Summaries of Publications and Articles About Dexters
:
Short or abbreviated accounts of the contents of some important publications.
:
Publications are included because of their historical significance or because they contain important or interesting information. They are summarised as I have not gained permission to reproduce them in their entirety. Inclusion does not mean that I endorse, agree with or support the views presented in them.
:
1) "Bloodlines, Breed Structure, and the Influence of Artificial Insemination in Dexter Cattle" by Andrew Sheppy, a paper presented to the First World Congress on Dexter Cattle held in England in 1998. Congress Proceedings were published by the Dexter Cattle Society (UK) in 1999 in The World of Dexter Cattle. Copies of this publication have now all been sold. Sheppy's paper is based on an examination of the UK Dexter Herd Books. He examines the influence of a number of AI bulls on the UK and global Dexter herd. Focusing on the post-1970 Herd Books, Sheppy identifies eight key bloodlines arising from eight high profile individual animals. The research for this publication and the next one below influenced the decision of the UK Rare Breeds Survival Trust to designate a Dexter "Original Population" as reported in 3) below. A comment by the UK DCS on Sheppy's Paper, in response to an inquiry from the New Zealand DCS, is also included.
:
2) "Introgression and Purity Assessment in Dexter Cattle" by Andrew Sheppy, a paper presented to the Second World Congress on Dexter Cattle held in Australia in 2002. The Congress Proceedings have not been published. This paper follows up the concerns of the previous one and examines the purity of the Dexter stock in the UK. Purity is defined as free from introduced genes from other breeds of cattle. Sheppy presents evidence that there are very few such pure-bred Dexters in the UK.
:
3) "The Dexter is Back" from The Ark, the magazine of the UK Rare Breeds Survival Trust, 2003 - The Dexter breed is back on the Rare Breed Listings in the UK. This short article reports on the identification of a small number of "original type" Dexters to be designated as an "Original Population" of the breed.
:
4) "A DNA Test for Chondrodysplasia in Dexter Cattle" by J.A.L. Cavanagh, I Tammen, P.A. Windsor. P.C. Thomson, F.W. Nicholas and H.W. Raadsma, a paper presented to the Second World Congress on Dexter Cattle held in Australia in 2002. The Congress Proceedings have not been published. At the Congress, Julie Cavanagh presented this paper, announcing her successes in identifying two genes responsible for bulldog calves in Dexters and developing a DNA test for them. Part of the paper also reported on research on the relationship between the height of individual Dexters and whether they carried the chondrodysplasia gene.
:
5) "Royal Farmers" by Ralph Whitlock, a book published by Michael Joseph Ltd, London, 1980. In this book, Whitlock provides a history of the farming activities of the Kings and Princes of British royalty. A summary is provided here of the brief comments made in the book on the royal Dexters, their farmers and their farms.
:
6) "TYRP1 is Associated With Dun Coat Colour in Dexter Cattle or How Now Brown Cow?" by T.G. Berryere, S.M Schmutz, R.J. Schimpf, C.M. Cowan and J. Potter, 2003. This article was published in the scientific journal, Animal Genetics. It reports on research that concluded that the dun gene in Dexters is unique to the breed.
:
7) "The Changing Geography of Rare Livestock Breeds in Britain" by Richard Yarwood and Nick Evans, 1999. This is an academic article by two University Geographers. They examine the patterns of distribution of a number of rare breeds in the context of the rise of "post-productivist" agriculture. Post-productivism is concerned more with diversification, the environment and food quality than specialisation, intensification and food quantity. Dexters are mentioned only in passing, but the context of their history in Britain is provided.
:
8) "Kerry and Dexter" in Two Hundred Years of British Farm Livestock by Stephen J.G. Hall and Juliet Clutton-Brock, 1989. This book presents an account of the development of the different breeds of British cattle, sheep, pigs, goats and horses. Its entry on the Kerry and Dexter contains a brief history of the breeds, along with some data on the number of Dexters in England the first half of the 20th century.
:
9) "Dexter" in Cattle: A Handbook to the Breeds of the World by Valerie Porter, with illustrations by Jake Tebbit, 1991. This is an entry in a book that provides an account of nearly all cattle breeds in the world. Porter emphasises the dual purpose character of the Dexter and comments on the breed's historical relationship to the Kerry.
:
10) "Genetic and Breeding Research in Dexter Cattle Since 1970" by Andrew Sheppy, a paper presented to the First World Congress on Dexter Cattle held in England in 1998. Congress Proceedings were published by the Dexter Cattle Society (UK) in 1999 in The World of Dexter Cattle. Sheppy summarises four main areas of research - the genetics of size; the bulldog calf problem; the development of polling in the Dexter; and the genetics of coat colour and markings.
:
11) "Dexter Cattle: Origin and Relationships" by Lawrence Alderson, a paper presented to the First World Congress on Dexter Cattle held in England in 1998. Congress Proceedings were published by the Dexter Cattle Society (UK) in 1999 in The World of Dexter Cattle. Alderson examines the view that the Dexter is an off-shoot of the Kerry and highlights three areas of research (blood-typing, linear assessment and production characteristics) that show that the modern Dexter has a distant relationship to the Kerry, and does not belong to the Celtic group of breeds, though this may be due to genetic introgression.
:
12) "A Comparative Study of Blood Groups in the Kerry and Dexter Cattle Breeds" by C. Buys and Jy Chiperzak, a chapter in the book, Genetic Conservation of Domestic Livestock, Volume 2, 1992, originally presented as a paper at the second non-governmental meeting on the genetic conservation of domestic livestock, held in Budapest in August 1991. The authors present the results of blood typing analyses to examine the relationship between the Kerry and Dexter breeds. Comparing the blood groups found in 45 Kerries and 45 Dexters led them to conclude that these are two separate breeds.
:
13) "Domestic Animal Genetic Resources in Canada" by J. Chiperzak and J.N.B. Shrestha, extracts from a chapter in the book, Genetic Conservation of Domestic Livestock, Volume 2, 1992, originally presented as a paper at a conference held in Budapest in August 1991. Data are presented on the status of Dexters as a rare breed in Canada.
:
14) "A Contemporary Geography of Indigenous Irish Livestock" by Richard Yarwood, Nick Evans and Julie Higginbottom, published in the journal, Irish Geography, Volume 30, No. 1, 1997, pages 17-30. Includes a discussion, with illustrative maps, of the contemporary distribution of three rare breeds of Irish cattle - the Kerry, Irish Moiled and Dexter.
