Genome-Wide Association Study for Reproductive Traits in a Duroc Pig Population

open access: yesAnimals, 2019
In the pig industry, reproductive traits constantly influence the production efficiency. To identify markers and candidate genes underlying porcine reproductive traits, a genome-wide association study (GWAS) was performed in a Duroc pig population.

Genome-wide association study reveals candidate genes for body size and reproductive traits in Hu sheep [PDF]

open access: yesAnimal Bioscience
Objective Larger body size and enhanced reproductive performance are correlated with increased profitability for sheep farmers. Hu sheep have smaller statures compared to other meat sheep breeds, necessitating improvement.

An Appropriate Genetic Approach for Improving Reproductive Traits in Crossbred Thai–Holstein Cattle under Heat Stress Conditions

open access: yesVeterinary Sciences, 2022
Thailand is a tropical country affected by global climate change and has high temperatures and humidity that cause heat stress in livestock. A temperature–humidity index (THI) is required to assess and evaluate heat stress levels in livestock. One of the

Genetic Features of Reproductive Traits in Bovine and Buffalo: Lessons From Bovine to Buffalo

open access: yesFrontiers in Genetics, 2021
Bovine and buffalo are important livestock species that have contributed to human lives for more than 1000 years. Improving fertility is very important to reduce the cost of production.

Reproductive trait differences drive offspring production in urban cavity‐nesting bees and wasps

open access: yesEcology and Evolution, 2021
The contrasting and idiosyncratic changes in biodiversity that have been documented across urbanization gradients call for a more mechanistic understanding of urban community assembly. The reproductive success of organisms in cities should underpin their

Evidence for reproductive senescence across ray-finned fishes: A review

open access: yesFrontiers in Ecology and Evolution, 2022
The origin, incidence, and consequences of reproductive senescence vary greatly across the tree of life. In vertebrates, research on reproductive senescence has been mainly focused on mammals and birds, demonstrating that its variation is largely linked ...

Evaluation of Some Economical Traits of Commercial Friesian Cows Herd Raised in Egypt [PDF]

open access: yesJournal of Animal and Poultry Production, 2020
This study conducted to evaluate some of non-genetic and genetic parameters that affect the productive and reproductive traits. Total of 3596 records of 1021 Holstein Friesian cows in the first five parities were collected during the period from 2002 to ...
