Taihu pig
The Taihu pig () is a domestic breed from the narrow region of mild sub-tropical climate around the Taihu Lake region in the lower Yangtze River Valley of China. The breed is a large one, black in colour with a heavily wrinkled face. It has a large head with a broad forehead and large folded ears.〔Mike R. Taverner, A. C. Dunkin, "Pig production", ''World Animal Science'', vol.10C: Production System Approach, p.337, Elsevier Health Sciences, 1996 ISBN 0-444-88347-9.〕〔("Fengjing" ) @ (''Oklahoma State University: Department of Animal Science'' )〕 The breed has a number of divisions, classified by some authors as strains〔Taverner and Dunkin 1996, following Zhang, 1986.〕 and by others as separate breeds.〔Flanders, 2009.〕
All the Taihu strains have a high rate of reproduction with litter sizes ranging up to twenty, but averaging fourteen live piglets. This characteristic, as well as their resistance to disease, has resulted in interest in the pigs for research into breeding and genetic engineering. Taihu pigs have been established in France, Albania, Hungary, Japan, the UK and the US.〔
==Taihu pig strains==
There are usually four main groups of the Taihu pig identified and these are listed below. Although many others are named by authors, it is debatable whether there is any substantial genetic difference as some variation is due to diet and environment rather than genetics. Taihu are kept well-fed on a vegetable diet with large amounts of roughage, which sometimes leaves them short of calcium for bone development.〔〔("Taihu Pig" ) @ (''International Livestock Research Institute'': Training Resource ).〕
