<![CDATA[Beta-lactoglobulin genetics is one of the whey proteins in cow's milk that can influence improvements in milk composition, production, and component levels. Reproductive disorders and clinical mastitis in livestock are often related to genetic, hormonal, and environmental factors. Research on the relationship between beta-lactoglobulin and cow reproduction is still very limited. Therefore, the aim of this study is to determine the relationship between beta-lactoglobulin genotype and clinical mastitis as well as reproductive disorders (dystocia, retained placenta, and endometritis). This research utilizes secondary data obtained from the KPBS Pangalengan headquarters, consisting of genotype examination results of betalactoglobulin and medical records of cows experiencing clinical mastitis and reproductive disorders. A total of 113 samples were collected. The data were analyzed using quantitative methods, followed by ChiSquare tests using Microsoft Excel and SPSS version 25.0 for data analysis. The results showed that the beta-lactoglobulin genotype was not associated with the incidence of clinical mastitis (p=0.509) or reproductive disorders such as dystocia (p=0.789), retained placenta (p=0.193), and endometritis (p=0.685). All test results indicated significance values ≥0.05. The conclusion of this study is that polymorphism beta-lactoglobulin does not have a significant relationship with clinical mastitis and reproductive disorders occurring in Friesian Holstein cows at Pangalengan area. Keywords: beta-lactoglobulin, clinical mastitis, dystocia, endometritis, Friesian Holstein cow, retained placenta.]]>
