Genomic insight into the influence of selection, crossbreeding, and geography on population structure in poultry

open access: yesGenetics Selection Evolution, 2023
Background In poultry, the population structure of local breeds is usually complex mainly due to unrecorded breeding. Local chicken breeds offer an interesting proxy to understand the complexity of population structure in the context of human-mediated ...

Board Invited Review: Crossbreeding beef × dairy cattle for the modern beef production system

open access: yesTranslational Animal Science, 2022
Current trends in the United States dairy industry suggest that crossbred beef × dairy calves are replacing a proportion of the calf-fed Holstein steers slaughtered for beef each year.

Breed of origin of alleles and genomic predictions for crossbred dairy cows

open access: yesGenetics Selection Evolution, 2021
Background In dairy cattle, genomic selection has been implemented successfully for purebred populations, but, to date, genomic estimated breeding values (GEBV) for crossbred cows are rarely available, although they are valuable for rotational ...

Breeding Strategy Shapes the Composition of Bacterial Communities in Female Nile Tilapia Reared in a Recirculating Aquaculture System

open access: yesFrontiers in Microbiology, 2021
In industrial animal production, breeding strategies are essential to produce offspring of better quality and vitality. It is also known that host microbiome has a bearing on its health.

Genetic consequences of terminal crossbreeding, genomic test, sexed semen, and beef semen in dairy herds.

open access: yesJournal of Dairy Science, 2021
The development of breeding tools, such as genomic selection and sexed semen, has progressed rapidly in dairy cattle breeding during the past decades. In combination with beef semen, these tools are adopted increasingly at herd level. Dairy crossbreeding

Terminal Crossbreeding of Murciano-Granadina Goats to Boer Bucks: Effects on Reproductive Performance of Goats and Growth of Kids in Artificial Rearing

open access: yesAnimals, 2021
Simple Summary The Murciano-Granadina is one of the main goat breeds dedicated to milk production worldwide. However, kids of this breed are born with low birth weight and do not grow rapidly, so farmers have little interest in raising them for meat ...

Milk, Fertility and Udder Health Performance of Purebred Holstein and Three-Breed Rotational Crossbred Cows within French Farms: Insights on the Benefits of Functional Diversity

open access: yesAnimals, 2021
Using three-breed rotational crossbreeding in a purebred Holstein (HO) herd raises two questions: Do the different genetic classes of cows generated by crossbreeding perform differently?

Genomic analyses provide insights into breed-of-origin effects from purebreds on three-way crossbred pigs [PDF]

open access: yesPeerJ, 2019
Crossbreeding is widely used aimed at improving crossbred performance for poultry and livestock. Alleles that are specific to different purebreds will yield a large number of heterozygous single-nucleotide polymorphisms (SNPs) in crossbred individuals ...

Smallholder experiences with dairy cattle crossbreeding in the tropics: from introduction to impact

open access: yesAnimal, 2015
Crossbreeding of indigenous tropical and improved western dairy cattle breeds as tool to improve dairy cattle performance on smallholder farms has been widely advocated, criticised and yet applied. The government of Ethiopia supported this technology for

Comparative study of lactation curves and milk quality in Holstein versus Swedish Red and White-Holstein Cross Cows [PDF]

open access: yes, 2018
The objective of this study reported in this research paper was to compare the lactation curves of the production of milk, fat, protein, percentages of fat and protein, and somatic cell score in purebred Holstein (H) cows and Swedish Red and White (SRW) -
