Genetic characterization of french local chicken breeds

, 2017
The small population sizes of French local breeds raise the question of their in situ or ex situ conservation. For that goal the characterization of their genetic diversity with molecular tools appears as a preliminary key step. A total of 22 local breeds and 4 commercial lines with an average of 60 individuals per breed were genotyped using a 57K DNA ...

The landscapes of livestock diversity: grazing local breeds as a proxy for domesticated species adaptation to the environment

Landscape Ecology, 2022
Domesticated animals play a central role in agricultural landscapes. However, livestock has been scarcely studied from a spatial perspective. Mapping of livestock diversity has been limited by the lack of distribution and demography data.

Evolutionary Subdivision of Domestic Chickens: Implications for Local Breeds as Assessed by Phenotype and Genotype in Comparison to Commercial and Fancy Breeds

Agriculture, 2021
To adjust breeding programs for local, commercial, and fancy breeds, and to implement molecular (marker-assisted) breeding, a proper comprehension of phenotypic and genotypic variation is a sine qua non for breeding progress in animal production.

Local breeds and pastoral farming on the North Mediterranean shore: a univocal coevolution? An example of dairy sheep farming systems in Corsica (France) and Thessaly (Greece)

Genetic Resources, 2021
Using local resources for ruminant feeding is a way to achieve agroecological production in pastoral farming systems. In North Mediterranean countries, sheep farming systems have evolved towards more intensive systems in lowland and hilly areas, whereas

Farmers using local livestock biodiversity share more than animal genetic resources: Indications from a workshop with farmers who use local breeds

Genetic Resources, 2022
Recognizing the products from farms that use local breeds is key to in situ conservation of local animal biodiversity. Recognition often focuses on a small number of specific breeds or products but could be expanded to include multiple local breeds and ...

A Search for Eurasian Sheep Relationships: Genomic Assessment of the Autochthonous Sheep Breeds in Russia and the Persian Plateau

Diversity, 2022
Genomic assessment of local sheep breeds is relevant to the reconstruction of post-domestication migrations and to filling in gaps in the developmental history and contemporary phylogeographic-differentiation patterns in Eurasia.

Development of lymphocyte subpopulations in local breed chickens [PDF]

Veterinary World, 2021
Background and Aim: Local breeds of chicken are known to have relatively higher disease resistance to many endemic diseases and diseases that are highly virulent in commercial chickens. This study aimed to address the lymphocyte subpopulations in three constitutive immune system organs (thymus, bursa of Fabricius, and spleen) in 30, 8-week-old, male ...

Crossbreeding to improve local chicken breeds: predicting growth performance of the crosses using the Gompertz model and estimated heterosis

Poultry Science, 2023
The present study aims to validate the Gompertz model to predict the growth performance of chicken crosses according to growth curve parameters of the parental lines and the estimated heterosis for each curve parameter.

Identifying and profiling the microRNAs associated with skin colour in the Muchuan black-bone chicken

Italian Journal of Animal Science, 2020
MicroRNAs (miRNAs) are an abundant class of small non-protein-coding RNAs that regulate gene expression in plants and animals. Skin colour is an important economic consideration in chicken production, and chickens with black skin have high market value ...
