Technology of milking with milking robot in relationship to dairy welfare
KOUTEK, Martin
The theme of this bachelor thesis is focused on evaluation of influence of milking technology by milk machine on welfare milk cow. Ethologic displays of milk cows after milking and various parameters related to milking were found out. The main parameters were the amount of attempts to place teat-cups, the time from milk cow?s entering into the robot to successful placing all four teat-cups, the whole time of milking and the time between every single milking. Further, the need of fluid and food intake and lying down in the 30 minutes after milking were observed during the ethologic observation. At the end of the observation the state of health of milk cows with focus on mammary gland illnesses was assessed. Ethologic observations took place twice, always last 24 hours and the results were compared with the order of milk cow?s lactation and with every single observation. Part of the data were gain during the observation itself and part from the milk machine?s database. During both observations the average amount of attempts to place teat-cups was detected as about 1.6 per one milking. The average time from milk cow?s entering into the box to placing teat-cups was 2 minutes and 18 seconds. The whole time of milking per 24 hours was 12 hours and 37 minutes during the first observation and 11 hours and 48 minutes during the second observation. The time between milking was on average 11.5 hours when milking twice a day and about three hours when milking three times a day. As far as the activity in the 30 minutes after the milking is concerned, milk cows had similar habits, bigger difference was in fluid intake both from the viewpoint of every single observation and from the viewpoint of the order of milk cow?s lactation as well. The need of food intake was on average at 84 % of observed milk cows, the need of fluid intake was on average at 37 % of observed milk cows and the need of lying down was at 7 % of observed milk cows. The amount of mammary gland illnesses was at a low level. During the observations was found out that the using of milking machines has positive influence on welfare milk cows. Milk cows had permanent access to water and food, in the stable was quality climate, the amount of mammary gland illnesses was negligible. Milk cows had enough of space and were calm because they did all activities during the day wholly voluntarily.
