What is animal ethnology or animal breeding ?
The study and comparison of the different breeds of animals, their characteristics, their classification and their regulation
What is zootechnics ?
The study of specific characteristics, production parameters, husbandry and classification of the ( domestic ) animal breeds in order to obtain the best performance while taking into account animal welfare
What are the characteristics to define a breed ?
A breed needs to fulfill an homogeneity of characters genetically determined
What are the genetic characters that characterize a breed ?
Physiological-productive
Morphological
what is the definition of a breed according to Sierra ?
A breed is a technic-scientific concept that identifies and differentiates a group of animals depending on certain characteristics that are inherited to the offspring but, also maintain certain variability and dynamic evolution
What is the sceptic concept ?
Group of animals determined to be a breed by some individuals at particular positions on Administration : ex : when two breeds couple to form a new breed
What are the different zootechnical classification of breeds ?
origin : geographical distribution
Physical characteristics : general features or morphology
Production or functional characteristics : aptitude and farming system
What does it mean zootechnical classification of breeds ?
It means that the species must have the same characteristics to be part of the same breed : ex : these two cows are from the same specie ( Bos Taurus ) but not the same breed because they have different morphologies
What is breed genesis ?
The formation of a new breed
What are the breed genesis ?
Geographical breeds : isolation
Zootechnical breeds : inherited characteristics ( utility selection, selection of the best, uniformity )
Example of geographical breeds : isolation
Ouessant and Breton dwarf sheep were isolated on an island and evolved to become a new breed due to changes
Exemple of zootechnical breeds : inherited characteristics
Cattle used in dairy production were bred according to desired characteristics ( big milk yield, calm ) creating a desirable breed for production
Why is it important to form breeds ?
Generates uniformity : for similar looking / behaving animals
Allows us to control productivity : allows us to make predictions in production
Makes possible hybridation : cross-breeding can allow us to get the best characteristics of 2 different breeds + hybrid vigour = mixed breeds are stronger
Creates associations : farmers interested in productivity + breeders interested in beauty
Exemple for uniformity as an importance to form breeds
All are similar size, so fit into standard cages
Exemple for control productivity as an importance to form breeds
We can predict the amount of milk produced by breed
Exemple for hybridation as an importance to form breeds
Labradoodle : mix between a Labrador ( friendly ) and a Poodle ( curly hair )
Exemple for association as an importance to form breeds
La asociación criadores de caballos del sur ( ACCSUR )
What does breed variations mean ( variety ) ?
Animals within a breed can differentiate on some characteristics : ex : one breed ( Poodle ) but with different colors
What does breed ecotype mean ?
Variants inside a breed due to geographical variations
What does breed group mean ?
Group of animals with a visual characteristic uniformity but not demonstrated homogeneity ( look the same but aren’t )
What is a breed standard ?
A guideline that describes the ideal characteristics, temperament and appearance
How do we establish a breed standard ?
A complete study of the breed with the aim to describe
A breed pattern must be established
A serie of general and specific parameters
What are the main parts of a breed standard ?
Origin : historic / genetic background
Area of origin : ecologic characteristics of the area
Dispersion area : current location
Morphological description : general morphology ( weight, height… ) + regional morphology ( head, neck, trunk, limbs… ) + special features ( ears, eyes, tail, sexual organs… ) + phaneroptic ( skin and related structures : coat, fur, horns, hair… ) + color ( coat, skin, mucous… )
Productive description : aptitude
Improvement programs
Breed studies
What is the pedigree ?
Record of the genealogy of purebred animals : provides animal’s purity, traceability and authenticity
What is an animal’s purity ?
Ancestry
What is an animal’s traceability ?
Name or unique ID number
