| Description
| - Cílem pokusu bylo zhodnocení vlivu vysoké koncentrace tuku v krmné dávce, podávaného ve formě vápenatých solí mastných kyselin z řepky olejné na metabolismus a užitkovost dojnic v první třetině laktace. Do pokusu bylo zařazeno 28 dojnic, rozdělených na skupinu pokusnou (E; n = 14) a kontrolní (C; n = 14), které byly sledovány od porodu do 100 dní laktace. Krmná dávka obou skupin měla vyrovnaný obsah energie a dusíkatých látek, rozdíl byl v obsahu tuku (C - 3.7 % vs. E - 6.99 % sušiny krmné dávky). Celková produkce mléka za 100 dní laktace byla obdobná u obou sledovaných skupin. U pokusné skupiny byla koncentrace proteinu nižší (3,18 vs. 3,45 %, p≤0,01) a koncentrace tuku nesignifikantně vyšší (3,55 vs. 3,21 %). Na základě našich výsledků představuje zkrmování vyšších dávek tuku (6,99 %) v bypass formě zdravotní riziko vzniku steatózy jater v prvním měsíci po porodu, ale na vrcholu laktace již negativní vliv na zdravotní stav dojnic zjištěn nebyl.

- The purpose of this experiment was to evaluate the influence of high lipid concentration in the diet on metabolism and milk yield of dairy cows in the first third of lactation. 28 dairy cows were divided into experimental E and control C groups and monitored within 100 days of lactation since the day of parturition. The diet of both groups had balanced content of energy and crude protein, while the difference was in lipid content (C - 3.7 % vs. E - 6.99 % of dry matter in the diet). The total production of milk within the 100 days of lactation in both monitored groups was similar. In the group E the concentration of milk protein was lower (3.18 vs. 3.45 %, p≤0.01), while concentration of fat was non-significantly higher than in the group C. Our results reveal that the feeding of higher doses of lipid fed in bypass form during the first month after parturition creates the health risk of fatty liver, but no negative impact on the health of dairy cows was found during the peak period of lactati
