Behavior analysis of the dairy cows with technology of milking robot

With the increasing consumption of milk and dairy products the number of dairy cows grew up also. But at the same time the requests on dairy cows were increasing which brought changes in technology and technique of the milking system which would be helpful with milk production, productivity of work and welfare of dairy cows. Milking robots could be a suitable solution. The first robot was installed on a farm in Netherlands in 1992. The aim of the bachelor thesis is to evaluate the basic behavior of Czech Spotted cattle based on analysis of their daily behavior with connection to dairy production and to the number of milking during the lactation. There were three ethological observations realized from June to December 2009 on a private family farm in Chlumeček near Křemže. The whole area of agricultural land is 320ha, out of which 120ha permanent grass and 210ha arable land. On this farm there are 72 dairy cows of Czech Spotted cattle in average, their hybrids and several pieces of Holstein dairy cows. The data were evaluated in the program Microsoft Excel and Statistica 9. The dairy cows gave attention to the feed intake most of all in September and that presents 26.07% of the whole day. It was 23.18% during the first observation in May and for the third observation in December 24.35% of the time. Standing of cows averaged 22.33% and the length of active time reached in average 4.33%. The lying duration of dairy cows were changed minimally during the year. At the first observation the lying period was 49.88%, at the second observation it was 48.25% and at the third observation 48.87% of the time. Quantity of milk per lactation was 4679kg in average; the highest productivity reached the group of dairy cows during the second lactation (4866kg of milk). Quantity of protein was 159.33kg in average with the content of 3.40%. The average number of milking reached 2.86 per day. The length of insemination interval was 103.49 days and service period was 159.97 days
