Breeding without Breeding: Is a Complete Pedigree Necessary for Efficient Breeding?

PLoS ONE, 2011
Complete pedigree information is a prerequisite for modern breeding and the ranking of parents and offspring for selection and deployment decisions. DNA fingerprinting and pedigree reconstruction can substitute for artificial matings, by allowing parentage delineation of naturally produced offspring.

Comparison of fatty acid composition in milk fat of Czech Pied cattle andHolsteincattle

Czech Journal of Animal Science, 2005
In May 2003 differences in milk fat composition in two main dairy breeds in the Czech Republic, Czech Pied cattle and Holstein cattle, were studied in two uniform groups, each containing eight cows.

Unraveling signatures of chicken genetic diversity and divergent selection in breed-specific patterns of early myogenesis, nitric oxide metabolism and post-hatch growth

Frontiers in Genetics, 2023
Introduction: Due to long-term domestication, breeding and divergent selection, a vast genetic diversity in poultry currently exists, with various breeds being characterized by unique phenotypic and genetic features.

Comparison of calf rearing results and nursing cow performance in various beef breeds managed under the same conditions in north-western Poland

Czech Journal of Animal Science, 2007
We compared the results of calf maternal nursing and cow performance in 5 beef breeds managed under equal conditions in the region of West Pomerania. The study involved 549 cows and 1 979 calves (1 007 heifers and 972 bulls) of the following breeds: Red ...

History and structure of the closed pedigreed population of Icelandic Sheepdogs [PDF]

, 2009
Background Dog breeds lose genetic diversity because of high selection pressure. Breeding policies aim to minimize kinship and therefore maintain genetic diversity.

Dual origins of dairy cattle farming--evidence from a comprehensive survey of European Y-chromosomal variation

, 2011
BACKGROUND: Diversity patterns of livestock species are informative to the history of agriculture and indicate uniqueness of breeds as relevant for conservation.

Metagenomic Sequencing Revealed Differences in the Composition of Cecal Microbes in Different Breeds of Chickens

Animals, 2023
Intestinal microorganisms are closely related to the health, development, and production performance of animals and can also provide basic information for us to fully understand and explore the germplasm characteristics and traits of local chicken breeds.

Genetic diversity and structure of livestock breeds [PDF]

, 2012
This thesis addresses the genetic characterisation of livestock breeds, a key aspect of the long-term future breed preservation and, thus, of primary interest for animal breeders and management in the industry.
