Genome-Wide SNP Data Revealed the Extent of Linkage Disequilibrium, Persistence of Phase and Effective Population Size in Purebred and Crossbred Buffalo Populations

Frontiers in Genetics, 2019
Linkage disequilibrium (LD) is a useful parameter for guiding the accuracy and power of both genome-wide association studies (GWAS) and genomic selection (GS) among different livestock species. The present study evaluated the extent of LD, persistence of

Genetic Evaluation of Pure Line Laying Hens Based on Crossover Testing Data From Simulated Populations

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Commercial laying hen breeding programs aim to maximize the performance of crossbred animals. However, selection is usually based on data from pure lines raised in controlled nucleus environments, which may not fully predict the yields under commercial conditions.

Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment.

Genetic Parameters for Feed Efficiency Indicator Traits in a Rotational Crossbreed Sow Population During Lactation Period

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The selection of feed efficient sows effectively converting feed into milk production and body weight gain will contribute to the overall profitability of pig farming systems. Consequently, the aim of the present study was to estimate genetic parameters for feed efficiency indicator traits during the sow lactation period, and to infer ...

Heritability of Productive, Reproductive and Carcass Traits in Pure‐Bred and Cross‐Bred Pigs: A Systematic Review and Meta‐Analysis

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Heritability (h2) is a key parameter in animal breeding, but its magnitude and consistency across pure‐bred (PB) and cross‐bred (CB) pig populations remain poorly understood. This study aimed to compare heritability estimates between PB and CB populations for economically relevant traits through a systematic review and meta‐analysis.

Genome‐Wide Association Studies for Anogenital Distance and Linear Type Traits in Gir Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Although linear type traits have been under selection in the Dairy Gir cattle for the past three decades, there are few studies exploring genetic architecture for these traits. The aim of this study was to identify candidate genes for anogenital distance and linear type traits in the Gir breed. For this study, the body measures of rump length (

Evaluating the performance of genomic selection on purebred population by incorporating crossbred data in pigs

Journal of Integrative Agriculture
Genomic selection (GS) has been widely used in livestock, which greatly accelerated the genetic progress of complex traits. The population size was one of the significant factors affecting the prediction accuracy, while it was limited by the purebred ...

Differences in Feeding Management of Pet Rabbits by Owners and Hobby Breeders and Their Impact on Animals' Health: A Survey

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Over the last decades, the population of pet rabbits in Europe has increased significantly, but to date studies into feeding management of these species have been mainly conducted in production animals. This study aimed to evaluate the feeding practices of both pet rabbit owners and hobby breeders in Germany and how these may affect animal ...
