“…This result may attributed to egg composition, which includes a calcareous eggshell (Hincke et al, 2012), proteins and peptides in the egg membranes (Makkar et al, 2015), lipids in the yolk (Anderson, 2011), and water and proteins in the albumen (Willems et al, 2014).…”

“…Egg PA values were significantly different between storage times (p<0.05), with eggs store for zero days presenting higher PA values. This may be attributed to the fact that eggs lose water (Willems et al, 2014), and the number of blastodermal cells and the rate of apoptosis are reduced (Hamidu et al, 2010;Hamidu et al, 2011) during storage. The higher R values obtained in eggs stored for seven days is explained by the fact that R is inversely proportional to the body hydration level (Baumgartner et al, 1988;Dou et al, 2011).…”

The need to comply with animal welfare has motivated the research for non-invasive methods that allow the evaluation of poultry and eggs to be painless while providing accurate measurements. In this scenario, bioelectrical impedance was tested as a minimally invasive tool for sexing day-old chicks of two different chicken strains and for evaluating the quality of eggs submitted to different days of storage relative to their hatchability. The resistance and phase angle measured allowed the differentiation between chicken strains, but not between sexes. Eggs stored for seven days showed higher resistance and lower phase angle those stored for only one day. Although the bioimpedance method seems to be a promising method to evaluate egg and chick quality, the results of the present study suggest that further studies are needed to validate its utilization, particularly in terms of electrode type and positioning, as well as for the determination of which electrodes and equipment are best suited for different evaluation purposes.

“…The nutrients used to support the growth of other organisms also argues that direct use of amino acids nutrients is a common means to support cell proliferation. Both fertilized bird eggs and germinating plant seeds are examples of closed systems comprised primarily of protein, amino acid, and lipid stores that support rapid gains in organismal mass in the absence of other exogenous nutrients (Boulter and Barber, 1963; Moran, 2007; Willems et al, 2014). Rapid cell proliferation in these systems is also consistent with the notion that proliferating cells avoid de novo biosynthesis where possible.…”

Amino Acids Rather than Glucose Account for the Majority of Cell Mass in Proliferating Mammalian Cells

Cells must duplicate their mass in order to proliferate. Glucose and glutamine are the major nutrients consumed by proliferating mammalian cells, but the extent to which these and other nutrients contribute to cell mass is unknown. We quantified the fraction of cell mass derived from different nutrients and find that the majority of carbon mass in cells is derived from other amino acids, which are consumed at much lower rates than glucose and glutamine. While glucose carbon has diverse fates, glutamine contributes most to protein, and this suggests that glutamine’s ability to replenish TCA cycle intermediates (anaplerosis) is primarily used for amino acid biosynthesis. These findings demonstrate that rates of nutrient consumption are indirectly associated with mass accumulation and suggest that high rates of glucose and glutamine consumption support rapid cell proliferation beyond providing carbon for biosynthesis.

“…The egg components are readily accessible for manipulation, allowing investigation of strictly nutritional effects. As albumen is the main source of protein for tissue synthesis in the developing embryo (Freeman & Vince 1974), prenatal protein undernutrition can be induced by partial replacement of albumen with saline during early embryonic development (reviewed by Willems et al (2014a)). The main advantage of the use of an avian model is thus the possibility of examination of the direct nutritional effects without inference of secondary maternal (e.g., hormonal) effects.…”

In mammalian models of prenatal undernutrition the maternal diet is manipulated, exerting both nutritional and hormonal effects on the offspring. In contrast, in the chicken, strictly nutritional effects can be applied. Prenatal protein undernutrition in chickens was induced by partial replacement of albumen with saline during early embryonic development (albumen-deprived group) and results were compared with a sham-manipulated and a non-manipulated group. Body weight of the albumen-deprived hens was reduced throughout the entire experimental period (0-55 weeks). The reproductive capacity was diminished in the albumen-deprived hens as reflected in the reduced number of eggs and lower egg weight. The plasma triiodothyronine levels were increased in the albumendeprived group compared with the non-manipulated hens, but not the sham-manipulated hens. An oral glucose tolerance test (OGTT) at 10 weeks of age revealed a decreased glucose tolerance in the albumen-deprived hens. During adulthood, an age-related loss of glucose tolerance was observed in the hens, leading to disappearance of treatment differences in the OGTT. The offspring of the albumen-deprived hens (PA chicks) had reduced body weight until at least 3 weeks of age. In addition, the PA chicks had a decreased relative residual yolk weight at hatching. An insulin tolerance test revealed increased sensitivity to insulin for the PA chicks compared with the offspring of the non-manipulated (PN) and sham-manipulated hens (PS). In conclusion, prenatal protein undernutrition by albumen removal caused long-term effects on body weight, reproductive performance, and physiology.
