Spremljanje kondicije krav v poporodnem obdobju na izbrani kmetiji, usmerjeni v prirejo mleka : diplomsko deloŠkrlec, AnjaNamen diplomskega dela je bil spremljanje in ocenjevanje telesne kondicije krav molznic v poporodnem obdobju. V ocenjevanje, ki je potekalo od meseca februarja do julija 2021, je bilo vključenih 15 ... krav molznic. Glede na seznam predvidenih telitev smo živali razdelili v tri skupine po 5 živali in jih ocenili v različnih časovnih obdobjih po porodu. Prvič smo živali ocenili v povprečju 19. dan po telitvi, kjer je bila povprečna ocena 3,66. Drugo ocenjevanje je bilo v povprečju 89. dan po telitvi, ocena se je zmanjšala na 3,4. Zadnje, tretje ocenjevanje smo opravili 145. dan po telitvi, kjer je bila povprečna ocena 3,43. V drugi skupini je prišlo do izločitve dveh živali, ki sta po porodu poginili. Prišli smo do ugotovitve, da živali v prvih dveh in treh mesecih izgubljajo na telesni kondiciji, saj so v negativni energijski bilanci. Poleg ocenjevanja telesne kondicije smo iz AT4 kontrole pridobili podatke o količini mleka in vsebnosti mlečnih maščob in beljakovin. Vsebnosti mlečnih maščob so bile v skladu z normativi, pri vsebnosti beljakovin pa je prišlo do odstopanj, saj bi beljakovine v času po porodu morale padati, pri nas pa se je vsebnost beljakovin povečevala, kar smo predpisali letnemu času. Kljub povečanju vrednosti beljakovin niso presegale 3,80 %.Type of material - undergraduate thesis ; adult, seriousPublication and manufacture - Maribor : [A.
