Abstract Changes in maternal nutrition that represent inadequacies or excesses in nutrient supply have been implicated in altered fetal development as well as offspring outcomes and have been termed fetal or developmental programming. Research in the area of developmental programming of livestock has greatly increased during the last two decades. For ruminants, most research efforts in developmental programming have focused on nutritional perturbations during the last two-thirds of gestation. Unfortunately, research investigating changes to maternal nutrient supply during early gestation or ev

The risk for non-communicable diseases in adulthood can be programmed by early nutrition. This programming is mediated by changes in expression of key genes in various metabolic pathways during development, which persist into adulthood. These developmental modifications of genes are due to epigenetic alterations in DNA methylation patterns. Recent studies have demonstrated that DNA methylation can be affected by maternal or early postnatal diets. Because methyl groups for methylation reactions come from methionine cycle nutrients (i.e., methionine, choline, betaine, folate), deficiency or supp

Abstract Pregnancy represents a critical period in fetal development, such that the prenatal environment can, in part, establish a lifelong trajectory of health or disease for the offspring. Poor nutrition (macro- or micronutrient deficiencies) can adversely affect brain development and significantly increase offspring risk for metabolic and neurological disease development. The concentration of dietary methyl-donor nutrients is known to alter DNA methylation in the brain, and alterations in DNA methylation can have long-lasting effects on gene expression and neuronal function.

Interest in nutrient loading of seeds is fuelled by its central importance to plant reproductive success and human nutrition. Rates of nutrient loading, imported through the phloem, are regulated by transport and transfer processes located in sources (leaves, stems, reproductive structures), phloem pathway and seed sinks. During the early phases of seed development, most control is likely to be imposed by a low conductive pathway of differentiating phloem cells serving developing seeds. Following the onset of storage product accumulation by seeds, and, depending on nutrient species, dominance

AbstractThe emphasis in nutritional studies on foetal growth has now moved from the last trimester of pregnancy, when most of the increase in foetal size takes place, to earlier stages of pregnancy that coincide with foetal organogenesis and tissue hyperplasia. At these stages absolute nutrient requirements for foetal growth are small but foetal metabolic activity and specific growth rate are high. It is thus a time when nutrient supply interacts with maternal factors such as size, body condition and degree of maturity to influence placental growth and set the subsequent pattern of nutrient pa

Maternal malnutrition gives rise to both short- and long-term consequences for the survival and health of the offspring. As the intermediary between mother and fetus, the placenta has the potential to interpret environmental signals, such as nutrient availability, and adapt to support fetal growth and development. While this potential is present, it is clear that at times placental adaptation fails to occur resulting in poor pregnancy outcomes.

Abstract Objectives Gestational diabetes mellitus (GDM) is associated with alterations in DNA methylation in the placenta and offspring tissues. Nutrients participating in the methionine cycle (e.g., choline, betaine, folate, vitamin B12, methionine) influence the supply of methyl groups. The objective of this research was to determine whether maternal intake and status of these nutrients during pregnancy may interact with the GDM status to shape the offspring epigenome. Methods We conducted 3-day dietary recalls and collected blood samples from pregnant women with and without GDM (n = 22/grou

Ovine placental lactogen (oPL) is postulated to be involved in the repartitioning of maternal nutrients during pregnancy, through its effect on insulin metabolism. Ovine pancreatic insulin responses to exogenous glucose are depressed during pregnancy and this depression becomes more pronounced as gestation advances. In addition, under the hormonal environment of rising oPL and growth hormone (oGH) concentrations, maternal whole body glucose irreversible loss (GIL) increases.

Maternal age on both ends of the reproductive spectrum (teenage and 35+) is associated with increased risk of adverse pregnancy outcomes, as compared with the age range from 20–34 years old. Some of the increase in pregnancy complications in older mothers is caused by underlying age-related health issues such as hypertension and diabetes, the prevalence of which increases linearly with age. The risks associated with young maternal age are more related to nutritional deficits and the fact that pregnant adolescents may still be growing themselves.

Perinatal experiences during a critical developmental period program brain structure and function “for life,” thereby determining vulnerability to psychopathology and cognition in adulthood. Although these functional consequences are associated with alterations in HPA-axis activity and hippocampal structure and function, the underlying mechanisms remain unclear.

AbstractA woman’s body mass index and nutritional status should be assessed in the antenatal period. The evidence indicates that maternal anemia is a risk factor for preterm birth. Ensuring adequate levels of iron and folic acid is essential for general pregnancy health and outcomes. To reduce the risk of pre-eclampsia, daily calcium supplementation for populations with low dietary calcium intake may be advised, although negative interactions between iron and calcium supplements may occur so these two nutrients should be administered several hours apart. In undernourished populations, balanced energy and protein supplementation should also be recommended for pregnant women (though not specifically linked to a reduction in preterm birth). For populations at risk of vitamin D deficiency, possible benefits for general pregnancy outcomes may be gained from vitamin D supplementation. Where dietary zinc is low, it has been suggested that zinc supplementation may reduce the risk of preterm birth. However, further research is required to clarify the benefits of supplementation. For example, vitamin D in combination with calcium may increase the risk of preterm birth. In the antenatal period, the most important focus should be on promoting a good quality diet in general, rather than a specific supplementation regime.

AbstractIn Tanzania, about 90% of the banana-coffee-based farming systems lie in the hands of smallholder farmer families. In these systems, smallholder farmers traditionally add farm waste to crop fields, making soils rich in organic matter (humus) and plant-available nutrients. Correspondingly, soils remained fertile during cultivation for over a century. Since the 1960s, the increasing demand for food and biofuels of a growing population has resulted in an overuse of these farming systems, which has occurred in tandem with deforestation, omitted fallows, declined farm size, and soil erosion. Hence, humus and nutrient contents in soils have decreased and soils gradually degraded. Inadequate use of farm waste has led to a further reduction in soil fertility, as less organic material is added to the soils for nutrient supply than is removed during harvesting. Acknowledging that the traditional use of farm waste successfully built up soil fertility over a century and has been reduced in only a few decades, we argue that traditional composting practices can play a key role in rebuilding soil fertility, if such practices are adapted to face the modern challenges. In this chapter, we discuss two cases in Tanzania: one on the traditional use of compost in the Kagera region (Great African Rift Valley) and another about adapted practices to produce compost manure in the Morogoro region (Uluguru Mountains). Both cases refer to rainfed, smallholder banana-coffee-based farming systems. To conclude, optimised composting practices enable the replenishment of soil nutrients, increase the capacity of soils to store plant-available nutrients and water and thus, enhance soil fertility and food production in degraded banana-coffee-based farming systems. We further conclude that future research is needed on a) nutrient cycling in farms implementing different composting practices and on b) socio-economic analyses of farm households that do not successfully restore soil fertility through composting.

In agriculture, according to the data of the statistical collection, the production of grain crops occupies a large part. At the moment, much attention is paid to the study of perennial crops: Gray Wheatgrass (Latin Thinopyrum intermedium), Trititrigia (Latin Trititrigia cziczinii Tsvelev). These crops help slow soil erosion and minimize nutrient leaching. The non-cereal part of cultivated plants is an important reserve for strengthening the fodder base of animal husbandry and expands the range of sources of raw materials for the microbiological industry in the production of fodder proteins.

Aquaponic systems combine recirculating aquaculture (growing of fish) with hydroponics (growing of plants in water). The fish in the recirculating aquaculture systems provide nutrients for the plants and the plants remove excess nutrients from the water, making these systems more efficient than traditional farming methods in terms of nutrient utilization. Small, recirculating aquaponic systems may provide a more sustainable and cost-effective alternative for securing food supply in both developing and developed nations. Recirculating aquaculture systems tend to be capital-intensive and require

Poor nutritional supply has been a major concern for the health of intervertebral disc (IVD) since the IVD is the largest avascular tissue in the human body. The transport of vital nutrients to cells relies on diffusion and convection through the extracellular matrix (ECM) in the IVD. Transport and metabolism of nutrients (e.g., oxygen and glucose) within the IVD depend on many factors, including the material properties of ECM (e.g., permeability, elastic modulus, and solute diffusivity), cellular metabolic rates, nutritional supply at the edge of the IVD, and mechanical loading [1–6].

Hypothesis and Objectives: We hypothesized that coal combustion products (CCPs), including those created during scrubbing of sulfur dioxide from flue gases, can be used alone or mixed with composted animal manures as effective growth media for plants. Our specific objectives were, therefore, to (1) measure the chemical, physical and hydraulic properties of source materials and prepared mixes, (2) determine the optimum design mix of CCPs and composted animal manures for growth of plants, (3) evaluate the leachate water quality and plant uptake of selected elements from prepared mixes, (4) quant

Pod-filling, an important yield-determining stage is strongly influenced by water stress. This is particularly true for peanut (Arachishypogaea), wherein pods are developed underground and are directly affected by the water condition. Pod-filling in peanut has a significant genetic component as well, since genotypes are considerably varied in their pod-fill (PF) and seed-fill (SF) potential. The goals of this research were to: Examine the effects of genotype, irrigation, and genotype X irrigation on PF and SF. Detect global changes in mRNA and metabolites levels that accompany PF and SF.
