Bile salt-stimulated lipase activity in human colostrum from mothers of infants of different gestational age and birthweight.

1987

. The bile salt-stimulated lipase (BSSL) activity was measured in milk collected at 3–4 days postpartum (colostrum) from 36 mothers divided into three groups according to gestational age and birthweight of their infants. BSSL activity changed with the length of gestation. Preterm colostrum presented a mean activity significantly higher than the term groups (small-for-gestational age and appropriate-for-gestational age) which had similar values. The ratio of BSSL activity to the estimated fat content was 6.33 in colostrum of mothers who delivered preterm and 4.20 in colostrum of both groups of term mothers. These data suggest that preterm colostrum has a higher fat digesting potential than t…

Impact of lactation stage, gestational age and mode of delivery on breast milk microbiota.

2014

There is an increasing evidence of the immunological role of breast milk (BM) microbiota on infant health. This study aims to analyze several determining factors of milk microbiota. A total of 96 milk samples from 32 healthy mothers (19 preterm vs 13 at term gestations; and 15 vaginal deliveries vs 17 Cesarean sections) were longitudinally collected. Microbiota composition was studied by quantitative PCR and the influence of lactation stage, gestational age and delivery mode was evaluated. Globally, Lactobacillus, Streptococcus and Enterococcus spp. were the predominant bacterial groups. Total bacteria, Bifidobacterium and Enterococcus spp. counts increased throughout the lactation period. …

Melatonin Content of Human Milk: The Effect of Mode of Delivery

Objective: Cesarean section rates are increasing in developed countries and could be performed as an emergency or elective procedure. Our research aim was to determine whether elective cesarean sec...

Human sweat odour conjugates in human milk, colostrum and amniotic fluid

2012

International audience; Using ultra performance liquid chromatography-mass spectrometry we identified for the first time glutamine-N-alpha-conjugates of the fatty acids (E)/(Z)-3-methylhex-2-enoic acid and (R)/(S)-3-hydroxy-3-methylhexanoic acid as well as cysteinylglycine-S-conjugates of (R)/(S)-3-methyl-3-sulphanylhexan-1-ol and (R)/(S)-3-sulphanylhexan-1-ol as constituents of human milk and colostrum. The glutamine-N-alpha-conjugates were detected also in human amniotic fluids. The mean values of glutamine-N-alpha-conjugate of (R)/(S)-3-hydroxy-3-methylhexanoic acid were highest in colostrums with a range of <0.1-382 mu g/kg, followed by the mature human milk with values from <0.1 to 39.…

The effects of ultrasonication, fermentation with Lactobacillus sp., and dehydration on the chemical composition and microbial contamination of bovin…

2018

The aim of this study was to evaluate the influence of ultrasonication, fermentation with Lactobacillus plantarum LUHS135 and Lactobacillus paracasei LUHS244, and different methods of dehydration on the chemical composition of bovine colostrum (BC), including the fatty acid and free amino acid profile and the content of micro- and macroelements. In addition, we analyzed the changes in lactic acid bacteria count, microbial contamination (aerobic mesophilic spore-forming bacteria, enterobacteria including Escherichia coli, and fungi/yeasts), the abundance of biogenic amines, and the concentration of nucleotide monophosphates. Significant effects of different treatments on the free amino acid …

Effect of lambing season on ewe’s colostrum composition

2023

Colostrum provides newborns with nutrients and immunoglobulins that play a major role in the immune system. In this survey, the immunoglobulin G (IgG) content, gross composition, mineral content, and fatty acid composition were determined in the colostrum of Valle del Belice ewes with the aim of evaluating the effect of lambing of season. In total, we analysed 60 bulk tank colostrum samples taken after lambing during two seasons (summer and winter). The IgG con- tent and Brix mean values were 40.35 g/L and 21.02%, respectively. The colostrum fat, protein, casein, and lactose percentages were 8.01, 12.10, 8.51, and 3.13%, respectively. The lambing sea- son significantly influenced the pH and…

Chemometric Approaches to Analyse the Composition of a Ewe’s Colostrum

2023

Colostrum is a major source of immunity in lambs and, in general, in all newborn ruminants. It allows the transfer of antibodies from the ewe to the lamb, and it becomes the exclusive source of nutrients for a newborn. Among the most significant Pearson correlations, the positive correlation between the Brix refractive index (Brix) and protein (0.90) should be noted. Both parameters (protein percentage and Brix) were then positively correlated with the percentage of fat (0.38 and 0.41), urea (0.81 and 0.67), calcium (0.39 and 0.29), and magnesium (0.58 and 0.59), as well as the yellowness (0.78 and 0.75). Somatic cell count (SCC) and pH, parameters which are indicators of subclinical mastit…

Effects of bovine colostrum supplementation on serum IGF-I, IgG, hormone, and saliva IgA during training.

1997

Mero, Antti, Heidi Miikkulainen, Jarmo Riski, Raimo Pakkanen, Jouni Aalto, and Timo Takala. Effects of bovine colostrum supplementation on serum IGF-I, IgG, hormone, and saliva IgA during training. J. Appl. Physiol.83(4): 1144–1151, 1997.—The purpose of this study was to examine the effects of bovine colostrum supplementation (Bioenervi) on serum insulin-like growth factor I (IGF-I), immunoglobulin G, hormone, and amino acid and saliva immunoglobulin A concentrations during a strength and speed training period. Nine male sprinters and jumpers underwent three randomized experimental training treatments of 8 days separated by 13 days. The only difference in the treatments was the drink of 125…
