Genomic variation and population structure detected by single nucleotide polymorphism arrays in Corriedale, Merino and Creole sheep. [PDF]

open access: yes, 2014
THE AIM OF THIS STUDY WAS TO INVESTIGATE THE GENETIC DIVERSITY WITHIN AND AMONG THREE BREEDS OF SHEEP: Corriedale, Merino and Creole. Sheep from the three breeds (Merino n = 110, Corriedale n = 108 and Creole n = 10) were genotyped using the Illumina ...

The level of udder emptying and milk flow stability in Tsigai, Improved Valachian, and Lacaune ewes during machine milking

open access: yesCzech Journal of Animal Science, 2012
The objective of this investigation was to evaluate the stability of milk flow curves and the volume of residual milk in relation to milk flow curves in breeds Tsigai, Improved Valachian, and Lacaune (n = 16 heads per breed) milked twice daily. Milk flow

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

open access: yesFrontiers 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.

Advances in electronics prompt a fresh look at continuous wave (CW) nuclear magnetic resonance (NMR) [PDF]

open access: yes, 2017
Continuous Wave Nuclear Magnetic Resonance (CW-NMR) was a popular method for sample interrogation at the birth of magnetic resonance but has since been overlooked by most in favor of the now more popular pulsed techniques.

Do endangered sheep breeds have an advantage in organic farming? [PDF]

open access: yes, 2006
Endangered breeds are not compulsory for organic farming, but adapted and local breeds are considered suitable for Organic Farming. In the year 2001, 240 ewes of six different breeds were introduced on the experimental farm of the Institute of Organic ...

Transcriptome analyses reveal reduced hepatic lipid synthesis and accumulation in more feed efficient beef cattle [PDF]

open access: yes, 2018
peer-reviewedThe genetic mechanisms controlling residual feed intake (RFI) in beef cattle are still largely unknown. Here we performed whole transcriptome analyses to identify differentially expressed (DE) genes and their functional roles in liver ...

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

open access: yesAnimals, 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.
