“…Maternal liver Cu was negatively correlated with fetal age, this results agree with the results obtained by (Gonneratne and Christensen, 1989b). While (Graham et al, 1994) found that maternal liver Cu was not correlated with fetal size.…”

Problem statement: Samples of allantoic, amniotic fluid, fetal liver, kidney, maternal plasma and liver were collected from 30 ewes and classified into either early or late gestation and copper concentrations were measured. Approach: The Cu concentrations in the maternal plasma, allantoic, amniotic fluid, fetal liver and kidney increased significantly (p<0.01) during late gestation while maternal liver Cu decreased significantly (p<0.01). Results: Significant positive relationships were recorded between age of the fetus and Cu concentrations in the allantoic and amniotic fluid (r = 0.71-0.83, p<0.001), fetal liver (r = 0.80, p<0.001), kidney (r = 0.59, p<0.01) and maternal plasma (r = 0.75, p<0.001). Significant (p<0.01) positive relationships were also recorded between the Cu concentrations in the amniotic, allantoic fluid and maternal plasma with fetal liver Cu concentrations (r = 0.36-0.73), the maternal plasma and liver Cu concentrations were significantly negative correlated (r = -42, p<0.05). Conclusion: A significant negative correlation was recorded between the Cu concentrations in the maternal liver and fetal age (r = -0.74, p<0.01). Strong fetal-maternal relationships in Cu concentration were evident throughout the gestational period and dams seem to sacrifice Cu levels in order to maintain that in the fetus. Cu concentrations in the amniotic and allantoic fluids could be used as a possible indicator of the Cu status of the fetus throughout gestation.

“…Ovine maternal and fetal liver Cu were negatively correlated in this and previous reports(Gonneratne and Christensen, 1989b). Presence of significant negative relationship between age of the fetus and maternal liver Cu concentration as well as the relationships between maternal liver and amniotic and allantoic fluid Cu concentrations were significantly negative, while the relationship between age of the fetus and maternal plasma, fetal liver, amniotic fluid, allantoic fluid and fetal kidney Cu concentrations were significantly positive might indicate that, the dam and fetus depended on the maternal liver Cu contents during gestation (Abd Elghany et al, 2011) and liver Cu can be used as an indicator of the Cu status(Johnston et al, 2014) through gestation and fetuses had a capacity to sequester maternal Cu, even when the dam was Cu deficient(Graham et al, 1994) Parkinson (1981).…”

Copper is an important trace element that plays a very important role in the biochemistry of all living organisms and affects enzymes activity as a cofactor or as a fundamental structure of many metalloenzymes as superoxide dismutase, ceruloplasmin, lysyl oxidase, cytochrome oxidase and tyrosinase. Therefore copper is essential for cellular respiration, free radical defence, neurotransmitter function and tissue biosynthesis. Excessive copper accumulation is toxic in all species as it leads to hepatic cirrhosis, hemolytic anemia and degeneration of basal ganglia. The aim of this review is to give a view on the health issue surrounding copper and animal health including many interested points about copper and fetal maternal relationship, the role of copper in the different body system and the effect of its deficiency and toxicity, as well as focusing on the relationship of copper with metalloenzymes, immunity and DNA.

“…Simultaneously, the Se concentration in the serum of calves born to cows fed with Se-enriched yeast was 1.3-fold higher in comparison with that found in calves born to cows that received inorganic salts. The efficiency of Se transfer across the placenta found in this research is lower than that estimated previously in cattle as a correlation of Se concentrations between fetus-dam in liver (r = 0.65; Gooneratne and Christensen 1989) and in whole doi: 10.17221/86/2016-CJAS blood (r = 0.63; Patterson et al 2013). It may be assumed that the main reason for the higher value of this relationship presented in the cited studies was the comparison of Se concentration in the liver and in the whole blood.…”

The aim of this study was to determine the efficiency of diet-cow-calf transfer of selenium (Se) depending on the forms of Se-supplement given to cows of Simmental breed during the last trimester of pregnancy and the first week of lactation. On day 195 of pregnancy the cows were randomly assigned to one of four experimental groups (n = 6), and the newborn calves belonged to the same group as their mothers (n = 6). The cows in the control group received diet without Se-supplement, while the supplemented groups received Se in equivalent doses in a powder form (Se-unprotected) or in a protected form (Se-protected) of sodium selenite or in organic compounds (Se-yeast), the calves received colostrum and milk from their mothers. The data about feed and Se intake, colostrum and milk daily production, Se concentration in colostrum, milk, and cows and calves blood serum were recorded. The diet-cow Se transfer efficiency was estimated as the following ratios: the concentration of Se in cows' serum after parturition/daily Se intake during prepartum; Se secretion in colostrum/daily Se intake during prepartum; and Se secretion in milk at 7 days of lactation/daily Se intake. The ratios were higher (P ≤ 0.02) in the Se-yeast group than in the other supplemented groups, in the Se-unprotected and Se-protected groups the ratios were similar (P > 0.05). The cow-calf Se transfer efficiency estimated as calves' serum concentration after birth/cows' serum concentration after parturition was similar (P > 0.05) in all experimental groups. The results showed that the form of Se supplement modulated the Se transfer from the diet to cows; Se was transferred more efficiently from the Se-yeast than from sodium selenite. The form of Se supplement did not affect the cow-calf Se transfer efficiency.
