“…The impact of temperament on milk-related traits based on phenotypic correlation indices proved to be controversial. The milk composition observed in the current study was within the normal range and it was in accordance with results found earlier by Mandal et al, (2016) or Sahu et al, (2018).…”

The objective of the current study was to establish a possible link between cows' reactivity and milk-related traits. In addition, the study intended to examine changes in herd structure related to cow temperament over successive years.Between October 2016 and October 2021, 7600 data were collected from 1520 lactations for milk, fat, and protein yields, as well as milking speed based on cow temperament. The cow's temperament was classified as calm, moderate, and nervous. Most of the cows exhibited moderate reactivity (87.13%) compared to calm (5.24%) and nervous (7.63%). The one-way ANOVA protocol showed that cow's reactivity significantly influenced (p≤0.001) milk, fat and protein yields having more substantial effects (p≤0.001) on the milking speed for nervous ones. The calm cows produced more milk (5766.86±130.98 kg), fat (239.12±5.24 kg) and protein (201.56±4.3 kg) compared to moderate (-309.7, -19.73, -15.3 kg, p≤0.01) and nervous cows (-707.9, -32.2, -28 kg, p≤0.01). Significantly higher milking speed was recorded for calm cows (2.36 kg/min.) compared to moderate (2.28 kg/min., p≤0.05) and nervous cows (2.21 kg/min., p≤0.01). Over successive years a significant increased (p≤0.001) trend in calm (from 3.34 to 8.92%) was observed to the detriment of the nervous cows (from 5.45 to 2.32%) and moderate ones (from 91.21 to 88.76%). The current findings highlight that calmer cows produce more milk, fat and protein yields compared to nervous ones despite the controversial relationship between temperament and milk related traits.

“…It is clear that in our case, the points indicated above (2.5-3.5 m from the floor) will not be informative, which may be related not only to the construction of the building itself (Sahu et al, 2018), but also to those already mentioned above factors (Fregonesi et al, 2007;Morabito et al, 2017;Poteko et al, 2018), as well as animal body position, which can significantly affect airflow distribution (Bustos-Vanegas et al, 2019).…”

“…Insulation of the ceiling under the asbestos roof and the use of sand as bedding in the boxes improved the indoor microclimate. This reduced the heat load on the cows, helped to maintain their normal physiological parameters and increased daily milk-yield (Sahu et al, 2018). It was concluded (Andreasen & Forkman, 2012) that sand had a positive effect on milkyield compared to other stall surfaces.…”

Modern non-insulated barns (NB) for free-stall housing of dairy cows differ from traditional (typical) capital buildings. The formation of the microclimate in such farms is significantly dependent on the state of the environment and their design features. The aim of the work was to give a review of the literature and the results of our own research on creating comfortable conditions for dairy cows in the NB. Our studies indicate the heterogeneity of the microclimate formation in different parts of the NB, which was largely due to the state of the external environment. The use of only natural ventilation through open side curtains and light ridges, as well as additional mechanical ventilation (due to horizontal axial fans) cannot always provide comfortable conditions for animals, especially in hot periods of the year. The literature analysis showed that this can be caused by factors affecting the formation and movement of air masses in the building itself (depending on the number of animals, the condition of the litter, the operation of internal equipment, including space-planning and design features, type and quality of materials of enclosing structures) as well as the weather conditions outside buildings (temperature, humidity, wind strength and also relief). Investigations related to remote methods of microclimate control (using appropriate portable devices) and identification of (critical) control points of deterioration of the air environment in NBs will be promising. Monitoring of them will allow timely to adopt the necessary management decisions for ensuring the comfort of dairy cows in extreme weather conditions. Climate prediction methods based on meteorological data in the area of the NB location and the development of intelligent ventilation systems using mathematical modeling that take into account the behavioral and physiological responses of animals to environmental changes will be especially in demand.

“…According to Brandl (2018), the physiological responses of cattle that can be measured include respiratory frequency, heart rate, body temperature, and a blood profile. The physiological response of cattle can also be measured by measuring the core body temperature of cattle, commonly called rectal temperature (Sahu et al, 2018). According to Suherman et al (2017), the physiological response of cattle increases based on increasing environmental temperature.…”

Cattle is meat-producing livestock of the large ruminant. The environmental conditions must remain in the thermoneutral zone because this affects livestock productivity. An environmental modification related to microclimate management is required through a misting system using a water sprinkler. The study was conducted in one of the barns of the Sekolah Peternakan Rakyat (SPR) Maju Bersama livestock group in Drokilo Village, Kedungadem District, Bojonegoro Regency, East Java. The purpose of this study was to analyze the microclimate management of the barn through the misting system in order to improve the physiological response of cattle. The variables observed were the air temperature, air humidity, Temperature Humidity Index (THI), respiratory frequency, heart rate, rectal temperature, and body surface temperature. Body surface temperatures were measured on the face, back, and rump. The analytical method used in this was unpaired T-test five replications. The results showed that the average microclimate data for barn cattle were: air temperature 27.40±0.59°C, air humidity 83.92±1.55%, and Temperature Humidity Index (THI) 79.59±1.06. The results showed that the average physiological response data for cattle were: heart rate 47.02±2.29 beats per minute, respiration rate 16.94±1.26 beats per minute, and rectal temperature 38.65±0.27°C. The results showed that the average body surface temperature data for the face was 37.03±0.38°C, the back was 36.33±0.59°C, and the rump was 36.28±0.68°C. The results showed that the treatment before and after the morning measurement water misting was significantly different (p<0.05) in all the observed variables. Water misting has the effect on decreasing the air temperature, humidity, Temperature Humidity Index (THI), respiratory rate, heart rate, body temperature, and rectal temperature.
