The Exploitation of Functional Capacity of Robotic Milking Machines in System of Free Moving Animals.
 REICHOVÁ, Sandra
The aim of the thesis was to assess objectively the exploitation of the functional capacity of milking machines in the system of free moving animals. There were data coming from seven agricultural companies analysed in the thesis. The data collection took place from January to November 2009. We were provided with the preliminary data by the individual farms taking part in a programme called T4C. The information on problematic dairy cows comes directly from their breeders. The average production of the dairy cows was the first assessed criterion. The highest production (28.79kg) was achieved by little private agricultural companies. The lowest production (25.22kg) was ascertained in middle-sized companies. As far as the breed of dairy cows is concerned, the Holstein dairy cows gave the highest possible amount of milk (40.43; 30.16 a 27.01 kg). The CRV Fleckvieh cattle dairy cows gave the lowest possible amount of milk (24.83; 21.04 a 22.74 kg). The assessment of the number of milking by means of the robotic milking system represents the next criterion. Little private agricultural companies showed the highest frequency of milking (140.88). Whereas the big agricultural companies showed the lowest frequency of milking (119.28). Mostly the Holstein dairy cows were milked by the robotic milking machines (130.34). On the other hand, the CRV Fleckvieh cattle dairy cows were milked least by the robotic milking machines by contrast (107.94). The middle-sized agricultural companies achieved the highest number of milking per dairy cow, per day (2.47). The little private agricultural companies proved the lowest number of milking per dairy cow (2.34). The mixed herds of the Holsteins and CRV Fleckviehs proved the rate of 2.47. The Holstein dairy cows showed the milking frequency 2.45 per day while the CRV Fleckvieh dairy cows 2.32. The dairy cows from the big agricultural companies went to be milked by the robotic milking machine most frequently from the point of view of willingness, what follows is that these dairy cows showed the highest number of refusals per one milking (2.19). The lowest values of this criterion were shown in little private agricultural companies (1.10). With reference to the breed, the values of this indicator proved the lowest number of refusals (1.85) whereas the CRV Fleckviehs showed the highest number of refusals (2.25). The exploitation of the time capacity has been proven as the most effective one - 78.61% in little private agricultural companies. Whereas the lowest time exploitation has been proven in big agricultural companies - 68.11%. As far as the cow breed is concerned, it was ascertained that the Holstein dairy cows were milked longest -73.21%. On the other hand the CRV Fleckviehs were milked shortest - 63.17%. The highest amount of the dairy cows that needed to by accompanied to the robotic milking machine was recorded in big agricultural companies - 20.1%. Remarkably lower number of problematic cows was ascertained in middle-sized agricultural companies - 9.7%. The number of problematic cows in little private agricultural companies proved to be similar to the number in middle-sized agricultural companies 9.3%. It was ascertained that the most problematic dairy cows came from the mixed herds - 18.7%. The CRV Fleckviehs were the least problematic - 8.8%.
