Abstract:

The aim of this paper is to present the main criteria, which could be used for the choosing, optimization and evaluation of a milking parlour in two large capacity Estonian dairy farms. The choosing and evaluation of milking parlours parameters is based on the available information and results of previous research in dairy farms in the Estonia, using the mathematical model created in the Czech Republic. Time for milking and final specific direct costs are main parameters which enable evaluation and choosing of suitable milking parlour for the dairy farm. Calculation of the first farm with a capacity of 300 cows showed that in the case of rotary milking parlour with 32 milking stalls total specific direct costs per milking per cow and year would be by 25% higher than in the case of Side by Side milking parlour 2 x 12, but the time for milking would be reduced by about 25%. The second farm with capacity of 1,850 cows is equipped with a rotary milking parlour with 70 milking stalls. There are three milkers. Six milkers would bring shortening of one milking from 6.3 h to 3.3 h while preserving approximately the same total specific direct costs per milking per cow and per year. This milking parlour could be used also for the planned increase in capacity at farm to 3,300 cows. Time of one milking would be 5.6 hours, but total specific direct costs per milking per cow and per year would be reduced by 18%.

Abstract:

The objective of this study was to analyse the energy use by the dairy case-farm with un-insulated cowsheds in Estonia for the period of 2009-2010. The energy balance calculation includes the direct energy input of fuel, lubricants and electricity and the indirect input of forage, cereals, concentrates for young stock, dairy cattle and buildings. Energy outputs are milk, meat, and manure. The energy values were calculated multiplying the quantities of inputs and outputs by their energy conversion factors. The quantitative parameters of the inputs and outputs are based on book-keeping data, the energy conversion factors of feed were measured. The energy output-input ratio of the case-farm was 1.88 in 2009 and 1.85 in 2010. Energy input of milk was 5.4 and 5.3 per MJ kg-1, respectively. Our study indicated that the case farm energy consumption is generally higher than that of comparable European dairy farms. The further research is needed to find the reason of mentioned differences.
