Dynamika koncentrace selenu v krvi krav a telat masného skotu při dotaci organické a anorganické formy selenu a vliv na reprodukční ukazatele zvířat

Original language description

The objective of this study was to compare the effects of feed supplementation with sodium selenite or selenized yeast on serum Se levels and reproduction indicators in cattle. In three beef herds young heifers, cows in latepregnancy, and their calves were randomly grouped by 6. In Herd 1, the mean Se serum levels were 51.01?g.l-1 in heifers, 32.12?g.l-1 in cows in latepregnancy, and 29.07?g.l-1 in their calves. In Herd 2, 27.42?g.l-1 (heifers), 22.9?g.l-1 (latepregnancy), and 23.46?g.l-1 (calves). In Herd 3, 27.07?g.l-1 (heifers), 22?g.l-1 (late pregnancy cows), and 31.05?g.l-1 (calves). Over a 6-months period, the animals in Herd 1 were given selenium yeast supplement; in Herd 2 sodium selenite, whereas Herd 3 served as a negative control. Afterwards, a second blood sample was taken. The mean Se serum levels were as follows: Herd 1(selenium yeast): 90.73?g.l-1 in late pregnancy cows ( p < 0.01), 57.99?g.l-1 in calves ( p < 0.01); Herd 2 (sodium selenite): 42.08?g.l-1 (latepregnancy c
