Reproductive Diseases Are Key Determinants Influencing the Success of Embryo Transfer and Fixed-Time Artificial Insemination in Cattle [PDF]

open access: yesAnimals
Reproductive biotechnologies, such as embryo transfer (ET) and fixed-time artificial insemination (FTAI), are increasingly adopted to enhance genetic progress in tropical cattle production systems.

Indigenous domestic breeds as reservoirs of genetic diversity: the Argentinean Creole cattle

open access: yesAnimal Genetics, 2001
Contrary to highly selected commercial breeds, indigenous domestic breeds are composed of semi‐wild or feral populations subjected to reduced levels of artificial selection. As a consequence, many of these breeds have become locally adapted to a wide range of environments, showing high levels of phenotypic variability and increased fitness under ...

Genetic Characterization of Argentine and Bolivian Creole Cattle Breeds Assessed through Microsatellites [PDF]

open access: yesJournal of Heredity, 2006
In the present report, the polymorphisms from 9 microsatellites were used to assess genetic diversity and relationships in 4 Creole cattle breeds from Argentina and Bolivia, 4 European taurine breeds, and 2 American zebu populations. The Creole populations display a relatively high level of genetic variation as estimated by allelic diversity and ...

Polymorphism of locus DRB3.2 in populations of Creole Cattle from Northern Mexico

open access: yesGenetics and Molecular Biology, 2008
The polymorphism of locus BoLA-DRB3.2 of the Major Histocompatibility Complex was evaluated in two northern Mexican Creole cattle populations, Chihuahua (n = 47) and Tamaulipas (n = 51). The BoLA-DRB3.2 locus was typed by amplification and digestion with

Patagonian Argentine Creole cattle polymorphism: comparison with North-West populations of this breed

open access: yesResearch in Veterinary Science, 2003
The relict Patagonian Argentine Creole cattle population consist of a small feral population (Los Glaciares population) that is geographically isolated in the South-West of Patagonia. In order to determine the level of genetic variability of this population, the polymorphism of eight structural genes and two microsatellites loci were studied using the ...

The genetic ancestry of American Creole cattle inferred from uniparental and autosomal genetic markers. [PDF]

open access: yesSci Rep, 2019
Cattle imported from the Iberian Peninsula spread throughout America in the early years of discovery and colonization to originate Creole breeds, which adapted to a wide diversity of environments and later received influences from other origins ...

Genetic Diversity of the Beta-Casein Gene in Brown Swiss and Creole Cattle From the Peruvian Highlands. [PDF]

open access: yesAnim Genet
ABSTRACT Cattle's milk and derivatives are essential for human nutrition. However, up to 90% of people experience gastrointestinal discomfort after consumption. Milk digestibility depends on its protein composition. Casein, about 80% of milk proteins, includes beta‐casein (CSN2) with two variants: A1 and A2. The A1 variant is linked to gastrointestinal

Comparative analysis of PRNP 12-bp and 23-bp indels in healthy Aberdeen Angus, Aberdeen Angus x Hereford, Holstein Friesian and Uruguayan Creole cattle [PDF]

open access: yesPesquisa Veterinária Brasileira, 2023
: Bovine spongiform encephalopathy (BSE) is a transmissible progressive neurodegenerative disease characterized by the accumulation of a pathological isoform (PrpSC) of the cellular prion protein (PrpC) in the brain of cattle.

Non-Linear Mixed Models for the Characterization of Growth Trajectory Measured by Ultrasound of 'San Pedreño' Creole Pig Breed From Colombia. [PDF]

open access: yesVet Med Sci
Using real‐time ultrasound images taken in vivo, the thickness of back fat and the longissimus dorsi muscle width can be estimated in ‘San Pedreño’ Creole pigs. ABSTRACT The aim was to identify non‐linear regression models, under the context of mixed models, to describe the growth trajectory of ‘San Pedreño’ Creole pigs based on two muscular ...

Zoometric Characterization of Creole Cows from the Southern Amazon Region of Peru

open access: yesDiversity, 2021
Bovine breeding began in Peru more than five centuries ago; since then, adaptation has started. Nowadays, Creole cattle are part of economic activities of Peruvian farmers, as they supply food and profits, among other things, for families in Andean ...
