Abstract

V diplomskem projektu smo predstavili krmljenje telet po volji kot alternativno vzrejo v primer-javi s konvencionalno vzrejo telet, kjer je zauživanje mleka oz. mlečnega nadomestka omejeno. Pri tej vzreji teleta v predodstavitvenem obdobju popijejo tudi do 20 % telesne mase na dan v obliki mlečnega nadomestka ali polnomastnega mleka. Ker je zelo po-membno, da teleta do odstavitve dosegajo čim večje priraste, je potrebno urediti dnevni obrok tako, da teleta lahko zaužijejo o čim več hranljivih snovi. Le te so ključ do hitre rasti in dobrega razvoja vseh organov in organskih sistemov. Potrebno je uskladiti tekoči obrok in od drugega tedna dalje tudi suhi obrok s štarterjem in senom. Pri tem moramo biti pozorni, saj so teleta v glavnem še neprežvekovalci in je njihov glavni obrok še zmeraj tekoča krma. Če to ne upoštevamo, teleta izpostavljamo stresu, posledično manj pojedo in slabše priraščajo. Dobro razvito tele v predodstavitvenem obdobju, običajno tudi po odstavitvi še naprej dobro prirašča, posledično prej spolno dozori in tako rejcu omogoča zgodnejšo reprodukcijo. Rezultat dobre vzreje telet se odrazi tudi na poznejši mlečnosti, saj različni raziskovalci ocenjujejo, da se lahko v prvi laktaciji mlečnost po-veča tudi za do 4 %.

Secondary title:	Ad libitum feeding calves until weaning
Secondary abstract:	In B. Sc. Thesis, we presented ad libitum feeding of calves until weaning as an alternative to conventional restricted milk feeding. In this alternative method, calves can drink up to 20 % of their body weight per day in the form of milk replacer or whole milk during the period before weaning. Since it is very important that calves achieve the highest growth rate possible before weaning, the daily ratio must be managed to allow calves to consume as many nutrients as possible. Nutrients are key to rapid growth and development of all organs and organ systems. It is necessary to coordinate liquid feeding and, beginning in the second week, dry feeding with a starter and hay. Care must be taken as calves are mostly still non-ruminants and their main part of the feed ratio is still liquid feed. If we do not take this into account, calves will be exposed to stress, resulting in lower feed intake and growth rate. A well-developed calf in the pre-weaning period continues to grow well, consequently reaching sexual maturity earlier and also allowing for earlier reproduction. The result of good calf rearing is also reflected in later milk yield, as various researchers estimate that milk yield can increase by up to 4 % in the first lactation.
