20.500.12556/DKUM-75324 Različne oblike obnašanja pujskov in njihova povezanost s tipom tehnologije reje v času laktacije Difference in Piglet Behavior Related to Rearing Technology During Lactation Cilj raziskave je bil preučiti socialne interakcije pujskov s poudarkom na agresivnem obnašanju v času laktacije in sicer v individualnem in skupinskem sistemu reje (odprti prasitveni boksi). V raziskavo smo vključili 53 pujskov iz petih gnezd in sicer 28 v skupinskih in 25 v individualnih boksih. Pujski so bili ustrezno označeni in tehtani na 1., 3., 7., 10., 14., 21. in 28. dan laktacije. Na videoposnetkih smo ob omenjenih dnevih proučevali v času med 8:00 – 12:00 uro osem različnih oblik interakcij (borba za sesek, odrivanje z rilcem, igrivostno odrivanje z rilcem, zaganjanje, grizenje ušes in repa, zaskok, grizenje glava – glava, spopad) med pujski. Pujskom smo določili tudi socialni rang po Schlichtingu in njegovo povezanost s telesno maso in dnevnim prirastom pujskov. Modificirali smo poskusno bipolarni 5-faktorski model (FFM), ki je vsakemu pujsku določil tip osebnosti. Rezultati so pokazali, da so imeli pujski z večjo telesno maso in intenzivnejšo rastjo visok socialni rang. Skupinski sitem v primerjavi z individualno rejo pujskov v času laktacije je imel številne pozitivne učinke na razvoj širšega nabora vedenjskih vzorcev pujskov, kar je imelo za posledico večjo prilagoditveno sposobnost pujskov. Raziskava nakazuje, da je pri pujskih skupinski sistem reje spodbujal pozitivne vidike osebnosti (igriv značaj) in je zaviral razvoj antagonizma (intenzivne, dlje časa trajajoče borbe). Pri aplikaciji skupinskega sistema v rejo pujskov v laktaciji moramo biti pazljivi pri izenačenosti pujskov različnih gnezd v njihovem številu, starosti in telesni masi ter dneva, ko pujskom omogočimo prehajanje med porodnimi boksi in srečevanje na hodniku. The aim of the study was to investigate the social interactions of piglets, with an emphasis on aggressive behavior during lactation in individual and cross-fostering rearing systems. A total of 53 piglets from five litters were included in the study, 28 in a group and 25 in individual boxes. The piglets were weighed on days 1, 3, 7, 10, 14, 21 and 28 of lactation. During those days between 8:00 and 12:00 o'clock, eight different characteristics of social interactions (teat competition, head to head knocking, head to head knocking – playing, head thrust, biting of ears/tail, mounting, head biting and fighting) between piglets were filmed on video. The piglets’ social rank was determined according to Schlichting and its relationship with body weight, and the daily weight gain of the piglets was estimated. A modified bipolar 5-factor model (FFM) for a specific type of piglet personality was assigned. Piglets with higher body weight and more intensive growth had a higher social rank. The cross-suckling rearing system compared to an individual had beneficial effects on the development of a wider range of behavioural patterns of piglets, resulting in their greater adaptive capacity. The study suggested that the cross-suckling rearing system encouraged positive aspects of the piglets' personality (playful character) and reduced the development of antagonism (i.e. intense, prolonged fighting). In conclusion, special care has to be taken when applying the cross-suckling system, especially on equalizing litter size, piglet age and body weight, as well as the time when gates of farrowing pens are opened for the piglets. laktacija / obnašanje pujskov / socializacija / agresija / osebnost lactation / piglet behaviour / socialization / aggression / personality true true false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2019-10-16 07:07:48 2019-11-11 09:00:00 2022-08-09 11:12:03 2019-12-10 08:32:35 2019 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:I6ISPCXD MAG_Gliha_Anej_2019.pdf MAG_Gliha_Anej_2019.pdf 1 145B5428BE3FC1C52076354D550970D5 658c4f2d8053015e0ac297c91019ed40af32b5dd7d9bae18dc112ea30b419776 1dddc2a9-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/7ece062d-5aac-4940-a6e9-7d76e9b2c83a https://dk.um.si/Dokument.php?lang=slv&id=139312 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
