Abstract:Namen 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 %.

Title:Monitoring postpartum cow conditions on a specific dairy farm
Abstract:The purpose of the thesis was to monitor and assess the physical condition of dairy cows in the postpartum period. The evaluation, which took place from February to July 2021, included 15 dairy cows. According to the list of planned calvings, the animals were divided into three groups, 5 animals each, and they were evaluated in different time periods after birth. Animals were first evaluated for an average of 19 days after calving, where the mean score was 3.66. The second evaluation was on average 89 days after calving, the evaluation decreased to 3.4. The last, third evaluation was performed on the 145th day after calving, where the average evaluation was 3.43. In the second group, 2 animals were eliminated and died after giving birth. We came to the conclusion that animals lose their physical condition in the first 2 and 3 months, as they are in a negative energy balance. In addition to assessing physical condition, we obtained data on the amount of milk and the content of milk fats and proteins from the AT4 control. Milk fat contents were in accordance with the norms. There were deviations in the protein content, as the protein should fall in the postpartum period, while in our case the protein content increased, which we prescribed for the season. Despite the increase, we are within the norms, as the protein values did not exceed 3.80 %.
