METABOLIČKI STRES KOD MLEČNIH KRAVA U RANOJ LAKTACIJI – OPŠTE KARAKTERISTIKE

Abstract

Milk production in dairy cows has increased significantly in the last few decades and continues to increase. The beginning of lactation requires extremely great effort from cows to overcome metabolic stress, so the frequency of cows' illness is the most intense in this period. Significant variations in the adaptive responses to lack of energy and nutrients in this period occur in the body of cows, with numerous endocrine, hematological, immunological and other changes. Therefore, cows should be provided with adequate nutrients for a balanced meal, both in the period of drought and in all phases of lactation.
