was lower (P < 0.10) in pigs fed D levels of 0 vs. 100 and 800 (0.340 vs. 0.375, 0.372 ± 0.027 kg/d). Bone mineral content (g) from whole-body dual energy X-ray absorptiometry scans at 9 wk (n = 4 pigs/treatment) was lower in pigs fed 0 vs. 100 and 800 IU of D (287 vs. 325, 323 ± 34.1 g/pig). Growth from nursery to 115 kg was lower (P < 0.01) in pigs fed D levels of 0 vs.100 and 800 (0.828 vs. 0.876, 0.889 ± 0.021 kg/d). At market, approximately two-thirds of pigs showed positive L. intracellularis serology titers regardless of treatment. Limited evidence for D-mediation of an immune challenge using the vaccination protocols may be a consequence of limited vaccine effects on growth in the nursery and seroconversion of most pigs to L. intracellularis by market.
