Application of Lacto-Corder in the control of production and milkability properties of dairy cows in Croatia

Control of dairy cows production in Croatia consist of two steps: measurement of milk amount after milking and taking of milk samples for chemical analysis. This kind of control gives very few information about production. On the other hand, for several years other countries use sophisticated devices, such as Lacto-Corder, for monitoring of many parameters important for production and selection of cows. Lacto-Corder is measuring device for production control and collecting of milk samples. It is acknowledged by the International Committee for Animal Recording (ICAR). In Croatia, for the research work and investigation of use in production, first Lacto-Corder was bought. Research work was conducted on Holstein cows (n=457). Cows were in the range from first to sixth lactation. Thirteen production parameters were measured. Duration of main milking phase (tMHG) was 4.51 min. The average amount of milk in that time (MHG) was 10.18 kg. Average milking in minute (DMHG) was 2.27 kg/min. Research results have showed justifiability of using Lacto-Corder in every day production control of dairy cows in Croatia. Amount of information and their precision for every examined animal were manifold higher. Only obstacle for use of Lacto-Corder in Croatia today is very high selling price.
