Influence of nutrition on the amount and milk content of cow's milk

Mliječna mast je najvarijabilniji sastojak kravljeg mlijeka. Odabir krmiva, veličina čestica, udio i izvor voluminozne krme neki su od čimbenika koji utječu na razinu i sadržaj mliječne masti. Ovaj rad prikazuje na koji način se hranidbom može mijenjati udio i sastav mliječne masti u mlijeku. Na količinu mliječne masti najviše utječe struktura obroka, kvaliteta krmiva koja se koriste u hranidbi, kao i neki aditivi koji se mogu davati u obrok krave. Na sastav mliječne masti, odnosno, masnokiselinski profil u najvećoj mjeri se može utjecati povećanom hranidbom zrnjem uljarica ili dodatkom ulja u obrok.Milk fat is the most variable ingredient in cow's milk. Feed selection, particle size, proportion, and source of bulk feed are some of the factors that affect milk fat level and content. This paper shows how feeding can change the proportion and composition of milk fat in milk. The amount of milk fat is most affected by the structure of the meal, the quality of the feed used in the feed, as well as some additives that can be given in the cow’s meal. The composition of milk fat, that is, the fatty acid profile can be largely influenced by increased feeding of oilseeds or the addition of oil to the meal
