20.500.12556/DKUM-67793 Rezultati pitanja prašičev v kmečkih rejah Fattening performance of pigs on family farms Cilj diplomskega dela je bil spremljati pitanje prašičev v dveh kmečkih rejah pri različnem krmljenju. Pitanje prašičev smo v obdobju enega turnusa (4 mesece, od 20 do 130 kg) spremljali na dveh prašičerejskih kmetijah. Na kmetiji L smo spremljali 5, na kmetiji K pa 6 prašičev. V času pitanja smo prašiče individualno tehtali, ter izračunali dnevne priraste. Odvzeli smo vzorce krme za kemijsko analizo, ter dnevno spremljali porabo le te. Krma na kmetiji L je vsebovala 104 g surovih beljakovin (SB) in 16,30 MJ metabolne energije (ME) na kg suhe snovi (SS), krma na kmetiji K pa 200 g SB/kg SS in 15,03 MJ ME kg SS. Obrok na obeh kmetijah je glede na normative vseboval zadostno količino energije v obroku. Obrok na kmetiji L je v vseh treh obdobjih vseboval premajhno količino SB, medtem ko je bila vsebnost SB na kmetiji K v prvem obdobju ustrezna, v naslednjih dveh obdobjih pa celo nekoliko prevelika. Na kmetiji L so prašiči priraščali skoraj 600 g na dan, povprečno so zaužili 2,19 kg krme, konverzija krme je znašala 3,67 kg/kg prirasta. Na kmetiji K so prašiči priraščali 730 g na dan, dnevno so zaužili 1,87 kg krme, konverzija krme je znašala 2,66 kg/kg prirasta. Ker so bili pogoji bivanja prašičev na obeh kmetijah podobni, smatramo, da so boljši rezultati pitanja (večji prirasti in boljša konverzija) na kmetiji K posledica večje vsebnosti SB v krmi. The aim of the study was to monitor the feeding of pigs in two farm in different feeding. Fattening of pigs was monitored in a period from 20 to 130 kg on two farms. Five pigs were monitored on farm L and 6 pigs were monitored on farm K. The pigs were individualy weighed during the fattening and daily gains were calculated. Feed samples were taken for chemical analysis and feed allowance was monitored. Feed on farm L contained 104 g crude protein (CP) and 16.3 MJ metabolizable energy (ME) per kg dry matter (DM). On farm K, the feed contained 200 g CP/kg DM and 15.03 MJ ME/kg DM. Energy content of the diets was according to the requirements adequate on both farms. As considers CP, its concentration on farm L was too low. On the other hand, feed on farm K had appropriate CP concentration in the first phase of fattening, while the concentration of CP in the following phases even exceeded the requirements. Pigs on farm L gained almost 600 g per day, consumed 2.19 kg feed per day, feed conversion ratio was 3.67 kg/kg gain. On farm K, daily gain of pigs was 730 g/day, feed consumption was 1.87 kg feed/day and feed conversion ratio 2.66 kg/kg gain. As housing conditions were comparable on the farms, we can assume that better performance (higher daily gains, better feed conversion) of pigs on farm K is a consequence of higher CP content in feed. prašiči / kmečka reja / rastnost pigs / family farm / growth true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2017-08-30 22:39:56 2017-09-08 14:34:45 2022-08-01 14:27:34 2019-07-11 16:31:37 2017 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:QPXMR9XO VS_Robic_Ana_2017.pdf VS_Robic_Ana_2017.pdf 1 6750887A49A355DE772709D0D9E46C2C 0de424102907eace00c6e91bce011a6102e383cf12d03a9183379d7b7a648dfb 9739c3c8-7c0e-11eb-bb7a-00155d0001ca 20.500.12556/dkum/8b72af54-236c-4376-b285-cf606ddda8a9 https://dk.um.si/Dokument.php?lang=slv&id=116492 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
