“…In their opinion, it is good if animals recognize each other, then they can use AMS without stress. Barman et al (2017) emphasize that the presence of cows in an unknown group exposes their body to stress, which results in a decrease in milk yield and weight loss. Perhaps, it is not possible to provide a universal and optimal number of cows per robot, and this number is best adjusted individually to each herd.…”

The aim of this study was to compare selected parameters of automatic milking in various European Union countries and United States recorded between 2018 and 2020. Statistical analysis showed highly significant effect of country on all tested milking parameters. It was noted that i.e. the average number of cows per one robot, depending on country, ranged between 51.49 (the Netherlands) and 60.03 (Germany). Cows were milked on the average 2.50 (France) -2.83 (Latvia) per day, with milking speed ranging from 2.30 kg/min (Lithuania) to 2.99 kg/min (US). Daily milk yield obtained from one cow ranged from 25.12 kg (Lithuania) to 34.11 kg (US), while milk efficiency from 1.44 (Lithuania) to 1.77 kg/min (US). Results also showed that the daily milk yield from one robot ranged from 1 351 kg (Latvia) to 1 930 kg (US). The statistical differences between the milking parameters in the compared countries may be the result of the diversified genetic potential of milked cows and the diversity of the feed base.

<b>The aim of the study was to use evolutionary operations (EVOP) to evaluate changes in the behaviour of dairy cows depending on the strategy according to which they were grouped after calving. The experiment was carried out on a Danish farm keeping about 200 Holstein cows. The farm had two separate areas for lactating cows: a small area with 54 waterbeds and a larger area with 133 beds with mattresses. During the experiment both areas were filled with cows. Cows after calving were introduced to either the small area (group) or the large area (group). After 14 days, the cows from the small group were transferred to the large group. The impact of different cow grouping strategies on their lying time, considered a welfare indicator, was examined. During the 210-day experiment, 195,703 observations were collected. The behavioural data were analysed using a linear mixed-effect regression model fitted by the maximum likelihood method. Days in milk, parity number, and lying time of herd mates were found to significantly affect the lying time of individual cows, while the strategy of cow grouping after calving had no effect on lying time.</b>
