Evaluation of Dietary Bovine Milk Fat Globule Membrane Supplementation on Growth, Serum Cholesterol and Lipoproteins, and Neurodevelopment in the Young Pig.

ABSTRACT: Introduction: Milk fat globule membrane (MFGM) is a protein- and phospholipid-rich membrane that surrounds the lipid droplet in milk. We have previously reported that a diet composed of a combination of prebiotics, bovine MFGM (bMFGM), and lactoferrin (bLf) supported brain development in young pigs. Due to the growing interest of its potential benefits in neurodevelopment, the present study focused on the effects of dietary bMFGM alone using the pig as a translational model. Methods: Male pigs were provided ad libitum access to milk replacer with added whey protein-lipid concentrate (source of bMFGM) at 0 (CONT), 2.5 (MFGM-2.5), or 5 (MFGM-5.0) g/L from postnatal day (PND) 2 to 31. Blood was collected from pigs at PND 15 and 31, and pigs underwent behavioral testing using the novel object recognition task starting at PND 25. At PND 31, magnetic resonance imaging was conducted and animals were subsequently euthanized for tissue collection. Results: No group differences in body weight gain or milk intake were observed. At PND 31, few group differences were detected in absolute and relative brain volumes, brain water diffusivity outcomes, or behavioral parameters using the novel object recognition task. Serum lipoprotein was higher in pigs receiving diets with added dietary bMFGM compared with the CONT group. Serum cholesterol and high-density lipoprotein significantly higher (all P < 0.05) in the MFGM-2.5 compared with the CONT group. However, cholesterol concentrations within the brain prefrontal cortex and hippocampus did not differ among dietary groups. Conclusion: In this pig model, dietary supplementation with bMFGM was well-tolerated and supported growth and dietary intake similar to the control formula. Added dietary bMFGM was associated with increased serum lipoprotein, but no group differences in early brain cholesterol concentrations, macrostructure, microstructure, or recognition memory pigs at 31 days of age. Further examination of longitudinal brain development and myelination in the pig, particularly at later ages/maturation, is warranted.

Project description:Milk fat globule membrane (MFGM), mainly comprising protein and fat, has been reported to have multiple biological functions for relieving intestinal inflammation and enhancing growth performance. We hypothesized that MFGM supplementation into sows' diet during late gestation can have a positive impact on the intestinal microecology of sows and their piglets, as well as on the growth of neonates. Therefore, the present study was conducted to investigate such effects and their potential mechanisms. Twenty-two pregnant sows were selected and randomly divided into the CON group (basal diet) and MFGM group (basal diet supplemented with 9.9 g per day MFGM). The feeding period began from d 85 of gestation and until farrowing. The concentrations of albumin (ALB), low-density lipoprotein cholesterol (LDL-C), and non-esterified fatty acids (NEFA) in plasma and short-chain fatty acids (SCFAs) in feces of sows from the MFGM group were determined. The concentrations of growth hormone (GH), immunoglobulin A (IgA), glucose (GLU), and NEFA in the umbilical cord blood in the MFGM group were significantly higher than those in the CON group. Piglets from the MFGM group showed improved growth performance, increased villus height in the jejunum, decreased crypt depth in the duodenum and jejunum, upregulated mRNA expressions of tight junctions (namely, Occludin; Claudin-1, Claudin-2, and Claudin-4; zonulin-1 (ZO-1)); mucins such as Mucin 2, Mucin 4, Mucin 13, and Mucin 20; and immune-related genes, such as tumor necrosis factor-α (TNF-α), interferon-γ (INF-γ), interleukin-22 (IL-22), toll-like receptor 2 (TLR2), and toll-like receptor 4 (TLR4). In addition, the abundance of Prevotella in the feces of sows at farrowing and the abundance of Christensenellaceae_R-7_group in the feces of 21 day-old piglets from the MFGM group were significantly higher. Further correlation analysis revealed that the Christensenellaceae_R-7_group was positively correlated with the relative mRNA expressions of Occludin, Claudin-1, Claudin-2, Claudin-4, Mucin 13, TLR2, and TLR4. In conclusion, MFGM supplementation during late gestation improved the physiological status of sows by improving their plasma parameters and intestinal microecology. The improved provision of nutrients through the umbilical cord blood and optimized microbiota colonization in neonatal piglets were beneficial to the intestinal morphological structure and barrier functions, consequently improving the growth performance of neonates during lactation. These findings provide insights into the future applications of MFGM with regard to maternal-fetal nutrition and a new option for nutritional intervention of neonates through maternal dietary manipulation.
