Analysis of nutritional needs for the establishment of a dairy cow and fattening beef farm

Cilj ovog rada je odrediti norme za sve kategorije životinja u mliječnom i tovnom govedarstvu. Također je važno izabrati krmiva koja će zadovoljiti produktivne potrebe goveda te osmisliti gospodarstvo koje proizvodi krmiva na vlastitom poljoprivrednom zemljištu i koje nastoji povećati broj UG po hektaru. Sastavljena su devet obroka: obrok za mliječne krave s dnevnom proizvodnjom od 30 L, obrok za mliječne krave s dnevnom proizvodnjom od 15 L, obrok za krave u prvom dijelu suhostaja, obrok za krave u drugom dijelu suhostaja, obrok za rasplodne junice tjelesne mase 250 kg, obrok za rasplodne junice tjelesne mase 450 kg, Obrok za telad tjelesne mase 150 kg, obrok za tovnu junad tjelesne mase 200 kg i obrok za tovnu junad tjelesne mase 400 kg. Zastupljena krmiva u obrocima: silaža kukuruza, silirani klip kukuruza, sjenaža ljulja, sijeno lucerne, slama ječmena, zrno kukuruza, sačma soje i stočni grašak. Za proizvodnju krmiva na gospodarstvu potrebno je 78,7 hektara poljoprivrednog zemljišta.The aim of this paper is to determine the nutritional needs for all categories of animals in dairy and fattening cattle. It is also important to choose fodder that will meet the productive needs of cattle. Design a farm that produces fodder on it's own agricultural land and that seeks to increase the number of UG per hectare. Nine meals were made: meal for dairy cows with daily production of 30 L, meal for dairy cows with daily production of 15 L, meal for cows in the first part of the dry period, meal for cows in the second part of the dry period, meal for breeding heifers weighing 250 kg, meal for breeding heifers weighing 450 kg, meal for calves weighing 150 kg, meal for beef cattle weighing 200 kg and a meal for beef cattle weighing 400 kg. Feeds represented in meals: corn silage, ensiled corn cob, ryegrass silage, alfalfa hay, barley straw, corn grain, soybean meal and field peas. 78,7 hectares of agricultural land are needed for the production of fodder on the farm
