20.500.12556/DKUM-90328 Dobro počutje telic različnih starosti v dveh sistemih reje magistrsko delo Evaluation of Heifer Welfare in Two Different Rearing Systems Dobro počutje domačih živali, ki je premisa sodobne živinoreje, je močno odvisno od sistema reje. V govedoreji je sistem vezane reje še vedno zelo pogost, čeprav zaradi omejene možnosti gibanja velja za manj primernega. Alternativa temu sistemu je kot minimalni standard predlagana hlevska prosta reja, ki živalim omogoča prosto gibanje na omejenem območju. Čeprav se zdi samoumevno, da je prosta reja boljša od vezane, še vedno ni raziskav o tem, ali to velja za vse kategorije in starosti govedi. Namen raziskave je bil primerjati dobro počutje telic v vezani in prosti reji v obdobju pitanja pri različnih starostih. Raziskava je vključevala pet telic v vsakem sistemu na ponovitev (skupaj 20 živali). Počutje telic smo ocenili z uporabo protokola Welfare Quality®, ki vključuje oceno štirih opazovalnih področij: krmljenje, bivalni pogoji, zdravje in obnašanje. Meritve in opazovanja živali in hleva se pretvorijo/preračunajo v ocene dobrega počutja od 0 (neprimerno stanje) do 100 (optimalno stanje). Ocenjevanja so bila izvedena sedemkrat v obdobju pitanja (7–27 mesecev starosti) v trimesečnih intervalih. Rezultati so pokazali značilne razlike v ocenah dobrega počutja živali med vezano in prosto rejo le pri bivalnih pogojih ter tendenco razlik pri obnašanju. Pri obeh področjih so bile ocene razmeroma nizke v primerjavi s področjem krmljenja in zdravja živali, kjer med sistemoma reje ni bilo ugotovljenih razlik. Tudi časovna dinamika ocen meril in področij je bila značilno različna le pri bivalnih pogojih. Pri obeh sistemih reje so se vrednosti s starostjo zmanjševale. V sistemu proste reje so bile ocene pri mladih živalih skoraj optimalne (> 90), a so se s starostjo hitro znižale, v sistemu vezane reje pa ocene niso bile optimalne že pri mladih živalih (≈ 40). Rezultati kažejo, da je vezana reja manj primerna z vidika dobrega počutja živali zlasti za mlade živali. Zaradi tega je priporočljivo, da se mlade živali, če sta v vzrejnih objektih na voljo oba sistema, nastanijo v ograde s prosto rejo. The welfare of domestic animals is a premise of modern livestock farming and depends strongly on the rearing system. Tied rearing system is still the most widespread system in cattle farming, although it is considered less suitable due to the restricted freedom of movement. As an alternative to this system, free-stall rearing, which allows movement, is proposed as a minimum standard. Although it seems self-evident that free-stall rearing is better than tied rearing, there is still a lack of research on whether this is true for all categories and ages of cattle. The aim of the present study was to compare the welfare of heifers in tied and free-stall system at different ages. The study comprised five heifers per rearing system per repetition (20 animals in total). The data were collected using the Welfare Quality® protocol, which includes the assessment of feeding, housing, health and behaviour. Measurements and observations on the animals and the barn are then converted/calculated into scores from 0 (unsuitable conditions) to 100 (optimal conditions). The assessments were carried out 7 times during the fattening period at 3-month intervals. Significant differences in welfare scores were found between tied and free-stall systems only in terms of housing and the tendency of differences in behaviour. For both, the scores were relatively low compared to feeding and health, where no differences were found between the rearing systems. In terms of temporal dynamics, differences were only found in housing, with values decreasing with age in both rearing systems. In the free-stall system, the scores were almost optimal in young animals (>90), but decreased rapidly with increasing age, while in the tied housing system, suboptimal welfare scores were already observed in young animals (≈40). The results confirmed tied stall as less suitable in terms of animal welfare, especially for young animals. It is therefore recommended that young animals should primarily be housed in a free-stall pens if both systems are available in the farm. dobro počutje živali govedo telice sistem reje protokol ocenjevanja animal welfare cattle heifer rearing system assessment protocol true true false E.
