The use of milking robots for milking Holstein cows
 BARTŮŇKOVÁ, Ilona
Abstract Robotics technology has been already spread in agriculture especially into livestock production mainly in milking process. The aim of this thesis was comparison of the production results of Holstein cows housed in different conditions. The first group of monitored cows was housed in a loos housing with free strawed stalls and milked at milking parlour. The other group was housed in a reconstructed loos housing with free rubber mattressed stalls and milked with milking robots. There were analysed reproduction parameters and milk efficiency and compared technologic and labour intensity. Data were collected and evaluated in 2010. As reproductive factors in a group of selected cows (31 animals respectively 34 animals) were analysed the length of service period and length of the interval between calving. Service period of cows milked in the milking parlour was for the first lactation cows 94.8 days and for the second lactation 100.3 days, the average length of the interval between calving was 374.6 days. By the second group of cows milked by robots were the length of service period 88.3 days for first lactation cows and for second lactation cows 112.5 days, the interval between calving 373.2 days. By analysing milk production were found out statistically significant differences (P ? 0.001) in amount of produced milk. Both lactation cows milked by milking robots reached higher yield. On the first lactation was increases of 2169.7 kg of milk with an average yield 9130.2 kg of milk. The second lactation cows increased milk yield to 10,555.2 kg of milk, which was 1998.6 kg of milk more in comparison with the amount of milk produced by cows milked at the parlour. In the fat and protein content weren?t found out statistically significant differences between groups. After robot milking was introduced the number of cows per one employee were increase from 32.9 pc to 41.1 pc. The average number of milking per head and the day increased from 2 to 2.3 (some cows are milked 6 times in 24 hours, but it depends on the cow milk production and part of the lactation).
