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.

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.

We measured physical meat quality of a slow-growing broiler as an alternative to fast-growing broiler, and we used slatted floor housing and free-range production as alternatives to conventional deep litter. Taking into account genotype × housing system interactions for meat pH and shear force traits, a fast-growing broiler may be more appropriate for fully slated housing and a slow-growing broiler may be more suitable for a free-range housing system.

An extensive genetic evaluation of cattle fattening performance was performed in this study. Fifteen SNPs in the LEP, FABP4, DGAT1, TG, IGF1, IGF1R, MYF5, LGB, CAPN1, CAST, GHR, and OLR1 genes were evaluated in 296 purebred Holstein–Friesian bulls using PCR-RFLP. This study clearly demonstrated that individual or combined effects of the genotypes at the selected genes may be effective on performance traits at different periods of animal growth and fattening.

The impact of polymorphisms of the calpain 1 (CAPN1), calpastatin (CAST), leptin (LEP) and growth hormone receptor (GHR) on carcass characteristics and meat quality traits in 400 purebred Holstein bulls was examined using polymerase chain reaction and restriction fragment length polymorphism method. In the current study, the CAPN1, CAST and GHR genotypes confirmed significant associations with important traits in adequate numbers of animals.

The present study was based on the association of polymorphisms at LEP, CAST, CAPN1, GHR, FABP4 and DGAT1 genes with fattening performance and carcass traits in Simmental bulls. Results indicated that final weight, fattening period, total weight gain and average daily gain differentiated the CAST and CAPN1 marker genotypes. Moreover, a novel effect of the LEP A80V on carcass weight and dressing percentage was observed. The results could be indicative for future studies on beef production.

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.

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.

This study examines the crossbreeding of Indonesian local rabbits with imported breeds, highlighting the heterosis effects. Crossbred rabbits, especially Rex descendants, show notable growth benefits. Based on the results, we advocate for strategic crossbreeding to enhance rabbit growth and offer insights into sustainable rabbit production.

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
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.
