Iron deficiency is the most common nutritional deficiency in humans, affecting more than two billion people worldwide. Early-life iron deficiency can lead to irreversible deficits in learning and memory. The pig represents a promising model animal for studying such deficits, because of its similarities to humans during early development. We investigated the effects of pre-weaning dietary iron d...
The trial was carried out at a commercial pig farm in Bukit Pelanduk, Negeri Sembilan, Malaysia. The objective of the study was to assess the efficacy of supplemental iron in drinking water and iron in paste form in comparison with the iron dextran injection. A total of 12 litters were used divided into three treatments : iron dextran injection (ID), Fedexx" - iron in paste form (IP) and Opti-i...
A. Vaško, L. Trško, R. Konečná, Faculty of Mechanical Engineering, University of Žilina, Žilina, Slovak Republic The paper shows the influence of charge composition on microstructure, fatigue properties and failure micromechanisms of nodular cast irons. The additive of metallurgical silicon carbide (SiC) in analysed specimens increases the content of ferrite in the matrix, decreases the size of...
هدف از انجام پژوهش حاضر را می توان بررسی نحوه تاثیر گذاری توامان میزان حضور عناصر نادر خاکی و همچنین سرعت انجماد بر مورفولوژی گرافیت در قطعات ریختگی از چدن با گرافیت فشرده برشمرد. به منظور لحاظ نمودن سرعت های متفاوت انجماد و همچنین شبیه سازی شرایط حضور مقاطع با ضخامت های متفاوت در قطعات ریختگی، در پژوهش حاضر مدل پلکانی به کار گرفته شد. بررسی تاثیر میزان حضور عناصر نادر خاکی بر مورفولوژی گرافیت ...
Among livestock, domestic pig (Sus scrofa) is a species, in which iron metabolism has been most intensively examined during last decade. The obvious reason for studying the regulation of iron homeostasis especially in young pigs is neonatal iron deficiency anemia commonly occurring in these animals. Moreover, supplementation of essentially all commercially reared piglets with iron entails a nee...
