Distribution of cobalt, manganese and iron in the skin and hair of West African dwarf sheep and goats in Nigeria

Abstract

The distribution of cobalt (Co), manganese (Mn) and iron (Fe) was investigated in the skin and hair of 16 West African Dwarf sheep and goats. All three trace elements were present in varying amounts in both tissues. There were, however, some regional intraand interspecies differences Some of these differences were found to be statistically significant. These findings are discussed with reference to their possible implications for cutaneous manifestation of deficiency and other disease syndromes in the animals.

Chemical composition and rumen fermentation profile of mangrove leaves (Avicennia marina) from West Sumatra, Indonesia

“…Nugroho (2008) states that Mn functions as carbohydrate synthesis, mucopolysaccharide, and enzyme systems, such as pyruvate carboxylase and arginine synthetase. In addition to enzymatic reactions, Mn also functions for growth and reproduction of livestock, Onwuka et al (2001) which states that Mn's mineral content in goats ranges from 2.98-13.9 mg/dl. Based on these data, it can be concluded that the livestock reared with A. marina leaf-based feed does not experience Mn mineral deficiency because the Mn content in the forage is sufficient.…”

Parchment characterization by multiphoton electron extraction spectrometry

“…This assumption is supported by a recent report on the higher density of collagen fibrils in calf and goat parchments, compared with a more open weave and higher fat content in sheep parchments (Fiddyment et al, 2015). Other differences between the animal species could also contribute to the distinction in MEES results (Onwuka et al, 2001).…”
