equipment for mechanization of technological
treatments were in cow shed with deep litter
(number 1) and amounted 14858,43 PLN∙LU-1. On
the second place regarding of unitary investments
costs of equipment were cow shed number 10 with
three robots (one for milking, one feed-pusher, one
floor scraper) and amounted 13389,04 PLN∙LU-1.
The lowest unitary investment’s cost of technical
equipment was in boxed cow shed with litter (number
6) and amounted 5708,59 PLN LU-1. Cowsheds which
are complying with requirements for 1st criterion
(unitary investments, both building’s and equipment’s
costs ≤19 000 PLN∙LU-1) : 2, 3, 4, 6, 8, 11 and 12.
Unitary daily labour inputs on all technological
treatments were the highest in cubical cow shed with
litter with the lowest number of cows and amounted
7,25 working hours per LU-1. The lowest unitary daily
labour inputs were in cow shed with two milking
robots and one feed pusher and robot- slatted floor
cleaner (number 9). Cowsheds which are complying
with requirements for 2nd criterion (average unitary
daily labour inputs ≤ 4,6 working hours per LU): 2, 6,
8, 9, 10 and 12.
Average carbon dioxide concentration amounted
from 626,47 ppm to 1500,8 ppm in cowshed without
litter (number 12). Average ammonia concentration
amounted from 1,82 ppm in cowshed with deep litter
(number 4) to 13,84 in boxed cow shed with litter
(number 7). Cowsheds which are complying with
requirements for 3rd criterion (average ammonia
concentration ≤ 10,9 ppm, average carbon dioxide
concentration ≤ 1500 ppm): 1, 3, 4, 5, 6, 8, 10, 11 and 12.
Average electric energy inputs for
four technological treatments were from
0,208 kWh•day-1•LU-1 to 0,827 kWh•day-1•LU-1.
Cowsheds which are complying with requirements
for 4th criterion (average daily unitary electric energy
inputs ≤ 0,40 kWh): 2, 3, 4, 6, 5, 7, 8, 11, 12.
Average mechanical energy inputs amounted from
1,172 (boxed cow shed with litter -number 8) to 3,427
HP day-1•LU -1 (cowshed with deep litter – number 1).
Cowsheds which are complying with requirements for
4th criterion (average unitary daily mechanic energy
inputs ≤ 2,006 HP): 2, 3, 5, 6, 8, 9, 10 and 12.
Summarising, the best solutions were boxed
cow shed with litter (number 8) and boxed cowshed
without litter (number 12). The robotized cowsheds
(number 9 and 10) had the highest electric energy
inputs and investments costs with the lowest human
labour inputs.
On the basis of results there were eight examples
elaborated: two cross-sections of cows sheds for 40 up
to 80 milking cows and three functional–technological
schemes and cross-sections of: 1) cow shed with deep
litter for 75 milking cows; 2) boxed cow shed without
litter for 100 milking cows; 3) boxed cow shed with
litter for 124 milking cows.
