The assessment of the spread of udder diseases in Alpine goats in a large dairy farm was carried out. Also, ultrasound studies of the udder were carried out in order to determine the criteria for the presence of latent mastitis, as well as to determine the DNA of pathogenic and opportunistic microfora in milk samples, as well as the presence of antibiotic resistance genes. Te conducted studies have shown that mastitis is widespread in goats of alpine breed in the conditions of industrial milk production and is mainly registered in the spring-summer period, which is associated with an increase in the number of lambings. At the same time, mastitis is mainly observed in animals of the frst lactation with a tendency to decrease as the number of lactations increases. Te largest percentage of cases is observed in the frst week of the lactation. Also, the level of mastitis increases during the period of decline in milk production afer 201 days of lactation. In 80 % of samples from goats, the presence of DNA of mixed microfora, including bacteria resistant to a number of antimicrobial agents, is noted. The presence of hyperechoic inclusions in the lumen of the milk cistern in goats is not a criterion for the presence of latent mastitis and is observed in goats with a high percentage of fat and protein.
