The objective of the present study was to investigate nutritional and metabolic status in Simmental cows during early and mid-lactation. Fifteen early lactating cows and 15 mid lactating cows were chosen for the investigation. Blood samples were collected to measure beta-hydroxybutyrate (BHB), nonesterified fatty acids (NEFA), triglycerides (TG), glucose and the activity of aspartate transaminase (AST). Early lactation as compared to mid lactating cows were found to have significantly higher (P (lt) 0.05) blood serum concentrations of NEFA, BHB and AST and lower blood serum concentrations of glucose (P (lt) 0.05) and TG (P>0.05). Significantly negative correlations were observed between BHB and glucose (P (lt) 0.01), BHB and TG (P (lt) 0.05), NEFA and glucose (P (lt) 0.05). Significantly positive correlations were observed between NEFA and BHB (P (lt) 0.05), NEFA and AST (P (lt) 0.05), glucose and TG (P (lt) 0.01). The results suggest that these parameters can serve as useful indicator...s of the nutritional and metabolic status of dairy cows during lactation.
Cilj ovog rada je bio da se ispita matabolički i hranidbeni status mlečnih krava simentalske rase za vreme rane laktacije i tokom sredine laktacije. 15 mlečnih krava na početku laktacije i 15 tokom sredine laktacije je odabrano za ispitivanje. Uzorci krvi su uzeti i merene su vrednosti za beta-hidroksi-buternu kiselinu (BHB), slobodne masne kiseline (NEFA), trigliceride (TG), glukozu i aktivnosti aspartat-amino transaminaze (AST). Krave na početku laktacije su imale statistički značajno veće koncentracije (P (lt) 0.05) NEFA, BHB i AST u krvi i značajno niže vrednosti za glukozu i trigliceride (P (lt) 0.05). Statistički značajne negativne korelacije su utvrđene između vrednosti BHB i glukoze (P (lt) 0.01), BHB i TG (P (lt) 0.05), NEFA i glukoze (P (lt) 0.05). Statistički značajne korelacije su utvrđene između NEFA i BHB (P (lt) 0.05), NEFA i AST (P (lt) 0.05), glukoze i TG (P (lt) 0.01). Rezultati ukazuju da ovi parametri krvi mogu biti korisni pokazatelji metaboličkog i hranidbenog sta...tusa kod mlečnih krava za vreme laktacije.
