Abstract:

The objective of the research was to find whether any differences exist between cattle herds operated by certain milking installations. The cattle herds were studied not only by herd size but also by certain data, like annual milk yield, age and number of lactations. Data collected on dairy farms that operate pipeline milking systems, milking parlours and automatic milking systems were analysed. These farms are situated in three Baltic States. The investigated Estonian dairy farms indicated a decreased tendency in the prevalence of disease cases for udder diseases with an increase in cow herd size. An index of cow production potential was proposed to compare different (including number of lactations) group of cows in dairy farms.

Abstract:

The research concerns fodder distribution solutions for cows which are milked using the VMS robotised equipment produced by the company DeLaval. The research is conducted at the milking cow farm ‘Līgotnes’ of the Latvia University of Agriculture study and research farm ‘Vecauce’. In the research, cattle-shed cows receive fodder in three different places: together with the basic feed mixture while eating at the feeding table, in the robotised milking stand and at the fodder feeding stations. The research has stated that this feeding system is rational. Adding fodder to feed mixture (about 10% of its mass) is necessary as it improves the feed mixture taste qualities. Hence, it increases the consumption of this mixture and also the cow yield. If fodder is not added to the mixture, the productivity of highly productive cows deteriorates and can decrease by 10%. Moreover, we can add to basic feed mixture fodder prepared at the farm using the grains grown there. Usually, such fodder is cheaper than the bought one, and therefore decreases the prime cost of the milk. Fodder is also fed also in the robotised cow milking stands as such an approach stimulates cows to visit the milking stands more frequently. But during the research we found that highly productive cows with the yield exceeding 30 kg per day do not manage to eat all the due fodder amount during milking. Therefore, fodder feeding stations are necessary for feeding of highly productive cows. They shall be placed after the sorting gates so that the cows that are not directed to milking by the automatic sorting system could visit the fodder stations. Moreover, the number of fodder feeding stations per one cow milking group should not be less than two.
