20.500.12556/DKUM-77123 Vpliv krmnega dodatka vibrosorba na mlečnost, sestavo mleka in zdravstveno stanje krav molznic Influence of the feed additive vibrosorb on milk yield, milk composition and health of dairy cows Na kmetiji Gašperja Zabreta smo izvedli poskus, pri katerem smo dodajali zeolit VibroSORB® v obrok kravam molznicam. Zanimalo nas je, kako krmni dodatek VibroSORB® vpliva na prirejo mleka, njegovo sestavo, obenem pa tudi zdravstveno stanje krav na kmetiji. Tematika diplomskega dela se nam je zdela izredno zanimiva, saj na tem področju še ni veliko raziskanega. Zaželeni cilji poskusa so bili predvsem povečana mlečnost, izboljšana kakovost mleka in s tem povezana odkupna cena, hkrati pa tudi boljše zdravstveno stanje živali. Poskusno skupino so predstavljale krave v laktaciji, ki so v času med 19. 12. 2018 in 8. 3. 2019 dobivale v obrok dodatek zeolita v odmerku 150 g/kravo/dan. Za kontrolno skupino smo vzeli podatke istega obdobja leto poprej, saj se obrok drugače ni spremenil. Molža je potekala s pomočjo robota, ki je sproti beležil vse parametre v mleku, za vsako kravo in vsako njeno molžo. Rezultati statistične analize nakazujejo, da zeolit povečuje prirejo mleka in vsebnost maščob v mleku. Pri količini beljakovin v mleku nismo ugotovili pomembnih razlik. Zdravstveno stanje živali in plodnost krav na kmetiji se nista pomembno spremenila v primerjavi s kontrolnim obdobjem. Glede na rezultate dobljene v tem diplomskem delu, bi bilo smiselno nadaljevati raziskavo, in sicer za daljše obdobje, z večjim številom krav, z različnim načinom dajanja ter različnimi odmerki dodatka. At Gašper Zabret's farm, an experiment with the feed additive VibroSORB® was performed, which is a natural zeolite in dairy cows. It was studied how the additive VibroSORB® in feed affects milk production, the composition of milk and health of cows. Little research has been conducted in this field. It was hypothesised that VibroSORB® will increase milk yield, milk quality and cow health. The experimental group consisted of lactating cows, which received the additive VibroSORB® at a dose of 150 g/day/cow in TMR between 19th December 2018 and 8th March 2019. For the control group, data was taken from the same period the year before, since the composition of TMR did not change otherwise. Milking was carried out robotically and milk yield, milk composition and electrical conductivity of every milking and every cow were recorded. The results of the statistical analyses showed that zeolite increased milk yield and fat content. There were no significant differences in the amount of protein in milk, lactose content and electrical conductivity did not improve. The health status of the animals and their reproductive performance did not improve compared to the control group. Results of the study are however encouraging and further studies on bigger samples of animals, with different amounts, ways of administration and types of zeolite are needed. zeolit VibroSORB® mleko sestava mleka zdravje zeolite VibroSORB® milk milk - quality health true true false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2020-08-18 10:37:40 2020-09-17 11:51:14 2022-08-09 14:23:19 2020-09-18 03:13:00 2020 0 Maribor 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 URN:SI:UM:DK:J5AGWOTK UN_Slatinek_David_2020.pdf UN_Slatinek_David_2020.pdf 1 DC23273E4B19BC57925BC7B0C905F65B 84519aed727a5f55a22feec7d61d59ce9ec05515c3ef9725bbaa3b903ed6ca3f d0d2811e-7c11-11eb-bb7a-00155d0001ca 20.500.12556/dkum/b956d3ef-1bad-4552-aa90-4adc01a0d1b9 https://dk.um.si/Dokument.php?lang=slv&id=145655 Fakulteta za kmetijstvo in biosistemske vede 0 0 0
