This study was carried out to estimate variance components using a univariate animal model accounting for maternal effect by the restricted maximum likelihood (REML) method. Some environmental factors affecting body measurements and ultrasound carcass traits in yearling Anatolian buffalo calves were highlighted for the successful selection program. Genetic and phenotypic correlations and selection responses were also revealed in this study.

The aims of this study were to estimate the genetic parameters of test day milk yield in the population of the White Maritza sheep breed and to choose the most appropriate linear models for genetic-parameter estimation of test day milk yield. Nine test day models were formulated and tested for the estimation of genetic parameters of milk yield. To compare the linear models described above, Akaike information criterion, Bayesian information criterion and log-likelihood were calculated.

The current study aims to investigate the genetic diversity of native Algerian rabbit populations at 25 different geographic locations belonging to 7 regions using 85 microsatellite markers. According to the discovered results, high diversity was recorded in the south. In addition, the results noticed a high degree of geographical distribution (east, west, middle, and south). Generally, the current study records a high internal-breeding factor, although the samples were collected randomly.

This paper reports on the genetic diversity parameters of 12 Beninese indigenous guinea fowl phenotypes distributed in three climatic zones. More information has been provided through the results on genetic conservation and adaptability of the phenotypes to the local environment under climate change's continuous impact.

This study is a bibliometric study of animal breeding value. Bibliometric analysis is the widely accepted method for assessing the merits of a specific field. This study provides an excellent guide for further studies by revealing general development trends, hot topics, and research boundaries over the past 20 years. It is possible to say that future studies will focus on innovative issues that may have limited environmental impacts while reducing costs and accelerating livestock productivity.
