Abstract:
Feeding strategy is one of the biggest problems when adopting robot milking technology. This technology is based on attracting the cow to the milking stall by providing concentrates upon visit. In some robot milking dairies, concentrates are also provided by external computer controlled self feeders.
The purpose of this study was to evaluate the optimal concentrates rationing that will attract the cows to the milking stall frequently enough to allow optimal milking frequency.
The work was performed in Hefer dairy that is equipped with 8 milking robots. One robot per group and in each group there is an external computer controlled concentrates self feeder in which the cows can consume the daily ration if they did not consume it in the milking stall. In the treatment groups the rationing of concentrates in the external self feeders was stopped and all the daily concentrates allowance was given through the milking stalls. The milking frequency limitations were lifted in both treatment and control groups. The working hypothesis was that cows in the treatment group will increase their visits to the milking stall hence increase milking frequency that will increase milk production.
As expected the treatment cows did increase their visits to the milking robot and milking frequency was increased resulting in a small increase in milk production. However, the treatment cows could not consume the full daily concentrates allowance in the milking robot and the increase in production is related also to higher food consumption in the common feeding trough.
The trial was performed for another year when switching the groups. The treatment group was now control receiving the daily concentrates ration in both milking stall and external feeders, while the control group became treatment receiving the daily ration only in the milking stall. The results were the same as in the previous year.
We conclude that restricting the concentrates allowance only to the milking stall increases milking frequency, but under the conditions of this particular dairy it is impossible for the cows to consume more than 6 kg concentrates a day in the milking stall.
