“…It should be borne in mind that the lactation reflex may be inhibited or not manifested because of sharp noises and brutal treatment of cows. In such cases, the endocrine glands secrete the hormone adrenaline, which sharply narrows the milk ducts and delays the secretion and movement of oxytocin, as a result of which the cow 'does not entirely let down' milk (Gross & Bruckmaier, 2019;Palii et al, 2020g).…”

Improving modern dairy farming is based on the industry's development, which means transforming livestock farming into a competitive industry. The development of its technical and technological support is closely related to its functional ability to realize the genetic potential of biological objects of production with high-quality products, which is the defining criterion for the competitiveness of machinery and technology at the industry’s present stage of development. The purpose of the research was to study milk production technology based on a comprehensive assessment and implementation of modern milking equipment, maximizing animals’ genetic potential and industry efficiency. We proved that applying the ‘DeLaval’ milking parlor under the same feeding and keeping animals ensured the proper completeness of milking and increased cows’ milk yield. During the first, third, and highest lactations, the milk yield was 226 kg (P=0.05), 266 kg (P=0.05), and 214 kg (P=0.05), respectively. After-milking when applying ADM-8A averaged 175 ml, and only 45 ml when applying the ‘DeLaval’ parlor. When using the ‘DeLaval’ milking equipment, the milk production intensity of cows was 1.43 kg/min, and, with ADM-8A, it was 1.24 kg/min, which is 0.19 kg/min (P=0.001), or 15.3% higher.

“…Although Ladyka (1999) and Ovcharenko (2000) have determined that an increase in the proportion of heredity of the improving Holstein breed has a positive effect on milk's average protein content and its qualitative composition, until now, scientists have obtained the results of the influence of several factors (genetic and non-genetic) on the change in the protein content in milk of cows in previously created breeds (Palii et al, 2020f). A comparative assessment of the results of these studies indicates their diversity.…”

One of the main factors in increasing the efficiency of milk production is the breed. No breed in the world would be ideal for a variety of conditions and technological processes. Besides, like any biological system, the breed is in continuous change. The breed of cattle largely determines both the level of milk production and the quality of milk. Therefore, to improve the quality of milk, it is necessary to establish the degree of influence of zootechnical and technological factors on the condition of milk components. Among genetic factors, the breed of animals and the breed combination have a significant influence. During the research, a one-way analysis of variance of the breed's influence and breed combinations on productive indicators has been analyzed. The factor "breed" and "breed combination" were used as the analyzed factor, and the protein content in milk and the yield of milk protein was used as the dependent factor. Based on one-way and multi-way ANOVA, the degree of influence of the factors under study was assessed. It has been established that the breed has a significant, both direct and combined with other factors, influence on the protein content in milk and the yield of milk protein. The level of the breed's direct influence on the protein content is 1.0%, on the milk protein yield - 1.7%. The factors "father" and "calving number" have the most substantial combined effect. Their influence levels are 1.8%, 1.4%, respectively, with a high level of reliability (P=0.999). The same factors most influence the milk protein yield as the protein content (the levels of influence are 1.9%, 1.3%, respectively) with a high level of reliability (P=0.999). As a result of analyzing the data on changes in protein content and milk protein yield in cows of different breed combinations, it can be concluded that this factor can describe 4.5% of the variability in protein content and 11.4% of milk protein yield (P=0.999). The degree of joint influence of breed combinations with other studied factors was up to 6.6%.

“…Escherichia coli strains were resistant to ofloxacin in more than 95.0% of cases (Kasianchuk et al, 2018). Studies of antibiotic resistance of strains from the udder of cows with mastitis suggested that long presence of yeast cultures in the microbiocenosis together with E. coli cultures increases the antibiotic resistance of the latter (Kalashnikov, 2011), while in about 30.0% of cows with mastitis, E. coli was isolated from milk (Palii et al, 2020).…”

In Ukraine zoonoses are a permanent threat to human health, some of them are bacterial diseases associated with farm animals. Complete avoidance of outbreaks of bacterial zoonoses is not possible but it is appropriate to study them to reduce the risks of transmission of zoonosis pathogens from industrial farms to the human population and the environment. The article highlights the results of a literature review on the potential role of industrial livestock farms in the spread of major bacterial zoonoses in Ukraine. About half of all of the country’s farmed animals are kept on farms using industrial technology; more than half of the establishments are classified as medium and large. The technology of keeping animals on such farms contributes to the development of diseases of obligate hosts caused by fecal bacteria. The systematic search and selection of literary sources, which are relevant to the topic of the study were carried out. The vast majority of analyzed publications are published in Ukrainian in local peer-reviewed scientific journals. An analysis of open-access official statistics from the state authorities of Ukraine was also conducted. The authors analyzed statistics and scientific papers published over the last 10–15 years discussing the outbreaks of food-borne zoonoses among humans and the studying their pathogens (Campylobacter spp., Salmonella spp., Escherichia coli (STEC strains), Listeria spp.) on industrial livestock farms. The main source of Campylobacter spp. and Salmonella spp. distribution are industrial poultry, including broilers and chickens, respectively. The STEC strains E. coli carriers are various types of farm animals, including cattle and pigs. The majority of infections documented in Ukraine are cases of salmonellosis in humans and animals. Despite reports of a significant prevalence of campylobacteriosis, colibacillosis and listeriosis in livestock farms, their association with outbreaks of food-borne zoonoses in humans remains poorly understood. The concept of an industrial livestock farm involves a permanent presence of a risk of outbreaks of bacterial zoonoses and their rapid spreading to the human population. This is due to concentrated maintenance of animals, standardized feeding, the priority of achieving the highest productivity of animals and economic indicators. Under such conditions, disturbance of hygienic norms and technologies significantly increases the risk of bacterial zoonoses on industrial farms. It is important to enforce the continuous control of the level of microbial pollution of farms, animal health, hygiene of milk production and processing, meat, eggs, etc. Farms have a negative impact on the ecological welfare of the surrounding territories. The problem of spread of antibiotic-resistant strains of bacterial zoonoses is a very serious one. Efforts for the formation of a national system of epidemiological supervision over bacterial zoonoses, comprising epidemiological, epizootological, ecological, microbiological, serological and molecular genetic monitoring, as well as the development on this basis of effective prophylactic and anti-epidemic measures are relevant and necessary.
