Cow cleanliness in dairy herds with tie stall systems in Bosnia and Herzegovina | Čistoča krav v čredah krav molznic z vezano rejo v Bosni in Hercegovini

Английский. This study involved 70 tie stall dairy herds from all over Bosnia and Herzegovina. In each herd, trained observers scored the cleanliness (score 1 = clean to score 4 = very dirty) of 5 randomly chosen cows, total 350 cows, on 5 different body parts (rear, thigh, leg, udder and belly). Total cleanliness score was calculated by adding together the scores for the different body parts. The observers also recorded data on stall design, flooring and use of bedding materials. The proportion of cows scored as dirty or very dirty (score 3 and 4) was 33.4 %, 50.8 %, 55.1 %, 16.0 % and 18.6 % for the legs, thighs, rear, udder and belly respectively. 57.4 % of the cows got a total cleanliness score > 10. The mean total cleanliness score on herd level varied from 5.2 to 18.8. Tests of each stall design variable showed that tying system (p < 0.05), presence of stall dividers (p < 0.05) and manure system (p < 0.05) had a significant effect on total cow cleanliness, the use of bedding material (p > 0.15) and floor type (p > 0.15) had smaller effect. However, only the presence of stall dividers showed significant association to total cleanliness score in the full statistical model (p < 0.05).

словенский. V študijo je bilo vključenih 70 čred krav molznic z vezano rejo v Bosni in Hercegovini. Čistost krav v vsaki čredi so ocenili usposobljeni opazovalci (ocena od 1 do 4, 1 = čisto, 4 = zelo umazano) na osnovi petih naključno izbranih krav. Skupaj so pri 350 kravah ocenili čistost na petih različnih delih telesa (zadnjica, stegna, noge, vime in trebuh). Skupno čistočo smo ocenili s seštevanjem ocen za različne dele telesa. Opazovalci so zabeležili tudi podatke o tipu stojišč, vrsti tal in o uporabi materialov za nastil. Delež krav, ki so bile ocenjene kot umazane ali zelo umazane (oceni 3 in 4), je bil 33,4 % za čistost nog, 50,8 % za stegna, 55,1 % za zadnjico, 16,0 % za vime in 18,6 % za trebuh. Skupno oceno za čistost > 10 je dobilo 57,4 % krav. Povprečna skupna čistost na ravni črede je bila od 5,2 do 18,8. Analiza različnih tipov reje je pokazala, da so način privezovanja (p < 0,05), razdelilne ograje (p < 0,05) in sistem odstranjevanja gnoja (p < 0,05) pomembno vplivali na čistočo krav, v manjši meri pa vrsta nastila (p > 0,15) in vrsta tal (p > 0,15). V skupnem statističnem modelu je samo prisotnost razdelilnih ograj pokazala statistično značilno (p < 0,05) povezavo s skupno oceno čistosti živali.
