The classification and regression tree (CART) method produced good models for predicting albumen weight, with R2 values of 0.94 and 0.96, and yolk weight, with R2 values of 0.93 and 0.92, in Potchefstroom Koekoek and Lohmann Brown layers, respectively. This study suggests that a CART data mining algorithm might assist in determining the breed standards of Lohmann Brown and Potchefstroom Koekoek chicken breeds.

We investigate the association between single-nucleotide polymorphisms of RING finger protein 34 (RNF34) and RING finger protein 128 (RNF128) with carcass and meat quality traits. Statistical analysis showed that RNF34 (3′ UTR-588 G>A) and RNF128 (I1-2380C>T) are significantly associated with testis weight, kidney weight, tare weight, dressed weight, forepaw weight, carcass depth, carcass brisket depth, and hind leg length (P<0.05), influencing meat yield and quality.

Genetic variability and selection signatures were analyzed in Anatolian Merino via 351.539 bi-allelic single nucleotide polymorphisms. Adequate genetic diversity with a low inbreeding coefficient was detected. Effective population size, however, showed a declining trend through generations. Selection signals were observed in 37 and 72 protein-coding genes via two statistical approaches; a large part of them were associated with milk traits and udder morphology.

This study examined genetic changes in body measurements at birth in Turkish Arabian foals born between 1987 and 2007. Significant factors influencing body size traits were identified. Additive genetic and maternal heritabilities varied, highlighting their impacts on foal traits. Results suggest the potential for selective breeding to enhance these traits over time, aiding future breeding strategies in Turkish Arabian horses.

The LEP gene has been extensively studied in cattle, but research on goats is limited, often overlooking vital parameters like reproduction and growth. We investigate the relationship between LEP gene polymorphisms and growth or reproductive traits in Saanen goats. Notably, the LEP-Sau3AI SNP exhibited associations with birth weight and average daily weight gain. This pioneering study is the first to explore these traits alongside selected LEP variants in Saanen goats.

This study on Yanbian yellow cattle, known for their quality meat, examined fat from various body regions to understand differences in fat content and gene activity. We found 16 different fats in abdominal tissue, with unique fats in subcutaneous and other tissues. Kidney fat cells were larger than those in other areas. Gene activity varied significantly, with different genes being the most active in various tissues.

DGAT1 influences milk yield and quality. Prior studies had limitations: small sample sizes, no environmental effects, and poor lactation records. Our study of 1104 Holstein Friesian and Jersey cows used polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP) and Sanger sequencing for genotyping. We evaluate genotypic and allelic frequencies, population genetics, and phenotypic effects. Our findings offer more reliable interpretations at both phenotypic and genotypic levels.

The Original Valachian sheep is a Slovak national breed and is well adapted to living in high-altitude pastures. The breed is currently endangered, and there is a lot of interest from breeders in understanding its characteristics, particularly with regards to horn and wool traits. We found specific genes associated with these traits, which can be very important for breeders who are working to preserve this endangered breed.

In this study, genetic bottleneck and migration events among Hair, Honamlı, Kabakulak, and Norduz populations were assessed using 28 highly polymorphic microsatellite loci. No evidence of a genetic bottleneck was detected in Anatolian goats using both quantitative and qualitative approaches. No migration to Norduz was observed, indicating that this breed has become genetically distinct due to geographic isolation. These results may serve to carry out better management practices.

Genetic selection based on bovine casein variants, especially for A2 milk, is a scorching topic in animal breeding and genetics. Our study assessed the genotypic/allelic frequencies, population genetics, diversity parameters, and relationship between genotypes and breeding values with respect to two casein genes, CSN2 and CSN3 in Holstein Friesian cows. The present results are critical for evaluating the genetic merit of cows in commercial dairy cattle breeding.

Litter traits are key indicators of the reproductive productivity of sows. In the present study, four litter traits (total number born, number born alive, piglets born dead, and litter weight born alive) were explored. Several candidate genes were identified by a genome-wide association study and selective sweep analysis. These findings provide novel insights into the genetic basis of pig litter traits and will be helpful for improving molecular breeding in pigs.

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 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.

Short summary
In response to the urgent need for enhancing food security amidst a rapidly growing global population, our study develops new models to improve breeding programs for plants and animals. Traditional models often fall short in capturing the full genetic complexity. However, our three new models demonstrate improved performance by better predicting breeding values, thus supporting more effective breeding strategies and contributing to global food security.
