Precision technologies as tool for enabling sustainable dairy farming

Precision dairy farming is one of the central topics that affect global dairy farming. It involves use of technologies for measuring physiological, behavioural and production indicators on single animals. There are several main aims of precision dairy farming, such as 1) maximizing animal performance, 2) early detecting diseases in individual cows, 3) early detecting herd level health and production problems, as well as 4) minimizing the use of medication through preventive health measures. Examples of precision dairy farming technologies are: milk yield recording systems, milk component monitors, milk conductivity indicators, activity monitors, lying and rumination behaviour monitors, and heat detection monitors are examples of precision dairy farming technologies. During the milk recording, milk production traits are recorded which represent significant information for managing and breeding of dairy herds. During the milk recording, milk production characteristics are recorded which represent meaningful data for control and breeding of dairy herds. This is also an ideal way for farmers to track their best and worst animals. Therefore, farmers can make management decisions and do the selection. Moreover, milk recording data provide an evaluation of the influence of a dairy farm on environmental pollution. The aim of this research was to determine the variability of daily milk lactose content and somatic cell count and consequently ammonium emission in Holstein first parity cows in Eastern Croatia depending on the season based on the results of milk recording that is using the precision dairy cattle technologies. The preparation of database, logical control of data, as well as statistical analysis was performed using SAS/STAT.
