Comparing the composition and trend of fatty acid in human milk with bovine milk and infant formula in northeast region of China

1. Very little is known about the biological availability of manganese from human milk and other infant milk diets. To determine the relative Mn availability, and to examine whether the age and the duration of previous fasting affect Mn absorption, sucking rats were given human milk, bovine milk and infant formula (regular Similac; Ross Laboratories, Columbus, OH) extrinsically labelled with 54Mn.2. Milk diets were given by gastric intubation and the radioactivity of the carcass, liver and digestive tract was measured 3 h after feeding.3. The concentration of endogenous Mn was lowest in human milk (7–10 μg/l) and highest in rat milk (140–165 μg/l). Increasing the non-radioactive total Mn concentrations of either human milk or bovine milk up to 150 μg/l did not affect the absorption of 54Mn by 10-d-old rats.4. No significant (P> 0.05) difference in 54Mn absorption was found among the three milk diets (human milk, bovine milk, infant formula) in 8- to 11-d-old rats. However, significantly more (P< 0.05) 54Mn was absorbed from human milk and infant formula than from bovine milk when 13-d-old rats were used.5. 54Mn radioactivity detected in carcasses of 8-, 9-, 10- and 11-d-old rats ranged from 25 to 27% of the dose from various milk diets. The activities of 54Mn in the carcasses of 13-d-old rats were 15, 11, and 16% of the dose from human milk, bovine milk and infant formula respectively.6. The trend of 54Mn incorporation into liver was similar to that of the carcass and over 60% of the absorbed 54Mn was incorporated into the liver regardless of the type of milk used.7. Absorption of 54Mn from extrinsically labelled rat milk using 9- or 10-d-old sucking rats was similar to its absorption from infant formula.8. The absorption of 54Mn from the three milk diets decreased with age of the neonatal rats and 54Mn absorption from human milk, bovine milk, infant formula as well as rat milk was affected similarly by duration of previous fasting.

Dose Dependent

Oligosaccharides are complex, non-digestible glycans found in large abundance in human milk. The abundance and the profile of bovine milk oligosaccharides and bovine milk based in infant formula differ from those in human milk. Recently, some human milk oligosaccharides (HMOs) have been supplemented to infant formula, however, not all forms have been available in large scale. The objective of the study was to investigate the dose-dependent effects of an enzymatically-synthesized 6′-sialyllactose (6′-SL) sodium salt supplemented to swine milk replacer on growth, hematological parameters, and organ microscopic assessment in our pre-clinical neonatal pig model. Two-day-old male and female pigs (n = 47) were provided one of four experimental diets for 21 days. Diets were formulated to contain 0 (CON), 300 (LOW), 600 (MOD), or 1200 (HIGH) mg/L of 6′-SL sodium salt. On days 8 and 22, samples were collected for hematological and histological analyses. Supplemental 6′-SL sodium salt at all doses supported growth and development comparable to those observed in control animals. In addition, serum chemistries, hematology, and organ microscopic structure were unaffected by 6′-SL (p > 0.05). Thus, addition of enzymatically-synthesized 6′-SL to a milk replacer formula supported growth and clinical outcomes similar to the control formula in the neonatal piglet.

Breastfed Infants

The immune system of the infant is functionally immature and naïve. Human milk contains bioactive proteins, lipids, and carbohydrates that protect the newborn and stimulate innate and adaptive immune development. This review will focus on the role human milk oligosaccharides (HMO) play in neonatal gastrointestinal and systemic immune development and function. For the past decade, intense research has been directed at defining the complexity of oligosaccharides in the milk of many species and is beginning to delineate their diverse functions. These studies have shown that human milk contains a higher concentration as well as a greater structural diversity and degree of fucosylation than the milk oligosaccharides in other species, particularly bovine milk from which many infant formulae are produced. The commercial availability of large quantities of certain HMO has furthered our understanding of the functions of specific HMO, which include protecting the infant from pathogenic infections, facilitating the establishment of the gut microbiota, promoting intestinal development, and stimulating immune maturation. Many of these actions are exerted through carbohydrate-carbohydrate interactions with pathogens or host cells. Two HMOs, 2′-fucosyllactose (2′FL) and lacto-N-neotetraose (LNnT), have recently been added to infant formula. Although this is a first step in narrowing the compositional gap between human milk and infant formula, it is unclear whether 1 or 2 HMO will recapitulate the complexity of actions exerted by the complex mixture of HMO ingested by breastfed infants. Thus, as more HMO become commercially available, either isolated from bovine milk or chemically or microbially synthesized, it is anticipated that more oligosaccharides will be added to infant formula either alone or in combination with other prebiotics.

Abstract Objectives To evaluate growth through 24 months of age in infants receiving added bovine milk fat globule membrane (MFGM) in infant formula through 12 months of age. Concentration of MFGM from bovine milk fractions and incorporation in infant formula may better approximate the composition of complex milk lipids in human milk. Methods In the double-blind, randomized, controlled Chilean Infant Nutrition Trial (ChiNuT; NCT0262613), term infants whose mothers chose to initiate exclusive infant formula feeding before 4 months of age were randomized to receive: a standard cow's milk-based infant formula (SF, n = 174) or a similar formula with added whey protein-lipid concentrate (5 g/L; source of bovine MFGM) (bMFGM, n = 176). A reference group of infants exclusively receiving human milk (HM, n = 236) was also recruited. Growth through 24 months of age was the primary outcome. Length-for-age (LAZ), weight-for-age (WAZ) and body mass index (BMI)-for-age (BAZ) growth z-scores were analyzed by mixed-effects multiple linear regression models adjusted by sex, age (days), and maternal pregestational BMI (kg/m2). Results No significant group differences in sex, gestational age at birth, birthweight, maternal age and maternal education were detected, with the exception of maternal pregestational BMI (mean(SD)) (HM: 27.0(5.2) lower vs SF: 28.6(6.2) or bMFGM: 28.9(6.1); P = 0.002). Groups were similar at baseline (weight, length, WAZ, BAZ) with the exception of LAZ (lower in the bMFGM compared to HM group; P < 0.05). No significant differences in growth z-scores (absolute at 6, 9, 12, and 24 months of age or change between baseline and each study time point) were detected between SF and MFGM groups. Both randomized study formula groups were associated with higher growth z-score increases from baseline compared to the HM reference group between 6 and 24 months (P less than 0.05). Mean growth z-scores fell within the range of −1 to 1 (16th to 84th percentile) for SF, bMFGM, and HM groups at all study time points. Conclusions Added bovine MFGM in a routine cow's milk-based infant formula through 12 months of age supported normal growth through 24 months of age. Funding Sources The study was funded by Mead Johnson Nutrition (MJN). Teresa Murguia-Peniche, Steven Wu, and Jennifer Wampler are currently employed by MJN.

Abstract Human milk has antimicrobial compounds and immunomodulatory activities. We investigated glycerol monolaurate (GML) in human milk versus bovine milk and infant formula for antimicrobial and anti-inflammatory activities. Human milk contained approximately 3000 µg/ml of GML, compared to 150 μg/ml in bovine milk and none in infant formula. For bacteria tested (Staphylococcus aureus, Bacillus subtilis, Clostridium perfringens, Escherichia coli), except Enterococcus faecalis, human milk was more antimicrobial than bovine milk and formula. The Enterococcus faecalis strain, which was not inhibited, produced reutericyclin, which is an analogue of GML and functions as a growth stimulant in bacteria that produce it. Removal of GML and other lipophilic molecules from human milk by ethanol extraction resulted in a loss of antibacterial activity, which was restored by re-addition of GML. GML addition caused bovine milk to become antimicrobial. Human milk but not bovine milk or formula inhibited superantigen and bacterial-induced IL-8 production by model human epithelial cells. GML may contribute beneficially to human milk compared to bovine milk or infant formula.
