Article Abstract
Background: The composition of breast milk is dependent on numerous factors. However, the precise impact of maternal health conditions on breast milk composition remains to be fully elucidated. Similarly, there is a paucity of evidence regarding the correlation between neonatal body composition and human milk. The objective of the study was to evaluate the macronutrient composition of breast milk collected during the first week postpartum from mothers with gestational diabetes and healthy mothers in terms of selected maternal and neonatal factors.
Methods: = 70 breast milk samples were analyzed for fat, protein, carbohydrate, dry matter, true protein, and energy. The results were evaluated in terms of selected maternal factors, as well as neonatal birth weight (BW) and percent fat body mass (%FBM), which was assessed with a bioimpedance method.
Results: Energy of breast milk in the study group was as follows: median 55.5 kcal/dL in GDM G1, median 55.5 kcal/dL in GDM G2, and median 65.0 kcal/dL in non-GDM, which differed significantly in Kruskal-Wallis ANOVA. Neonatal %FBM, but not BW, was found to be significantly related to concentrations of protein, true protein and dry matter. Maternal gestational weight gain, history of hypothyroidism, and classification by study group were identified as factors affecting both breast milk and neonatal body composition.
Conclusions: The composition of breast milk in the initial week following childbirth is predominantly determined by maternal factors. The relationship between selected macronutrients and neonatal percent fat body mass was found to be weak, yet the significance of this finding is unclear. Further research is required to ascertain the influence of maternal milk composition on early infantile nutritional programming.

The mammary gland, which primarily develops postnatally, undergoes significant changes during pregnancy and lactation to facilitate milk production. Through the generation and analysis of 480 transcriptomes, we provide the most detailed allelic expression map of the mammary gland, cataloguing cell-type-specific expression from ex-vivo purified cell populations over 10 developmental stages, enabling comparative analysis. The work identifies genes involved in the mammary gland cycle, parental-origin-specific and genetic background-specific expression at cellular and temporal resolution, genes associated with human lactation disorders and breast cancer.

Recent years have seen advances in clinical biochemistry of domestic animals which have highlighted comparative differences between species and have also identified fundamental aspects of the biochemical mechanisms in physiological conditions and disease, that have implications across species, including human, health and welfare. From investigations in diverse species using biochemical, immunological, proteomic and metabolomic approaches a series of species particularities and unexpected results for some biomarkers have been made. These observations cover (1) the differences between species in the acute phase protein (APP) response to infection and inflammation; (2) the non-hepatic synthesis and release in the mammary gland, adipose tissue and intestine of APP (3) the response of haptoglobin (HP) as a biomarker for stress; (4) observations in non-mammalian species related to hemopexin and HP; (5) the response of bile acids in milk to mastitis; (6) barley serine protease inhibitors being identified in bovine faeces; (7) alkaline phosphatase being present in bovine nasal secretion; (8) saliva findings with analytes such as adenine deaminase showing different activity between saliva and serum and a detergent-like surfactant protein, latherin being found in equine saliva and sweat and (9) serum enzymes and selective muscle protein reaction of Atlantic salmon as an example of the differences in biochemistry between terrestrial and aquatic species.

There is a need for sustainable food production and processing that reduces resource use and increases the availability of nutritious, innovative, and sustainable food. A coordinated, multisectoral approach across the food supply chain is essential to address global food and nutrition insecurity. The dairy industry produces abundant bioactive compound streams that can be examined for their valuable functionalities.
