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.

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.

This study investigated the extent to which genetic factors contribute to variations in body weight among Anatolian buffalo calves from birth to 12 months of age. Utilizing data collected from multiple farms in the Istanbul region, the analysis revealed that genetic influence on growth traits is substantial. The results indicate that selection based on estimated genetic merit could effectively enhance growth performance in Anatolian buffalo populations.

This study aimed to reveal the effects of birth weight (BW), 6-month live weight (LW6), and 12-month LW (LW12) on the first lactation milk yield and reproduction characteristics and to determine the non-genetic factors affecting these traits of Anatolian buffaloes in Amasya Province. The effect of growth traits on the first calving age (FCA) of the LW12 group was significant (P = 0.036).

This study aimed to detect a potential association between GHR/AluI polymorphism and milk yield and milk composition traits in dairy cows raised in commercial herds using the PCR-RFLP assay. In conclusion, the GHR gene should be regarded as potential candidate genes in marker-assisted selection programs to improve the performance of milk and related traits in Turkey dairy cattle populations.

Short summary
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.
