Milk production after breeding system change and the introduction of robotic milking

Čeprav je sistem molže z robotom podoben običajnim sistemom molže, obstajajo med njimi velike razlike. Zato smo se na praktičnem primeru odločili raziskati vpliv spremembe načina reje in molže na prirejo mleka. Na kmetiji Vrzel so novembra 2013 pričeli uporabljati molzni robot. Pridobili smo podatke s Centralno podatkovne zbirke za tri obdobja (vmesno obdobje, obdobje pred in obdobje po uvedbi molznega robota). Opazovano obdobje je zajemalo podatke o povprečni mlečnosti, vsebnosti maščob, beljakovin, laktoze in skupnemu številu somatskih celic v mleku na dan kontrole. Podatke smo obdelali s statističnim programom SAS. Za primerjavo parametrov je bila narejena analiza variance ANOVA. Za primerjavo skupnega števila somatskih celic v mleku je bila narejena analiza na logaritmiranih vrednostih. Pri količini namolzenega mleka ni bilo opaženih signifikantnih razlik. Analiza zajetih podatkov pa je pokazala signifikantne razlike pri parametrih. Vsebnosti maščobe, beljakovin in laktoze so bile signifikantno višje. Število somatskih celic je bilo po uvedbi molznega robota signifikantno nižje. Uvedba robota je rejca zelo razbremenila. Na kmetiji je sedaj manj težkega fizičnega dela v hlevu, saj ni več ročnega krmljenja in ročne molže, ki sta vzeli največ časa pri opravilih v hlevu. Altough the milking system with a robot is similar to a normal milking system, there are big differences between them. It was therefore decided to present a practical case and the impact of the change in the mode of farming and milking on milk production. The farm Vrzel started using milking robots in november 2013. We recieved the data from a central database for three periods (intermediate period, before and after the introduction of the milking robot). The observed period included data on average milkiness, fat content, protein and lactose in the total number of somatic cells in the milk on the day of control. The data was processed with the statistical program SAS. Significant differences in the quantity of milked milk were not observed. The analysis of the covered data showed significant differences in the parameters. The fat, protein and lactose contents were significantly higher. The number of somatic cells was significantly lower anfter the introduction of the milking robot. The introduction of the milking robot has really relieved the breeder. At the farm, there is less heavy physical work in the barn now, because there is no manual feeding and manual milking, which took up most of the time.
