“…However, some farms are located in temperate zones to meet the demand for raw milk. Our previous study conducted in temperate zone quantified the effect of heat stress on productivity such as 305-milk yield and days open [21]. However, to our knowledge, the effect of seasonality on prevalence and incidence rate of disease has not been investigated in farms located in temperate climate zone.…”

Background Our aim was to investigate the incidence and prevalence of clinical mastitis, peracute mastitis, metabolic disorders, and peripartum disorders, and to examine factors affecting the prevalence of each disease in cows raised on a large dairy farm in a temperate climate in Japan. The present study was performed on a large commercial dairy farm with approximately 2500 Holstein cows. Data were collected from 2014 to 2018, and involved 9663 calving records for 4256 cows. Results The incidence rate on the farm was 21.9% for clinical mastitis, 10.4% for peracute mastitis, 2.9% for metabolic disorders, and 3.2% for peripartum disorders. The prevalence rates for clinical mastitis, peracute mastitis, metabolic disorders, and peripartum disorders were 28.0, 13.3, 3.7, and 4.0%, respectively. In all four diseases, the probability of time to occurrence for each disease was associated with parity and calving season (P < 0.05). Regarding metabolic disorders and peripartum disorders, the probability of occurrence decreased during the first 10 days after calving. Conclusions Our results showed that clinical mastitis occurred most often in this temperate zone, and that metabolic disorders and peripartum disorders occurred from calving to day 10 post-calving.

“…The developed technology can affect most parameters of the microclimate and maintain within the specified limits temperature and relative humidity of air, air velocity, concentration of harmful gases (ammonia, carbon dioxide, and hydrogen sulfide), dust and microorganisms [3,4,6,7,8,10,12,14,15,19]. The technological process of a microclimate system with air conditioning includes such operations as heating, cooling, humidification, drying and purification of air from harmful gases, dust and microorganisms.…”

“…The amount of metabolic energy yielding products other than the body's heat production is also reduced by so-called non-productive energy needs: the energy needs of the animal, consisting of thermoregulation, which is necessary to maintain constant body temperature, and the energy expended on movement [4, 6,12,14,19].…”

The article is devoted to the topical problem of rational use of energy and nutrient content of feed in obtaining livestock products (milk) from cows by shifting the energy balance of the animal’s body towards “productive energy”, i.e. the synthesis of fat and proteins. The authors would like to point out that one of the main factors influencing fluctuations in the energy balance of an animal are microclimate parameters, as the deviation of the microclimate parameters from the established optimal limits leads to a reduction in milk yields by 10 to 20%. Therefore, the aim of our work is to develop an energy-saving technology for the formation of optimal microclimate in livestock facilities using air conditioning systems, which can regulate most of the parameters of the microclimate inside them, namely: temperature, relative humidity and internal air velocity, concentration of harmful gases (carbon dioxide, ammonia, and hydrogen sulfide), dust and microorganisms. The presence of the mode enabling recirculation air purification allows to save heat energy and energy coming with feed by up to 50% compared with typical microclimate systems. To this end, we have systematized separate data from scientific researches done by various scientists in the fields of animal hygiene and veterinary medicine and obtained dependencies of influence of microclimate parameters (temperature, relative humidity, internal air velocity) on the productivity of animals (cows) and feed consumption.
