[Effect of endogenous factors on ash, calcium, magnesium, potassium, sodium, phosphorus, zink, iron, copper and manganese concentration in the pig bristle. 6. Effect of gender on mineral composition of pig bristle]. 1978

A Hennig, and W Gumz, and W von Gagern

Sex-specific hormones were found to influence the bristle's mineral content. The bristles of female (N=151) and male (N=152), 42-day old piglets did not differ in the proportion of the elements under study (P greater than 0.05). The bristles of 36 female and 36 male castrated fattening pigs in the 40-110 kg weight range did not reveal significant differences either (P greater than 0.05). The bristles of sows and boars showed differences in the contents of ash, Mg, K, Na, P, Zn and Mn (P greater than 0.05) as well as in the contents of Fe (P greater than 0.01) and Cu (P greater than 0.05). The difference for the Ca-content could not be statistically secured (P greater than 0.05). The content of the bristle or hair of sexually mature animals in certain elements is influenced by sex hormones and should be regarded as a secondary sexual characteristic.

UI	MeSH Term	Description	Entries
D007501	Iron	A metallic element with atomic symbol Fe, atomic number 26, and atomic weight 55.85. It is an essential constituent of HEMOGLOBINS; CYTOCHROMES; and IRON-BINDING PROTEINS. It plays a role in cellular redox reactions and in the transport of OXYGEN.	Iron-56,Iron 56
D008274	Magnesium	A metallic element that has the atomic symbol Mg, atomic number 12, and atomic weight 24.31. It is important for the activity of many enzymes, especially those involved in OXIDATIVE PHOSPHORYLATION.
D008297	Male		Males
D008345	Manganese	A trace element with atomic symbol Mn, atomic number 25, and atomic weight 54.94. It is concentrated in cell mitochondria, mostly in the pituitary gland, liver, pancreas, kidney, and bone, influences the synthesis of mucopolysaccharides, stimulates hepatic synthesis of cholesterol and fatty acids, and is a cofactor in many enzymes, including arginase and alkaline phosphatase in the liver. (From AMA Drug Evaluations Annual 1992, p2035)
D010758	Phosphorus	A non-metal element that has the atomic symbol P, atomic number 15, and atomic weight 31. It is an essential element that takes part in a broad variety of biochemical reactions.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
D002118	Calcium	A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
