Genetic Determination of Maternal Behaviour in Pigs

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

Semen Characteristics of Purebred and Crossbred Male Rabbits

PLOS ONE, 2015
Le but de cette enquête était d'évaluer les traits de qualité du sperme des lapins mâles de race pure et de leurs croisements dans des conditions subtropicales égyptiennes. Un croisement complet de 3 x 3 diallèles a été effectué pour produire la première génération de races New Zealand White (N), Flander (F) et Rex (R).

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.

Genome-wide association study for carcass quality traits and growth in purebred and crossbred pigs.

Journal of Animal Science, 2019
Carcass quality traits such as backfat (BF), loin depth (LD), and average daily gain (ADG) are of extreme economic importance for the swine industry. This study aimed to: i) estimate the genetic parameters for such traits and ii) conduct a single-step ...

Breeding Values, Accuracies, and Rank Changes Using Purebred and Combined Purebred and Crossbred Information in Swine

The Professional Animal Scientist, 2006
A data set including 2,002 purebred litter records and 14,583 crossbred litter records from a swine production unit with a defined great-grandparent (GGP), grandparent, and parent stock genetic system structure was used to examine the gains in accuracy of breeding value estimation of the purebred GGP animals through inclusion of crossbred information ...

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 ...

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 ...

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.
