Ingestion of iron in sow's faeces by piglets reared in farrowing crates with slotted floors. 1982

P T Gleed, and B F Sansom

1. Two sows were housed in farrowing crates with slotted floors and fed daily with approximately 200 microCi 198Au from 3 d before farrowing until their piglets were 21 d old. 2. Th sows' faeces became radioactive but their milk remained free of radioactivity. The piglets' mean (+/- SE) whole-body radioactivity was equivalent to 8.5 +/- 0.9 g (range 3.8-15.5 g) of faeces. This is probably a measure of their daily intake of faeces. 3. The possibility of using this natural coprophagia to prevent piglet anaemia has been demonstrated on two commercial piggeries by feeding the sows a diet containing 2000 mg Fe/kg.

D000747	Anemia, Hypochromic	Anemia characterized by a decrease in the ratio of the weight of hemoglobin to the volume of the erythrocyte, i.e., the mean corpuscular hemoglobin concentration is less than normal. The individual cells contain less hemoglobin than they could have under optimal conditions. Hypochromic anemia may be caused by iron deficiency from a low iron intake, diminished iron absorption, or excessive iron loss. It can also be caused by infections or other diseases, therapeutic drugs, lead poisoning, and other conditions.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).	Phacochoerus,Pigs,Suidae,Warthogs,Wart Hogs,Hog, Wart,Hogs, Wart,Wart Hog
