dc.description.abstractData concerning the effect of probiotics supplementation on many parameters concurrently at the same cows are lacking. Therefore, the objective of this experiment was to investigate the effects of Saccharomyces cerevisiae feeding on rumen, blood and milk parameters together in high- producing dairy cattle during the transition and early lactation period. Sixteen clinically healthy Holstein cows were divided into 2 groups: a control group of 6 cows and a probiotics-fed group of 10 cows. Rumen fluid and blood samples were collected 21 days before the expected calving as well as 7, 15, 30, 45 and 60 days- in-milk (DIM). Milk yield for each animal was recorded every 2 weeks. Individual milk samples were collected 15, 30, 45 and 60 DIM. Ruminal pH and rumen ammonia nitrogen were significantly lower, whereas total volatile fatty acids were significantly higher in yeast-fed animals compared with controls throughout the study. Serum concentrations of total proteins and globulins were higher, while albumins were lower in the yeast-treated group. Serum glucose levels were significantly higher in yeast-supplemented animals. Serum triglycerides, high density lipoproteins, and low density lipoproteins concentrations were lower, with cholesterol being significantly lower in the treated group. Milk production and milk fat percentage were higher, whereas milk protein percentage and somatic cell count were decreased in yeast-supplemented cows throughout the study. These results suggest that supplementation of S. cerevisiae to dairy cows rations during transition and early lactation period improve their health and milk production parameters.en
dc.description.abstractPodaci koji bi se odnosili na uticaj suplementacije probiotika na više parametara istovremeno na istim grlima nedostaju u literaturi. Stoga je cilj ovog eksperimenta bio da se ispita uticaj Saccharomices cerevisiae u obroku/hrani na parametre rumena, krvi i mleka zajedno u visoko-proizvodnim mlečnim govedima tokom tranzicije i početkom laktacije. Šesnaest klinički zdravih holštajn krava je podeljeno u 2 grupe: kontrolna grupa od 6 krava i grupa od 10 krava hranjenih probiotikom u obroku. Buražna tečnost i uzorci krvi su sakupljeni 21 dan pre očekivanog teljenja, kao i 7, 15, 30, 45 i 60 dana tokom laktacije (days in milk - DIM). Prinos mleka za svaku životinju zabeležen je svake 2 nedelje. Pojedinačni uzorci mleka su prikupljeni 15, 30, 45 i 60 DIM. pH buraga i buražni amonijačni azot su bili značajno niži, dok su ukupne isparljive masne kiseline bile značajno veće kod životinja hranjenih kvascem u poređenju sa kontrolama kroz celu studiju. Serumske koncentracije ukupnih proteina i globulina bile su više, dok su koncentracije albumina bile niže u grupi sa kvascem. Serumski nivoi glukoze bili su značajno viši kod životinja sa dodatkom kvasca. Trigliceridi u serumu, koncentracije lipoproteina visoke i niske gustine bile su niže, sa holesterolom koji je bio znatno niži u tretiranoj grupi. Proizvodnja mleka i procent mlečne masti bili su viši, dok je sadržaj proteina mleka i somatskih ćelija bio niži u krava hranjenih sa dodatkom kvasca kroz celu studiju. Ovi rezultati ukazuju na to da dodatak S. cerevisiae u obrocima muznih krava tokom tranzicije i rane laktacije poboljšava njihovo zdravlje i parametre proizvodnje mleka.sr
