20.500.12556/DKUM-61590 Rezultati pitanja prašičev v kmečkih rejah – Specializirana prašičerejska kmetija Fattening performance of pigs on family farms – specialised pig farm V diplomski nalogi smo zbirali podatke o pitanju prašičev v kmečkih rejah. Za raziskavo smo izbrali dve specializirani prašičerejski kmetiji (A in B) iz okolice Gornje Radgone. Na izbranih kmetijah smo najprej izvedli anketo in tako pridobili osnovne podatke o kmetiji (hlevih, boksih), živalih, krmljenju, načinu reje. Na vsaki kmetiji smo naključno izbrali po dva boksa in prašiče označili. V času pitanja smo prašiče štirikrat individualno stehtali ter dnevno merili porabo krme (na boks). Krmo smo tudi kemično analizirali. Ob zakolu smo v klavnici izmerili lastnosti klavne kakovosti. V času pitanja so imeli prašiči na obeh kmetijah primerljiv razpoložljiv prostor (precej nad minimalnimi standardi, na kmetiji A dodatno še izpust) in enako število krmilnih mest. Rezultati so pokazali primerljivo kemično sestavo krme (15 MJ metabolne energije, 150 g beljakovin/kg) kot tudi enako konzumacijo krme med celotnim pitanjem na kmetijah (2,51 kg/dan). Kljub temu je bil na kmetiji A dnevni prirast prašičev nižji (753 vs. 833 g) kot na kmetiji B, konverzija pa posledično večja (3,33 vs. 3,01 kg krme/kg prirasta). Zaradi večje mase živali ob zakolu na kmetiji B so imeli ti prašiči tudi večjo maso toplih polovic, sicer pa je bila klavna kakovost na obeh kmetijah primerljiva. Dobljene rezultate (razlike v prirastu in konverziji) lahko pojasnimo z opaženimi slabšimi razmerami v hlevu kmetije A: temnejši, prašen, zadušljiv hlev, le občasna prisotnost obogatitvenega materiala, neustrezne nastavitve krmilnikov in posledično večji raztros krme ter povečana agresija prašičev pri krmljenju. The aim of the present work was to collect the data on fattening of pigs on family farms. Two specialized pig farms (A and B) from the region of Gornja Radgona were chosen. In the first step, a survey was conducted in order to obtain basic information on farms (stables, pens), animals, feeding and rearing conditions. For the experimental step, two pens per farm were randomly selected and pigs were individually weighted four times during fattening. Feed consumption (pen based) was monitored daily and its chemical composition was determined using Weende analysis. Carcass quality traits were also measured at the end of the experiment. During fattening, pigs from both farms had comparable space/floor area (noticeably above the minimum standards, however, pigs on farm A had additional access to outdoor area) and the same number of feeding places. Pigs were offered feed with comparable chemical composition (15 MJ of metabolic energy, 150 g protein/kg) and had the same feed intake during the whole fattening period (2.51 kg/day). Despite that, pigs from farm A had lower daily weight gain (753 vs. 833 g) compared to farm B and consequently higher feed conversion ratio (3.33 vs. 3.01 kg feed/kg weight gain). Higher final live weight of pigs from farm B resulted in higher slaughter weight, however, no differences in other carcass quality traits were observed. Lower weight gain and increased feed conversion ratio on farm A can be explained by poorer housing conditions: darker, dustier, stifling stable, only occasional presence of enrichment material and inadequate feeder settings which resulted in increased feed dispersion and increased aggression during feeding. prašiči pitanje specializirana reja rastnost klavna kakovost pigs fattening specialised farm growth performance carcass quality true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2016-08-11 11:37:27 2016-08-29 13:34:58 2022-06-27 03:05:53 2019-07-11 12:26:29 2016 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:FCRKHQ0K VS_Jurkovic_Valerija_2016.pdf VS_Jurkovic_Valerija_2016.pdf 1 5CEAFB72425EB9FF03DE1A294FA3732D e32b457a0237ccbd5488946ee2fc3db963aa5ba9d44ff810103b97f4b1fc83c2 ff51a631-7c0c-11eb-bb7a-00155d0001ca https://dk.um.si/Dokument.php?lang=slv&id=98232 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
