Abstract

Da bi svaka farma krava funkcionirala na željenoj razini, ključno je paziti na nekoliko faktora. Osim higijene i zdravstvene zaštite stada, hranidba je izuzetno važna za svaki aspekt uspješne proizvodnje. Pravilno kategorizirane skupine životinja i njima prilagođena hranidba su ključni za zdravlje životinja i dobru proizvodnju. Bilo kakvi disbalansi u količini hranjivih tvari koje životinja unosi hranom mogu dovesti do potencijalnih probavnih poremećaja i samim time do pada proizvodnje sto je u korelaciji s novčanim dobitkom. U cilju ostvarenja što veće proizvodnje važno je uskladiti odnos proteina, vlakana i energije. Drugi važan aspekt je razmnožavanje životinja, što je osnova za učinkovitu proizvodnju mlijeka. U ovom radu provedena je analiza uvjeta na farmi prije i nakon dolaska stručne osobe. Mjerena je dnevna količina mlijeka prikupljena strojem za mužnju kao i sastav mlijeka koji je određen u Referentnom laboratoriju. Također, pratila se reprodukcija te sastav obroka prije i nakon dolaska stručne osobe te utjecaj same hranidbe na reprodukciju životinja. Dolaskom stručne osobe, sastav obroka je prilagođen potrebama krava po kategorijama, te je samim time povećana dnevna količina mlijeka (za 17%) i reproduktivna sposobnost životinja.

Abstract (english)

In order for each cow farm to function and ultimately lead to profitable yields of good quality, it is crucial to pay attention to several factors. Apart from hygiene and timely treatment, nutrition is extremely important for every aspect of successful production. Properly categorized groups of animals and their adapted diet are key to animal health as well as yields. Any imbalances in the amount of nutrients that the animal ingests can lead to potential digestive disorders and thus to a drop-in production, which is correlated with monetary gain. Having the goal of achieving the highest possible production, it is very important to harmonize the ratio of protein, fiber and energy; it must be adapted to each category. In this Master’s thesis, analysis of farm conditions is performed before and after the expert intervention. Daily quantity of milk is measured by milking machine while the chemical composition is determined by References laboratory analysis. Furthermore, reproduction of cows was followed together with meal composition before and after expert intervention. Meal composition is balanced and adapted to the individual categories resulting in an 17 % milk yield increase. In addition, with proper organization and balanced diet, reproduction is also increased.
