“…The consequence of increased number of services per conception among multiparous was the longer service period (by 21 days) in comparison with the heifer group. Marsalek, Zedníkova, and Voriskova () observed a significant correlation (0.309) between the service period and calving to conception period. The length of pregnancy was similar in all researched animal groups.…”

The objective of the research was the evaluation of change in the traditional milking system using automatic milking system in the scope of the selected reproduction features of dairy cows of the Polish Holstein-Friesian breed. Animal material consisted of 2,818 cows used on nine farms equipped with the automatic milking system Astronaut A4 made by Lely. The cows were controlled in the scope of services per conception, service period, length of pregnancy, calving interval and calving to conception period, milk yield, protein and fat content obtained in lactations of 305 days. The selected traits were observed between 2005 and 2015. In this period, the milking system was changed from the conventional to automated one. The collected data material was statistically processed, using the multifactorial analysis of variance. The period between the first calving and the second effective insemination was reduced by 11.8 days, and the period between the second calving and the third effective insemination was shortened by 4 days after the installation of the automatic milking system. The increase in milk yield by 466 kg during 305-day lactation was observed among primiparous cows. The percentage of protein and fat content in the researched groups decreased; moreover, the fall of intergroup variability was noticeable, which may be a sign of the levelling of the yield within the herd.

“…Considering that such cow milking solution was introduced in Latvia, LLU created a research group, which started a detailed study of robotic milking and its comparison with already traditional technologies [3; 4] and similar studies in other countries [5]. Therefore, information was obtained on the frequency of robot visits, the amount of milk milked, the duration of individual milking operations, the effect of power consumption during milking, etc., as well as a number of errors that interfered with the proper progress of the milking process was discovered and eliminated.…”

. Robotic milking of cows began in Latvia in 2007, when it was introduced on two farms, including the training and research farm “Vecauce” of the Latvia University of Biological Sciences and Technology (then the Latvia University of Agriculture). These were the DeLaval VMS robots that are still in use on the farm “Vecauce”. A similar study was carried out already in 2009, but since then DeLaval milking robots have undergone technical and software updates and improvements. Therefore, a comparison of the operation indicators of these robots with the latest model of the same company, VMS V300, was made. Research shows that performing all technical maintenance intended for the VMS robot and replacing the original management system software can ensure successful operation of this robot even after 16 years of use. However, it has difficulties with accurately attaching the milking tubes to the respective cow’s teats. Because of this, the application of tubes is delayed and the average milking time of one cow reaches 8.25 minutes. When milking with the company’s latest generation VMS V300 robot, which uses a 3D camera to connect the milking tubes, the average milking time is only 6.6 minutes. Therefore, we can assume that the robots used on the farm “Vecauce” for milking cows are morally and physically obsolete.
